We had a truly wonderful experience with Stello Homes! Our home-buying journey took place over the course of three years, with periods where we paused and resumed our search — and throughout it all, the Stello team remained supportive and patient.

Our agent, Tara Ricciardelli, was incredibly sweet, diligent, and attentive from beginning to end. She always made us feel heard and never rushed, no matter how long the process took. We couldn't have asked for a better guide through such an important milestone.

Beyond helping us purchase our new home, Stello Homes also supported us years ago when another property we own suffered a minor flood. Their team helped us with the floor restoration, and that positive experience was one of the reasons we returned to them for our home search.

Thank you to Tara and the entire Stello team for your professionalism, kindness, and unwavering support. We are so grateful and would highly recommend your services to anyone!

We hired StelloHomes to help us build a mudroom space into our home as we prepare to welcome baby #5—we needed help getting organized and eliminating clutter! From start to finish, Zach and his team were exceptional.

Zach was a pro at walking us through the design process, ensuring we got the biggest bang for our buck. Communication was clear, and he set expectations upfront, which made the entire experience stress-free. His crew was phenomenal—they showed up every day, worked hard, and were incredibly skilled. Any design or build question was brought to us with multiple well-thought-out solutions, making decision-making easy.

What really stood out was how excited and engaged the team was in their work. They were incredibly thoughtful about durability and functionality, knowing that our big family would be putting this space to the test! They also added extra value throughout the project, including a brilliant attic space idea above the garage.

We are beyond happy with our new mudroom and look forward to working with StelloHomes again on our next project. If you’re looking for a solutions-based renovation partner who truly cares about craftsmanship and client satisfaction, we highly recommend StelloHomes!

From my real estate agent to transition coordinator, Stello Homes services exceeded my expectations. They'll have my business for life. I highly recommend them to anyone. Ask them the tough questions and get out of their way. They'll aren't afraid to get in the trenches with you and fight to solve any problem you have encounter. I give a big thanks to the team that supported me through the acquisition process. You will not regret working with them.

We used Zach and the team at Stello homes as our listing agent for our home in Sterling, VA. They had recently listed and sold the home right next door to us.
The whole process was smooth, communication was clear and concise, and like our neighbors, we sold in one weekend well over list with several competing offers.
Zach did a great job negotiating with the various interested buyers agents and we feel confident we got top dollar for our home.

The Stello team took our vision for a updated basement and made it real! The design support was on point and made the process of selecting from thousands of options extremely manageable as she always came with a narrow range of options that perfectly aligned with my style. The on-site crew was highly detail oriented and always came to us with feedback and necessary questions before proceeding with work. We definitely intend to work with them again...hopefully soon!

Outstanding experience working with Stello Homes. Zach is an invaluable source of knowledge and help, and once we got closer to closing, Sarah was extremely helpful in ensuring that we had all of the fine details sorted out and our "ducks in a row". 5/5 would work with them again any time!

We worked with Zach and Stello Homes to find a new house and the experience from start to finish was fantastic. They are thorough, knowledgeable and always available to help with any questions that arise. I would highly recommend using Stello Homes for any of your buying needs if looking for a realtor.

Zach and his team renovated our fireplace. They added a brick tile, reframed the box to fit an insert and installed a new mantel. The finished product looks very pretty. When there was a small issue with the trim, they came back and fixed it. We are pleased with our new fireplace. It gives the room a facelift.

I recently hired Stello Homes, led by owner Zach Costello, for a complete remodel of my 1950s basement, and I couldn't be happier with the outcome.

From start to finish, Zach and his team demonstrated professionalism, expertise, and a commitment to excellence. They transformed my outdated space into a modern, functional area that vastly exceeded my expectations.

Their craftsmanship was exceptional, and communication throughout the project was seamless. I highly recommend Stello Homes for any home renovation needs. In fact, they are the ONLY company I recommend for renovations of any size.

Two-Story Addition: My husband and I hired Stello Homes when we decided to expand our home and finally get the dream primary suite. Ted, Alexa, Leonardo and the rest of the crew worked hard to make sure we designed our spaces with stylish functionality, and they executed it beautifully (family room, powder room & primary suite).

The speed in which they worked was impressive and did not go unnoticed by us and our neighbors. Even with a few changes during the project, they managed to prevent extending the timeline. The communication with our project manager, Ted, was reassuring. He was easily accessible and always happy to take our many questions. His knowledge of all the trades was remarkable.

We’ve already recommended Stello Homes to neighbors and are proud to show off our new home as proof of their high-quality work.

I have been beyond impressed with the services the team at Stello Homes has provided. I have used them for rental management, renovation work, and a new home search! I've mostly worked with Ted Watkins, and first and foremost he is a great person and is very knowledgeable and professional. Anytime you are dealing with your home and or real estate investments, you want a team that cares for and treats the process as if they were doing this for their own family. This is exactly how my wife and I have felt working with Ted and the team at Stello homes. Highly recommend and thank you Stello Homes!

We had a great experience with Stello homes. We worked with Zach and Ted to work through the various details involved in the reconstruction process following extensive tree damage to our home. Stello was willing to work with our insurance company's timeline on various payment schedules, which helped tremendously. Ted was our Project Manager and maintained a great line of communication throughout the entire process. We had many questions and Ted took the time to answer every single one to ensure that we understood what would be happening with the many aspects of the project. Stello was also willing to work with a couple of subcontractors that we chose for certain aspects of the project, which was great. Overall, it was a fantastic experience and helped offer peace of mind during a stessful and lengthy reconstruction process. We would definitely recommend Stello Homes to anyone looking for a quality Home Renovation company.

Fantastic experience with Stello Homes! My wife and I were looking to renovate a bathroom for our house that was built in 1950. Zach provided us several options for the space and walked us extensively through all the detail prior to the project start.

It was a major amount of construction, but the project manager, Grover, was amazing in working with us to make sure nothing was disruptive to our daily routines. More importantly, it looks absolutely amazing. We can't believe the space was able to be transformed to a completely modern bathroom. We will definitely use Stello again!

Zach, Alexa and the team were extremely responsive and flexible through out the entire renovation. The kitchen is better than we could have imagined!

Stello Homes is great to work with! They did an amazing job with new floors, painting, and a ton of other work around our house. I would recommend them to anybody looking to remodel in the area. They also remodeled our whole kitchen, master bath, and walk in closet. They rock and are very easy to work with!

If you are looking to buy or sell a home, work with Stello Homes! As first time homebuyers, the Stello Homes team could not have been better! They walked us through the entire process from start to finish, and were incredibly communicative. Finding the right real estate agent is so important - Stello Homes was right for us, and will be right for you too!

Had my master bath renovated. Stello Homes was right there, start to finish. They competed the work two days ahead of schedule! Their designer Tara was a huge help, and their crew of renovators went above and beyond. I would gladly use them again, and highly recommend them. Worth every penny.

We hired Stello Homes for a lower-level renovation (full basement reno, laundry room, and converting a half bath into a full bath) after hearing about them through our neighbors, who had used them to renovate two of their homes. It was a seamless process from start to finish and we couldn't be happier with the results. The entire team is courteous, knowledgeable, professional, and a pleasure to work with. We give them our highest recommendation.

Buying with Stello Homes could not have been a better experience! As a first time home-buyer, they made the process super easy to understand and were there to assist every step of the way. Ted Watkins is the man! He’s super knowledgable and responsive, wasting no time to get back to us and work with the selling agent on what was needed. His expertise on home repairs/maintenance was like having a home inspector with us on each walk-through. I can’t recommend him highly enough as an agent. Stello Homes also has an incredible business manager in Sarah Willacker. Her attention to detail, efficiency and organization made the process of signing documents, communication, and all the nitty-gritty details a breeze. If you’re in the market to buy, sell or remodel, there isn’t a better choice than the team at Stello Homes!!!

My husband and I have worked with Stello Homes to purchase three homes and each experience has been professional and seamless.

Zach and his team go above and beyond to make the process as simple and quick as possible. We have even recommended Stello Homes to other friends and family. They work hard and make you feel like a valued customer!

My Realtor, Teddy Watkins was awesome to work with and helped me find my dream home in Arlington, VA! He walked me through the process every step of the way and was always super responsive. I truly think the negotiation piece was one of his strongest points. He knows the market and how much to push without making a seller walk away.

Since I am in a busy season of life, he communicated with my mortgage company and let me know what deadlines I had, reminded me to change utilities, etc.

Closing was seamless thanks to his help. He also mentioned that Stello Homes can take care of any remodeling work I want done in my new house.

Teddy went above and beyond throughout the process and I would highly highly recommend him to anyone who is purchasing or remodeling a home!

We did a renovation of our entire first floor and Stello homes did an amazing job.

We used Stello Homes to build a deck on the back of our house. The work was done in a very timely manner and completed exactly when the contractor told us it would be done. The contractor's response time to the questions/concerns I had about design, materials, etc. was quick, and it was always evident that he had done the extensive research required to work around hurdles like septic lines and property lines to give us the biggest deck possible. He was very knowledgable about materials and our options to give us exactly what we wanted - customizing to meet some very specific requests - at the best price. We're so happy with the final result; I look forward to our next project with Stello Homes.

Stello Homes made our vision for a total main level renovation come to life! Zach Costello was responsive from the get-go, giving us creative design solutions within our budget. Work started on-time, as promised, and the foreman (Jimy), who was on site EVERY DAY, was in constant contact with Zach AND us, ensuring that the design was carried-out and even improved along the way. With a new kitchen, floors, stairs, and railings, we feel like we have a brand new house! You can definitely trust Zach and Stello Homes with your own home!!

My family and I could not have had a better experience than what Zach and his team at Stello Homes provided for us when our bathroom needed an update. Zach was incredibly helpful, informative and thorough during our communications leading up to when construction began. The job required work in our second floor bathroom as well as the living room underneath. The team did a great job of keeping the work areas clean during the job and the finished product was even better than we hoped. I will certainly be looking to Stello Homes for future work on our home and highly recommend them to other family and friends.

Zach, Ted, and Sarah helped my wife and I buy our new home in Manassas. They were fantastic every step of the way providing a helping hand no matter what we needed. The incredible thing about them is their round-the-clock dedication. Oftentimes, crucial decisions would need to be made at inconvenient times (nights, weekends, holidays etc.) and they would constantly make themselves available to walk us through our options. Zach and Ted are also very strategic and play the chess match very well making them a crucial resource for a buyer in a sellers market when competition is red hot. They're also very detail oriented. Walking through a house there's nothing they'll miss. Finally, even after you have bought your home you can rely on these guys as a constant source of valuable information from recommendations to first time home-owner tips. These guys can answer just about any question you throw at them and if they don't know, they'll find out for you. Give them a call.

The experience my husband and I had as first-time home buyers with Stello Homes was smooth, easy, and efficient. Zach and his team are friendly, kind, and responsive - we felt cared for the whole time, and never had any worries about missing steps or details. They were our advocates and helpers the whole way. Thank you Stello Homes!!

5 stars truly does not capture how great Zach and his team are. My family and I just moved into our forever home and that’s thanks to Zach and his team. Throughout the entire process, Zach was knowledgeable, responsive and went above and beyond. Trust is important during the home buying process, especially for first time homebuyers, and we had and have complete trust in Zach. He was with us every step of the way and guided us smoothly. As my wife has told Zach, “you can’t get rid of us that easy, we are going to work with you and your team for remodeling” and we wouldn’t want it any other way!

Amazing experience with Stello Homes! They made my process as easy as possible and truly took any and all stress from me. They kept me in the loop with any and all changes; communication was top notch! Not only have they helped me secure the house of my dreams but they are also ensuring the sale of my current house goes smoothly with many proactive measures. Just amazing all around!

We worked with Zach as first time buyers. Even though the 2021 market was insane we were able to buy a house in approximately 12 weeks. We liked that Zach was patient, honest, and detailed when we asked him questions. One of the reasons we chose him was his added background in construction. It helped make decisions since most homes in the current market were being sold with zero contingencies. He wasn't pushy and was willing to work with us as his schedule allowed. He is professional and responsive. We would definitely recommend him.

Zach and the Stello Homes team recently remodeled our guest bathroom. Zach was professional and responsive throughout the process, from helping us to pick finishes through questions we had before, during, and after the renovation. We are beyond happy with the results. His team showed up promptly at the agreed time every day, kept our house clean, and wore masks throughout.

I’d recommend the Stello Homes team to anyone in the northern VA area!

Zach was great! My wife and I were feeling a bit overwhelmed putting our first home on the market, so we asked Zach for his expertise. We took some time to speak with him on our goals and he went above and beyond. He was thorough, patient, and calm the whole time as he guided us on the prep work to put our house on the market. Zach was always responsive for a quick phone call or text and calmed our nerves whenever we had some questions. We also appreciated him coming by several times to our house as work was getting done on it to check in with us. Not only did it sell instantly, but we got a great deal with with a long rent-back period, which took the stress out of us having to get out of the house quickly. We are very happy with the outcome and absolutely recommend him for anyone with house needs. He was a pleasure to work with!

Zach helped us update our home, sell much higher than we thought we would be able to with a rent back period to allow us to find a new home at the right price and in the right timeframe. He has been professional and responsive throughout the process even when we changed things at the last minute. He has gone above and beyond to give us the full Stello Homes service and we could not be happier!

Zach has made our house sale and purchase flawless. Spending time with us before listing the house to work through what we should update to get the best ROI, finding our dream home before it even hit the market, and now doing a basement build out on the new house.
We would not be in this perfect situation if not for the guidance and professionalism Zach has shown. We have already recommended him to other friends and family and will continue in the future.

Johanna M.
Jan 3, 2021

As a first time home buyer I had ZERO clue what I was doing but Zach was incredibly knowledgeable and patient as we went through my home search. He also has a rolodex of recommendations for any home needs including loan company, plumbers, electricians - really anything you'd need! We managed to find my perfect home. Knowing I could trust Zach to look at the "boring" stuff (HVAC, water heater, etc) while I focused on the pretty hard wood floors was key.

Highly recommend for your first or fifth home buying needs!

Cristina Perez
Oct 29, 2020

Our experience with Zach was excellent!. We were selling our house of 20 years and looking for our new home! Zach set our house up for success to see at top dollar. He then spent hours researching, sitting in builder meetings, walking lots, asking questions, writing contracts, and viewing houses. We were able to find the perfect home with Zach's guidance. We highly recommend Stello Homes!

This was the best contractor experience I’ve ever had. We did a large scope of work with Zach and team and they hit it out of the park. Zach is extremely customer focused and his goal is to satisfy. He and his crew are always professional and his manner of engaging puts you at ease. When encountering issues he stayed calm and focused on making sure we got what we asked for. Value overall is outstanding. In our case the team worked long hours to complete our project while we went on a long vacation and it was greatly appreciated. I recommend Costello Homes without any qualification. Honest, reliable, friendly, professional. Great job!

Zach and the rest of the Stello Homes team blew us away. Buying our first home , we were pretty nervous but Zach's expertise and guidance really made us feel at ease. We competed against 5 other offers and won out at a sales price under what we were expecting to pay. We're also excited to get some remodeling done with Stello Homes before we move in. I'm sure that will be great too. Stay tuned!

Zach was a great agent! I always worried about being too needy but every question we had or house we wanted to see, Zach happily worked with us to make sure we had everything we needed/answer our questions. We had some hiccups that came up during the process but he walked us through every step and quelled our anxieties along the way. Highly recommend!

Luisanna Timmons
May 22, 2020

We can’t speak highly enough of our experience with Zach Costello and the Stello Homes team! As our Realtor, he helped us find the right house in the right neighborhood for the right price. He was patient as we traveled from Savannah, GA to look at homes over several months and often Facetimed us for virtual tours of potential listings.

The best part of working with Zach was that he was always so thorough about his knowledge of home construction and the local market. Every time we viewed a new property Zach would perform a methodical inspection, looking for signs of problems and commenting on the quality of construction, finishes, appliances, etc. He also cautioned us about making unreasonable offers when we fell too quickly for overpriced homes.

If you are a buyer or seller I would highly recommend Zach and the Stello Home Real Estate Team to handle your business needs! Thank you Zach!!

Nick Molthen

Zach and his team were a pleasure to work with from day 1! Being first time home buyers and on a tight deadline due to the end of our rental lease, we were a bit stressed to say the least. From our first interaction, Zach was knowledgeable and made each step easy to understand. Buying a home is a lot of work, but having Zach as an advisor through the process made everything so much easier. We highly recommend Zach for any real estate needs!

I've worked with Zach and his team for the purchase of two homes and now the sale of one home. Each time he came prepared and ready to execute. He did a great job educating and working with us so that we understood and were comfortable with everything that was going on. I couldn't recommend a service higher - I wouldn't use any other realtor in the NOVA area.

Lauren Phillips

My husband and I were first time homebuyers who didn’t know much about home buying. Working with Zach Costello allowed us to comfortably navigate the process to getting the keys to our first home! All we can say is that Zach is a consummate professional who consistently went the extra mile to make our initial home buying experience smooth and successful - over a period of several months of house hunting in the notoriously competitive northern Virginia market. His excellent attitude and work ethic were evident throughout the process. He was always responsive via call, email, or text message and worked quickly. We highly recommend him!

Zach was introduced to us through a friend and he absolutely knocked it out of the park. Within a day he helped us get prequalified and showed us the property, which had a short deadline to review offers. As first-time home buyers, we were very new to the entire process, but Zach’s knowledge of the market and professionalism left us at ease. He was available via phone and text with all our questions (there were a lot) at all hours. He was thorough, but simple in explaining every step/option that we had and made the process of buying our first home a blast! He helped us present the best offer possible and won in a very competitive situation. His dedication and service didn’t stop there, though! Zach has continued to be a great resource after closing and his knowledge and trustworthy resources have been a huge help not only in securing a great house, but also in making it a home! Thank you for everything!

Zach and team did an excellent job selling our house in an off season. He defin knows the market, dedicated a lot of off hours time to my needs, and really goes to bat for you when the other side tries to make things complicated. Highly recommended!

Zach is a wonderful real estate agent. From negotiating, home inspection, financing, he made the housing buying very smoothly. He has great knowledge on the communities of northern Virginia. It was a great pleasure to have him as our realtor.

Zach helped me find my first apartment to rent. I gave him the area I wanted to live and my price range and he gave me so many options to choose from with all the things I said I wanted! The process was so smooth and easy, I can't recommend Zach enough. He's personable, knowledgeable, and genuinely cares about finding a home right for you!

When I arrived VA for my new job, I had lots of things happening around, one of those was only finding a house for my family. I wasn't even sure that I can quickly find a rental place, given the fact that I had factors needed to be met for my living place, such as good school for my kids. With what Zach could do for me out from his professional experiences, and very much exceptional good understanding of the market and the local sales, I could have my nice house purchased, in such timely manner and with no hassle that I could do all other important tasks that I had at a same time. I do recommend Zach to anyone who wants an excellent experience for buying/renting her dream house.

Being a person not familiar with the Northern Virginian market since I grew up out of town, I was nervous to start looking for housing to own. I knew I had to rely a lot on the knowledge of my realtor. From the first meeting, I knew Zach was a person I could trust. Not only is he a great realtor and makes the process a breeze, he is a good person and helps you understand everything with real estate and what to look for. I would recommend Zach over and over..and cannot wait to work with him again one day.

Zach represented me as my agent during the home buying process. I was a first time home buyer and generally had no clue what I was doing. I actually began discussing the home buying process with Zach literally years before he began officially assisting me as his client. He was always there to answer any questions I had and was knowledgeable about all areas of the process. He is versatile in that he can offer big picture advice which really helped, but also was very good during the search/offer/settlement process with some of the specific recommendations and moves he made as I got closer to closing. Zach’s level-headed demeanor, professionalism, and character really helped make the process easy for me and I appreciated that. Just an example of Zach’s dedication- his wife was essentially in labor during my closing window and Zach still managed to come up with the goods for me! Can’t recommend him and Stello Homes enough.

Beginning the process of purchasing our first home was absolutely terrifying until we had Zach there to guide us. Having his expertise, professionalism, and personality was an absolute relief and comfort to us. Where we lacked knowledge, Zach covered our bases. When we were unsure, Zach provided the perfect advice. When we were stressed, he made us smile. We never would have found our perfect home without him! Zach, if you’re reading this, you are the BEST and we love you!

There are not enough good things to say about the experience we had with Zach Costello. From early on in the home buying process, when we were not even seriously looking, Zach was checking in with us to determine if our needs had changed, update us on any new prospects that he thought would be a good fit, and answer questions related to homes, finances, and everything else under the sun.

Zach's level of knowledge and professional yet personable demeanor made him an amazing choice to take us house to house, looking for any possible defect that he felt would be either a dealbreaker or a possible negotiation point.

Once we wanted to pull the trigger on a house, Zach worked very hard (on a Sunday!) to help us put in an offer, which was accepted within 24 hours. Even after acceptance of our offer, Zach was always around to walk us through the closing process and helped answer and alleviate any concerns we had, including helping negotiate the buying of some of additional items outside of the selling price for the house.

There are really not enough good things I can say about the work he did, the professionalism he did it with, and how likely I am to recommend him to anyone needing a great agent.

I have bought and sold multiple homes in different states, and I have worked with multiple realtors with no problem whatsoever. Zach Costello is clearly the worst realtor I have ever met.

Zach is such a self-important realtor that he has kept bossing around during the closing as if it is his show time. He would have ruined the deal if his client had not grab him out of the conference room.

Besides his attitude problem, Zach is not experienced and he has repeatedly delayed the communization between his client and the other party.

Zach was incredibly responsive throughout the entire process and provided insight that gave us confidence in our decision making. Zach prides himself on serving his clients; a level of dedication that sets him apart from his peers. When we ran into obstacles along the way, he took immediate action to resolve them with little to no effort from us as the buyers. I would recommend Zach to anyone who is looking for a trusted advisor within the real estate industry, no matter what stage they are in the process. I started talking to Zach months before we were serious about buying a house and he offered guidance and support with nothing expected in return.

Zach helped us buy our first home, and we couldn't recommend him highly enough. Because home-buying was new to us, we had a lot of questions that Zach was able answer promptly and knowledgeably. When we found the right house for us, he immediately provided his insight on the right kind of offer to ensure we didn't lose out on our dream home. Because of his quick action and knowledge of the market in our area, we landed our new home at an exceptional price and couldn't be happier. Zach is thoughtful, responsive, and made the home buying process the way it should be- perfectly painless, rewarding and exciting. Thank you, Zach!
