Great to work with from start to finish. Reasonable prices & quick install. Would recommend to anyone looking to get their windows replaced. Thanks again!

Right from the beginning of picking the door to the clean up after installation these people are amazing. They were a pleasure to work with very helpful and answer every question. I would highly recommend Expert Windows and Doors.

A while ago I had a small but costly job done by this company. 18 months later it turned out I needed a roof. When I contacted Mark directly he said to me and I quote"house is old, roof will cost you a lot, best you slap a for sale sign up on the lawn and call it a day". This is my home!!! I don't appreciate the judgment and insults. Maybe he has a better place to live but how dare you?! I got a new roof from a better company and glad Mark didn't get my money (at least not the roof money, only the nearly 2K he charged me for a small job less than 2 years prior).

Worked with Mark and his team this past month. Had new windows, siding, soffits and gutters installed. My house looks like it is brand new. All of the workers were great, professional, friendly and cleaned up at the end of each day. The craftsmanship of the trim around my windows and doors inside and out is amazing. I can’t be happier with the work completed and would definitely recommend to anyone.

Mark and his team were excellent! Great communication and answered all our questions and updated us with progress throughout the roof repair. Highly recommend.

Our experience with Expert was great. Mark responded quickly to provide an estimate and outline the project. The crew that did the siding were friendly, very capable and did an excellent job. We are really pleased with the results and would highly recommend Expert! We have received many compliments from friends and neighbours about the new look of our home.

Mark and team went the extra mile to meet our needs, job done timely and looks great. Would highly recommend!

Mark and his team are great!!! They were quick to respond to an estimate request and completed the work quickly after we decided to move forward. I have had many other contractors delay, not respond, chase down, etc to get things done but not Expert Windows Doors Roofing & Siding. I will definitely reach out to them for future updates. They are FANTASTIC!

I can’t recommend Expert Windows Doors Roofing & Siding enough! Mark, the owner, took the time to walk me through all my options and provided knowledgable insights that helped make informed decisions. The installation team was courteous, efficient, and left the site clean every day. Highly recommend their service.

Mark and his team are professional and efficient. I had a leaking roof, contacted Mark and within 24 hours he responded and someone from his team was on site to fix the issue! Very reliable and great company to work with. I would highly recommend Expert Windows and Doors.

Expert Roofing came out on time Monday to complete a small roofing job with modification. They were professional & got the job done to my satisfaction quickly. They had to match shingles to 10 year old existing roof & did so flawlessly. Would definitely recommend Expert Roofing.

We had Expert come back again this year to complete our multi year project which included replacement of 3 windows and vinyl siding. The 2 gentlemen arrived on time and completed the job to our satisfaction. Their work ethic goes above and beyond!

Mark the owner came out soon after calling him for an estimate; my mother's home had water leaking through the window and the siding. The work was done in a timely fashion and completed in 1 day to replace the window, remove the siding on the upper & lower level.
Mark kept me updated on the work, sending me photos of the progress, before & after photos while we were on holiday.
Thank you Mark for getting this done quickly and efficiently with a fair price tag.
I highly recommend and trust Mark and his team!

You were highly recommended by friends and family, I'm impressed, and satisfied! I will recommend you to people I know.
E-payment to follow!

I used Mark to replace my eavestroughs, install new eavestrough screens, install new exterior garage door, replace window and cap all existing windows on my work shop as well as removing antenna on my roof and replacing shingles.
The timing that he mentioned for the work completion was spot on. His crew does excellent work and the clean up was perfect.
I highly recommend Mark and his team to manage your projects.

I absolutely love the transformation of my house after having Expert install my new siding. Mark was great to work with and his crew was top notch. I definitely recommend this company!

I've used Mark'services for a few years now, not only he offers quality work, quick response and solid ethics, but also is Johnny on the spot and on time! It is very hard to find all these qualities in one company these days, wish Mark and company great success!

This is the 3rd time Ive used Mark and the team. This time around I had 4 windows replaced. Expert Exteriors is a top notch team and I will use them again.

Not the first time I’ve used their services. These gentlemen know what they’re doing, they’re friendly and professional and they clean up. Thank you

Mark and his team were professional and detailed from start to finish. The team did a wonderful job installing the Sun Shades and kept us informed with every detail. Thank you again, I highly recommend Expert Windows & Doors.

We had an excellent experience with Expert Exteriors. Great communication and the on-site crew took the time to explain the process, then proceeded to do expert work. If they were this professional with a repair job, I look forward to contacting them for our next larger install project. Absolutely recommended.

Great experience. No hiccups. Excellent customer focused team. From the time I asked for quote to install was under a week. Took Marks team under two hours to rip down and install our Eaves Trough and downspouts. Thanks EXPERT for the painless experience. Lol

Great experience having our homes front window replaced by Expert. Mark and his team made the entire process painless, from initial consult to go over over options, providing us a fair quote with no high pressure sales pitch, to delivering a great product with skilled installers who did a beautiful job. Would not hesitate to call Expert again!

Very happy with the whole experience from start to finish. Fair price, workers were very polite, did a good job and cleaned up after themselves before leaving.

Extremely happy with the service provided - right from the initial visit for the estimate to the communication to the installation. Great family run company. The guys that came out to do the installation were very knowledgable, friendly, competent and communicative. They did a great job, hard workers. Price was reasonable and quality great. Highly recommend.

Excellent quality, fair prices. Installation was professionally done by excellent, well trained, knowledgeable guys. Very respectful and friendly crew. Our first but not our last purchase with Expert Windows and Doors. Highly recommended.

Had my old patio door replaced today and it looks great! Experts was a pleasure to deal with. Matt and Zak were very professional and did a great job!

Had siding, windows & doors installed recently and very happy with the result! Friendly, responsive service & everything looks great. (Side note: the guys put my fence back up after a bad wind storm knocked part of it down...not necessary, but I'm very grateful for the help! Lol) Highly recommend

From start to finish, the process was smooth and professional. We are very pleased with the end result. Who knew quality windows and doors could bring such great light to our space!? We love them. Price was right, and project manager Mark DiPonio was kind, responsive, and all-around pleasant to deal with. We have no hesitation recommending!

Call the Experts, you’ll be glad you did!!!! Mark was great to deal with and made the process easy, turn around time from purchase to install was quicker than most if not all other window companies in Windsor/Essex. Expert is a name they live up to as they have very knowledgeable and efficient installation guys in Matt and Zack.

Having used the services of Mark and his crew on a dozen or so projects over the last few years, I can honestly say that I have yet to find anyone to match the quality, price, and professionalism he and his crew have. I don't say this lightly. My own crew has seen many subcontractors come through our jobsites. Experts is by far one of their favorites. There is no one else I recommend! Call today!

I had Expert Windows Roofing & Siding in 2020 do my siding and upper window replacements. I was so happy with their pricing, workmanship and quality of products I ordered again in 2021. This year was a front door, storm door and picture window. I am extremely happy and highly recommend this company.

Joe was honest and fair with his pricing. The installers (Mark and Zach) were on time, courteous, professional and personable. Their work was precise, they explained every step of the process and took their time doing the installation. They cleaned up inside and outside the house. I highly recommend Joe, Marc and Zack to anyone.

I would HIGHLY recommend Expert Windows and Doors! We just had 7 windows installed in our home and couldn’t be happier with the end result! The Windows are amazing, the quality of the work impeccable and the customer service was great! Purchasing windows can be a bit overwhelming and Mark made sure We were well informed from beginning to end. We had multiple quotes and Expert was extremely competitive! The crew that installed the windows in 1 day were professional, Competent and clean! I HIGHLY recommend Expert Windows. We will be using Expert for again when we replace the rest of our windows and roof!

First of all, Mark is an excellent project manager, super quick replies to all emails, quotes were received the same day as our meetings to discuss the job, very polite and professional. Job was started the same day my deposit was given and completed early the very next day. Very fair price. Everything was left clean and tidy, job was very well done, looks great. The Installer I spoke with in the morning was very polite and friendly, very professional, did a great job. Looking forward to beginning the next project. Have already recommended to my friends.

We had new windows and siding installed last year. Still looks brand new. Patrick did a great job using quality materials and craftsmanship. Would definitely recommend the Experts

The crew did an excellent job on my front door installation(left the place nice and clean)..Mark gave us the best quote and was very good with communication.Overall, very pleased with the entire process and i recommend them 100%.

Mark and his company did a great job on my roof repair. The replacement shingles matched perfectly. Tim did a very good doing the work involved. Thanks for a great job.

An excellent job. The installation looks perfect. The workmen were polite and asked for our preferences. The yard was neat and tidy when they finished. We have already had compliments from neighbors and referrals. The final bill was exactly what was quoted. Thanks for a great job.

The crew did a great job replacing my eaves and fascia. Very happy with the quality of work and easy to do deal with Mark.

Thank you Mark and crew for your exceptional work in installing our eaves troughs. The work was done on time, the price was right, and the end result is perfection! The guys on the job worked professionally and were very personable. This company is highly recommended.

Company was great. Mark was nice with quoting and Email response (communication) was fantastic. They installed the windows on Monday. Left no garbage behind, no marks on the walls or outside at all. I don't need to re-paint anything. I would use again and recommend.

This is an excellent local company.just had a new patio door installed.workmanship was great and good pricing.thank you mark and your entire team

Great job during difficult times of COVID. Thank you so much for a perfect instal and amazing communications. I will be using Expert for all my renos in the Windsor area.

Very quick response to my initial request for an estimate. Came out and provided thorough quote which came in lower than a couple of other companies. Crew that came out were professional, quick and left no mess. Made me feel that my business was important even though it wasn't a large job (partial Eavestrough). Thank you.

WOW WOW is all i can say I could not have pictured the whole thing turning out as stunning as it is.
We are very pleased with the work done by Expert. We were quoted on all the work, the whole house; doors, windows, siding, soffit, fascia and eavestroughs. We even got a new custom size door for the back basement entrance which required some tricky cementing as well. They are truly amazing an amazing team. All work was done to a very high standard as they went above and beyond to make sure all the little things were addressed and the outcome is stunning! The team was very polite, professional and just nice bunch of guys to have hanging around your house. The neighbours have also commented on the amazing job that has been done. Expert might not be the least expensive depending on who you call but the results are certainly worth every penny. We actually got three quotes and they were the lowest but their standards are HIGH! I even spoke to a neighbour who did his house himself and said they prices were quite reasonable. Would definitely highly recommend.

I was looking for some quotes and I was given an appointment for consultation for the next day! Expert was very friendly honest and knowledgeable! Definitely not trying to push a sale but given options even if it would not benefit his business! WOULD HIGHLY RECOMMEND!!!

Excellent! Showed up on time for the estimate and for the windows. Polite, explained everything to me when I asked, would highly recommend.

I live in a 4 Plex and the guys did new roof siding and windows and they were by far the MOST polite and kind workers I have ever experienced. They were very clean and accomadating to me and my dog going outside 400 times a day lol.

Mark and his team did an awesome job installing new eves troughs. They look great. Very professional team. They cleaned up and took away all of the old material. Much appreciated. Thank you!!

Wow... Fantastic windows and fantastic sales and installation crew... They went above and beyond ...thanks shout out too Matt, Zack and owner Joe .. great job!!

Mark and his team did a fantastic job, everyone was professional and experienced. The siding job Expert Exterior did for my house is beautiful. Mark also did some trouble shooting regarding a leaking problem between the balcony and my house, gave me a few options to fix the problem, and Expert Exterior fixed the problem; no more leaking into the wall!
I strongly recommend Expert to others and will return to them again when I need them.

Me and my husband was in a rushed to find a sidings Installer for the back of our house ,Coz we needed to get it fix for the house insurance and the insurance company only gave us 9 days to get it fixed if we don't get it done on time we get penalized . But me and my husband we’re glad coz we found this company Expert windows doors roofings and sidings and Mark Di Ponio the owner and his staff are the 1 that did the Job. There very polite and very friendly and They absolutely did a nice job on our sidings for a very reasonable price and they were done 2 days early before the due date..

My wife and I have had a fantastic experience with Expert. Mark was an effective communicator, provided expert insight and suggestions and furthermore is extremely professional. We are happy we trusted Mark to install our front door!

Recently got our roof done, fast turn around. Very polite staff and friendly sales team! Will pass your info to my brother as he needs a roof soon also. Thanks again!

Mark diponio came to my home to give me a quote on 3 doors I wanted replaced. As we are finishing up he starts staring out my window at his truck like he thinks someone is stealing it. Starts acting really weird. So I walk him to the door, he tells me he will email me the quote. And I never hear from him again. Honestly not to disappointed. The guy is creepy.
