I am absolutely thrilled to write this review for Designer! From start to finish, Fredy and his team delivered an outstanding experience, culminating in the flawless installation of a brand new sliding door in my basement.

Choosing a company for home improvements can be daunting in Northern VA, but Fredy made the entire process seamless and stress-free. Their professionalism was evident from the initial consultation through to the final touches. The installers were incredibly skilled, efficient, and clearly took immense pride in their work. They paid meticulous attention to every detail, ensuring the door was perfectly aligned, sealed, and operated smoothly.

The quality of the installation is truly top-notch. There's not a single imperfection, and the new custom door has completely transformed the look and functionality of my basement. They also did an excellent job with cleanup, leaving the area spotless.

It's rare to find a company that combines such high-quality workmanship with exceptional customer service + honest pricing. If you're looking for a windows and siding company that delivers on its promises and exceeds expectations, I wholeheartedly recommend Freddy and his company. You won't be disappointed!

Fredy and his crew were very responsible, and get all the jobs done quickly . Fredy managed his crew to make sure everything was done correctly and professionally. Fredy and his crew had done some work on my residence and rental place. They replaced the roof and windows on both houses. In addition they just finished installing siding and replaced Gutters on my house. Fredy and his crew takes pride on their work and make sure that customers happy with ordered materials and effort that they put on to their work. I’ve been Fredy customer for many years. That’s because I trust Fredy and his crew and knowing that they will do excellent work . I am a one happy customer and strongly would like recommend “Designer Windows and Siding” for your next home improvement. Fredy will good take care of you.

We had doors, a window and gable siding replaced. Fredy was hands down the best business owner to work with. He is responsive, accommodating, courteous and flexible. He had different crews specialized in each project, one for windows/doors and another for the siding. We had specific ideas and designs that we wanted. Fredy listened and was willing to accommodate and provide us with options. He was never trying to push products or ideas on us and we never felt pressured on anything. We loved the doors/windows crew. They were on time, respectful, friendly and they did a great job. There were a couple of hiccups with the siding, but Fredy came out every day and we came up with fixes. We've worked with numerous contractors across various specialties. There was always some sort of frustration or argument with each project because the crew cuts corners and/or the owner is unwilling to listen to what we wanted. Fredy is the only contractor/business owner who we feel truly wants to listen and make his clients happy. He is happy to work with you to get to a final project that you are happy with without getting defensive and letting pride get in the way. On top of that pricing was reasonable. He is not the cheapest but he is nowhere near the most expensive. Highly recommend Fredy and Designer Windows and Siding.

Designer Windows and Siding did great work on my home! Replaced all windows with a superior product and replaced the siding with an amazing cedar shake! Fredy provided exceptional support to my wife and I as we crafted just the right look for our house, and then executed our plan with amazing results. Fredy’s team were on time, friendly, and professional - all at a reasonable price. We highly recommend him and he will be our go-to guy on future projects. Thanks Fredy!

Fredy came recommended to me by friends and I hired him to do my windows at my condo in 2013. I then had him replace my front door in 2014, which made an incredible difference in my heating bill! And his guys were amazing and fixed some unexpected rotting wood as well. Today, Feb 2021, Fredy and his crew just replaced my sliding glass doors and back door in my new house. Fredy and his crew are impeccable. They do amazing work and Fredy’s quotes are always within range of expected but with much greater customer service. Also, Fredy will give you quotes and ideas and not try to upsell. He will work within your budget to get you the best possible. Highly recommend Fredy and his crew. I know I’ll definitely be using them again!

Fredy, the owner, and his crew are excellent to work with, professionals you can trust and rely on. I had 10 windows originally replaced with Fredy's windows with no installation or product issues whatsoever. Great value and exceptional service. I really like the new, modern type, double paned windows. Recently, there was damage to one of my windows from external sources; Fredy accurately troubleshot the problem and fixed it. It is such a blessing to work with a team I can trust!! Thanks Fredy, Lester, and crew!

The new front door I purchased through Designer Windows and Siding immensely improved the curb appeal of my home and greatly increased its resale value.
Fredy Burgos, the owner, clearly explained the benefits of the doors’ superior quality
I’m completely satisfied with my new door and would highly recommend Designer Windows and Siding to anyone.

We had the Front Door replaced at our first home in Centreville...Loved the quality of the door and the color! When we purchased our 2nd home in Manassas we also replaced the Front Door and added a storm door as well. Again the quality of the Doors and Color was as I expected, GREAT! The Storm Door allows us the option to use it with all glass or we can remove that and place the Screen on, love the two options. From the time we met with Fredy Burgos, the Sales Rep/Owner of the company and the installation, the service was very professional and in timely order. We didn't have to wait long for the door! The door was a perfect color match to our new shutters! We’ve received many compliments from our Neighbors. Our next big project will be window replacement and we will be calling on Designer Windows & Siding again for that service without a doubt!

Designer Windows & Siding replaced all of the windows in our home and switched out a set of French doors to a more secure sliding glass door. Fredy is extremely knowledgeable, professional, and friendly. From the consultation to the install, Fredy and his team did an exceptional job. The work was completed in one day and we’ve never had any problems with our new windows or door. I highly recommend DW&S as a go to for anything home related.

A terrific experience from start to finish getting my windows replaced. Fredy, the owner, went over the options in detail. No hard sell or upsell. The installation went perfectly. The crew was mindful of my home, worked hard, and left the space cleaner than they had found it! I overheard one of the crew calling down to my condo neighbor below to say he would be down later to sweep off any debris on her patio caused by the work—that’s going the extra mile. Fredy came by to see how the project was going which was another sign of excellent customer care. The crew discovered and alerted me to a sill affected by wood rot and spelled out what needed to be fixed so that the window could be installed properly. No hiding a problem just to get the job done quickly. I wouldn’t hesitate to recommend the quality work of Designer Windows & Siding.

Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
