Best window and door contractors near Ashburn, VA

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"Eddie was highly knowledgeable and helpful after my kids broke my window during a winter storm. He replaced the glass in a challenging situation. I highly recommend him."

"I originally needed a three-panel window fixed since it was loose from the frame. About 10min after I submitted the request on Angi's, Gilberto called me and said he could stop by since he was in the area and at the end of his day. He was able to make a fix on the spot and addressed some dirt/uncleanliness in the window frame from the previous owner. I then asked if he could come out and clean all the windows/frames and his price and availability was more than reasonable. Gilberto and his team came out the next week and spent several hard hours cleaning. Just recently he returned with the window screens that needed repair and washing. His last service for us was spot caulking/sealing the exterior window frames where needed. I highly recommend Gilberto and his service. He was professional, prompt, great at communicating what servicing was needed or wasn't, and the work and price was top notch."

"First off my apologies for the delay in sending this review. I had a home project that I needed to have done. So I went to Home Advisor/Angies List for assistance. I was given the names of several contractors in my area to contact. Of those contractors I made to selection of NOVA Renew Construction LLC, Manager Bassel Alkassen. Mr. Alkassen came to our home on 2/11/23 to see the project and give a estimate for the repair of four windows, and a sliding glass door. He sent a written estimate on 2/12/23 and I did contact with him on 2/13/23 to confirm that I wanted him to do the job. Mr. Alkassen ordered four windows for me and returned on 2/15/23 to do the repair work. Throughout this entire process, Mr. Alkassen conducted himself in a very pleasant, respectful and professional manner. His prices for my job were very reasonable. The service that he performed for me was way above and beyond my expectation. I would highly recommend NOVA Renew Construction LLC to anyone needing these services. Thank You Nova Renew Construction and Thank you Angie/Home Advisor for the service you provided"

"I forgot the guy’s name that came to look at the job. He was nice and quick to estimate and explain and not into ‘selling’ services like 2 other companies did. Ordered the slider I wanted and installed it when it came in . I had decided to use a company that specializes in door and window installation instead of the previously used 2 big box garden/supply chains in the area. Very happy with the quality of the slider and the professional installation!"

"EXCELLENT, as usual!!!! I have used Unicorp previously in 2015 - windows, siding, gutters, soffits/fascia. In May 2023, I used them for front door and storm door replacement. They are responsive, professional, charge a very fair price for QUALITY products and workmanship."

"We have had NovaExteriors replace all our gutters, windows, sliding doors and front door over the last several years from the contractor grade products that the town house was built with. We have been very pleased with everything. They installed our steel front door about 10 years ago and we started to have issues with the deadbolt not aligning with the door jam and the rubber sweep wearing out over time. I contacted NovaExteriors, made my appointment and they arrived right on time and performed the needed maintenance that was required. The door is back to being perfect. Once again, we were very pleased with NovaExteriors, their prompt arrival and the quality of work. You can't go wrong with NovaExteriors."

"The transom window above my French doors had lost its seal. Devon arrived on time, took all the measurements, and put the order in to make the glass. Although he had a lot of trouble getting the old piece out because it wasn't installed properly, he took his time and made it look perfect. He's a very nice young man professional and courteous. I recommend them anytime!"

"Sometimes you find a contractor that is a professional but rarely can you call them a friend once the job is completed. Gary is that. He’s patient, listens and delivers on the project game plan. I hesitated to write this post because I don’t want him to get too busy lol but it’s best to share when you find a great contractor so others may benefit so here you go. Call Gary, but an allocate more than 10 minutes on the phone lol. And that’s a good thing. Pictures to follow."
