Best glaziers near Herndon, VA

"I must admit, I had Unicorp replace all of the windows in our home with new vinyl energy efficient windows 10 or more years ago. Their installers were excellent. The quality of their windows were excellent. The proof in the pudding is that after 8 years not one of my windows has an air leak. Not one has leaked water. Not one window has had the vinyl or track break. In short, nothing has happened. Now that's a quality window! We also purchased a custom sliding glass door (in the kitchen to the deck) from Unicorp that to this day I believe is the best door in my entire home. That door is opened and closed constantly to let the cats in and out. If you own cats, you will understand how often that door is opened and closed on a daily basis. We have not had a single hiccup ever with that door. And in the winter, I sit right behind the door and no matter how cold or windy it is, I never feel a thing at the kitchen table. Because Unicorp did such a great job in replacing the windows in our home, my wife insisted that we use Unicorp to replace the roof last week. If you see my review on the roof, they did a 5 star job."

"I absolutely love the whole processes. Unlike other big names, Mr. Scott didn’t push at all. No sale pitch and other hidden fees. Everything was transparent. When I requested a estimate, he contacted me that evening and stopped by in two days. He spent less than 20 min to measure windows sizes roughly. That was it! He sent me a quote next day and the price was really competitive. We communicated via emails for several questions and he answered them all quickly. He gave me enough time to make the final decision. Like I mentioned earlier, no pressure. Once I made the decision and signed contract, the actual contractor came by to measure everything accurately. After waiting several months (it took longer than I expected because of the pandemic), windows and sliding door finally arrived and set up the installation date. The installation contractor, Mr. Park’s team, is absolutely great. They were professional and their workmanship is beyond expectation. Several occasions, his team confronted some issues and they explained them clearly and found ways to get jobs done, In less than two days, 11 windows and 1 sliding door were finally installed. They all look beautiful and I am more than satisfied, I will absolutely hire them again for any future projects!"

"Super reliable and honest in Gilberto's approach which I loved the most! I would definitely go back to Glass and Windows Solutions again for my future needs."

"Super quick and efficient. I broke the glass I On my window and within 2 minutes of filling out the online page with my info I received a phone call. They showed up less than 2 hours later for my estimate and 48 hours later my glass was done and installed. The installer was very nice and help. Would recommend. I did not get multiple estimates so I don't know how the price compares but well worth using this company."

"Fantastic experience with JS Jackson! They did 2 projects for us - window replacement (6 windows for a townhouse) and cut and install new kitchen window. The leads on each project were very knowledgeable and great at explaining the process, answering questions, and advising on the best products for quality, budget, design, and function. Workers were friendly and professional. The office staff is very responsive at handling scheduling, permits, invoices, etc. It’s been several months and the windows are clearly properly installed, well-sealed, no leakage, and outside framing looks flawless. Would hire again!"

"Clifton Contracting made the whole process so easy from planning to completion. We are thrilled with the window and the complete change in our basement. We chose a larger Anderson window and an upgraded Rockwell window well. No other estimates could match them."

"Purchasing my new windows was a very pleasant experience from sales to installation. Roland and Tiffany handled the transaction in a very professional manner and I was very impressed that they came by my house during the installation to make sure everything was going well. I am very satisfied with my new windows, they look great. I would strongly recommend Star Improvements for their quality service and competitive pricing."

"A. R. Glass did a fantastic job. Instead of having to replace my windows, they were able to come in and replace the glass for considerable savings. I would definitely have them come again. In fact, I had them come for a second job already."

"I had two old sliding glass doors where the wood around the glass was rotting. The needed to be replaced. I went to the Germantown Home Show and got three companies to come out and do an estimate. Presidential was easily the best choice of the three. The doors got ordered and a month or so later they arrived and were installed the next day. The crew from Presidential was professional and courteous. The door installation went quick and they cleaned up like they weren't even there. I am very pleased with my new doors."
