Best window pros near Leesburg, 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."

"This company was thorough, professional and punctual. The gentlemen doing the work were friendly, explained everything in advance and did exactly what they said they would do - spotless windows, sills and screens, inside and out!! I would DEFINITELY recommend them for anyone's window cleaning needs!! A+++"

"How wonderful my most lovely windows are from Windows on Washington & their installation team was brilliant at keeping all my furnishings covered. They were on time, efficient & most polite. I highly recommend them."

"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."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"Jeremy did a great job with tinting our bathroom, kitchen and garage windows."

"Wow my windows look new"

"They rebuilt my broken window from the pieces, it saved me lots of money and grief, since new windows would not match the old ones."

"The team that performed the work were excellent. They took great care to protect my wood floors and were very neat. I decided to do more windows and I'm using them again."

"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!"
