Long Windows testimonials

Nothing means more to us than the words of our customers. We wanted to share a few of their comments with you.

“Your technicians assigned to install my windows were utmost professionals. They arrived, told me what they were going to do and how long the task would take. They removed the windows. Installation went like clockwork; cleanup and demonstration was an education in efficiency. Hats off to a team of true professionals. I would recommend Long Windows to all my friends who are considering window replacement.”
– D. Bender, Gaithersburg, MD

“The new windows are beautiful. So much easier to open and close! The clean up was just remarkable. I’m kind of particular about the yard, and I was happy to see that I didn’t have to talk to them about, “Oh you missed this piece or you missed that piece.” They just did a remarkable job. I would recommend Long Windows to anybody.  It was a feeling of family and that was important to me. If I have a problem down the road, I want to go back to someone I feel comfortable with.”
– J. Johnson, Washington, D.C.

“I would definitely recommend Long Fence and Home for windows … they did a phenomenal job. Their product — the Heat Mirror product — is phenomenal.”
– Mrs. Lucy, Fairfax Station, VA
