"I love my new Windows! Gary, window consultant gave a great in home consultation, did demos with actual windows and answered all questions and was thorough. Months later windows are finally installed and they are beautiful and changed the look of my entire house. I highly recommend Brothers if you need new windows and I’m so glad I found them in the Angi app. I had a number of different sub contractors in my house through Lowe’s and other companies I found through google that were quoting me insanely high prices after walking through my house , spending 3 minutes before they gave me my insane estimate. Brothers does windows only, has been in business for 30 years (my window installer, Wes has been with the company for 25 years, so that speaks volumes) so they know what they’re doing and got the windows installed so quickly, they were done in a day. If I ever need new windows again, I’d go with them again and will recommend to any friends and neighbors as well."

"The job went smoothly, replacing the rollers in two large glass sliding doors. Prior to the job, they were almost impossible to move, now they roll in the track like new. I was a bit surprised by the price, however, the entire job took under three hours and four new rollers were installed, yet the price was almost $1,000, which seems high."
