Most Trusted Window Replacement Company In Houston
"Absolute perfection! Their pricing was nearly half the cost of the competition for the same exact window and the installation process was a dream. They were here for maybe 5 hours on installation day and finished the entire house. When they left, the house was impeccably clean, like nobody had done any work that day. I was even impressed with the silicone finish against the brick on the exterior and the interior was perfect. They had to cut Sheetrock and window sills and I didn’t have to clean at all when they left. I didn’t receive compensation for this review, I’m just that happy with our new windows! I really didn’t think I would be this excited about windows but so so so glad our garbage single pane windows are gone and I couldn’t recommend Longhorn enough! Now I need to paint the gutters to match 😻"

"Happy customer! I was pretty sold on Longhorn by seeing my neighbors windows during a backyard function. Upon calling for apt, Norma answered the phone and was so congenial, I eagerly awaited apt day. Eli arrived and sealed the deal. He is the epitomy of a business owner. Service installers were on time, worked seamlessly together and when they left you would never have known they were here. No glass shards or trampled shrubs. Just beautiful new windows which bring me compliments daily! I highly recommend Longhorn Windows."

"Our 25 year old single pane windows were energy inefficient and dripping on the wood window sills year round. Eli and his crew installed new energy efficient windows and we are very happy with them. It makes our house look brand new and it was a pleasure working with Longhorn. We highly recommend them."
