4.9 average • Google + BBB
“After years of leaky single-pane windows, our 1970s ranch finally feels modern. The crew was punctual, professional, and the difference in our August AC bill was nearly $100.”
Jennifer R.

“We got three quotes. Colin's wasn't the cheapest—but they were the only ones who actually measured every opening and explained the glass options. Worth every penny.”
David & Ana M.

“Our new front door is a showstopper. Neighbors keep asking who installed it. Project was done in a day and they cleaned up better than my own kids.”

Questions, answered
Real answers from real homeowners.
Don't see your question? Call us — we love nerdy window questions.
Window pricing depends on size, material, and glass package. Most North Texas homeowners invest between $650 and $1,400 per window installed. We provide an itemized written quote on every estimate—no surprises.
Most whole-home window replacements are completed in a single day. Larger custom projects may take two. We always confirm your timeline up front and clean every workspace before we leave.
Yes. Our customers report an average reduction of 25–30% on their cooling costs after upgrading to ENERGY STAR® windows with Low-E glass and argon fills—especially valuable in Texas summers.
We do. Qualified homeowners can take advantage of 0% interest plans, low-monthly-payment options, and senior/military discounts. Ask your consultant about current promotions.
Every installer on a Colin's Fenestration jobsite is a W-2 employee with full insurance and background checks. We don't subcontract installation—it's how we keep quality consistent.
All products carry the manufacturer's lifetime warranty, and we back our installation with a lifetime limited workmanship warranty for as long as you own the home.
