From a failed insulated glass unit to a complete home upgrade, Apex helps you choose the right window solution for your DFW home.
If your frames are still in good condition, we can replace only the failed glass unit—not the whole window—to restore clarity and insulation while helping you avoid a full replacement.
When it's time for a complete upgrade, Apex Windows replaces every window in your home with modern, energy-efficient double-pane vinyl windows — installed in just one to two days.
Most jobs are completed in a single visit. Here's our simple 3-step process.
We inspect your windows, identify the issue, and provide a transparent quote — no hidden fees, no pressure.
Our licensed technicians replace only the insulated glass unit, keeping your existing frames. Most windows done in under an hour.
Enjoy restored clarity, improved energy efficiency, and peace of mind with our 10-year warranty on all work.
When your double-pane windows develop fog or condensation between the panes, the seal has failed. But the frame, hardware, and structure are usually still perfectly good.
See the two key stages of your project—from a careful measurement visit to a clean, professional installation.
See how our team measures your windows carefully before your custom glass is made.
Your technician texts when they are on the way, introduces themselves at the measurement visit, and reviews the window concerns with you. Most visits take 15 minutes to an hour. Apex then provides a detailed quote the same day or the following morning, and sends an installation-scheduling link after approval.
See what installation day looks like, from protecting your home to the final clean-up.
Your installer texts when the crew is on the way, walks you through the plan, and answers questions. The team uses shoe covers, protects areas around the windows, works carefully around exterior landscaping, removes and disposes of old glass, and completes a final walkthrough with a statement of completion or any needed follow-up list.

"I was quoted $6,000 for full window replacement by another company. Apex replaced just the glass for a fraction of that cost. Same result — crystal clear windows! Can't recommend enough."

Fast, professional, and the results are perfect. I wish I'd called sooner — I put it off for years thinking it would cost a fortune.
My energy bill has already gone down since they replaced the glass. They were here the next day and the whole job was done in under an hour.
Professional and respectful — they kept me informed every step of the way. Finally see clearly again and saved thousands versus a full window replacement.
