Homes in Denton

What we see in Denton homes.

Denton has early 1900s homes near the Square and the universities, mid-century neighborhoods around them, and newer subdivisions to the south and east.

Original wood and early aluminum windows

Many of Denton's older homes still have single-pane wood or aluminum windows that rattle, sweat and let summer heat straight in. Replacements can keep the look while adding Low-E, argon-filled glass.

Thin or missing attic insulation

Homes built before modern energy codes often have only a few inches of insulation, or bare spots where it has been disturbed. Bringing it up to today's recommended depth is one of the fastest comfort upgrades.

Doors that have shifted with the house

Decades of North Texas clay soil movement can leave entry doors sticking, dragging or leaking light around the frame. A new pre-hung door is set square and sealed.

Questions

Denton window, door & insulation FAQs.

Do I need a permit to replace windows in Denton?
Requirements depend on the scope of the work, for example whether the opening size changes. We check with the City of Denton for every project and pull any permit that's required as part of the job.
What if my Denton home is in a historic district?
Homes in Denton's historic districts can need city approval for exterior changes, including replacement windows and doors. We check your address before we quote and help you choose windows and doors that fit the district's guidelines.
Do you work with Denton HOAs?
Yes. Many Denton neighborhoods have HOA rules on window color, grid patterns and front doors. We can provide product specs, colors and photos for your architectural review application before anything is ordered.
How much do replacement windows cost in Denton?
It depends on size, style and the line you choose. Our 8000 Series aluminum windows run about 20% more than our 5000 Series vinyl; our window cost estimator gives a broad range from photos of your house, and this guide breaks down DFW pricing.
How soon can you come out to Denton?
We schedule free in-home assessments across Denton County and the rest of the metroplex, usually within the week. Book a time online or call 469.340.4780.
Is financing available?
Yes, on projects of $2,500 or more, with terms of 1, 3, 5 or 10 years, subject to credit approval. Estimate a monthly payment.
How long does installation take?
Most window projects are installed in one to two days once the custom windows arrive; an entry door is usually a single day, and attic insulation is typically done in a few hours.
