Homes in Allen

What we see in Allen homes.

Allen grew from a small town to a large suburb mostly in the 1990s and 2000s, so many homes are 20 to 30 years old: the age when original windows, doors and attic insulation start to show it.

Builder-grade windows wearing out early

Many Allen homes were built with basic builder-grade vinyl windows. After 15 to 20 Texas summers, seals fail, frames warp and the glass lets in more heat than today's better Low-E packages.

Insulation at the code minimum

New-construction attics are usually insulated to the minimum required when the house was built. Adding depth now pays off in lower bills and a cooler upstairs, especially in two-story plans.

Doors facing big afternoon sun

Tall front doors and sidelites in newer plans take a beating from the west sun. An upgraded fiberglass door and glass package seals tighter and holds its finish.

Questions

Allen window, door & insulation FAQs.

Do I need a permit to replace windows in Allen?
Requirements depend on the scope of the work, for example whether the opening size changes. We check with the City of Allen for every project and pull any permit that's required as part of the job.
Do you work with Allen HOAs?
Yes. Many Allen 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 Allen?
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 Allen?
We schedule free in-home assessments across Collin 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.
