Why Keller Homes Are Different
The bulk of homes went up between the late 1980s and early 2010s, mostly brick veneer and stone facades with large vented attics. Builders in that period did the minimum the code asked for, which means fiberglass batts now compressed under years of foot traffic, blown-in cellulose settled below the top of the ceiling joists, and attic floors that leak conditioned air into the roofline. In master-planned communities like Hidden Lakes and Marshall Ridge, we regularly open attics and find radiant barrier decking from the 2000s that’s been buried under later blow-in jobs. Once that foil is covered, it stops reflecting heat, and the attic simply bakes.
Summers here regularly pass 95°F, and that heat loads the attic first. A poorly insulated attic pushes that heat down into bedrooms and living space, making the air conditioner run longer just to hold 74°F. Winter is the quiet problem: Keller gets enough freezing nights that a warm attic against a cold roofline can frost, and when warm air leaks through gaps in the ceiling, it can thaw and refreeze at the eaves. Proper insulation with air sealing addresses both directions. It’s a year-round comfort issue in this climate, not a seasonal one.
Our Main Keller Services
The two calls we take most from Keller homeowners are for Attic Insulation in Keller and Spray Foam Insulation in Keller. Each has its own dedicated page with full pricing and process details.
Attic Insulation in Keller
Most Keller attics need either a full removal of old, compressed material or a top-up of blown insulation to reach the R-value that makes sense for this climate. We inspect the existing depth, check for air leaks around can lights, plumbing penetrations, and the attic hatch, then give you a written price before any work starts. Hidden Lakes homes with buried radiant barrier often benefit from removal first, because topping up over compromised material doesn’t solve the problem underneath. Learn more on our Attic Insulation in Keller page.
Spray Foam Insulation in Keller
Spray foam in Keller works differently: it seals and insulates in one pass. That matters in two-story homes where the upstairs ceiling is the attic floor and the temperature difference between floors is noticeable. Closed-cell foam also adds structural stiffness, which some Keller homeowners value in older homes with large roof spans. We’ll walk you through open-cell versus closed-cell options, what works best for your roofline, and the exact price before scheduling. Learn more on our Spray Foam Insulation in Keller page.

What Keller Customers Say
"Our bedrooms were always cold. They added insulation and air sealed the attic, and were meticulous about cleanup, you'd never know they'd been in the attic. So much cozier now."
- Donna Petrie"Good insulation work and a tidy crew. Scheduling took a couple weeks since they were booked, but once here they were quick, clean, and careful of the house. Upstairs is comfortable now."
- Marla Denton"Attic insulation. The crew laid down protection from the front door to the attic hatch and vacuumed up every bit of the old material. House holds its warmth now and there was zero mess."
