Why Thornton Homes Need a Different Approach
Original Thornton south of 104th Ave (1953–1970s) is compact ranches and bi-levels with 4–6 inches of settled attic insulation and uninsulated basement walls. North Thornton (Hunters Glen, Heritage Todd Creek, Thorncreek, 1995–2020s) is two-story production housing on open prairie — code-minimum attics, leaky can lights and bonus rooms that never hold temperature.
Thornton sits on open plains with no foothill shelter, so north- and west-facing homes take constant winter wind; attic air sealing before top-up is where the savings are. Xcel Energy rebates apply.

What Thornton Homeowners Say
★★★★★
Great service! A fair quote from a trustworthy company. They did a good job with the sealing and installing insulation. They missed boxing out a water heater pipe during initial install and as soon as I contacted them about it came out to fix it no charge. Left a clean home after their work.

Frequently Asked Questions
Do you serve all of Thornton?
Yes — every Thornton neighborhood, including Eastlake, Hunters Glen, Heritage Todd Creek and Thorncreek. Our crews come from Denver, 20–25 minutes north via I-25 or I-76, so scheduling is the same as a Denver job.
How much does attic insulation cost in Thornton?
It depends on attic size, existing depth and how much air sealing is needed. We measure on site and give a written price during the free evaluation — no phone guesses, no surprise line items.
Do I have to remove the old insulation first?
Only if it is wet, moldy, rodent-contaminated or so compacted it is doing nothing. Otherwise we air-seal and blow new insulation on top. We tell you which applies in the evaluation.
Can I get a rebate?
Xcel Energy customers may qualify for insulation and air-sealing rebates on qualifying upgrades; we show the rebate-eligible items on your estimate.
How long does the job take?
Most attic, crawl space and removal jobs are finished in one day. Whole-house projects take two to three days.
