How do I reach Longmont Colorado Insulation?
Phone: (720) 491-3309
Email: leads@longmontcoloradoinsulation.com
The form takes web inquiries around the clock; the phone is answered during business hours. Because your project is handled by an independent contractor, we can't promise exactly when they'll call once your details are routed — only that we don't waste your time.
No mailing address is published: this is a referral service without a storefront, so the form and the email above are how you reach us — and email is the paper trail if you ever need one.
What happens after I submit the form?
Your details go to one local retrofit insulation contractor — not a call-center list of ten. We may be compensated for that referral. The contractor contacts you directly to scope the work and quote it. See the privacy page for what we collect and share.

We've Got It. Here's What Happens Next.
We've got your info and are routing it to a local pro. When they call, here's what to look for in the quote you receive: (1) R-value target — the model energy code for Climate Zone 5 calls for R-49 to R-60 attic insulation; ask what your contractor is quoting to. (2) Air sealing scope — insulation alone does nothing if air leaks aren't sealed first, and Xcel requires a blower door test to rebate it. (3) Rebate handling — ask which programs your specific address qualifies for. Xcel and Efficiency Works are separate programs with separate paperwork, and not every address qualifies for both. (The federal IRA Section 25C tax credit ended December 31, 2025 — no federal insulation credit applies to 2026 work. Xcel Energy's insulation and air-sealing rebate remains active for its gas and electric customers. Longmont Power & Communications electric customers may separately qualify for an Efficiency Works rebate — check your bill to see which utility serves your address. Boulder County EnergySmart pays a third, income-qualified-only rebate as of January 1, 2026.) (4) Removal scope — older homes often need old insulation removed before new install.
