Colorado's climate is tough on homes. We make yours ready for it.
Boulder County homes face single-digit winter nights, big day-to-night swings, dry mountain air, and intense high-altitude sun. Insulation and air sealing are what keep a home comfortable and affordable through all of it — and doing them right, for this specific climate, is what we specialize in.
We install the full range — spray foam, blown-in, and batt — and we combine them the smart way: the right product in each part of your home, over a properly air-sealed envelope. The result is lower bills, steadier temperatures, and a home that finally feels right in every season.
And because Boulder is serious about energy, we help you take advantage of it — building to cold-climate R-value targets, meeting local energy code, and capturing the Xcel Energy rebates that bring the cost down.

Boulder insulation FAQs
Boulder County sits in a cold climate zone where recommended attic insulation is typically R-49 to R-60. Many existing homes fall well short. Bringing your attic up to target is usually the single highest-return efficiency upgrade available, with a payback measured in just a few years of lower bills.
It depends on the space. Spray foam offers the highest R-value per inch plus an air seal (great for basements, rim joists, and vaulted ceilings). Blown-in is fast and cost-effective for attics. Batts are reliable and economical in open framing. The best homes use the right product in each spot — we design the combination for you.
Yes. Insulation and air-sealing upgrades frequently qualify for Xcel Energy rebates, and additional Boulder County and federal incentives are often available. We assess your home, design the project to qualify for as much as possible, and help with the documentation and paperwork.
We serve Boulder and all of Boulder County — including Longmont, Louisville, Lafayette, Superior, Niwot, and Nederland. If you're in the area and not sure, just give us a call.
It varies by service, home size, and R-value target. A straightforward attic top-up is very cost-effective, while spray foam or whole-home projects cost more. We provide a clear, itemized free quote after assessing your home — and factor in the rebates you qualify for.
Almost always. Air leaks can waste as much energy as a window left open all year. Air sealing is typically the highest-ROI efficiency work you can do, and it makes any insulation you add afterward perform to its full rating. We usually recommend it as the first step.
