About us

Boulder's insulation specialists.

BoulderInsulation.com exists to do one thing exceptionally well: make Boulder County homes more comfortable and more efficient with the right insulation, installed the right way for our climate.

Insulation is one of the most impactful — and most commonly botched — improvements a home can get. An attic left at half the R-value it should be, insulation piled over unsealed leaks, batts stuffed carelessly around wiring: these mistakes quietly cost homeowners comfort and money every single season. We got into this trade to do it properly.

Built for the Front Range

Boulder County is a demanding place to keep a home comfortable. Winter nights drop into the single digits, the sun is intense at altitude, the air is dry, and the wind drives heat right out of a leaky house. Add some of the most progressive energy codes in the country, and it's clear why insulation here needs a specialist rather than a generalist.

That's the gap we fill. We insulate for Zone 5B reality — building attics to R-49 through R-60, sealing the envelope before adding R-value, and getting the ventilation and moisture details right so the whole system stays healthy. We install the full range of materials — spray foam, blown-in, and batt — and we combine them intelligently, putting the right product in each part of your home rather than defaulting to a single approach everywhere.

We also treat rebates as part of the job. Between Xcel Energy incentives, Boulder County programs, and federal energy tax credits, a well-planned project can cost far less than homeowners expect — but only if it's designed to qualify and documented properly. We handle that so you don't leave money on the table.

Above all, we believe in honest work. We'll tell you plainly whether your attic needs a full tear-out or just a top-up, whether spray foam is worth the premium in your case or whether blown-in will do the job for less. The goal is a home that's genuinely more comfortable and more efficient — and a homeowner who'd recommend us to a neighbor.

A whole-home approach

We don't sell products off a truck — we solve comfort and efficiency problems. That means we look at your home as a system, where insulation, air sealing, ventilation, and moisture control all work together. A beautifully insulated attic over an unsealed ceiling still leaks heat; a tight home without proper ventilation can trap moisture. Getting the whole picture right is what separates a lasting result from a quick fix, and it's how we approach every project, from a single-room batt job to a whole-home spray foam package.

It also means we stand behind our work. We install to documented R-values, prep and air-seal before we insulate, and take the time to detail the parts other crews rush — the attic hatch, the soffit baffles, the tricky penetrations. Those details are invisible when the job is done, but they're exactly what determine whether your home is genuinely more comfortable a year later. That's the standard we hold ourselves to on every home in Boulder County.

Whether you're a homeowner chasing lower bills, a family tired of a freezing bonus room, or a builder who needs a reliable insulation partner on a new project, we bring the same thing to the table: real expertise in insulating for Colorado's climate, straightforward advice, and work we're proud to put our name on.
