Local insulation across Boulder County
From historic bungalows in Boulder to new builds in Superior and mountain homes up in Nederland, we insulate homes across the county — and we tune every job to the town, the elevation, and the way these homes are built. Here's where we work.

Insulation isn't one-size-fits-all, and neither is Boulder County. A 1920s bungalow on Boulder's Hill has completely different needs than a 2015 build in Superior or a home at 8,000 feet in Nederland. Elevation changes how cold it gets and how hard the wind blows; age and construction style change where a home leaks and how its walls are built. A crew that works these homes every day knows what to look for and what actually works here.
Being local also means we know the local programs. Boulder and Boulder County have some of the most progressive energy codes and rebate offerings in the country, and staying current on Xcel Energy incentives, Boulder County programs, and federal tax credits is part of our job. When we quote your project, we build it to qualify for what's available so you keep more of the savings.
Whether you're in Boulder, Longmont, Louisville, Lafayette, Superior, Niwot, or Nederland, you get the same thing: a careful assessment, honest advice about what your home actually needs, a clean professional installation, and a warmer, more efficient home at the end of it.
Boulder County's housing is wonderfully varied, and that variety is exactly why local knowledge matters. Boulder itself ranges from century-old homes near downtown and the University to modern builds in the foothills, each with its own quirks — knob-and-tube-era framing, additions layered on over decades, or vaulted great rooms that are notoriously hard to insulate. Longmont and Lafayette bring a big mix of mid-century and newer subdivisions, while Louisville and Superior saw significant rebuilding in recent years that put a premium on tight, high-performance envelopes. Niwot's acreage properties and Nederland's mountain homes sit at higher exposure and elevation, where R-value and air sealing matter even more.
We've worked across all of it, and we tailor every job to the home in front of us rather than applying a one-size template. That's the advantage of hiring a crew that lives and works in Boulder County: we already know how these homes behave in a Front Range winter, and we know how to make them better.
