Window Replacement in Boulder County, Colorado

Boulder County holds the most demanding energy standards in Colorado, and homeowners here tend to know more about what they're buying than homeowners anywhere else in the Front Range. Both of those things suit us. We'd rather answer detailed questions than avoid them.

Where we work in Boulder County

Boulder, Louisville, Lafayette, Superior, Erie, and surrounding communities.

What Boulder County homes usually need

Boulder's older core. Mapleton Hill, Whittier, and the neighborhoods near downtown carry genuinely historic housing where window proportion and material matter, and where clad-wood is usually the right answer rather than the upsell.

University-area and rental stock. A large share of Boulder’s housing is rental property, which brings a different decision calculus: durability, code compliance, and total cost of ownership rather than aesthetics. Landlords here also face energy efficiency requirements tied to rental licensing, and windows are frequently part of getting a property into compliance.

Louisville, Lafayette, and Superior, 1970s through 2000s. The bulk of the county’s owner-occupied stock is here and these windows are now hitting the age where original double-pane seals fail. Foggy glass is the leading complaint. Much of it is repairable.

Erie and newer Lafayette, 2000s forward. Rapid growth, newer builder-grade windows, wind exposure on the open eastern side of the county.

On Louisville and Superior

Both towns lost far too many homes in the terrible Marshall Fire of 2021. While the homes that have been rebuilt have new windows, the rest of the housing stock largely does not. Roughly 13,000 households sit across those two communities, and the majority are 1970s through 2000s homes aging on a normal schedule that are coming due for repairs, replacements, or upgrades. Picking a local contractor with intimate local knowledge means you're picking a partner that helps you find your home the best solution tailored to its needs, rather than an off the shelf pick that treats a 1970s home the same way they treat a 2000 build.

Energy code and specification

Boulder County jurisdictions run some of the strictest residential energy requirements in the state, and they change more frequently than most counties. Getting the U-factor and solar heat gain numbers right is not optional here, it's a permit condition.

We spec to what the jurisdiction actually requires rather than to a manufacturer's marketing sheet, and we'll show you the numbers.

Permits? Don't sweat it.

Boulder County handles unincorporated areas, and Boulder, Louisville, Lafayette, Superior, and Erie each run their own. We're licensed to pull what's needed and we handle it as part of the job.

Why homeowners here call us

We'll show you the actual performance numbers, not a brochure. If you want to compare U-factor and SHGC across three manufacturers, we can do that, because we carry three manufacturers.

Five manufacturers, not one. Nobody selling a single line can give you an honest cross-brand comparison.

We repair. Seal failure is the dominant complaint in Louisville and Lafayette, and it's often fixable without replacing the window.

We can source dozens of manufacturers. These are the five we know cold.

Being independent means we can match the window to your house rather than your house to a catalog. Compare the brands we install, and if something is failing rather than finished, see what we can repair instead of replace.
