Serving Boulder, CO
Insulation & Air Sealing in
Boulder
No city in our territory takes home efficiency more seriously than Boulder, and few have older housing bones to work against. That tension is exactly our specialty: bringing pre-war and mid-century homes up to the standard Boulder homeowners actually expect.

Why Boulder Homes Are Different
High standards meeting old housing stock
Boulder wants electrified, efficient, healthy homes, and much of its most desirable housing was built before any of those words meant anything.
Pre-war and early post-war homes
Uninsulated wall cavities, original wiring, and charming single-pane windows. These homes respond beautifully to dense-pack insulation, careful air sealing, and modern glazing.
Electrification demand
Boulder leads the region in gas-to-electric conversions. Heat pump retrofits, panel upgrades, and EV-ready electrical work are everyday projects for us here.
Solar-first orientation
Boulder’s sun exposure and energy attitudes make solar a natural layer, sized correctly after the envelope is fixed so you buy fewer panels for more coverage.
Boulder County radon
Zone 1 geology under some of Colorado’s most valuable basements. Testing and mitigation are standard practice in Boulder transactions.
Diagnostics
What we commonly find in Boulder homes
These are the patterns that show up repeatedly in this housing stock and climate. Your home gets tested, not assumed, but this is where we look first.
Uninsulated wall cavities behind plaster
Many of Boulder’s most desirable homes have never had wall insulation at all, and dense-pack reaches those cavities without disturbing original plaster.
Electrical service too small for the plan
Older homes commonly still run 100-amp panels, which becomes the actual constraint the moment a heat pump, induction range, or EV charger enters the conversation.
Finished basements over untreated slabs
Basement living space built without a capillary break or radon-aware detailing puts the highest-occupancy room closest to the source.

Local Rebates
Rebates for Boulder addresses
Boulder-area homes are largely Xcel Energy territory: audit rebates up to 60% plus rebates on insulation, air sealing, and HVAC upgrades, and Boulder County runs its own efficiency programs that can add advising and incentives on top.
Electrification projects stack Colorado heat pump incentives, up to $3,500 combined for qualifying installs. We build the full stack for your address and file everything.

Boulder questions, answered
Can you insulate old Boulder homes without gutting walls?
Yes. Dense-pack blown-in insulation goes into closed wall cavities through small access points, transforming pre-war homes while preserving plaster and character.
Is my panel ready for a heat pump and an EV?
Often not: many Boulder homes still run 100-amp service. We evaluate capacity as part of any electrification project and handle the panel upgrade when the math requires it.
Should solar come before or after insulation?
After, almost always. Fixing the envelope first shrinks the system you need, which means less roof, less cost, and more of your usage covered. The audit sequences it correctly.
Do you work with Boulder’s efficiency programs?
Yes. Between Xcel rebates, county programs, state heat pump incentives, and the metro’s Power Ahead Colorado heat pump rebate, Boulder projects can stack more support than almost anywhere, and we file all of it.
How serious is radon in Boulder?
Boulder County is in the EPA’s highest-risk zone, and finished basements make exposure more relevant, not less. Test first; mitigation reliably solves elevated results.
