Insulation & Air Sealing in
Lafayette
Lafayette was founded in 1888 as a coal town, and the city’s own plan credits mining, farming, and the railroad for the community it became. Old Town still holds the houses those mining families built, while the neighborhoods around Waneka Lake and Indian Peaks date from the 1980s and 90s. The median home was built in 1994, in a county where one in two homes tests high for radon.

Why Lafayette Homes Are Different
A coal town built over its own mines
Here is the part nobody puts on a listing: the U.S. Geological Survey maps the Lafayette area as undermined, part of the Boulder-Weld coal field, and notes that ground affected by collapse over old workings can extend past the mapped mines. We do not fix subsidence, but we do see what it does to a house envelope: racked framing, gaps at the sill, and cracks that leak air.
Old Town coal-camp houses
Small frame homes from the 1880s to the 1930s with no wall insulation, plaster, and attics that never saw anything close to a modern depth of insulation. Dense-pack and air sealing change them completely without touching the character.
1980s and 90s subdivisions
The homes around Waneka Lake, Centaur Village, and Indian Peaks have skimpy attic batts, open rim joists, and first-generation builder windows. Seal, then top up; that is the best dollar.
Settled and shifted framing
On undermined ground, houses move. Gaps open at the foundation sill and around window frames, and those gaps leak air long before they show as cracks. A blower door finds them.
Boulder County radon
Boulder County Public Health says one out of every two homes in the county has elevated radon. There is no way to know without testing.

Diagnostics
What we commonly find in Lafayette 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.
Sill plates that opened up
Movement over old mine workings opens a gap between the foundation and the sill in many Lafayette homes, a leak that runs the whole perimeter and is easy to miss from inside.
Uninsulated coal-camp walls
Old Town frame walls were built empty and most still are. Dense-pack is the fix, and the difference in comfort is immediate.
1990s attics at half depth
Attic insulation from the Waneka Lake era went in at a 1990s standard, far under today’s target, and has settled since.
Duct joints that leak
Crawl space and attic duct runs in both eras leak at every joint. Sealing every joint and wrapping the runs pays back fast, and nobody sees it.

Local Rebates
Rebates for Lafayette addresses
Lafayette runs on Xcel Energy for electricity and gas. Xcel pays up to 60% of a home energy audit, rebates insulation, air sealing, and HVAC work separately, and adds $600 on a heat pump installed after the envelope is fixed. Amounts change, so we verify them for your address before quoting and file every form.
Boulder County’s EnergySmart program changed in late 2025: the standard rebates were retired, and for 2026 it is income-qualified only, paying up to 50% of project cost, up to $2,000 a year, for households at or below 100% of area median income, on insulation, air sealing, heat pumps, and heat pump water heaters, with free advising for everyone. The city’s own 1-2-3 Electrify page is a guide, not a rebate. Power Ahead Colorado’s $1,500 heat pump rebate pays only through contractors the program has verified, which PowerHouse is not today, so we explain it rather than promise it.

Lafayette questions, answered
Is EnergySmart still paying rebates in Lafayette?
Only income-qualified ones in 2026, up to 50% of the project and $2,000 a year for households at or below 100% of area median income. The free Electric Coach advising is still open to everyone. Xcel’s rebates apply to every address, and we file those.
Can you insulate an Old Town house without wrecking it?
Yes. Dense-pack is blown into the existing wall cavities through a handful of small openings, the attic gets air sealed and topped up, and the rim joist gets sealed. The house keeps its character and gains a real envelope.
My house has settled. Does that change the work?
It changes where we look. Settled homes leak at the sill plate and around window and door frames. We seal those with the right materials for a house that is still moving slightly, then insulate.
Should I do insulation before a heat pump?
Almost always. It earns Xcel’s $600 envelope-first bonus and lets us size a smaller heat pump that runs less.
How bad is radon in Lafayette?
Boulder County says one in two homes is elevated. Test first; mitigation fixes a high reading and keeps it fixed.
