Why Fort Collins Homes Are Different
A city with three generations of housing problems
Fort Collins grew in distinct waves, and each wave left its own signature issues. Knowing which era your home comes from is half the diagnosis.
Old Town and campus-area homes
Pre-war construction with balloon framing, plaster walls, and original wiring. Blown-in insulation and knob-and-tube removal are common projects here, and they transform how these homes feel.
Mid-century ranches
Solid bones, thin attic insulation, and ductwork designed for a different era. These homes respond dramatically to air sealing plus attic top-ups.
Newer south-side builds
Tighter construction that shifts the conversation to ventilation, air quality, and right-sized high-efficiency equipment.
Zone 1 radon county
Larimer County’s geology puts Fort Collins homes squarely in the highest radon risk category. Real estate transactions here almost always involve testing now.
Diagnostics
What we commonly find in Fort Collins 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.
Balloon-framed wall cavities
Pre-war Old Town homes often have open stud bays running floor to attic, which turns the wall assembly into a chimney until it is dense-packed.
Knob-and-tube still energized
Original wiring shows up regularly in the oldest neighborhoods, and it blocks safe insulation work until it is removed.
Duct runs through unconditioned attic
Mid-century ranches commonly push conditioned air through uninsulated attic ducts, losing a meaningful share before it reaches a register.
Tight new builds with no ventilation strategy
Newer south-side homes seal well but often lack balanced mechanical ventilation, which shows up as stale air and winter humidity on windows.

Fort Collins questions, answered
Do you work on Old Town historic homes?
Yes, and we love them. Blown-in wall insulation, careful air sealing, and knob-and-tube removal are all standard work for us in pre-war Fort Collins homes, done without wrecking original character.
What is Efficiency Works and do I qualify?
It is the efficiency program for Fort Collins city utility customers, offering deeply discounted energy assessments and rebates on insulation, air sealing, and equipment upgrades. If the city bills your utilities, you almost certainly qualify, and we handle the process.
My second floor is always hot in summer. Is that normal here?
It is common, not normal. In most Fort Collins two-stories it traces to attic insulation and duct balance, not a failing AC. An energy audit pinpoints it before you spend money on the wrong fix.
How bad is radon in Fort Collins?
Larimer County is in the EPA’s highest-risk zone and Fort Collins homes test above the action level constantly. Testing is cheap certainty, and mitigation systems reliably bring levels down.

Yes, the whole city and surrounding Larimer County, from Old Town to Harmony corridor and out to LaPorte and Timnath.
