Spray Foam Insulation in Durango, CO — Built for the High Country.
At 6,512 feet in the San Juan Mountains, Durango's climate punishes under-insulated buildings. On Point Insulation brings building-science-first spray foam and air sealing to La Plata County — from Animas City bungalows to Three Springs new builds to commercial metal buildings in Bodo Industrial Park.
Why Durango Demands More From Your Building Envelope
Durango sits at 6,512 feet in the Animas River valley — classified as IECC Climate Zone 5B, the same zone as Denver but with temperature swings Denver rarely sees. January lows average 12–13°F, snowfall averages 67 inches per year, and the region logs over 7,000 heating degree days annually — roughly 40–50% more than Denver.
Homes beyond Coal Bank Pass (10,610 ft), Molas Pass (10,970 ft), and Red Mountain Pass (11,018 ft) face even more extreme conditions. A building envelope that might perform adequately at lower elevations fails quickly here.
The median Durango home was built in 1989— and roughly 32% of the housing stock predates 1980 — meaning most homes were built under insulation standards that are far below today's code minimums.
If you're heating with propane — common throughout rural La Plata County on Florida Road, in Hesperus, and beyond the Atmos natural gas main — insulation ROI is even faster. At $4–5/gallon, a 30% heating reduction can save $600–$1,200/year on propane alone.

Precision Services for La Plata County
Specialized insulation solutions built for the extreme temperature swings of the San Juan Mountains.
Closed-Cell Spray Foam
The highest R-value per inch available — critical at Durango's elevation. Closed-cell foam is both an air barrier and a vapor retarder, eliminating the moisture infiltration that causes mold in cold mountain climates. Ideal for roof decks, crawlspaces, rim joists, and commercial metal buildings.
Attic Air Sealing
Durango's #1 ice dam prevention strategy. We seal every penetration, top plate, and rim joist before insulating — the step most contractors skip. Meets 3.0 ACH50 code and typically achieves well below it.
Blown-In Insulation
Dense-pack cellulose or fiberglass for topping up existing attics in Animas City bungalows, Bayfield ranch homes, and rural La Plata County properties. Sustainable, fire-resistant, and settles into every gap.
Commercial & Industrial
Metal buildings in Bodo Industrial Park, hotel and hospitality properties, warehouses, and mixed-use commercial in Three Springs. Large-scale closed-cell applications that pay back fast in reduced HVAC load.
Pro Tip:Air sealing alone — before a single board foot of foam — can account for 30–40% of your home's total heat loss reduction.
We Diagnose Before We Install
Most insulation companies show up and spray. We start with data. Building science tools tell us exactly where your home is losing heat before a single board foot of foam goes in.
Blower Door Testing
A blower door temporarily depressurizes your home to 50 Pascals. We measure how much air leaks in per hour — expressed as ACH50(air changes per hour at 50 Pa). The 2021 IECC requires 3.0 ACH50 or better for new construction. A typical older Durango home might test at 8–15 ACH50, meaning it's turning over its entire air volume every 4–8 minutes — bleeding heating dollars straight through the walls.
Infrared Thermal Imaging
Infrared cameras reveal temperature differentials invisible to the naked eye — cold spots from missing insulation, warm streaks from air leaks, moisture pockets from ice dam intrusion. Combined with a blower door, thermal imaging creates a complete map of your building envelope's weak points. We know exactly where to spray and where to seal before we quote the job.
House as a System
Building science treats your home as an interconnected system — not a collection of individual components. Tightening the envelope without right-sizing ventilation can create moisture problems. Adding insulation over air leaks doesn't fix the leaks. We follow Building Performance Institute (BPI) principles: test in, diagnose, install, test out. The final blower door test verifies your home actually performs to spec.

Ice Dams — and the Insulation Fix That Actually Works
Durango has nearly ideal conditions for ice dam formation: heavy snowfall (67+ inches annually), extended freezing temperatures, and a large stock of older homes with inadequate attic insulation. Local roofers — from AMCAT Roofing to PuroClean — call it one of the area's most common and costly winter problems.
Ice dams form when warm air escaping through your attic melts the underside of snow on your roof. That meltwater runs to the cold eaves and refreezes into a dam — backing water under shingles and into your living space. The fix is not a roof product. It's attic air sealing followed by insulation to R-49 or R-60.
Wet insulation from ice dam intrusion also loses R-value and promotes mold — a secondary damage cycle that compounds every winter until the root cause is addressed.
How Ice Dams Form — Step by Step
Warm air escapes through attic floor penetrations, top plates, and bypasses
Roof deck warms from below, melting the underside of snow accumulation
Meltwater flows down to the cold eave overhangs and refreezes
Ice barrier grows, trapping standing water behind it
Water backs up under shingles and into your ceiling or walls
Insulation gets wet, loses R-value, mold develops — damage compounds
The permanent fix:
Air-seal every attic penetration, then insulate to R-49+ with spray foam or blown-in. No more warm air escaping. No more melt. No more dams.
Durango homeowners typically see 20–40% heating bill reductions after attic air sealing and insulation — most projects pay back in 2–4 years.

Every Durango Neighborhood Has Different Needs
We know La Plata County's housing stock — from 1880s downtown masonry to modern Three Springs builds to high-altitude Purgatory condos.
Animas City
One of Durango's oldest districts — Craftsman bungalows and ranch homes from the 1940s–70s. Most pre-date modern insulation codes by decades.
Three Springs
SW Colorado's only Traditional Neighborhood Development — right on US-160. Builders here must hit HERS 90 or better. We know these specs cold.
North Durango / Trimble
Semi-rural homes along US-550 toward Purgatory. Exposed to canyon winds and colder temps than the valley floor.
Historic Downtown
Victorian and Italianate brick buildings from the 1880s–1910s. Classic retrofit challenge: air-seal and insulate without touching historic fabric.
Bodo Industrial
Durango's premier industrial park. Metal and tilt-up commercial buildings lose enormous heat through uninsulated rooflines — spray foam fixes that fast.
Purgatory / North County
Second homes and condos at 8,900 ft on US-550 — beyond Coal Bank and Molas passes. Climate is far more extreme than Durango proper. Premium insulation is essential.
Florida Road / East Animas Valley
A major rural residential corridor with older horse properties and ranch homes. Many are off the Atmos gas main — propane heating means insulation ROI is fastest here.
Edgemont Ranch / Edgemont Highlands
Established planned communities east of town with larger homes from the 1990s–2000s. Often underinsulated at the attic and crawlspace — common targets for a full building science retrofit.
Sunnyside
Northeast of downtown, Durango's working-class and long-established neighborhood. Mix of post-war homes that frequently test at 8–12 ACH50 — above code by a wide margin.
Twin Buttes
Newer master-planned development on the south end of Durango. New construction requires blower-door verification — we work directly with builders to hit the 3.0 ACH50 target.

From the Strater Hotel to Three Springs: 140 Years of Durango Buildings
The Strater Hotel, built in 1888 with 376,000 native red bricks, was originally heated by wood-burning stoves in every room — because there was no building envelope to speak of. In winter, locals left their own drafty homes to stay in the Strater for warmth. That's a 140-year-old problem that still shows up in Durango's pre-1980 housing stock.
Today, Three Springs — the master-planned development right on US-160 where On Point Insulation is based — requires every new home to hit a HERS score of 90 or better, consuming 33% less energy than a standard code home. Fort Lewis College earned LEED Gold on two buildings. Galbraith Builders produced the first LEED Platinum home in all of Southwest Colorado. Durango Green Homes builds Passive House certified structures using 90% less energy than code.
The performance bar in Durango is rising fast. Whether your home was built in 1952 or 2022, there's almost certainly an air sealing and insulation upgrade that will pay back in comfort, lower energy bills, and higher resale value. Homes with better HERS scores sell for 3.5–9% more according to the Home Builders Association of Southwest Colorado — and they sell faster.

Durango Insulation FAQ
Answers to what La Plata County homeowners ask us most.
How much does spray foam insulation cost in Durango, CO?expand_more
Most residential projects range from $1,500 for a crawlspace or rim joist to $8,000–$14,000 for a full attic or whole-house treatment. LPEA rebates, the Colorado HEAR program, and the federal 25C tax credit can offset $2,000–$4,700 of that. We provide itemized quotes at no charge.
Does LPEA offer rebates for spray foam insulation?expand_more
Yes. LPEA members can receive up to $1,500/year standard or $3,000/year income-qualified. Contact rebates@lpea.coop or (970) 247-5786. We help document your project for rebate submission.
Can spray foam stop my ice dams for good?expand_more
Yes. Attic air sealing + insulation to R-49+ eliminates the warm-roof-deck condition that drives the melt cycle. This is the permanent solution — not heat cables, not roof treatments, not annual maintenance.
How long does installation take? Do I need to leave my home?expand_more
Most attic jobs take one day. Two-component spray foam requires occupants and pets to vacate for 24 hours. After the curing window the foam is inert. We help you plan around it during the assessment.
Open-cell vs. closed-cell — which do I need?expand_more
Closed-cell (R-6.5/inch, vapor retarder) is the standard for Durango's Zone 5B climate — especially roof decks, crawlspaces, and rim joists. Open-cell is appropriate for interior walls and sound control. We often specify both on the same job.
Do you work on propane-heated homes and rural La Plata County properties?expand_more
Yes — all of rural La Plata County including Florida Road, Hesperus, and beyond the Atmos main. Propane homes see the fastest ROI: a 30% heating reduction can save $600–$1,200/year at current propane prices.
