This company did a crawl space encapsulation and radon mitigation system for me. They were wonderful. Great guys, on time, left the place cleaner than it was. Highly recommend!

Billy Hubbell★★★★★8 months ago

Connected with Ascend through the Fort Collins energy rebate program. Talked with Lizzy on the phone and Chris came out for the estimate. Super easy to work with and great communication all around. We decided to have our attic sealed (spray foamed) and new blown-in insulation installed. When it came time to do the work, Pete and crew were all very polite, professional and kept our home clean during the process. Again, communication was outstanding. Never was I wondering where we were at in the process or what was happening next. Work was completed on time with no outstanding issues. Highly recommend and will use them again for future projects.

Everyone at Ascend was incredibly warm, helpful, and professional. They did an excellent job with my installation, and were communicative at every step. Further, they helped explain how to apply for a rebate from my energy company and walked me through the tax implications in a clear way that made everything go smoothly. I cannot recommend them enough!

Kevin is awesome and clearly loves his company and the industry he is in. We needed our crawl space and garage to be insulated. He went far above and beyond what we could have ever hoped for. It turned out amazing! The work was clean, professional and affordable. Not sure what else you could ask for!

My wife and I worked with Ben and his team to get our roof rebatted. He did a fantastic job walking us through the process and was extremely communicative. I would highly recommend Ben and LL Insulation for new or existing insulation needs.

Frequently Asked Questions — Spray Foam Insulation in Fort Collins

These are the questions Fort Collins homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 37% typical energy savings. Compare the 7 verified Fort Collins contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Fort Collins?
In cold climates like Fort Collins, CO, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in CO typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Fort Collins?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Fort Collins, CO. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Fort Collins?
For cold climates like Fort Collins, CO, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with CO building codes can recommend the exact specification for your home.
Is spray foam insulation worth the cost?
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Fort Collins, CO?
In Fort Collins, CO and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Fort Collins costs $2,000–$6,000. Most Fort Collins homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Fort Collins, CO?
When searching for a spray foam contractor in Fort Collins, CO, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Fort Collins contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Fort Collins for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
