I contacted NetZero to get a quote on updating the insulation in one part of my house. I received a detailed quote from Ryan that included my original ask, and an update to the other attic spaces in the house including air sealing that was cheaper than just the one service due to Ryan's comprehensive knowledge of the rebates offered by Xcel and the federal govt. Ryan and his team completed a full update to all my attic space insulation (knee walls, air sealing, updating to R60 insulation) for the same cost as me finishing one space DIY. His large team came in and finished the improvements in one day and cleaned up so well it was like they weren't there. One month later, my electric bill is down 29% and my gas bill 10%. Best home improvement purchase I've made to date!

We used NetZero Insulation for our previous home in Lone Tree and were incredibly impressed with the pride their team has in their work, as well as their competitive pricing. They installed insulation in my parents' home in Castle Rock, and in our new home in Castle Rock. They finished last July, our Nest noted that we used 80 hours less AC in August compared with July. Our home is SO much more comfortable, and the noise insulation has increased dramatically as well. Our family highly recommends Ryan and his team at NetZero.

NetZero air sealed my attic/garage and installed new insulation lat week. I was skeptical on how much we’d really notice, but the temperature difference of my top floor and rooms over the garage has been incredible. Ryan and team were incredibly clean, professional, and quick. They operated in unison with each of the 7 workers knowing exactly their role. Very impressive company/staff. Highly recommended!!

Montgomery Insulation did an amazing job insulating my ceiling via attic crawl space I’m extremely happy , I will always hire this Company for any insulation needs thank you!

John Bamford★★★★★3 years ago

Jason and his employee installed insulation up to code in a half day in my home, used plastic to protect floors, cleaned up after and built barriers to keep insulation in proper place. I inspected after and saw a complete and professional job.Very pleased. My furnace ran only once during the night so expect my heating costs will drop quite a bit. I am picky about work quality. Thanks, Jason.

I used Montgomery Insulation to insulate my walls and crawl space and just wanted to say that they did a really good job on both. The wall insulation was really dirty, but they covered everything in the rooms with plastic and when they were done, they dusted and vacuumed so that it was actually cleaner then before! Small business, nice people.

Frequently Asked Questions — Spray Foam Insulation in Littleton

Why is spray foam insulation especially important in cold climates like Littleton?▼
In cold climates like Littleton, 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 Littleton?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Littleton, 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 Littleton?▼
For cold climates like Littleton, 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?▼
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. 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 costs $2,000–$6,000. Most 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?▼
Look for contractors 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 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 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.
