Jesse and his team were extremely professional and responsive. This team truly cares about your needs and is here to help. They took the time to meet and greet me and truly understand my insulation needs. They got in my attic in the freezing cold and game me my best option.

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!

NetZero was a tiny bit more expensive but by far worth every penny. They were thorough, professional and easy to work with. The work was completed on time and we can't believe the change in the comfort of our house. They took the time to prep everything and protect our belongings. The crew was polite and friendly. We highly recommend them.

Review of Dec 2025 project, 1 year later. Ryan and team did an excellent job...removed old rockwool batting insulation, air sealed the attic, blew in new fiberglass insulation to R60, sealed and insulated crawl space, installed bathroom fans and more. Cleaned up everything perfectly. Everything was on time and as scheduled. Couldn't have asked for a better job. Thanks Ryan and team!

Excellent attic insulation removal and upgrade experience. Corrie did a thorough inspection, providing photos of all the key areas in the attic that needed to be addressed. Walked me through the various insulation options - and notably I did not feel pressured to go with the most expensive solution - she indicated for our type structure it wasn't the best path. On the day of the install, the team was on time and knew exactly how to proceed. Minimal interruptions, and again when complete, they provided many photos showing before / after. Team also performed the tests needed to qualify for the Xcel rebates and everything passed successfully. Excellent experience overall - highly recommend.

We had a great experience with Koala Insulation for our attic insulation project. Their team removed the old insulation, sealed up air gaps, and installed new insulation up to the recommended levels—including in a tight, hard-to-access attic space. From the start, they offered multiple options and quotes, were responsive to all our questions, and communicated clearly throughout. On the day of the job, they arrived on time, worked efficiently, kept everything clean, and made sure to explain every step of the process. Even the blower-door follow-up was scheduled quickly. Every person we dealt with was professional, patient, and knowledgeable. Now that summer is here, we're already noticing reduced heat in the house and enjoying the energy savings. Highly recommend Koala Insulation if you're looking for quality work and great service!

We called to get some more information and just overall help. Corrie was extremely kind, professional and quick with answers. She even did some calling around for us and helped point us in the right direction instead of us going down the rabbit hole ourselves. Amazing service thank you so much!

I hired RG Insulation to install baffles and blow additional insulation in my attic. Everyone I dealt with from the salesman who quoted me the price to the two gentlemen who performed the work were very professional. They took care to protect my floors and prevent mess. They did an excellent job in a short period of time and then made sure I pleased with their work. Plus, their price was excellent as compared to competitors. Highly recommend!

Frequently Asked Questions — Spray Foam Insulation in Englewood

These are the questions Englewood 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 5 verified Englewood contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Englewood?▼
In cold climates like Englewood, 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 Englewood?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Englewood, 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 Englewood?▼
For cold climates like Englewood, 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 Englewood, CO?▼
In Englewood, 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 Englewood costs $2,000–$6,000. Most Englewood 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 Englewood, CO?▼
When searching for a spray foam contractor in Englewood, 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 Englewood 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 Englewood 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.
