Amazing. Top to bottom, this company is the best. Ron made me feel like I made a new friend. Knowledgeable and friendly. No upselling. In and out with a smile the whole time.

I haven’t been so impressed with a company in a long time and it was during a tough time when our heater went out. CES went above and beyond to take care of us. Ron their technician, Marcus their Project Manager, and Rodger the owner all had a hand in our experience. CES wasn’t the only company I spoke to and they weren’t the only company that came out to our house to diagnose what the problem was, and provide quotes. I was quoted crazy amounts to replace the whole system, but CES was the only company that quoted only the components that needed replacing of which brought our cost way down. Ron made sure everything was perfect before he left our house. Marcus spent an hour and a half in our kitchen trying to update the software on our thermostat which was outdated. We ended up having to replace the thermostat too, but Rodger made sure it was affordable for us. I can’t say enough good things about CES. Bottom line is we received excellent service in a reasonable time, an updated heater, and all at a reasonable price. Sheron A.

We chose California Energy Services to replace the windows in our whole house after bidding 5 or 6 companies. Marcus was our rep and he was never pushy or sales - which is something I really appreciated. He was knowledgeable and genuine. The windows I chose were a newer style and took longer to manufacture. Marcus kept me updated and informed along the way via text, phone, or email. The installation team was also great! They worked around my work schedule and started in my office so that I could prepare for a virtual presentation the following day. They also took care of my home, from carefully removing and reinstalling my window coverings to cleaning up the inside and outside. We used "new construction" for the install so there was quite a bit of mess that I never had to worry about. When the installation was complete, we did a walk through and Loren (on the install team) made me feel comfortable to point out anything that I noticed or wanted corrected. The only thing I noticed was a bent screen and he happily ordered a new one. I would definitely recommend CA Energy Services as a reputable, honest, and quality company.

I have used Sierra Insulation for fifteen years. Good prices and service.

M.E. Reed★★★★★4 weeks ago

Both our QII inspector and our County Building Inspector were very pleased with the job Sierra Insulation Co. did on our ADU. The county inspector walked in, and said, "This looks good. You would think insulation would be a fairly easy part of the building process, but so often I see it is not done correctly." Thank you, Sierra Insulation Co!

Frequently Asked Questions — Spray Foam Insulation in Folsom

Does spray foam insulation work well in hot dry climates like Folsom?▼
Yes — spray foam is highly effective in hot dry climates like Folsom, CA. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in Folsom?▼
In hot dry climates like Folsom, CA, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most conditioned air.
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.
