Freddie Vaziri★★★★★7 years ago

Had our whole attic sprayed. The difference between the white fluffy insulation and the spray insulation is like night and day. We had this done in Dec while the temps dropped to 32° and our heater barely kicked in. With our old stuff, the heater would be working all night. The crew was clean and quick. Job done right. What more can I say?

Met with Manuel, he quoted me a good price for removal, repair of rodent entry discovered and installation of new insulation. He arrived on time and provided photos after estimation of job. On the scheduled day, Marcelino and Carlos arrived on time and started working right away. All were friendly and professional and cleaned up everything both days they worked the job. I recommend this business because of the ease it took to get it competed, no effort at all on my part calling them or texting them. Everything was communicated beautifully. Great Job!!! And the price was good!

This company answered right away, came out to provide estimate the same day. They explained every step of the process and how/why they were doing it. They were willing to work around a separate company’s schedule in order to get an hvac system installed. Then come back to add the insulation. They were great with communication, even text me the day before the appt to remind me and give me an eta for a start time.

Bella★★★★★2 weeks ago

I hired Manuel to renovate my attic. He offered the best price. On his first visit, he went up to the attic and took many photos to show me, explaining the process and what type of insulation would be best. His crew was very careful with the floor and walls of my house, and the result in the attic was fantastic.

Highly recommend this company to anyone looking to have their attic cleaned up and re-insulated. We were dealing with HVAC running constantly and still unable to cool down the house effectively. Oumar visited for an initial inspection and came back with a bunch of photos from the attic. He walked us through all the various options we could benefit from, and left us with a competitive quote, without ever being pushy. On the day of service, Dani and his team were extremely professional in their job. They took care of a bunch of rodent mess in the attic and sealed a lot of rodent entry points. They took care of every small task I asked them to do, and left the whole house cleaner than they started with. Attaching some before and after photos for reference. Even though the HVAC still runs constantly, at least it is able to keep up with the heat and bring temperatures down. Just go for them!

Attic Elite team has done a tremendous job at our place. Looking at the before and after picture clearly justifies the amount of effort they had to put in to get things done. They cleaned up the attic and crawl space really well and worked their way with ducts and insulation in the best possible manner. Omar is really helpful in understanding our needs and gave us the best estimate in market which we couldn't refuse. Highly recommend to consult the team for their best services.

DooYoung Jung★★★★★2 months ago

We hired Attic Elite to clean and rodent-proof our church attic, and overall we are very pleased with the experience. Although the crew arrived later than expected, they stayed until the job was done and made sure everything was completed properly. Our attic had been in poor condition for a long time—it was very dirty, dusty, and there were several openings that needed to be sealed. The team worked hard despite the difficult environment. They cleaned thoroughly, removed all the mess, and sealed the holes with care to ensure rodents won’t be able to get back in. It was not an easy project, but they handled it professionally and left the attic in excellent shape. Now our church can use the space with peace of mind, and we really appreciate their effort and attention to detail. Thank you, Attic Elite, for helping us restore and protect our church attic!

Got us sprayed up and cleaned up the job site thoroughly. This was my first time using foam insulation and I had a ton of questions, and Glenn was happy to answer all of them. Looking forward to working with true team again in the future

We couldn’t be happier with the work that Clear Efficiency did on making our home more comfortable and quieter! Other vendors have come through for different jobs and remarked that the attic renovation seemed above and beyond the kind of work they normally see. When I had a couple questions about the job, they didn’t hesitate to come out the same day and help me understand the different aspects of the sealing job they did and how exactly it’s benefiting our energy usage and comfort. A+ 5 out of 5, highly highly recommended.

Damian Dunn★★★★★2 months ago

Had clear efficiency come out in November of 2024 to give quote for attic reseal and new insulation. Don was very professional and explained everything from work to rebates. I then asked about updating my HVAC system in my house and he also went over everything and was not pushy just provided estimates. I was very happy with his service that I got both the attic and HVAC redone with them. Jesse and his team got me right in and worked around my busy work schedule and was even able to get the attic done while I was at work. We did have some hiccups with the rebate for the work but I got all the rebates and I’m very pleased with there quality of work. Would recommend to anyone.

Clear Efficiency supplied and installed eighteen (18) Maxeon Max 3 solar panels at my home (Maxeon’s extended 40-year warranty requires registration). Clear Efficiency is very knowledgeable and experienced, offering me the latest solar panel technology. Their pricing is competitive and the installation was professional and executed on schedule. They submitted the NEM application, took care of the permitting, and provided financing, making the whole processes hassle free. Before this, I was paying high electrical and gas utility bills to PGE. After the first 12 months, my solar panel system generated a surplus of over 3,000 kWh, making me eligible for a Net Surplus Compensation at True-Up. Since then I purchased an electric vehicle and I expect my solar panel system to power most of my home’s electrical energy usage, including a Central Air/Heat Comfort Heat Pump system and Heat Pump Hybrid Water Heater.

I had a GREAT experience getting some of our windows replaced with California Energy Services. Marcus was super responsive, and answered all my questions. He made sure to send out his installer beforehand to make sure all measurements were correct. The install crew was fantastic - very quick, and did a good clean up job. Marcus made sure to stop by the day of install to confirm all went well. Will definitely reach out to them for any future window needs. Their pricing was competitive, and the quality is just what we were looking for.

We recently had our house rewired and the company doing it subcontracted with ace insulation to remove the attic insulation and blow it back in after. I was impressed with the care the workers took to clean up afterwards and to lay down protective material to protect our floors. They were polite and did the work well. I'd recommend them.

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!

I’m writing this review while the Gold Star crew is finishing up one of my projects. This is as good of an outfit as you’ll find in construction. The office staff was super responsive - Jesse came out to visit the job site twice and addressed every concern and helped make the right insulation decisions when the project underwent a major siding upgrade. The crew of installers were polite and friendly; they fulfilled every request and were meticulous with their work. I also need to mention that the job site was left as clean as they found it. I am happy to have found an insulation pro that I can go back to on future projects. Five Gold Stars all the way.

DR K★★★★★a year ago

Two excellent teams to complete the attic insulation. Julio, Arbeno,and Wilzon took out the old insulation. And Neptali and Isidro blown in the fiberglass insulation. Neptali is very helpful, meticulous and knowledgeable in making sure everything is properly sealed for the installation. Thank you for a job well done by both teams.

Frequently Asked Questions — Spray Foam Insulation in Sacramento

These are the questions Sacramento homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 27% typical energy savings. Compare the 17 verified Sacramento contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like Sacramento?▼
Yes — spray foam is highly effective in hot dry climates like Sacramento, 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 Sacramento?▼
In hot dry climates like Sacramento, 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 in Sacramento, CA?▼
In Sacramento, CA 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 Sacramento costs $2,000–$6,000. Most Sacramento 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 Sacramento, CA?▼
When searching for a spray foam contractor in Sacramento, CA, 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 Sacramento 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 Sacramento 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.
