I'm extremely impressed with the service I received from 'The Insulation Guys'! Jesse, the owner, and his team did an outstanding job insulating my old house, which was a challenging project. The house had old insulation that needed to be removed, along with debris from a recent roof replacement. Jesse and his team took care of everything, leaving the attic spotless. What really stood out was Jesse's excellent communication throughout the project. He walked me through the process, explained everything clearly, and kept me updated on the progress. To accommodate my remodeling schedule, Jesse split the project into two phases. First, they removed the old insulation and debris. Then, once all the other remodeling projects were completed, they returned to install the new insulation. I'm thrilled with the result, and I highly recommend 'The Insulation Guys' to anyone looking for professional, reliable, and courteous service. Jesse and his team truly care about their customers, and it shows in their work. Thanks, Jesse and 'The Insulation Guys' team, for a job well done!"

Jesse and the entire crew from My Insulation Guy did a great job refreshing and adding blown in insulation into my attic space on Christmas Eve. From the get go, Jesse was extremely responsive and had great communication when I was getting quotes. Jesse sent me links to educate me on the pros and cons of cellulose insulation vs fiberglass blown in, which was great because I am one of those shoppers who does a lot of research on what I am purchasing. Pricing was straight forward and was the lower priced bid for a better product. The install team of Corry and Logan were also great. Corry was very personable and kept me posted on each step of the install. They tarped everything off and cleaned up everything before they left. These guys are up front and honest, they ended up blowing less insulation than quoted and Jesse adjusted the agreed upon price to a lower cost to match the square footage they actually did. Very happy with the crew from My Insulation Guy and will be referring them to any of my friends who need insulation work done! Highly recommend!

Overall I am satisfied with the quality of work performed for a reasonable price. In my particular situation I had 2 to 3 inches or insulation stained with rat feces. I also had holes in my ducts, and was looking to replace it all primarily for sanitary reason and any energy efficiency gained was an added benefit. For my needs they perform the work I needed quickly and professionally. Things to consider. I perhaps would have liked a little bit more communication up front a bit more details for someone never had done any of this type of work. Jesse was responsive via text but some additional details would be appreciated. They did 99% amazing job. I crawled through attic after they removed insulation found very little (the size of a penny) insulation in some corners left over not a big deal considering the mess up there (wood debris from when the roof was replaced) and they cleaned areas i that I could not reach and was skeptical they could reach but they did! They replace all my ducts, and installed new insulation. They did a great job there as well. The 1% was there was a bit of insulation left behind on the grass (from when the machine got clogged from all the debris in the attic) and they did sweep to clean up but still a little left. To there credit I pass the lawn mower and it didn't pick up either because my lawn is so uneven but it's not a big deal just noting for the really picky clients. I did get quotes from some big names which were more expensive, those guys came did a walk thru to give me a quote, they were very convincing but the reason I didn't go with them is my friends who used them had many more issues compared to the very minor issue (small amount of insulation left on grass) and they are still arguing with the big names to uphold those warranties. So felt like a took a bit of a risk with Jesse but I'm glad I did so.

We decided to go with Attic Advisor because Dominic who came out to quote us was honest and had a lot of integrity. They also have competitive prices and seemed to be most thorough. We are very happy with our choice in who we picked to go with. Every employee we have worked with has been nothing but kind, understanding, and easy to work with. Our attic was a disaster and now it is fixed up, cleaned up and properly insulated. They also did a great job containing the debris as I am pregnant and very grateful the protocols they took to look after our health.

Can't say enough good things about the work by Dominic, Tyler and the Attic Advisor team on their work at our new home. The work entailed vacuuming out decades-old insulation from our low-pitch attic, cleaning up past rodent infestations, patching up seams and vent gaps, then returning at a later date to sanitize and clean the attic before installing new blown-in insulation. Throughout the entire process, Dominic, Tyler and their team were respectful of the property, responsive to questions, and flexible when I needed to move dates around because we had other work going on. Everything looks great. I really appreciate the work done by Attic Advisor!

Rebecca Kelly★★★★★3 years ago

Attic Advisor cleaned my attic, did rodent control and laid insulation. The salesman, Dominic, did a thorough inspection of the attic and gave me a reasonable estimate. He explained the issues and the remediation so well that I totally understood everything. Aaron the project manager along with Felix showed up shortly after I accepted the estimate. They were great. Aaron did a fabulous job of explaining all the work that had been done, along with showing me the photos. And I don't want to forget about David- the point of contact and office coordinator. He was always available to answer any of my concerns. I would highly recommend this company.

Frequently Asked Questions — Spray Foam Insulation in Riverside

These are the questions Riverside 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 4 verified Riverside contractors above for exact quotes.

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