Alex and his team has done multiple projects for me and he’s always on time, does quality work and is priced reasonably. I highly recommend Golden State Insulation for all your insulation needs.

If you are a GC like myself or an owner-builder in the market for an insulation subcontractor, you can’t go wrong with Golden State Insulation. I first started working with Alex about 9 years ago when we were both starting out and I have never had to look for another insulation subcontractor since. His pricing is always reasonable, his communication is excellent and we have never had any issue passing inspections with him. He is extremely helpful with reviewing plans and giving ballpark estimates even before landing a contract and he has always done his best to accommodate our timelines. He and his crew have really kept us in the game over these last few years and we really look forward to many more productive years in business with them.

Cesar and his crew were great! Showed up ready to go and got a lot of work done in 2 days. I had the attic insulation professionally done by them and an installing a hvac system in a house with nothing but a 1970s wall furnace. Cesar was able to get the best sized system for our 1300sqft house, they cleaned up and patched drywall and did a fantastic job. The heat pump system is working great and is so quiet.

Great communication from site visit through to heat pump installation. Element Home Solutions was always available to answer questions and work with me. The install team was clean, courteous, and effective, making sure the site was clean at the end of both working days and finishing exactly as scheduled. Thanks!

Atticare did an excellent job with the attic insulation installation at my home on Dec 2022 (see pictures). Elmer and his crew were punctual and professional. They were thorough during the entire attic insulation installation process. Dylan the project manager did a great job with the initial evaluation process and was able to answer all my questions. He accommodated my last-minute request to reschedule my appointment. I would highly recommend Atticare and will use them again for a future crawlspace insulation installation service on my home.

I cannot speak highly enough of Atticare & their entire team. From my interaction with Gus during the estimating/financial side, to dealing with their PM’s @ our house & project close out, the entire Atticare team were professional, efficient, punctual & professional. We had our attic & crawlspace done, along with insulating our garage roof space in May '23. My wife & I are extremely happy with the results. The work was done over two days, attic first day & then crawlspace the next. Both teams over both days were extremely polite & respectful of our home & protected everything during the work. The Atticare teams removed all the old insulation/debris in the attic & crawlspace, & left the new work looking like a new build. I would highly recommend Atticare to anyone looking to get a competitive insulation job done around their house!

Atticare is one of the best and honest companies I’ve had the pleasure of doing business with. My family recently moved into a new home and we have had a number of random jobs going on at the house. Every time someone went up in our attic space they came down with the same message - evidence of rodents, and minimal insulation. One contractor even removed a recently deceased rat from the attic. I knew it must be disgusting up there. With the summer heat we quickly realized how inefficient our home was. I dreaded the hot days because I knew our AC would barely keep our home comfortable. I wanted to do something about the attic because I knew this was an issue that was just going to get worse and I felt so gross having all that above our heads. I first received a quote from another company to remove the existing insulation, sanitize, seal possible entry points, lay new insulation and install a whole house fan and when they told me the price I knew it was not doable (over $20k). I sadly put that house project on the back burner for a bit. One day I was going through the Valpack coupons and I saw an ad for Atticare. They offered the same services as the first company I had contacted and a discount with the coupon. I figured I would give them a call to see if their prices would be any better. I was able to schedule Leo to come out and give an estimate within a few days. He came out and said the same thing that everyone else has said - that our attic needed a lot of help. He was able to break down the cost of everything per sqft (something the first company couldn’t do). And they were able to schedule the work to be done the following week. At first I told him I wanted to replace our existing attic fan with a new one, but later I changed our order to installing a whole house fan instead (I highly recommend this), and Leo was able to update our estimate without any issue. We needed an electrician to come out and wire for the house fan and they scheduled that for a few days before the attic work was to be done. Super easy. The day came for the attic work and three professional, pleasant, hard working men came out, prepped the entry/hallway spaces with plastic and got to work. They did everything within a few hours, and thoroughly cleaned the spaces when they were finished. We now have a clean, rodent free, appropriately insulated attic with a house fan. All for significantly cheaper than the first quote I received. Our house is so much more comfortable on hot days and our AC finally works well to cool our home. We noticed a difference right away. Oh, and when I told Leo what the first company had quoted me he laughed and said, “someone’s trying to go to the Bahamas!” If you’re thinking about having your attic redone, I highly recommend this company. The job was well explained and executed professionally. Thank you Atticare!

Frequently Asked Questions — Spray Foam Insulation in Hayward

Does spray foam insulation work well in hot dry climates like Hayward?
Yes — spray foam is highly effective in hot dry climates like Hayward, 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 Hayward?
In hot dry climates like Hayward, 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.
