Wonderful service. Bradon was amazing, he let us know when he was going to be here , was polite and checked in to make sure the service was good which it was! I Would love to have him back for service again with his genuine smile and polite personality.

Mr Brandon Smiley was very friendly and polite, had a smile on his face while doing his job and was able to do it quickly, and efficiently. We have a dog and he greeted her with a friendly hello and petted her gently. I was very satisfied with his visit.

I've had Homeshield come out for the last year ever since I started to notice the largest spiders I've ever seen in my backyard. They always do a wonderful time. This time I had a small wasp nest inside my shed and Bradon did such an amazing job. He talked me through what he would do to remove the nest, made sure to take his time so the wood of the shed wasn't damaged, and then let me know what to expect over the next couple days as the wasps adjust to having their nest removed. He was so friendly and informative. Highly recommend HomeShield

This home builder is horrible. We and our whole development, have had nothing but problems. Many buyers from the Vanden Ranch development have started legal action and the homes are subpar quality. Half of us didn’t even pass initial inspections from the county and VA appraisers. Please research before considering this home-builder.

Our experience with the sales staff was mixed. Our original sales person was okay but our final sales lady, Jennifer, was great. She helped us get the house we wanted and is still helpful when we need her today. The service and maintenance department leaves something to be desired. That adventure started when they rushed finishing our home so our move in could fall into the current month. The house was not ready and though we purchased a brand new home, it was not in the perfect condition I expected. Additional issues have been construction debris not being cleared from gutters after build. We were told that at our one year walk through anything we needed repaired would be done. This was not true, touch ups and recaulking were not completed as promised. Our biggest issue that is still not resolved is a plumbing issue where the PVC in front of the house became detached. It did not crack or break from outside force, it literally separated which would be nearly impossible had the pipe been properly glued and attached during the build. The head of maintenance advised us to have a plumber out to repair as he couldn't reach the original plumbers. Once work had been completed, we were essentially ghosted by him. We took our issues to the Customer Service Manager after months of waiting and he is now trying to low ball our reimbursement. We are out $4,500+ for a mistake made during the build of our home. Buyer beware. Get an underground plumbing addition to your homeowners warranty because the builder is not interested once you purchase!

Frequently Asked Questions — Spray Foam Insulation in Vacaville

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