I'm so happy we finally called McHale's Environmental! We knew some rooms in our house were poorly insulated because they were always either freezing cold or blazing hot. The previous owner had extended the house, and it seemed like the builder cut corners and skipped insulating the exterior walls. For four years, we'd relied on portable heaters in the winter just to make those rooms bearable. John was incredibly helpful – he walked me through the house, confirming exactly where the insulation was missing. Their quote was competitive, and the installation crew was fantastic: efficient, friendly, and they cleaned up perfectly. Unlike other companies that use larger holes, McHale's process utilizes a smaller 1.5-inch cutout, which I appreciate because it means better insulation. The difference is unbelievable! Since McHale's insulated the rooms, we haven't had to use a single portable heater. I can't believe we waited so long to do this. Highly recommend McHale's!

I recently had a fantastic experience using McHales for insulation at my house. Dan came out to my house to review the plans and provide a quote. He was very honest and did not try to upsell anything! A few days later, Dan's crew came out to complete the installation. They had everything completed in just a couple days. The crew was very professional and cleaned up each evening! It's only been about a month, but you can drastically feel a difference in temperature throughout the house! I would highly recommend McHales if you are looking for a great/smooth experience.

Great experience with McHales Environmental Insulation! John came over to our home, identified which walls did not have existing insulation, took measurements and provided cost quote bid for blow-in insulation the following day. We scheduled the job, and the crew came over on time and walked us through what they were going to do. They completed the job within a few hours, patched holes nicely, and cleaned up their work areas. We have felt a noticeable difference in our home insulation since the job was completed. They also helped us process an energy rebate. We would recommend McHales to anyone looking for blow-in wall insulation!

Insul-Techs were hired to insulate my house. The scope of work involved insulating my walls, attic, and crawl space. The team installed different R value fiberglass insulation in the attic, walls, and crawlspace. They also installed spray foam insulation in one of my vaulted ceilings as shown in the pictures. I also got my garage walls insulated so that I can use that as a gym year round. They did an amazing job and after they were done with the insulation, we felt the difference on how cooler the house felt even when it was really hot outside Chris helped us with the scheduling and was a delight to work with. They are a hard working team who catered to all our requests and did everything to ensure we were satisfied with the job before they were done. Thank you Insul-Techs!

I was referred to insultech from a respected contractor. Luis came by for an estimate. During the inspection i was given options on the types of insulation and the insulation factor of each method. After further review of other insulation companies non were as professional in explaining the process or the materials used, and most of all they were much more expensive for the same work being chosen. The techs came in completed the job with the utmost respect for property. Communication with Luis and the front office was effortless and the response was done in a timely fashion. The insulation factor coupled with the mini split for cooling. What a difference. Customer satisfaction comes first. Great job InsulTech.

I recently had Insult Techs replace the insulation in my home, and they did a phenomenal job! The difference it made was immediate and noticeable. Their customer service was excellent from start to finish, and their pricing was very competitive compared to other companies I looked at. Luis and his crew were professional, efficient, and respectful throughout the entire process. It was truly a great experience, and I highly recommend Insult Techs to anyone needing insulation work done.

Karen Jodel★★★★★8 years ago

Richard and David Abril go above and beyond to satisfy their customers. I've used Abril roofing many times in the past but this time my roof was exposed and needed repair urgently. David worked closely to fit me into the schedule before the raining season. The are honest, fairly priced and have a good crew. Highly recommend Abril Roofing.

Our recoat applied in August of 2023 began to blister and grow algae under the bubbles within months of the job. Multiple texts, photos, a phone conversation and a personal visit by the owner have failed to provide the promised repair.

Frequently Asked Questions — Spray Foam Insulation in Concord

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