We just had spray foam insulation done, and I can honestly say we’re so glad we did it. After getting a few quotes, we chose Koala Insulation because of their great reviews and how easy and knowledgeable Jim (one of the owners) was to talk to. Their price was right in line with the others, but their professionalism and expertise stood out. Our attic was a bit tricky, but they handled it really well—from the insulation removal to the final spray foam, they took great care of everything. Even better, they were super respectful of our home and really kind to our family. Huge thanks to Ryan and Mike (techs), Sean and Gabe (spray foam), and Noah (drywall). And a special shoutout to Jim and Bill—great guys and great to work with. It’s already been a few warm days and we’ve noticed a real difference in comfort. Highly recommend these guys!

The estimate process was easy and prompt. Service technicians were professional and well versed in their product and their work. We had insulation blown into our attic and solar attic fans installed and they did a great job. Kept us informed and didn’t leave a mess. Great experience!

Steven Marks★★★★★a year ago

Koala Insulation did a fabulous job on providing our attic with additional insulation and installing a solar powered attic fan. Bill, the owner, provided us with an honest assessment of our house and recommendations. Simeon and Ryan did the insulation installation and over saw the roofer who installed the fan. They were both great! All are very friendly and dependable! Would recommend without hesitation!

Sun Flex installed a new roof on our AZ room. Thomas and the crew were very professional. Plastic sheeting was applied to protect my neighbors from overspray. From start to cleanup, a very good job. We’re extremely satisfied and highly recommend Sun Flex.

I found Sun Flex through a Google search for “roofers near me.” This search proved to be a wonderful find. Thomas of Sun Flex is an experienced professional while being personal and honest. He clearly explained what needed to be done, how he was going to do it, and the pricing. The crew was considerate and professional as well-knew what they were doing; got the job completed and cleaned up in a timely manner. Since the roof was foam coated, the room is noticeably cooler!

Lorelei Harder★★★★★3 weeks ago

We had wind damage at our property during the summer while we were away (snowbirds). I called Sun Flex who had done work on our roof previously. Thomas assured me they would be out to look at it asap. True to his word our place was inspected and repaired within a couple days…and right before a huge rainstorm. I couldn’t be happier with the quick response and repair, saving us further damage. Everything looks great!! Thanks again Sun Flex!

"Great experience with Attic R Us! They did an amazing job with my attic insulation and rodent proofing. The team was professional, punctual, and very knowledgeable. They explained everything in detail and provided excellent recommendations. My home is now warmer and more energy-efficient. Highly recommend Attic R Us for all your attic needs!"

Mark★★★★★a month ago

Extremely well done job by Attic R Us! I had a mix of blown in insulation and batt insulation. They first cleaned the entire attic out (not an easy job, and over 30 years of insulation, dust, and trash). They did an incredible job cleaning it all out. The spay foam insulation was installed pretty quickly - they were extremely thorough. Other insulation providers will sell against spray foam insulation - typically say it smells - However, while there is a smell the first day, this quickly dissipates and you won't know the difference. It's a much better seal than any other kind of insulation as well. The house in Scottsdale is a rental, so if there were any adverse side effects I'd definitely hear about it - I also have spray foam insulation in the house I live in and can confirm no issues with smell or anything else. Highly recommend due to their hard work, fair pricing, and professionalism. I only wish I took before/after pictures to show just how good of a job they did!

After numerous companies came out and multiple failed attempts to solve our rodent problem, Attic R Us was the only company that truly fixed it. By that point, the stress and ongoing concerns about our family’s health and safety were overwhelming, and we were exhausted and losing hope. From the start, Attic R Us treated this as a serious health and safety issue, not just a nuisance. Their crew was always respectful, professional, and careful in our home, which meant a great deal during such a difficult time. A huge thank you to Miguel, who was outstanding from beginning to end. He presented with confidence, clearly knew exactly what needed to be done, and made the entire process feel easy and manageable. Miguel kept me informed every step of the way, explained what previous companies had missed, and ensured nothing was overlooked. His calm, knowledgeable approach gave us confidence for the first time. After several companies failed, Attic R Us identified the true source of the problem, sealed the attic properly, and finally ended the infestation. Knowing our home is now safe and rodent-free has brought us priceless peace of mind. I highly recommend Attic R Us to anyone who has tried everything else and wants the problem solved the right way.

If you’re looking for spray foam insulation, this is the place to go. Everything was perfectly sealed. Most importantly, the place was left clean without any debris for me to have to deal with. Punctual and friendly and definitely easy to deal with..

I recently hired this insulation company to remove our old insulation, and I couldn’t be happier with the results! The attic is extremely tight with no floorboards, so the team had to crawl on a cross beam to get the job done. It was hard work, but their dedication and efficiency truly shone through. Not only was their work of excellent quality, but the price was also the most affordable option we found. I was so impressed that I even went up in the attic myself to see their progress. Highly recommended for anyone in need of top-notch insulation services! Some before and after photos.

We had a wonderful experience from start to finish. Matt walked us through all of our options to insulate our 1978 home, and shared the pros and cons of each application. We felt confident moving forward with the care and attention he took explaining the process and how it would benefit us in the wonder and summers. The crew, Will and Timmy, were fabulous as well! They were able to remove the old insulation from our attic and prep one day, then come the next to spray. Will carefully remove explained a few areas we might have expansion foam showing through, and how we could address them. In the end, he meticulously sprayed to ensure we had maximum coverage but minimal overspray or expansion. Will and Timmy were fantastic to have at our home, and did an incredible job prepping and cleaning after they were done. I would absolutely recommend this crew to any of my family or friends with full confidence that the job would be top notch.

Aaron Shepherd★★★★★10 months ago

They were great from start to finish! Met them at the Home Show, was able to get a quote, we agreed on the price, and they were able to get the job done quickly. They were prompt, courteous and very attentive to special requests I had to skip certain sections, etc. They cleaned up and the spray foam looks great.

Sonia Carmona★★★★★3 years ago

Incredible customer service and attention to detail. HIGHLY recommend and will definitely use again. They were great at communicating and were incredibly fast. Building my dream home off the grid in the middle of the desert and they had no problem coming out to get the job done. On top of that they had the best price in the state. I tried multiple companies and they either wouldn’t come out or charged an insane amount. 10/10 recommend!

I couldn’t be happier with the service I received from Phoenix Insulation and Orlando! From the very beginning, communication was excellent. Orlando was incredibly responsive and made sure I was informed every step of the way. The team showed up and delivered top-notch results in no time. The quality of the insulation job was outstanding, and the price was more than fair for the level of service and professionalism I received. It’s rare to find a company that delivers on speed, quality, and value all at once, but Phoenix Insulation does exactly that. Highly recommended! If you’re looking for insulation done right, this is the team to call.

nancy lulick★★★★★a year ago

I saw their team working on one of my neighbors house down the street. Stoped and got there number as we were wanting to replace our insulation. Orlando came out and gave us a quote and we then set up a time for installation. They came out with a full crew to take out the fiberglass batting we had. And the next day they came in and blew in the foam insulation. That took all day for that one as it is a lot of work and material. We are very happy with the work they did. They came on time and they were very respectful for us and our neighbors as it was early in the morning. Very polite and professional. I would highly recommend this company. They do great work and they do a clean up after they are done. Very polite and friendly. That’s hard to find these days. Thank you Orlando and team.

The main reason I came back to Arizona was because I found a good company to do the spray foam insulation on the underside of the camper. I have to say I was impressed with Barrier Insulation & Energy, Glendale, AZ! They arrived on time, did a very thorough job prepping and protecting the area, completed the job as detailed and cleaned up like they were never here!! Matt and Braedon were awesome, knowledgeable, professionals. Great job guys!! I am super excited and happy about the new insulation under the camper to help reduce hot/cold transfer as well as to keep out any unwanted critters!

Dennis West★★★★★2 years ago

Very good experience. The sales staff made an appointment and actually showed up early after a courtesy call. They scheduled the job but we’re a day late because of equipment problems. During the delay, Fabian (the Forman) kept in contact with me every step of the way. I received 2 phone calls from management regarding the scheduling that was set up the next day. Fabian showed up on time and did a fabulous job. I really like the communication and the professionalism of this company. If you don’t use them, you are using the wrong company!

Tracie Gregg★★★★★2 years ago

I called Barrier installation because I had a 20+ year old Quansett hut that was leaking like a sieve they quickly got me on the schedule, the driver such a hard worker and a professional guy works so hard all day I did take two days to complete this job but it was a pretty big job. carefully wrapped things that shouldnt have product on it... they made sure that every bolt and seam had been covered to stop the leaking. it wasn’t long after the building had been sealed that we got several downpour rains. it absolutely worked. we also noticed a nice side effect that it made the building cooler inside. i’m excited to have added another 15 to 20 years on this already old building.

If you like to wait for contractors to show up all day without communicating to the customer at all, this is your business. This company has not showed up 3 times after scheduling times to do the work and then showed up unannounced wanting to do the work but we we’re leaving out of town. Plan on taking a lot of time off work if you’re planning to use them. Obviously the customer is not a priority to the company, horrible company not sure why anyone would recommend this company. Thanks for wasting my time off work.

Frequently Asked Questions — Spray Foam Insulation in Gilbert

These are the questions Gilbert 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 16 verified Gilbert contractors above for exact quotes.

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