Very friendly company, showed up when they said they would and were willing to finish up there day way out northwest Peoria. Nick the owner did the work and we couldn’t be happier with the result. I knew right away Nick was the right guy for the job and the cost was reasonable so I hired him on the spot. If you are looking for a professional hard working company that cares about the job they do hire them as soon as possible!

I talked to other insulation contractors that tried to hard sell me on stuff I didn’t need or even want. Phoenix Family Insulation said they could do all those things, but recommended only what I needed. Came on time, went above and beyond and cleaned up after themselves. I highly recommend calling them first to save time!

Insulation Commandos was terrific throughout the entire process, from initial inspection to show me the age of my insulation to the removal and install of the new insulation. I’ve already seen a positive impact on my energy bill. They sent me before and after photos and the difference was noticeable. If you have an older home, I recommend contacting Insulation Commandos for a free inspection.

Had a wonderful experience with Insulation Commandos of Greater Phoenix. My request for a no-cost estimate was addressed quickly, the appt was set and Jackson arrived right on time. A thorough analysis of my attic was made, photos were taken and options were discussed. I had a lot of questions and Jackson answered every one of them. On the scheduled day, Jackson and John arrived on time to begin the work. Jackson, a master communicator, kept me apprised of their progress along the way. Jackson and John were both professional, friendly and knowledgeable. Excellent job at a reasonable price! I highly recommend this company.

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.

After researching multiple insulation companies I decided to have 4 companies come to my home and compare pricing and quality. I had a lot of mixed options and recommendations. When Green Faith Solutions came to my home they were the only ones that actually made sense and I felt comfortable with. Other companies tried to oversell me on items that I didn’t need and didn’t make sense for my home. Erik and Philip took the time to explain and be thorough and honest with me. I’ve noticed a HUGE difference in the temperatures of my home, I don’t have inconsistent temperatures in my rooms anymore, my AC unit is running a lot less, and I am a lot more comfortable in my home now. I HIGHLY recommend this company and would definitely use them again if I move to another home ! They provided before and after pictures and left my home cleaner than it was before !

Melissa Meyer★★★★★3 months ago

We’ve lived in our current home for over 15 years which we have been running our AC units between 70-75 degrees during the summer months and still not comfortable. As Green Faith Solutions was spraying our attic we could literally feel each room getting cooler. And staying cool! We are amazed how comfortable our home is now. No more avoiding certain rooms during the hottest time of the day as each room is now perfectly comfortable. We finally feel the cool breeze from our ceiling fans even after the AC has run its cycle. Philip and Eric are very professional and trustworthy. Our experience has been nothing shy of pure excellence! Couldn’t be more grateful to have found Green Faith Solutions.

Gene Dupuis★★★★★5 months ago

Phillip came and gave us a bid to get the attic insulated. They use a top grade quality insulation, Owens Corning. Phillip inspected the attic, took pictures of what was needed and gave a bid on the spot. He is a co-owner of the company. He and his assistant came when they promised to be at the house. Completed the job in just under two hours for a 2100 sq foot house. He took before and after pictures and we were really impressed. Overall, a great job done. Price was in the middle of the bids that we got, but the product used by Green Faith Solutions was much better and had a lifetime warranty. Highly recommend them if you need insulation.

Had spray foam done on a vaulted ceiling. Sent request for a quote via Home Advisor and got a call the next day. Tracie came a couple of days later and gave us an unbelievable quote! We called back 2 months later to schedule an appointment for install. They came a week later (my choice) and spent the day preparing for the spraying, spraying, and cleaning up when done. The installers were very efficient! Would highly recommend this company!

Ryan★★★★★4 years ago

Wow! Super impressed with this company and the injection foam insulation. My house is block construction with no insulation on the interior walls. I was looking for an affordable solution as the afternoon sun super heated my house. I had the injection foam done and this lowered my interior wall temperature about 8-10 degrees which makes a huge difference inside. I’ll be using them for duct sealing in the future. So hard to find quality companies but Southwest is one of those companies. Tracey-my sales rep was excellent as well. Very professional and communicative.

Bret Royle★★★★★6 years ago

We are in the middle of a remodel and our general contractor planned to install traditional pink insulation. I called Southwest InSEALators to get a quote. Tracy was able to provide a free estimate the very next day. Better was that the quoted price was cheaper than what my GC was charging for traditional insulation. Tracy proved herself to be knowledgable, dependable, helpful and honest. They did a great job and our addition retains heat and cold while blocking sound. I plan to use them to insulate the other side of our house in the future.

Willie Coffey★★★★★4 months ago

Milton was great. Texted ahead of arrival and was on time. Quote was a little higher than expected but still lowest of the three I got. And offered cash discount. We had 2400sq ft of blown in insulation to bump everything up to R-38 or better (mostly better), plus 175sq ft of batting on some bare knee walls. Milton was honest about what was needed and what wouldn’t be cost effective. Was all done in about 3.5 hours. Attached about 50 before and after pix to the invoice. I would highly recommend Izzy’s Insulation.

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.

I tried multiple companies and they either wouldn’t come out or charged an insane amount. 10/10 recommend!

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.

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.

Koala was super enjoyable during the sales visit to my house. The person was candid, relaxed and did not push anything on me. He did a thorough inspection of my attic and recommended ways for me to save money by removing heat and insulating better. I had to reschedule several times and Koala was very understanding each time. On the day of solar fans install, it went quickly and professionally. They even cleaned up nicely after themselves. They made it a point to also point out where insulation in the attic was thin, which was already discussed with the sales person. All the team at Koala is tip top. Glad we are using them.

John Fernandes★★★★★a month ago

Absolutely fantastic experience. The sales person explained everything very well and in excellent detail that made it easy to understand. He was absolutely honest about everything and did not try to upsell me by any means. The technicians that did the install were excellent communicators and were very neat and tidy. They were also absolutely on time. I liked them so much that I will absolutely hire them to do another house for us about a block away. I am very fussy and I would not hesitate to recommend this company.

Brian Rivera★★★★★9 months ago

Thermo Shield was great to work with from the initial consult through to completion. I received four quotes. Each company varied in what services they provide. Thermo Shield offered the broadest array of home efficiency services. The consultant, Caden, gave our home a thorough look and identified other ways to improve our efficiency. His focus was on recommending only those services that would return value to me, not anything and everything that would improve efficiency. Beyond that, he suggested minor improvements that a DIYer could do to save $ and I handled those on my own. The quotes and payments were all well documented using modern technology for record keeping and payment security. Not all contractors that quoted me accepted credit card payments and Thermo Shield’s quote was still very competitive for all the work done. Thermo Shield partners with APS and handles the rebate process on the customer’s behalf, reducing project cost by the available rebates. They also made me aware of available tax credits I may also qualify for. The installation crew (Pedro and Ronald) did great work. I had spray foam done in one section of the house where it made sense and blown in insulation in another. My ductwork was sealed. Knee wall insulation repaired. Access doors batted. The guys cleaned up after themselves when they were done. Looking forward to seeing the improvement to my energy bill when the valley heats up soon. I would definitely recommend them and they do offer a referral reward so hit me up if you want!

From start to finish, Thermo Shield was professional and efficient. Darwin came over to assess our attic and he clearly explained what needed to be done.

The experience with foam insulation of my garage was exceptional, and the results are unbelievable. The entire team—sales, owner, and installers—was easy to work with, professional, and applied zero pressure. The thermal performance is night and day. Even when it's scorching hot outside, the interior temperature is drastically reduced and remains manageable. My mini-split rarely runs, and when it does, it cools by 10∘F in just one hour! This efficiency is a massive improvement. A huge thank you to Dustin, the installer, who went above and beyond. He added extra insulation in corners and patched everything so cleanly that I won't need to repaint. In fact, the results were so impressive that I showed two neighbors, and they both instantly decided to foam insulate their own garages. Highest recommendation!

Rod Horne★★★★★2 months ago

From the time I called and they came out to my home for an evaluation on what I needed, was 2 days. The next week I was scheduled and the work was done in a manner of hours. I have the walls and attic of two particular rooms in my house that were on the south and west side, they were extremely hot. The day after the temperature inside those rooms was easily 15 degrees cooler. Even though the rest of the house may have been cooler because of the air conditioning, those rooms stayed much hotter. I'm grateful for Patrick and his team that came out and took care of this issue I had. I would highly recommend Kasi Home Engineers. I will be calling them to do the rest of my attic soon.

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!

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.

Frequently Asked Questions — Spray Foam Insulation in Phoenix

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