"Today I had Coit out to evaluate my air duct system with a new service they offer called aero seal. My home was built in 1986 and I wanted to see if I could perhaps improve the efficiency of our home, especially with the latest SRP rate increase. Rick and Wyattdid a great job explaining the testing process, and once the system was set up and connected to the computer program, we found our system was leaking 5.5 % into our atic. After the aeroseal process, they got that number down to 0.6 %! An 88.7 % improvement. I'm so happy I had this done, and I'm quite certain it will help mitigate any cooling loss in the summer. The crew was an absolute pleasure to work with and super professional. Even my crazy dog liked them!Thank you both so very much."

"GPS did an amazing job, start to finish. I can't say enough good things about Rudy and Kimberly, who were my main points of contact. They are professional, and always followed through. If something wasn't perfect or the way I wanted, they changed/fixed it without hesitation. Thank you for everything."

"The testing went very well. Unfortunately due to mistakes that we made BEFORE we engaged them, the clean up and testing were both more complicated than they typically would have been. The EA people worked with us to clearly explain our options and complete their work in a timely fashion. They timing and scheduling were critical for us because of a hospital stay my mother in law was having. We were very pleased both with the quality of their work and their flexibility in working around our scheduling constraints"

"***STAY AWAY*** They should remove the word "Solutions" from their name. That is far from what they provide. I started the process with Arizona Foundation "solutions" back in May of 2021 to fix a retaining wall/foundation. After meeting with the sales person they did let me know that they can proceed with engineering the "solution". After about 30 days I met with the sales person again so he could present the "solution" and take a deposit. I agreed to the option they offered and they stated I would be on the calendar to be completed before December 2021. During the permitting process there were items that came up that were needed from me directly by the county. These items were provided. After these items were provided I had not been contacted by anyone at the company to schedule the repair. At at the same time I was told by the county that Arizona Foundation "Solutions" was needing more engineering from me to complete the job. Obviously this was concerning as I should have heard about this directly from the company I was spending ten's of thousands of dollars with. However it was crickets. After reaching out to the sales person by call, text, email with no response before the holidays, I gave him the benefit of the doubt and waited until after the holidays and tried again with no avail. I then was put in contact with the "Area Sales Manager" whom after a week reviewed everything and let me now that the project they had in their hands for 7-8 months now was unfortunately out of scope for their company to complete and said they would be refunding me my deposit. I questioned how was this job reviewed and drawn out by an engineer and yet its somehow not able to be completed by them? Another week went by and the same manager contacting me and let me know that the owner reviewed and said they would solve this and get the job completed. I mistrustfully agreed for them to continue. After waiting another 2 weeks with no communication, I reached back out only to find out they were wrong and actually could not come up with a "solution" and would be refunding me my deposit (again). I waited another 2 weeks for my check to come in the mail and then called again to now find out they sent the check to a wrong address and would need to cancel that check and send out another. I asked for them overnight the check for my inconvenience and the refused to as this was an "additional cost that had to be approved". Throughout the most recent 2 months I tried to get the owners (Bob Brown) attention by phone/email to discuss my entire situation and was told he was in "meetings" 10/10 times I called. I was FINALLY able to get him to call back once I called every hour on the hour same day. As I expressed to the owner, the incompetency and ignorance starts at the top at his company. Not only was the communication poor at best during my dealings, the fact that an apologize nor any remorse was expressed on how my customer service experience was. A few key items to any contracting/construction work is setting expectations, communication, and follow through. NONE of which was provided by Arizona Foundation "Solutions". This type of work is extremely costly and any company completing it should be handling their customers with at least some respect while they spend a price of a new car or part of a college tuition on."
Underpinning Installation System Down in Gilbert, Arizona
Piers Installation at Gilbert, AZ
The moisture vacuum helps pull all the moisture particles once they get evaporated since PVC pipes got installed beneath the house foundation blowing hot air into the most affected area.
After digging the hole, a moisture sensor gets installed to send signals to the rest of the system with the purpose of calculating the moisture level in the soil.
The answer is different for every homeowner since every house is distinct and is located in diverse places with different factors. However, generally speaking, our foundation repair team drills each pier from 7 to 10 feet until reaching the strata layer to provide a solid and strong stable foundation support.

FAQs for radon gas testing projects in Mesa, AZ

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
