"The tester was well versed in this area even showing the areas that were high in moisture. Very friendly and informative as well as professional. Made me comfortable with the experience she had. When the owner and maintenance worker failed she made me comfortable. Fae who had the credentials as well experience explained everything in detail. Definitely use Fae!!!"

"David, Veronica and Maria we're pleasant to work with, Upfront and direct with all Communication. They also recommended a Clearance Testing Facility which was great, they made the Clearance appointment for me and the company called to schedule. David and his team where very profession, I've dealt with quite a few contractors and project managers and they did a fantastic job. David gave me his word that it will pass, and it did due to his expertise, knowledge and his Team. I thought his pricing was extremely fair as I have dealt with this problem in another area in the household due to lack of engineering integrity, I would definitely recommend AM:PM Restorations & Construction Inc. to friends and family. Don't hesitate to call and have them give you a quote."

"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."

"EVERYTHING WENT GREAT. DOV, MY CONTACT PERSON, WORKED WITH ME ON THE TIMING (ALLOWING ME TO PUSH OFF PROJECT FOR A MONTH) AND THE PRICING.  THE GUYS GOT STARTED WHEN THEY SAID THEY WOULD.  THEY CLEANED UP AT THE END OF EVERYDAY.  THE PROJECT MANAGER HAD THE INSPECTIONS SCHEDULE TIMELY AND THERE WAS LITTLE TO NO DOWNTIME. I WAS REALLY UNSURE, BUT THEY MADE EVERYTHING QUICK AND PAINLESS.  THANK YOU EVERYONE."

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Yes, many systems include warranties for performance. Confirm terms with your installer.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.
