Your home is one of your biggest investments, we treat it with the same care as if it were our own.

"The company (Sean) did a pre-drywall inspection on our new home. He was particular and detailed in his inspection. He included pictures of every area that needed attention, which helped immensely. That gave the builder something to go by and me something to compare when corrected. He also had a drone so he could check the roof. After the inspection, I contacted Sean and asked if he had time to explain at 8:00pm because I had to wait until my husband was home and he accepted. On the call he took his time and explained all he found and answered all our questions. I will definitely use Sean again and refer him to others. I have several friends who are realtors and I will definitely pass his information to them. "

We lead with a promise of Trusted Five-Star Service, which means the customer experience is at the center of everything we do. Since 1958, we have been steadfast in keeping this promise and in upholding the values on which '58 Foundations was built: trust, teamwork, integrity, respect and communication.

"I contacted 3 different companies, and this is the only one that I recommend. Our salesman Kent Tysinger was wonderful. He was the only one that showed us pictures of our house underneath it. He even called me one night after his working houses to answer my question. He recommended what would work and he was correct. It took less than a week for the job to be started. Jonathan Stone & his crew came to the job site for one week. Each day Jonathan or one of his crew members would tell me what they were doing that day. When the day ended one of his crew members would come tell me that they were leaving and that they would be back the next day and they always arrived at the time that was stated. I had some concerns, and the GM manager came to my house and assisted with the issues. Also, when the job was completed, Jonathan went over all the pictures that he took of the complete job. All I can say is that this company better keep the employees that has assisted me with my job. We are so satisfied with the complete work."

Radon Detection and Reduction questions, answered by experts

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.
