"Chuck and Noah, are amazing to work with. They communicate extremely well and are honest. They did a home inspection Saturday morning for me. Thankfully I asked them to do a full septic inspection, not just a dye test. They found the septic system, needing major work. To the point, my bank won't approve the loan. the house failed before they even got inside it. When trying to explain to the home own, (who is also the listing agent) what was wrong, and why it needed to be fixed. All this lady did was rudely speaking over him, to the point she was mad at him for finding it. She would ask why it failed and as soon as chuck would begin to explain, she would start yelling over him, how it was fine. She must of ask half a dozen times for him to explain, for her to start arguing as soon as he spoke. I don't know how Chuck was able to be so calm and professional. I would have hit the lady, getting in my face like that. Chuck, was instead calm,kind and professional. "

After washing the windows with Windex and wiping everything down with a dry towel, the car was free from odor and looked and smelled clean and fresh! Fantastic Products!!!"

"Assessment done for mold found near crawl space. Gary was fabulously helpful, even helped move some boxes out of the closet where the crawl space entrance is. He took the time to explain everything, had a sensor that can detect moisture through the wall (drywall in this case), had helpful suggestions, was very thorough in checking the nearby rooms and garage with the sensor. And he's just a nice man, a mensch. I would absolutely hire him again if needed. Thank you, Gary!"

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

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.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.
