"I’d like to warn you all about Octagon Construction and the horrible experience we have had with them. Before Thanksgiving, the machine overflowed. For hours. Filled my basement. Serv Pro came and tested everything and determined our floors needed to come out in the basement, kitchen, hall, bathroom and laundry room. Octagon Construction told us we were next on the list. We moved into a hotel. They told us it would be done in a week . They came for a few days and then no one showed up. For days. Mike reached out to them & they said they went to do some other job. Then they told us it would be another week. And then another week. And then another week. When we finally came home after a month + my house was completely filthy. Every nook, every cranny, under several inches of dust, including upstairs, in my bedroom, in my drawers. Everywhere. I took time off from work and started cleaning. Every single thing I own. My previously freshly painted walls now had stuff smeared on them that wouldn’t come off. The dust isn’t regular dust but more like some dust and goo combo that isn’t easy to clean off. Mike had to repaint the walls. But worse, our floor looked like s***. There were tiles popping up everywhere. There were huge gaps around the edge & the trim. The insurance guy came. A tile expert came. And then Octagon informed us we would have to move back to the hotel. I lost it because I’d just spent several days cleaning from the time I got up until the time I went to bed. They promised that this time they would clean. They said they would be done Sunday. When I finally got home Tuesday my couch was IN PIECES in the middle of the living room and s*** was in piles. And the dust was back on everything again and in every nook and cranny. My basement is covered in the dust and wood shavings. My refrigerator is dented. My brand new stool has a hole on it. My weights are covered in thinsulate. There are dings in the walls, paint on the floor, scratches on my fridge and walls. A plant is just entirely missing. I sent pictures to Alex, the schmuck who’s the contact at Octagon. This morning , after promising they would clean everything when he told us we had to move back out, I sent pictures when I got home, I get this message “We have met and exceeded our contractual obligations for our agreed upon scope of work. You will be receiving our invoice for the balance due. “"

It’s a fact: Today’s homes are so well insulated that they trap humidity and pollutants indoors. Result: Over 50% of homes show visible signs of humidity. However, it is possible to breathe fresh air inside as if you were outside and fully enjoy your home. According to specialists, central ventilation and filtration effectively eliminate airborne pollutants and excess humidity, thereby protecting your family’s health and the structure of your house.

Radon gas abatements FAQs

You need a professional radon test to determine if radon is present in your home or water. A qualified radon inspector can provide accurate measurements, costing between $150 and $800. This information helps you decide on the necessary steps to remove radon from your home when you hire a professional radon mitigation company.

Radon inspectors and radon treatment professionals have distinct roles. Inspectors measure radon levels and assess your home's risk, while treatment professionals install systems that reduce radon concentrations. In some cases, a single expert may perform both functions; however, each responsibility requires specific expertise to ensure accurate testing and safe system installation.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reduce radon levels reliably.
