"I had a Wind Mitigation Inspection performed on my roof. My inspector was Darius Woods. He was punctual, polite, respectful of me and my property, he maintained great communication from the moment the appointment was set all the way up to an hour before the appointment. I can’t yet speak on communication after inspection, only because he literally just left my house 10 mins ago, but he did give me ample opportunities to ask questions and made sure I was happy with the inspection before he left. He also told me if I did have any questions afterwards, that I could contact him, and he provided his cell number along with his business card. He held true to his promise of sending the report before he left my property. If I ever have to have another house or roof inspection, I will definitely choose Webb Property Inspections and hope that they send Darius again!"

Radon Detection and Reduction questions, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.
