Healthy Home Restoration was established in Cary NC in 2004. HHR has specialized in solving complex problems in crawlspaces related to humidity, pest and mold and is considered the top company in the Triangle area for crawlspace problem resolution and energy evaluation/improvements. Over time sealed and conditioned crawlspaces became the preferred method for constructing crawlspaces under homes. The process of conditioning a crawlspace is so successful it created an entire new industry. As a leader in the industry we pride ourselves in providing a large variety of products to fit our clients individual needs. We will never be a company that supplies only one solution with one product for every need. We constantly work with manufactures and suppliers to provide the best and most cost effective products available. *Free evaluations and inspections when related to emergency claims or water proofing/encapsulation. Services for general inspection of the home when related to mold, odor, suspected moisture issues, and energy audits will have a minimum service fee charged depending on the situation. Real Estate transaction discounts apply.***Does not offer full home inspections and pest control services.***

"I recently had "out of control" mold issues in the furnace room in my basement. My son and I were both suffering respiratory issues, so it had to be resolved. I brought in a company to test for mold, and ended up hiring them for remediation. When it came to "What do I do now to prevent this in the future?" they were not able to help me. After a search through ND, I came up with the names of several companies, and had all 4 out for a quote. Each person who came told me something different, some of them completely contradictory. (Ex: "There's standing water in that space" vs. "There's no water problem there, it's completely dry" given two days apart.) I came back to ND and did some more searching. This time I noticed one company came up with glowing recommendations over and over again - Healthy Home Restoration. Dennis, the owner, has a real understanding of indoor air quality issues (finally!) and came up with a proposal to encapsulate the space, add some ductwork into the unfinished workspace and put dehumidifiers in both the furnace area and workroom. (Rest of the basement is finished, with standard HVAC duct work.) The team came out and did a fantastic job. I highly recommend them! Had I known they could have done the entire job, including the part the first company did to remediate the problem, I would have hired them first. They are the best of the best!"

FAQs for radon gas testing projects in Smithfield, NC

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
