We are a full service property maintenance company. In addition we complete demos and complete remodels/builds as well.

"The work was top-notch, but their internal and customer-facing communication is weak. 90% of the job was as expected, but the last two items (shower doors) were installed without us approving the particular door. The owner will say they were approved, but that's not the case. One door we never saw pictures of at all, and for the other we got two cellphone pics of a computer screen saying "this is what we typically install." A month later that ultra-modern looking door was on the wall in my old farmhouse. Complaints on my part were met with threats and bullying until I paid the full balance. I finally decided it was worth missing out on the shower door to get rid of the guy. In the process of the job, I got emails from one person in the company about things that had already been decided by someone else, so it was obvious that the internal communication was weak as well. Glad I can be rid of this company. Too bad because the people they hired to do the actual work at the house were wonderful."

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.

"The self-test product was as expected. The reports require additional research to interpret and understand, so seemed more targeted at professionals."

FAQs for radon gas testing projects in Topsham, ME

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.
