We are a full service licensed home inspection company in Massachusetts we have been in business since 1996. Owner operated, no subcontractors. Mass. Home inspectors license #153, Certified ASHI member # 2552071(American Society of Home Inspectors) certified/licensed Massachusetts pest inspector WDI registry certified. Fees quoted are based on multi factors, including property size, age and type of property. Email [email protected]

"Set up an appointment for an initial 10 minute phone call to talk about what we wanted. Tom ended up spending 25 minutes with us and answered a ton of questions. We subsequently set up an appointment for an initial pre-build inspection of the foundation, framing, roof, and windows. Tom was very thorough. He obviously knew his stuff. Pointed out several items that needed addressing before the insulation and walls went up. Couldn’t be happier with the amount of time he spent, how thorough he was and how much he listened to all my stupid questions and answered them in a language that I could understand. We will have him back before the next phase starts and probably a couple more times before we close. Anyone building a house or buying a new home would be wise to hire Tom. Great piece of mind and cheap insurance. Plus, he’s a really nice guy to boot."

We are Independent Home Inspectors, providing valuable inspection information conveyed through a detailed report with photos, since 1983. Our home inspections reveal the condition of structural, electrical, heating, cooling, plumbing, roofing, chimneys, fireplaces, windows, doors, siding and many other home components. Price shopping home inspectors? Have you checked if your potential home inspector:

"Evan was awesome. He was quick to respond when I called and made schedule adjustments to fit us in on the only day and time we had available. He was easy to communicate with whether it was phone call text or email. On the day of the inspection he was there early to do the exterior and went over everything with me outside before the realtors got there. When we were inside he was meticulous and explained things to me every step of the way. You could tell he cares about what he does and I felt like he was looking out for us as the buyers. He was a funny guy who you want to have a beer with after and made the experience very pleasant. I would definitely recommend Evan and would use him again in the future. I think his pricing is fair and while it may look like we paid more than others it’s because we added a radon test and water quality test."

Radon Detection and Reduction questions, answered by experts

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

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.
