"The rep came out and reviewed the areas of concern.  He gave me an estimate on the spot. The next day I decided to go with JBH and the project was scheduled for the following week.  The workers arrived within the scheduled time period and they were very pleasant to work with. They were responsive, efficient and neat. The job was completed in no time.

"The owner of the company, Phil Tantella, spent time on the phone with me giving me lots of information beyond what his scope involved. He was so helpful and knowledgeable. Working with his company was a good experience from start to finish. The process takes time, and Phil stayed in touch, keeping me up-to-date so I could move forward with other planning."

"Mike called within minutes of my search. He was able to stop by the same day and evaluate my situation. Gave me suggestions for my in-window air conditioners as well to eliminate any mold buildup. He explained the process for the next level for cleanup. Very friendly and knowledgeable. Told me upfront prices. Would highly recommend Mike and Family Home Inspection."

"David inspected a potential home I was looking to purchase and he was so thorough that by the time we were done it gave me a very clear understanding of what issues the house had, what needed fixing and what was downright dangerous. When buying a home, you need a great inspector like David because if you don't get a good inspection you run the risk of buying a big money pit. I bought a home once before but that was a joke compared to the great inspection David did. The home David inspected was a small 1200 sq. home but it was built in 1935 and so he did mention we should expect to see some things pop up. However, he went above and beyond and I am so grateful for his hard work that I will recommend him to others in the future as well and will call on him again for inspections. He also brought Alex, a septic inspector, with him who was also very thorough and very good and provided a very through report. Thank you, David, for your wonderful help! You have no idea how much I appreciate it."

Radon Detection and Reduction questions, answered by experts

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.
