why a single radon test can't protect your home

At a single home in Blowing Rock, one radon monitor took 1,440 radon readings over a recent 60-day period.

There were two-day windows where a traditional short-term test would have returned a reading as low as 12.1 pCi/L (3x the EPA recommended action level). But there were also two-day windows where levels hit 95.2 pCi/L (24x the action level), driven by dropping barometric pressure and temperature differentials, pulling radon up in ways a point-in-time test would never capture.

A short-term test doesn't measure the radon level you are experiencing. It measures your radon level on the days you happened to test. Depending on when you placed that test kit, you could walk away falsely reassured.

Three pictures showing different ways plumbing can be stressed or fail due to water pressure fluctuations

is your water pressure silently damaging your pipes and appliances?

One homeowner had replaced their dishwasher, a bathroom faucet set, and several toilet flush valves over the same two-year stretch. Different brands, different failures, same house. They chalked it up to bad luck…or maybe just the hard water.

After installing continuous water pressure logging, they were pointed to a different culprit. Their incoming supply pressure was averaging 96 psi, well above the 80 psi threshold that most appliance manufacturers set as the maximum in their warranty terms.

frost quakes: felt and heard during a recent ice storm

If you've were recently jolted awake in the middle of a cold winter night by what sounded like a bowling ball dropping through your ceiling, or a rifle shot somewhere in the walls — you may have experienced a frost quake. We know, because we caught one here in Blowing Rock.

In January 2026, the same storm rolling through caused residents across Middle Tennessee to flood local weather services with frantic reports: mysterious booms shaking their houses, trees they assumed had fallen, sounds they couldn't explain. The culprit wasn't a gas line, a fallen limb, or anything structural. It was the ground itself.
