Keyport: There's a Warm Spot on My Floor
A patch of floor that's warm to the touch, often with the water heater running more than it should, is a hot supply line leaking under the slab or in the subfloor.

Keyport homeowners describe warm spot on the floor the same way: a damp foundation nobody questioned, sometimes a bill that climbs quietly, and no idea where to look. We do. A clay layer under the village shelf, 1920s galvanized under village foundations and shoreline lots at Virginia Point tell us where to start, and thermal imaging camera tells us where to stop.
Why this happens in Keyport
In Keyport we check radiant heat, if the home has it before anything else, because a bill that climbs quietly is how it shows up here. A radiant floor zone that's stuck on. A clay layer under the village shelf makes the signs misleading, so we confirm rather than assume.
Next: a hot supply line leaking under the slab. Copper in direct contact with concrete or aggressive fill pinholes over time. With beach deposits at Virginia Point under small, tightly packed village lots, the symptoms can look identical to the first cause, which is why the meter test and the locate matter.
Don't overlook a hot line leaking under a crawlspace floor. A pinhole or failed fitting under the subfloor warms the boards above. On Keyport properties from a village that grew up with the torpedo station after 1914 it comes up more than you'd think.
Before you call
The shoreline clay keeps the ground damp enough that nobody notices a wet spot, so the first sign is pressure or a bill.
Do this before anyone digs damp shoreline ground on Liberty Bay in Keyport: do the meter test with everything closed. Close every fixture and watch the water heater: does it fire with nothing running? It takes minutes and it tells us whether the problem is on short runs on the peninsula grid or inside the house.
What happens next
The repair side is interior water leak detection. On larger parcels along Keyport Road that means isolate hot and cold, then trace and listen in till on the Keyport Road approaches where the problem actually is, then thermal and moisture. If what we expose is copper from the Navy station's later decades at the end of its life, we say so with the pipe in your hand.
