Signs it's time to call

  • Your water bill jumped without a change in household use
  • You hear water running when every fixture is off
  • Warm or damp spots appear on a floor
  • Stains, bubbling paint or soft drywall on a wall or ceiling
  • A musty smell in a room, closet or basement
  • The water meter dial moves with all fixtures closed

Modern diagnostics, minimal demolition

Guesswork means opening walls until water turns up. We locate first so the repair opening is small and deliberate.

You will know what we found and where before we cut anything.

Why hidden leaks matter in New Hampshire homes

Slow leaks in unheated crawl spaces and exterior walls tend to worsen through winter, and moisture in framing invites mold. Finding one early is far cheaper than repairing what it damaged.

Water Leak Detection FAQs

Can you find a leak without tearing out walls?
In most cases, yes. Detection equipment narrows the location so any opening we make is small and targeted.
Do you repair the leak too?
Yes. We locate and repair, so you are not coordinating two contractors.
