What Kent Leaks Look Like

Where Kent Homes Leak

Kent leaks fit a few common patterns. East Hill subdivision two-story homes generate ceiling-leak calls when a second-floor bathroom supply, toilet supply, or shower pan fails. Older valley-floor downtown homes leak at galvanized supply coupling joints. West Hill mid-century homes show pinhole copper. Slab leaks come up in some Kent builds.

Common Kent leak scenarios

  • Ceiling stain below second-story bath in East Hill homes: Usually a supply, toilet supply, or shower pan failure on the upper floor.
  • Failing galvanized at couplings in valley homes: Pre-1970 homes leak at the coupling joints first.
  • Pinhole copper in West Hill mid-century homes: A drip in a wall or ceiling stain.
  • Water bill spike with no obvious cause: Often a service-line leak, running toilet, or hidden supply leak.
  • Crawlspace leaks in older homes: Aging copper or galvanized supply.

FAQs

Common Questions: Leak Detection in Kent

Can you find the leak without opening the wall in my Kent home?

Usually yes. Leak detection reduces unnecessary demolition.

My East Hill ceiling has a stain under the upstairs bath. What's likely?

Most often a toilet supply, shower pan, or sink supply on the second floor. We isolate before any drywall opens.

Do you handle slab leaks in Kent?

Yes. Slab leaks are diagnosed with acoustic and thermal tools.

Will you patch the wall after the leak is fixed?

We open cleanly. Drywall repair, texture, paint, and finish work are by others unless those steps are written into the scope.

My water bill is high. Can you find why?

Yes. Bill spikes usually trace back to a service-line leak, running toilet, or hidden supply leak.
