Stop Water Damage Early
Leak Detection & Repair
A hidden leak can silently destroy walls, floors, and foundations for months before you notice. Darwyn's Plumbing uses advanced detection equipment to find leaks behind walls, under slabs, and underground — then fix them right.
Our Leak Detection & Repair Services
Visible Leak Repair
Dripping faucets, leaky toilets, running supply lines, and burst pipes repaired fast with flat-rate pricing. We carry common repair parts on every truck.
Thermal Imaging Detection
Infrared cameras detect temperature differences caused by hidden moisture behind walls and ceilings — without cutting drywall until we know exactly where to look.
Acoustic Leak Detection
Electronic listening devices amplify the sound of water escaping under pressure through pipes buried in concrete slabs or underground supply lines.
Slab Leak Repair
Pipes running beneath concrete slabs can develop pinhole leaks from corrosion or shifting soil. We locate and repair slab leaks with minimal concrete removal.
Repiping Services
Old corroded galvanized or polybutylene pipes that leak chronically? We repipe entire homes or sections using modern copper or PEX piping.
Water Line Leak Repair
Leaking main water lines between the meter and your home waste water and money. We locate and repair or replace underground supply lines.
Warning Signs of a Hidden Leak
Unexplained Water Bill Spike
A sudden increase in your water bill without any change in usage is the clearest sign of a hidden leak.
Water Stains on Walls or Ceilings
Yellow or brown stains often indicate a slow leak from a pipe above or inside the wall.
Mold or Mildew Odor
Musty smells in areas with no obvious moisture source — inside closets, behind walls — indicate trapped moisture from a leak.
Unusually Green Lawn Patch
A spot in your yard that's always lush and green even in dry weather often sits directly over a leaking underground pipe.
Sound of Running Water
Hearing water when everything is off? That pressure escaping has to go somewhere.
Buckled Floors or Warped Walls
Moisture from a nearby leak causes wood floors and drywall to swell, buckle, or pull away from baseboards.
