Trusted Leak Detection in Durham, NC

The most common signs are a water bill that climbs with no change in usage, the sound of running water when everything is off, a damp or discolored spot on a wall or ceiling, a warm or soft patch on the floor, a musty smell, or a water meter that keeps moving after you shut off every fixture. Any one is worth checking; several together usually mean water is escaping out of sight.

Because the most expensive leaks are the ones you cannot see. A silent toilet leak, a cracked supply line in a wall or crawlspace, or a break in the buried line to your house can waste hundreds of gallons a day without ever showing on the surface. On a tiered water rate, that extra usage also pushes you into higher-priced billing tiers, so the bill spikes harder than the gallons alone would suggest.

Not always. Water near an air handler, a furnace, or a ceiling below an attic HVAC unit is often a clogged or cracked AC condensate drain line, not a plumbing pipe. Because A/C Medic handles both HVAC and plumbing, we can tell which system the water is coming from and fix the right one in a single visit, instead of sending you to two different companies.

Some do, but they are less common here than some plumbers would suggest. Most established Triangle homes sit over crawlspaces, so hidden leaks usually turn up in crawlspace lines, behind walls, under sinks, or in the buried yard line, not under the foundation. Slab-built homes, more common in newer subdivisions, can develop true slab leaks, and we can locate and repair those too.

That is the goal. We work from the evidence in: a meter check confirms water is escaping, a pressure test narrows the zone, and isolating lines one at a time pinpoints the failing one. Only once we know where the leak is do we open the smallest access needed, then repair the line in the same visit when we can. You are not paying us to cut into drywall on a guess.

A water-line leak is pressurized clean water, so it shows up as a spiking bill, a hissing or running-water sound, a damp spot, or a meter that keeps spinning. A drain or sewer problem shows up differently: slow or gurgling drains, a sewage odor, or a patch of unusually lush grass in the yard. If it is the drain side, that is handled on our drain cleaning service. When you are not sure, we will tell you which it is.

A/C Medic quotes leak work as a flat rate, and you approve the full price before any work starts. Simple, accessible leaks are quoted on the spot. Leaks that need more diagnosis, like a buried yard line or a leak inside a wall, are quoted after a quick on-site assessment, so the number you hear is the number you pay.
