Leak Detection & Repair
Leaks range from an obvious drip under a sink to a slow hidden leak inside a wall. Left alone, small leaks can turn into structural damage, mould, and much larger repair bills. We locate the source and explain the repair options on site before work begins.
No guessed prices over the phone. A licensed plumber inspects the problem, explains your repair options, and confirms the price with you before any approved work starts.

FAQs about leak detection & repair
How do you find a leak inside a wall without tearing everything open?
We start with the smallest reasonable access point after locating the leak by moisture, sound, and pressure testing. Only what's necessary gets opened.
My water bill jumped, could it be a hidden leak?
Possibly. We can help isolate whether the source is a fixture, a supply line, or something else, and explain the repair options on site.
Do you repair leaks in copper and PEX?
Yes. Both copper and PEX systems are common in this area and both are repairable.
Will you repair drywall and finishes after the fix?
We focus on the plumbing repair itself. Drywall and finish repair is usually handled separately, and we're happy to explain what's involved.
