There isn’t a single “average” price to fix a leaking pipe. Your cost depends on where the leak is (fixture, crawl space, slab, underground), access conditions, pipe material, and the repair method. We diagnose with digital camera inspection, hydrostatic testing, low-pressure air testing, and underground leak detection, then present options with an Upfront No Surprise Price. Repairs may be a spot fix, PEX repiping for domestic water lines, or no-dig trenchless water/sewer repair. Work includes a written guarantee. We serve Redmond, Everett, and Seattle.

Slab leak detection and repair cost is confirmed after an on-site evaluation, with Apollo Plumbing providing an Upfront No Surprise Price before work begins. The biggest driver is how the leak is pinpointed through concrete and which repair method your home needs. Some underground leaks can be fixed with trenchless techniques that avoid tearing up your yard, which changes the total project cost. We regularly resolve slab and underground leaks in the Marysville area. All work is backed by a written guarantee. Current offer: $55 OFF Underground Leak Detection Services.
Price typically varies based on:
- Access and exact leak location (under slab, near a foundation wall, or at the service line)
- Detection methods used (digital camera inspection, hydrostatic testing, underground leak detection)
- Scope of repair (spot repair vs PEX repiping for aging domestic lines)
- Surface restoration needs after repair (concrete openings vs trenchless line replacement)
If you suspect an active slab leak, shut off the main water valve and schedule an evaluation to limit damage. <br/> Updated: 2026-03-10 <br/> Need help in Marysville, WA? Call (425) 387-1507 or book online.

To find a water leak inside a wall or ceiling, confirm moisture, narrow the zone, and verify if a pressurized line is losing water before opening the surface. Most hidden leaks come from water supply lines or fittings that slowly seep and track along framing. When quick checks aren’t conclusive, Apollo Plumbing uses camera inspection and pressure-based methods (pneumatic test balls, low-pressure air, hydrostatic testing) to pinpoint the source with minimal removal. Our team handles this type of detection and repair across the Seattle area daily. Small, isolated leaks are usually repairable; widespread corrosion or multiple leaks may point to targeted PEX repiping.
Try these quick checks before you cut into drywall:
- Watch the water meter after shutting all fixtures to confirm a pressure-side leak.
- Listen for hissing or dripping and feel for warm spots that hint at a hot-water line.
- Trace the wettest area with a dry paper towel along baseboards and seams.
- If water is active, close the main valve and protect ceilings and electronics below.
If a ceiling starts to bow or water is near electrical, shut power to that area and call a licensed plumber. <br/> Updated: 2026-04-30 <br/> Need help in Seattle, WA? Call (425) 387-1507 or book online. "Geoff came out the same day, repaired the leak with an hour!" — Jeremy F.

You can try a short-term DIY fix on a small, threaded joint drip by gently retightening or using temporary sealant, but lasting repairs usually require replacing worn parts or sections of pipe. We find the true source first (digital camera inspection, leakage testing, hydrostatic testing), then repair properly—anything from fixture repairs to PEX repiping or trenchless solutions. This helps prevent hidden damage in places like walls, slabs, or crawl spaces in Seattle and Everett.
Quick checks:
- Shut off water to the line.
- Dry the joint and inspect.
- Do not overtighten.
- Call if the leak returns or you see corrosion. <br/>
