Post-Tension Slab Leak Repair in Sammamish

Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs requires care and scanning to avoid hitting a cable. We use ground-penetrating radar or other scanning methods before opening the floor. When the risk is too great, rerouting the plumbing is usually the safer option.

Water Line Reroute in Sammamish

Rerouting abandons the leaking line under the foundation and runs a new line through the attic or walls. This avoids breaking concrete and removes the risk of future leaks under the slab. We typically use PEX for reroutes because it is flexible and resists corrosion. Drywall openings are kept small and neat for simple patching.

Copper Pipe Leak Repair in Sammamish, WA

Many older homes in Sammamish, WA have copper water lines beneath their foundations, which can corrode over time due to soil conditions or water chemistry. Municipal water west of the mountains in Washington is typically soft, while supplies on the drier east side tend to run harder. When these copper pipes develop pinhole leaks or cracks, they need specialized repair. Our technicians repair or replace sections of damaged copper piping, providing a durable seal that holds up to pressure and ground movement and helps prevent future leaks.

Exterior Foundation Leak Solutions in Sammamish

Many foundation leaks originate from exterior factors like poor drainage, overflowing gutters, or saturated soil. We assess your home's exterior to identify these culprits. Our solutions include grading adjustments, French drain installation, and downspout extensions to redirect water away from your foundation. Good exterior water management is key for preventing hydrostatic pressure buildup against your foundation walls in Sammamish and keeping water out.

Drain Line Leak Under Foundation in Sammamish, WA

Leaks in drain lines under the foundation can be harder to detect because they are not under constant pressure. We use camera inspection and hydrostatic testing to find cracks and separated joints. Repairs may involve tunneling, cutting the slab or pipe lining. We explain the trade-offs of each method.
