Exterior Waterproofing Solutions in Burien, WA

For comprehensive basement leak prevention, exterior waterproofing involves excavating around your foundation and applying waterproof membranes or coatings. This creates a robust barrier against moisture intrusion from the outside. While more involved, this method offers superior long-term protection against water damage, especially for older homes in Burien.

Sump Pump Repair and Installation in Burien, WA

Many basements rely on a sump pit to handle storm runoff and groundwater. River flooding and saturated ground can push water back through sewer lines, so backwater valves and sump pumps are worth considering. Pumps from brands like Zoeller, Liberty and Wayne fail most often from a stuck float or a burned-out motor after sitting idle for months. We repair or replace the pump, check the check valve and route the discharge well away from the foundation. A battery backup is worth considering because big storms often knock out power.

Hydrostatic Pressure Management in Burien, WA

Heavy rain can lead to significant hydrostatic pressure against basement walls, forcing water through concrete. River flooding and saturated ground can push water back through sewer lines, so backwater valves and sump pumps are worth considering. FHN Plumbing installs interior and exterior drainage systems, including French drains and weeping tile systems, to alleviate this pressure. We also install sump pump systems to efficiently remove collected water, keeping your basement dry.

Waterproofing for Older Washington Homes in Burien, WA

Many older homes in Burien and across Washington were not built with modern waterproofing techniques, making them more vulnerable to basement leaks. Newer homes in Burien usually use PEX supply lines, and many older houses have been partially repiped over the years. FHN Plumbing focuses on retrofitting older foundations with current solutions, addressing issues like failing mortar, porous concrete, and inadequate drainage. We preserve the integrity of historic structures while providing modern protection.

Exterior Waterproofing in Burien, WA

For a more complete solution, we offer exterior waterproofing, which involves excavating around your foundation, applying a waterproof membrane, and installing drainage boards. This method creates an impermeable barrier on the outside of your basement walls, providing superior protection against water intrusion. Washington has two very different climates, with long, wet and mild seasons in the west and hot, dry summers and cold winters in the east.

Floor Drain and Backwater Valve Repair in Burien

A basement floor drain that backs up during heavy use or a storm typically points to a blockage or a failed trap. We clear the drain, check the line to the main sewer and replace cracked traps and covers. Installing a backwater valve stops sewage from pushing back into the basement if the main line surcharges. We set the valve where it can be serviced easily.

Foundation Crack Repair in Burien

Foundation cracks are a common entry point for basement water leaks, especially in homes built on soil that swells and shrinks. Steep slopes and wet soils can shift over time, which stresses buried sewer and water lines and sometimes separates joints. We utilize epoxy and polyurethane injection techniques to seal these cracks, preventing water infiltration and reinforcing your foundation. Our methods are matched to the specific type and size of the crack, ensuring a durable repair.
