We focus on diagnosing and clearing blockages in these critical drainage systems, restoring their ability to divert water away from your basement walls and foundation in Lake Oswego.
Sump Pump Installation & Repair in Lake Oswego
A dependable sump pump is crucial for preventing basement flooding, particularly in areas with high water tables or heavy rainfall. We offer professional installation of high-capacity sump pumps, including battery backup systems, to ensure continuous protection. Our technicians also provide fast repair and maintenance services for existing sump pumps, ensuring they operate effectively when you need them most.
Wall and Slab Seepage Repair in Lake Oswego
When water enters through foundation walls or the slab joint, the cause is most often surface water pooling against the house. Hillside homes can face soil movement after heavy rain, which can crack buried water and sewer lines. Dense or saturated soil can hold water near the foundation instead of letting it drain away. We seal penetrations where pipes pass through the wall and can install interior drain channels that carry seepage to a sump. We also suggest grading and gutter changes when outside water is the root cause.
Exterior Waterproofing in Lake Oswego, OR
For a more comprehensive 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. The eastern side of the state is drier, with hotter summers and colder winters that strain pipes and water heaters differently.

Water Damage Assessment in Lake Oswego, OR
Before any repair, our team performs a thorough water damage assessment to identify the source and extent of your basement leak. This includes inspecting for mold growth, structural concerns, and damaged finishes. Our comprehensive approach ensures that all related issues are addressed for a full restoration of your Lake Oswego basement.
