The Problem

Is Water Taking Over Your Property?

Residing in the Pacific Northwest implies that one has to deal with rain. However, when the rain moves to your yard, into your basement, or is eating away at your foundation, it is not just an inconvenience—it is a risk to the structural integrity of your home.

The Consequences

Choked gutters, improper grading, and high water tables can reduce your house to a swamp, leading to the growth of molds, torn foundations, and un-utilisable exteriors.

The Solution

Advanced Waterproofing’s French Drains

The best solution for surface and groundwater is a tested French drain. We do not simply dig a trench and fill it with gravel. We create individual drainage systems that deal with the soil and topography characteristics of your specific property. The gathered water is directed to a safe discharge point, eliminating the possibility of flooding and protecting your landscaping.

FAQ: French Drains

Common questions about yard drainage and water diversion.

What is the difference between a French drain and a regular gutter downspout extension?

While downspout extensions manage water coming off your roof, a French drain handles groundwater. If your basement floor is leaking or water is accumulating in the middle of your yard, that is groundwater. A French drain diverts it before it gets to your home or pools in your lawn.

How long does a professionally installed French drain last?

When installed correctly with high-quality materials, a French drain can last 30 to 40 years. The trick is using a high-quality filter cloth to avoid clogging the pipe with sediment, which is standard practice in our work at Advanced Waterproofing.

Do I need a French drain inside my basement or outside?

It depends on the water source. If water enters through the cove joint (where the wall intersects the floor), an interior drain system (perimeter drain) is viable. For flooded yards or water flowing towards the foundation, an exterior French drain is the optimal preventive measure. We assess both during your free estimate.

How much does French drain installation in SW Washington cost?

The cost varies based on the length of the drain, depth of the trench, and accessibility of your yard. As a local family-owned enterprise serving Longview, Kelso, Castle Rock, and Toledo, we offer competitive and transparent prices. Call 360-846-8519 for a precise, free on-site estimate.
