Water Drainage with Sump Pump and French Drain
Lake Atitlan Insulation offers advanced protection against moisture, mold, and structural damage in your home. Our system combines a French drain with a sump pump to keep your crawl space dry, safe, and healthy.
In the Seattle area, excessive rain and sloped terrain can easily cause water to accumulate in crawl spaces. This leads to moisture, mold, unpleasant odors, wood damage, pest infestations, and reduced home energy efficiency. A French drain system along with a sump pump is the most effective solution to prevent costly damage and prolong the life of your home.

How the System Works: French Drain + Sump Pump
Interior French Drain
A perimeter trench is installed inside the crawl space. A perforated pipe covered with gravel and a geotextile filter then collects and redirects water, preventing accumulation and maintaining a constant flow for drainage.
Sump Pump
A submersible pump is installed in a collection pit. The pump automatically expels water to the exterior of the house. We offer options with battery backup for emergencies and a check valve for maximum security. Silent, high-performance models guarantee reliable operation.
