Professional Yard Drainage Services
Standing water and soggy lawns are more than just an eyesore—they are a threat to your property’s structural integrity. At Basement Expert, we design and install custom yard drainage solutions to move water away from your home safely and efficiently.

French Drain Installation
A poorly draining yard can quickly lead to an unusable lawn and compromised foundations. We specialize in comprehensive French drain systems designed to capture and redirect subsurface groundwater.
-
Yard French drains: Ideal for eliminating soggy spots in your lawn.
-
Foundation French drains: Crucial for keeping hydrostatic pressure off your basement walls.
-
Curtain drains: Perfect for intercepting groundwater before it reaches your property line.
Catch Basins & Channel Drains
Managing surface water before it pools is essential. We install high-capacity catch basin systems that collect heavy surface runoff, filter out leaves and debris, and channel the water into dedicated underground drainage pipes.
For hardscapes, our channel drain installations are the perfect defense. We strategically place these linear drains across driveway entrances, along patios and walkways, and in front of garage doors to prevent pooling water from breaching your home.

Downspout Drainage & Dry Wells
A single storm can dump thousands of gallons of water on your roof. If your downspouts discharge right next to your foundation, you’re risking a flooded basement. Our downspout drainage systems utilize heavy-duty underground pipes to extend your downspouts and route roof runoff safely away from your home.
For properties lacking an ideal discharge location, we offer dry well installation. These underground stormwater absorption systems act as a holding tank, allowing water to slowly and safely percolate back into the surrounding soil. This eco-friendly water dispersal method aligns perfectly with the EPA’s guidelines on green stormwater infrastructure.
Yard Grading and Landscape Drainage
Sometimes, the best defense against water is gravity. Proper yard grading is the foundation of any dry property.
Regrading for Proper Water Flow
If your yard slopes toward your home rather than away from it, water will inevitably pool against your foundation. Basement Expert provides precision regrading services to re-establish a positive slope, ensuring gravity works for you, not against you.
Drainage Swales for Water Diversion
For properties with significant terrain challenges, we sculpt subtle, highly effective drainage swales. These shallow, vegetated channels act as natural pathways, gently diverting massive amounts of water around your home and landscape without the need for extensive piping.
Why Proper Yard Drainage Is Essential in the Pacific Northwest
Heavy Rainfall Challenges in Seattle and Everett
Living in the Pacific Northwest means dealing with relentless rain. The heavy rainfall in the Seattle and Everett areas rapidly saturates the soil, leaving excess water nowhere to go but up into your lawn or down into your basement. Managing this unique regional climate requires robust, high-capacity drainage solutions designed specifically for PNW weather patterns. For more on how local runoff impacts our environment, you can read insights from the Washington State Department of Ecology.
Preventing Foundation Damage and Basement Flooding
Ignoring yard drainage doesn’t just ruin your grass; it jeopardizes your home’s structural integrity. Saturated soil expands, putting immense pressure on your foundation walls—eventually causing cracks, bowing, and flooding. Proactive water management is the most cost-effective way to avoid catastrophic foundation repairs and aligns with FEMA’s recommendations for mitigating residential flood risks.

Yard Drainage Common Questions from Everett Homeowners:
Look for warning signs such as standing water that lasts more than 24 hours after a rainstorm, patches of dead or continually muddy grass, water pooling near your foundation, or unexpected moisture in your basement or crawlspace.
There is no one-size-fits-all answer. If you have surface water pooling on a driveway, a channel drain is best. If you have subsurface groundwater making your lawn soggy, a French drain is ideal. Basement Expert will assess your property’s specific topography and soil type to design the exact system you need.
Most residential drainage projects are completed within 1 to 3 days, depending on the length of the system, soil conditions, and the complexity of the installation. We prioritize efficient work while minimizing disruption to your existing landscape.
