French Drain Installation

French Drain Installation in Snohomish & King County

The Pacific Northwest gets serious rainfall — and in the North Sound, clay-heavy soil means that water doesn't go anywhere fast. Wet basements, saturated crawlspaces, pooling water against foundations, and soggy yards are all drainage problems that a properly installed French drain solves permanently.

Danika Plumbing designs and installs French drain systems for residential properties across Snohomish and King County. We assess the grade, soil conditions, and water source before we dig — because a French drain installed in the wrong location or without proper outlet planning just moves the problem somewhere else.

Our french drain installation services include:

  • Perimeter French drain installation
  • Interior basement drainage systems
  • Crawlspace drainage and vapor barrier
  • Yard and landscape drainage correction
  • Downspout extension and dry well integration
  • Storm drain connection where permitted

Our French Drain Process

How We Install French Drains That Actually Work

French drains fail when they're installed without proper grading or outlet planning. Here's how we do it right.

1
Site Assessment and Water Source IdentificationWe walk your property after rain if possible. Where is the water coming from? Roof runoff, groundwater, uphill surface flow, or foundation seepage? The source determines the solution.
2
Grade and Outlet SurveyA French drain needs somewhere to drain to. We confirm that the outlet point — daylight, dry well, storm drain — is achievable and legal before we design the system.
3
Design the SystemPipe sizing, gravel type, filter fabric, depth, and slope are all engineered for your specific site. A residential French drain isn't just a ditch with a perforated pipe.
4
Excavate and InstallWe excavate the trench, install the filter fabric, set the perforated pipe at the correct slope, fill with clean drain rock, and wrap the fabric over the top.
5
Connect the OutletThe outlet is just as important as the collection trench. We install a proper discharge point that keeps water away from the foundation and neighboring properties.
6
Backfill and RestoreWe backfill with appropriate material, restore the surface, and verify the system drains correctly under a hose test before leaving the site.
