Washington Drain Cleaning serves Longview homes and businesses from its Seattle location at 3958 NW Leary Wy. Crews reach the city via I-5 to clear slow drains and backups in neighborhoods such as Downtown Longview, West Longview, Highlands and Mint Valley.
Longview's planned layout and paper-industry past mean many properties have older sewer lines that collect grease and debris. Mild, rainy winters near the Columbia River add extra water volume that pushes tree roots and sediment into pipes more often than in drier parts of the state.
Customers along WA-4, WA-432 and near the Cowlitz River commonly request same-day visits for kitchen and laundry clogs. The team works Monday through Friday 8am to 6pm and Saturday 9am to 2pm to match local schedules.

Drain Cleaning in Longview — Local Notes
- •Older planned-city homes often have clay or cast-iron lines that crack and collect roots after decades of Columbia River moisture.
- •Heavy winter rain funnels extra runoff into storm drains that share lines with older residential sewers in West Longview and Highlands.
- •Access to Mint Valley and areas near Lake Sacajawea requires navigating narrow streets and park-adjacent lots that limit large equipment.
- •Cowlitz County permits are required for any excavation near the river corridor, so crews schedule inspections in advance for those jobs.
