Seattle gets plenty of rain, and all that water has to go somewhere. Storm water management covers the drains, grading, catch basins, and pipes that move runoff away from your home or property instead of letting it pool against a foundation or flood a basement. This page lists local providers who handle that work across Seattle and the wider Washington area, so you can compare your options in one place rather than starting from a blank search.
Look for a company that inspects the site before quoting, explains what is actually causing the water problem, and puts the plan in writing. Ask whether they handle both the diagnosis and the repair, and whether they carry the licensing your project needs. Reviews on Google Maps can help you gauge how a provider treats customers, but a walkthrough of your property is what tells you whether they understand your specific drainage issue. Browse the providers below, check what each one focuses on, and reach out to a couple for quotes before you decide.

Frequently asked questions
How much does storm water management cost in Seattle?
Pricing depends on what is causing the problem and how much work it takes to fix. Clearing a blocked drain is very different from regrading a yard or installing a new catch basin system. Most Seattle providers assess your property first, then quote based on the scope. Ask for the estimate in writing, and check whether it covers both the diagnosis and the actual repair.
How do I choose a storm water management provider?
Start with a provider who inspects before quoting rather than pricing the job over the phone. Ask how they plan to move water away from your foundation, whether they hold the licensing your project requires, and what happens if the fix does not hold. Google Maps reviews give a sense of reliability, but a site visit is what tells you whether they understand your drainage setup.
When is a drainage problem urgent?
Water pooling against your foundation, a basement that floods in heavy rain, or runoff eroding your yard are worth acting on quickly, since standing water can damage a structure over time. Slow drainage or a soggy lawn is less pressing but still worth a professional look. If you are unsure how serious it is, most providers will inspect and tell you what needs attention now versus later.
What does storm water management actually involve?
It covers the systems that collect and redirect rainwater, including surface grading, French drains, catch basins, downspout lines, and the pipes that carry runoff to a safe outlet. The goal is to keep water from collecting where it can damage a building or landscape. A provider figures out where water is going wrong on your property and designs a way to send it somewhere better.
Can I handle drainage problems myself?
Small tasks like clearing a downspout or a surface drain are often DIY-friendly. Once the work involves digging, regrading, or tying into underground pipes, a professional is usually the safer call, because a poorly placed drain can send water toward your foundation instead of away from it. Some projects may also need permits, which a local provider can help you sort out.
