Question 2

Question 3

Do I need a permit for drainage work in Washington?

Accepted Answer

Most residential drainage installations do not require a permit unless they connect to the public storm system or involve significant grading. Our team is familiar with local requirements across King, Snohomish, and Skagit counties and can advise you.

Question 4

What's the difference between a French drain and a catch basin?

Accepted Answer

A French drain is a gravel-filled trench with a perforated pipe that collects and redirects subsurface water. A catch basin is a surface-level inlet that collects standing water from the top of the ground. Many yards benefit from both working together.

Question 5

Will drainage work damage my landscaping?

Accepted Answer

There will be some excavation, but our crews are careful to minimize disruption. We restore disturbed areas after installation and most homeowners find their yard looks better than before once the drainage problem is solved.
