Basement waterproofing in Sumner: what to know

Our first visit checks the grade on each side of the house, the gutters and downspouts, and any drain line already in place. Where a sump or interior drain is the right answer, the pit and the discharge get the same attention. We confirm the outlet for any sump discharge with the city before the pump is set.

Any dig for an exterior drain, a footing, or a wall repair is checked two ways. First, the work stays on your lot unless it reaches the right-of-way, and grading there needs the Sumner permit center’s written permit. Second, any connection to a sewer or storm line is settled with the city before we open the ground. The city pages we reviewed give no excavation depth or volume for a basement dig, so we confirm that point for each address before anything is excavated.

Permits and rules in Sumner

A basement job can raise three city questions: whether the dig needs a building permit, whether any work reaches the right-of-way, and whether a sewer or storm connection is involved. Sumner Municipal Code Chapter 12.28 covers the right-of-way question, and it requires a written permit for grading there. We confirm the other two for your address before the price is set, and our quote lists which answers are settled and which are still open.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

Questions from Sumner homeowners

Does a basement dig in Sumner need a building permit?

Whether it does depends on the dig itself, so we confirm the permit question with the city for your address before the ground is opened. Work that reaches the right-of-way also needs the Sumner permit center’s written permit for grading.

Where does a sump pump discharge in Sumner?

The outlet is one of the points we settle before the pump is set. We do not run a discharge onto a neighbor’s lot, and we do not tie one into a sewer or storm line until that connection is confirmed.

Can a basement drain connect to a city storm line?

Only after the connection is confirmed. Sewer and storm connections are part of what we check for each address, so the answer comes first and the line is planned after it.
