Chimney leaks in Sumner tend to follow the age of the house. In the historic downtown around Main Street, the tall brick chimneys typically leak from the top: a mortar-wash crown that has cracked through, open joints in the upper courses that drink rain, or a cap that was never installed, so water runs straight down the unlined flue and shows up as a damp smell and dark streaks in the firebox. In the newer plats east of SR 410 and toward Lake Tapps, leaks are typically at the chase cover or the storm collar on a factory-built chimney, and the first sign is a ceiling stain beside the fireplace or rust streaks on the siding.
We trace the water to its source before repairing anything. That might mean a crown rebuild starting at $299, repointing the upper courses, a new cap, a chase cover starting at $299, or new flashing where the chimney meets one of downtown Sumner's steep roofs. Sumner is about 35 minutes from our Renton office via SR 167 and SR 410, so an active leak can usually be looked at the same day.

Symptoms
Signs Sumner homeowners notice
- Water pooling in the firebox or dripping from the damper after rain
- Brown stain on the ceiling or wall beside the chimney that grows during the wet season
- White crusty efflorescence on the brick inside or outside
- Rust streaks down the siding of a framed chimney or down the face of the brick
- Spalling brick faces or crumbling mortar near the top of the chimney
- Damp firebox walls even when it has not rained for a day or two
Sumner Conditions
Why this happens in Sumner
Sumner's valley-floor setting between the White and Puyallup rivers keeps the wet season wet. The region takes 40.34 inches of rain a year by the Sea-Tac 1991-2020 normals, and November through January alone carry roughly 44 percent of it. A tall downtown chimney with open top joints absorbs water through that whole stretch and never dries out, which is why leaks here often appear as damp brick inside the house rather than a single drip.
Once the brick is saturated, the region's winter lows of 37 to 38F mean it freezes and thaws repeatedly. The Brick Industry Association documents that freezing water in saturated masonry expands and causes cracking and spalling, each cycle opening the path a little wider. Fixing a Sumner leak in early fall, before the November rains, stops that cycle before it turns a repointing job into a top-of-chimney rebuild.
How It Works
Our chimney leak repair process
Map the symptom
We ask where the water shows up, when, and how long after rain, because each entry point leaves a different signature.
Check the top
Crown, cap and chase cover are inspected first, since they are the most common leak sources and the fastest to rule in or out.
Check the roofline and masonry
Flashing, mortar joints, spalled brick and the flue itself are checked, including for condensation that mimics a leak.
Fix in the right order
We repair the entry points that are actually leaking, from the top down, and leave the sound ones alone.
Water-test and follow up
Where possible we run water on the repair to confirm it is dry, and if the next storm proves us wrong, we come back at no charge.

Chimney Leak Repair in Sumner — FAQ
The brick around my Sumner fireplace feels damp but there is no drip. Is that a leak?
Yes, and it is the most common kind on old downtown Sumner chimneys. Water entering through a cracked crown or open top joints soaks down through the brick and shows up inside as dampness, efflorescence or a musty smell rather than a drip. We find the entry point from the roof and give you a free quote to seal it.
My Sumner home is newer. Why would the chimney already be leaking?
Builder-grade galvanized chase covers on 1990s-and-later prefab chimneys east of SR 410 rust through faster than most people expect in this climate, and storm collar sealant dries out. Both let water into the framed chase. A stainless chase cover starting at $299 usually solves it, and we check the collar and flashing at the same visit.
