Chimney leaks in Kent have a particular shape because of the split-level. On East Hill and West Hill, the 1960s-80s brick chimney often runs up an outside wall for two full stories, so there is more flashing where it meets the roof, more mortar joints facing the rain, and a crown way up at the top. Leaks show as a stain on the upstairs ceiling near the chimney, damp drywall on the chimney wall in the family room below, or efflorescence on the outside brick. On the 1990s-and-later homes toward Lake Meridian and Covington, and in valley apartments, the chimney is a sided chase with a metal cover, and the leak is almost always a rusted or pooling cover or an unsealed flue collar.
We do not caulk everything and hope. The free quote includes finding the actual entry point, water-testing if needed, and pricing the specific fix: crown rebuilds start at $299, chase covers at $299, flashing and repointing quoted on site. Kent is about 15 minutes down SR 167 from our Renton office, so during the wet season we can often get there the same day before the next storm adds to the damage. Bring any other bid and we price match plus 10-25% off. If the stain comes back, we are not done.
Symptoms
Signs Kent 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
Kent Conditions
Why this happens in Kent
Kent sits under the same rain as Sea-Tac, a few miles to the northwest: 40.34 inches a year by the 1991-2020 normal, about 73% of it between October and March. November is the wettest month at 6.31 inches, with December at 5.72 and January at 5.78, and that three-month stretch is when most Kent leak calls come in. A small opening is enough; a hairline crown crack or a pinhole in a chase cover sees rain on most of the roughly 150-156 wet days a year.
The freeze-thaw pattern is what makes a small leak grow. Winter lows average 37-38F, so water sitting in a crack freezes overnight and thaws by afternoon many times a season, and the Brick Industry Association notes that saturated masonry under repeated freeze-thaw cracks, spalls and disintegrates. On a tall exterior East Hill chimney, that works on the flashing line and the lower joints as much as the crown. Moss, which spreads fastest October through April on shaded surfaces, holds water in the north-facing joints between storms.
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 Kent — FAQ
The upstairs ceiling next to my Kent split-level chimney is wet. Chimney or roof?
On an exterior split-level chimney it is usually the crown, the step flashing where the chimney meets the roof, or open joints on the weather face. We check all three and the cap, tell you which it is, and if it turns out to be the roof or a gutter we will say so rather than sell chimney work. The quote is free.
Can you stop a Kent chimney leak temporarily until it dries out enough to repair?
Yes. If we find the entry point during a storm, we can cover the top or the bad section the same visit so the water stops, then come back for the permanent crown, flashing or chase cover work on the next dry day. Kent is close enough to Renton that the return trip is usually within a few days.
How soon can you do chimney leak repair in Kent?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Kent and the rest of King County.
