A chimney leak in Kenmore usually shows itself after one of the big storms that run up Lake Washington from the south. On the 1950s-70s ramblers in Uplake and Arrowhead the water comes through a cracked crown, a missing cap, or step flashing that has let go of old brick on the lake-facing side, and it shows as a stain on the ceiling by the fireplace wall or as a damp smell in the firebox. On the newer homes up in Inglewood, Moorlands and along SR 522 it is more often a rusted chase cover or a storm collar that slid down the pipe, and the stain shows on the chase wall upstairs.
We find the actual entry point as part of a free quote, because a chimney leak gets blamed on the roof often enough that people pay twice. Then we do the fix that matches: crown rebuild starting at $299, chase cover replacement starting at $299, reflashing, a new cap, or a masonry water repellent. If you already have a bid, ours is a free second opinion and we price match and take 10 to 25 percent off. Kenmore is about 35 minutes from our North Renton office, so same-day service is often available. If you are not happy, we are not done.
Symptoms
Signs Kenmore 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
Kenmore Conditions
Why this happens in Kenmore
Kenmore chimneys take their rain sideways. A south wind pushes storms the full length of Lake Washington and lands them on the Kenmore shore, so a chimney on an Uplake or Arrowhead home gets rain driven into the joint between brick and flashing rather than just onto the crown. November averages 6.31 inches here, the wettest month, and the October-to-March season carries about 29.65 of the year's 40.34 inches, so a chimney that only drips in November is soaking its framing for months.
Freeze-thaw then opens every gap. With about 60 days a year touching 32F and winter lows averaging 37-38F, water sitting in a crown crack or under a lifted flashing edge freezes overnight and thaws by noon, prying the gap wider each cycle. Up in the wooded lots near Saint Edward State Park, moss on the shaded side adds a sponge that keeps the masonry wet. The earlier we see the stain, the smaller the fix.
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 Kenmore — FAQ
My Kenmore roof was replaced recently and the chimney still leaks. Why?
Roofers often reuse the old chimney flashing or counterflashing, and on an older brick chimney the mortar joint the counterflashing sits in has usually opened. Or the leak was never the flashing, it was the crown or a missing cap. We run a hose test to find the real entry point as part of the free quote.
Can you stop a Kenmore chimney leak in the middle of winter?
Yes. Caps, chase covers and flashing repairs go on in any weather, and we can seal a cracked crown to get you through the wet season and pour the new crown, starting at $299, in a dry stretch. The point is to stop the water first, then do the permanent repair on a day it will cure.
How soon can you do chimney leak repair in Kenmore?
