A chimney leak in Des Moines almost always shows up after a southwest storm. Stains beside the chimney or drips on the hearth of a Marine View Drive rambler usually trace to the side facing the Sound. On the bluff homes above the Des Moines Marina and down through Redondo and Woodmont, the brick chimney is typically on the outside wall with the most weather exposure, and wind pushes rain through openings an inland rain would miss: a hairline crack in the crown, a mortar joint that has opened, a missing cap, or step flashing that has pulled away from the brick. On the factory-built chimneys east of Pacific Highway S, it is usually a rusted chase cover or slipped storm collar.
We find the actual entry point before fixing anything, using a roof inspection and a flue camera, and then we repair that point: crown repair, cap, flashing reset, tuckpointing, or a new chase cover. A free quote comes first, and a free second-opinion quote if a roofer has already blamed the chimney. We match any written price and take 10-25% off. Des Moines is 20 minutes from our Renton office, so same-day service is often available while the leak is still active and easy to trace. If you are not happy, we are not done.
Symptoms
Signs Des Moines 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
Des Moines Conditions
Why this happens in Des Moines
Des Moines chimneys leak because of how much rain arrives and the direction it comes from. Sea-Tac records a 40.34-inch annual normal with November the wettest month at 6.31 inches, and November through January together average about 17.8 inches, roughly 44% of the year's total. That is the stretch when we get the most leak calls from the bluff. Rain that falls sideways off the Sound reaches the underside of caps and the vertical face of flashing that a straight-down rain never touches, so a chimney that was dry for years on Saltwater State Park's shaded hillside can start leaking after one hard blow.
The cold makes small openings bigger. Winter lows average 37-38F and about 60 days a year touch freezing, so water that has soaked into a Redondo chimney's crown or joints expands overnight and widens the crack, then more water gets in the next storm. Catching a leak in its first winter is much cheaper than after two or three of those cycles.
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 Des Moines — FAQ
The ceiling next to my Des Moines chimney only gets wet during windstorms. Is that the roof or the chimney?
On the bluff that pattern usually points to the chimney. Wind-driven rain off the Sound reaches the crown, the underside of the cap and the exposed face of the flashing. We inspect the roof and run a camera up the flue to find the actual entry point before we quote, and the quote is free, so you are not paying to guess.
Can you repair a chimney leak in Des Moines during the rainy season?
Yes, and an active leak is easier to trace. Caps, chase covers, storm collars and flashing can be repaired in wet weather. Crown coatings and mortar work need a dry window, which we watch for; Des Moines is 20 minutes from Renton, so we can come back the first dry morning to finish.
How soon can you do chimney leak repair in Des Moines?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Des Moines and the rest of King County.
