A Lake Forest Park chimney leak usually shows up as a brown ring on the ceiling next to the fireplace in late November, a damp smell in the family room, or paint lifting on the wall above the mantel. The mid-century brick chimneys typical of the neighborhoods between Bothell Way NE and the ridge have three common entry points: a cracked crown that lets water down the outside of the flue tile, step flashing that has pulled away from brick on the uphill side of the roof, and mortar joints that have gone porous in the permanent shade of the trees. Near Sheridan Beach, wind-driven rain off the lake adds a fourth.
We start with a water test and a look from the roof and the attic, so we fix the actual source rather than the most visible one. Repairs range from resealing and re-stepping flashing, to tuckpointing the exposed face, to a crown rebuild starting at $299 when the top has failed. The quote is free, we price match and take 10-25% off a written bid, and Lake Forest Park is about 35 minutes from Renton, so we can often get a tarp or a temporary seal on the same day. If you are not happy, we are not done.

Lake Forest Park Conditions
Why this happens in Lake Forest Park
The local climate explains why leaks here show up inside so slowly. By the Sea-Tac 1991-2020 normals, November is the wettest month at 6.31 inches, with December at 5.72 and January at 5.78. The water does not arrive as one downpour; it soaks the masonry over roughly 150-156 rainy days a year, and a Lake Forest Park chimney under tree cover on a ravine lot off NE 178th Street or Brookside Boulevard may not dry out between them. The Brick Industry Association notes that poorly filled mortar joints are a main cause of leaky masonry walls, and that applies to chimney stacks.
Moss makes the flashing problem worse. Regional roofing guidance holds that Western Washington moss spreads fastest October through April on shaded, slow-drying surfaces, and a moss mat along the uphill side of a chimney dams water against the flashing exactly where it meets the brick. Clearing that line and resealing the joint is often the whole fix for a Lake Forest Park leak.
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 Lake Forest Park — FAQ
How do you tell whether my Lake Forest Park leak is the chimney or the roof?
We water test. Starting low and working up, we wet the flashing, the brick face and the crown separately while someone watches inside, so we can see which section produces the drip. On the shaded, moss-prone roofs here, the flashing and the crown are the usual answers, but we confirm before quoting so you are not paying for the wrong repair.
Can you stop the leak before the next storm?
Often yes. Lake Forest Park is about 35 minutes from our Renton office, and if the entry point is flashing or a crown crack, we can usually apply a temporary seal the same day and return for the permanent repair during a dry window. The quote is free and we show you the photos from the roof before any work.
How soon can you do chimney leak repair in Lake Forest Park?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Lake Forest Park and the rest of King County.
