Maple Valley chimney leaks tend to show up in November and get blamed on the roof. In the subdivisions around Four Corners, Wilderness Village, the Summit and the plats off SE 240th, the chimney is a siding-wrapped chase with a metal cover on top, and when the cover rusts through or the storm collar slips, water runs down the pipe and stains the ceiling beside the fireplace. On the older brick chimneys of the lakefront homes around Lake Wilderness and Pipe Lake and the acreage along the Cedar River, water gets in through a cracked crown, an open mortar joint on the weather side, a missing cap, or step flashing that has pulled away from the brick.
We find the entry point first, from the roof and with a camera in the flue, and then repair that point: a stainless chase cover starting at $299, a sealed storm collar, reset flashing, a crown repair starting at $299, or tuckpointing. You get a free quote first, a free second opinion on any bid, and a price match with 10-25% off. Maple Valley is about 25 minutes from our Renton office up SR 169, and we can often come the same day while the leak is active and easy to trace. If you are not happy, we are not done.

- White crusty efflorescence on the brick inside or outside

- 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
Maple Valley Conditions
Why this happens in Maple Valley
Maple Valley leak calls follow the rain. Sea-Tac's normals show November as the wettest month at 6.31 inches, and November through January together average about 17.8 inches, roughly 44% of the 40.34-inch annual total. A crown crack that stayed quiet through a 0.60-inch July drips in the first November storm. Under the fir and cedar canopy around Lake Wilderness and along the Cedar River, the top of the chimney never dries between storms, and Western Washington moss, which spreads fastest October through April on shaded surfaces, grows in the crack and keeps feeding it water.
Freezing widens the path. December, January and February lows average 37-38F and about 60 days a year dip to 32F, so water sitting in a crown crack, a mortar joint or a rust pocket freezes overnight, expands and opens the gap a little further, then lets in more water the next day. A leak caught in its first winter is a cover, a collar or a crown seal; after a few winters it can be rotted framing or loose brick.
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 Maple Valley — FAQ
The roofer says my Maple Valley roof is fine but the ceiling by the fireplace keeps getting wet. What is next?
That pattern usually means the chimney. On a sided chase it is typically the cover or the storm collar; on a lakefront brick chimney it is the crown, joints or flashing. We inspect from the roof and camera the flue to confirm the entry point, then give a free quote, a free second opinion on any bid you already have, and match and discount the price.
Will you come out to Maple Valley to fix a chimney leak while it is still raining?
Yes. An active leak is easier to trace, and covers, collars, caps and flashing can be repaired in wet weather. Crown and mortar work on the Lake Wilderness and Cedar River brick chimneys needs a dry window, and since we are 25 minutes away in Renton we can return the first dry morning to finish.
How soon can you do chimney leak repair in Maple Valley?
