A chimney leak in Monroe usually shows up as a brown ring on the ceiling beside the chimney, a damp smell from the firebox after a storm. Where it comes from depends on the house. The older brick chimneys downtown and on the farm properties along the Skykomish typically leak at the flashing, where a steep old roof meets a wide stack with no cricket behind it, or through a cracked crown that lets water run down inside the brick. In Fryelands, North Hill and the plats off Chain Lake Road the usual culprit is a rusted galvanized chase cover or a storm collar that has pulled away from the pipe.
We do not guess. We inspect the crown, flashing, cover and brick, water-test if the source is not obvious, and show you photos of where the water gets in. Then we fix that spot: reflash, rebuild the crown starting at $299, replace the chase cover starting at $299, or repoint and seal the brick. The quote is free, and another company's leak estimate gets a free second opinion and a price match plus 10-25% off. Monroe is about 55 minutes from Renton, and we can often get a temporary cover on the same day to stop the water while the permanent fix is scheduled.

Monroe Conditions
Why this happens in Monroe
Monroe leaks show up in November for a reason. It is the wettest month on the Sea-Tac 1991-2020 normals at 6.31 inches, and November through January together carry about 17.8 inches, roughly 44 percent of the year's 40.34. That is when a hairline crown crack or a lifted flashing corner that did nothing all summer finally lets enough water through to stain drywall. With measurable rain on roughly 150-156 days a year, a Monroe chimney also rarely dries out between storms, so brick that has lost its mortar stays saturated and wicks water down into the house.
The valley's tree cover adds moss. Chimneys on the shaded side of a roof near Lake Tye or along Woods Creek typically grow moss on the crown and in the flashing seams, and regional roofing guidance notes it spreads fastest October through April on surfaces that dry slowly. Moss holds water against the masonry, and with around 60 freezing days a year the trapped water freezes, widens the crack and makes next winter's leak bigger.
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 Monroe — FAQ
The ceiling next to my Monroe chimney only stains in November. Why?
Because November is the wettest month in the region, 6.31 inches on the Sea-Tac normals, and it follows a dry summer in which the crack or flashing gap was too small to matter. Once the chimney is saturated, water finds the same path every storm. We trace it, fix the entry point, and the stain stops returning. The quote is free.
Can you repair a chimney leak in Monroe during the rainy season?
Yes. Flashing and chase cover work can be done in almost any weather, and we watch for a dry window for crown and mortar work so it cures properly. When rain will not quit, we install a temporary cover the same day to stop the water, then come back for the permanent repair. Monroe is about 55 minutes from our Renton office.
How soon can you do chimney leak repair in Monroe?
