Where an Auburn chimney leaks depends a lot on which part of Auburn the house is in. In Lakeland Hills and Lea Hill, the 1990s-2010s homes mostly have prefab fireplaces inside framed, siding-clad chases, and the usual leak source is the sheet-metal chase cover on top: rusted through at a seam, pooling in the middle, or not sealed at the pipe collar. In the older valley and downtown homes with brick masonry chimneys, water usually gets in through a cracked crown, washed-out mortar joints, porous brick or failed step flashing where the chimney meets the roof. Both kinds of leak tend to show up as a ceiling stain next to the fireplace or moisture in the firebox after a storm.
We trace the water to its source before recommending anything, because sealing the wrong place only delays the next stain. Fixes range from a new chase cover starting at $299 to a crown rebuild starting at $299, new flashing, tuckpointing, or a breathable water repellent on brick. You get a free quote, a free second-opinion quote if someone else has already diagnosed it, and we price match plus 10-25% off. If the leak returns, we return at no charge.
Symptoms
Signs Auburn 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
Auburn Conditions
Why this happens in Auburn
Auburn gets about 40 inches of rain a year, and the pattern is what makes chimney leaks here so persistent: roughly 73% of it falls between October and March, with November the wettest month at over six inches. A chase cover or crown with a small defect might shed ordinary summer rain fine and then fail every week through the wet season. On the hills, the galvanized chase covers installed when Lakeland Hills and Lea Hill were built out are typically at the age where rust has opened seams, and the pipe collar sealant has dried out.
On the valley brick, the leak path is usually freeze-thaw damage. The area sees about 60 days a year that touch freezing while winter lows average just above 32F, so water in a crown crack or an open mortar joint freezes overnight and thaws by afternoon, repeatedly, widening the opening each winter until it becomes a leak into the house.
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 Auburn — FAQ
The siding on my Lakeland Hills chimney chase has rust streaks. Is that a leak?
It is the usual early warning. Rust streaks on a chase mean the metal chase cover on top is corroding, and a corroded cover typically has or soon will have a hole letting water into the framing. We inspect the cover and pipe collar during the free quote and replace the cover starting at $299 if needed.
Can you tell if my Auburn leak is the chimney or the roof?
Yes, that is the first thing we determine. We check the crown or chase cover, the flashing and the masonry or chase itself, and trace the water path to the stain. If the source is in the roof field rather than the chimney, we tell you plainly so you can get the right trade. The diagnosis and quote are free.
