Chimney Leak Repair in Kansas City
$69 inspection — credited back in full when you book the repair
Chimney leak repair means locating the real water entry point — flashing, crown, cap, or porous masonry — and fixing that, rather than sealing the ceiling stain and hoping.
When you need this
- A brown ring on the ceiling or wall beside the chimney breast
- Damp or musty smell from the firebox after rain
- White chalky deposits on interior brick
- Peeling paint or crumbling drywall next to the chimney chase
- Water audibly dripping onto the damper
- Rust on the damper or firebox floor
What the visit includes
- Systematic water testing from the bottom up to isolate the actual entry point
- Flashing repair or full replacement with proper step and counter flashing let into a cut reglet — not surface caulk
- Crown rebuild or repair where the crown is the source
- Cap or chase cover installation where the flue is open to the sky
- Vapour-permeable masonry waterproofing after the repair, never instead of it

What drives the price
We publish what moves the number rather than a single figure, because a quote that turns out to be low helps nobody.
- How many entry points there are — chimney leaks very often have two
- Flashing type: a proper counter-flashing reglet cut into the mortar joint costs more than caulk and is the only version that lasts
- Whether interior damage (firebox, smoke chamber, drywall) also needs addressing
- Roof material — tearing back and reinstalling architectural shingles versus a standing-seam metal roof are different jobs
- Whether the masonry itself is saturated and needs to dry before sealing
Typical Kansas City range
$200 – $1,200
Kansas City range for chimney leak repair. Simple flashing work at the low end; crown rebuild plus flashing plus cap at the high end.
Why it matters
A chimney leak does not stay a chimney problem. Water tracking down the outside of the flue reaches the framing, the ceiling and eventually the sill plate, and by the time it shows on the drywall it has usually been running for a season.
Questions we get asked
Why not just caulk it?
Caulk on flashing is a one-to-two-year fix that hides the problem while the framing behind it stays wet. Proper counter flashing is cut into the mortar joint and mechanically held; it outlives the roof.
Should I waterproof the brick?
Yes, but only after the joints are sound and only with a vapour-permeable siloxane product. A film-forming sealer traps moisture inside the brick and accelerates spalling through our freeze-thaw winters.
It only leaks in heavy rain. Is that still a problem?
It is a normal pattern and it still needs fixing. Wind-driven rain finds entry points that vertical rain does not — the leak is there year round, it just needs the right storm to show itself.
Related services
Repair
Chimney repair covers the masonry itself — repointing failed mortar joints, replacing spalled brick, rebuilding a cracked crown, and in the worst cases taking the stack down to a sound course and rebuilding it.
Cap Installation
A chimney cap is a stainless or copper cover with a spark screen that sits over the flue opening, keeping rain, animals and debris out of the chimney while still letting exhaust and draft through.
Inspection
A chimney inspection is a documented condition assessment of the flue, liner, firebox, crown, cap and flashing, delivered as a written report with photographs rather than a verbal opinion.
