Chimney crown repair deals with the concrete slab that caps the top of a masonry chimney. The crown should slope away from the flue on every side, overhang the brick by about two inches, and have a drip edge cut underneath so water falls clear of the chimney face.

Most crowns we see were never built that way. A lot of them are a thin layer of mortar troweled flat over the top course of brick. Mortar is not concrete. It shrinks, cracks, and lets water straight down into the chimney, where freeze-thaw cycles push the brick apart from the inside. That is often the source of a leak that homeowners blame on the flashing.

For hairline cracks we clean the crown and apply a flexible crown sealant made for masonry. For a crown that is broken, flat, or pulling away from the flue tile, our crew tears it off and forms a new one with a bagged crown mix, a proper slope and a bond break around the flue so the tile can expand without cracking the new slab.

A crown repair is a good time to add chimney cap installation and to look at the mortar below with chimney tuckpointing. Call (833) 583-1301 to book chimney leak repair from the top down.

Chimney Flashing Repair FAQs

Questions about chimney flashing repair

Questions we hear about Chimney Crown Repair in Capitol, MT.

Call (833) 583-1301
Can you just seal my chimney flashing with caulk?
Caulk is a temporary patch, not a repair. Sealant bonds poorly to dusty brick and breaks down in the sun, so a caulked joint usually fails within a couple of years. A lasting fix is step flashing under each shingle course with counter flashing set into a ground mortar joint above it.
What is the difference between step flashing and counter flashing?
Step flashing is the set of small L-shaped pieces tucked under each shingle course along the side of the chimney. Counter flashing is the metal set into the brick that laps down over the step flashing. The two work as a pair. One without the other leaks.
Can a chimney leak be fixed in winter?
Flashing and caps can be installed in cold weather if the roof is dry and free of ice. Mortar work and crown repairs need temperatures above about 40 degrees for the mix to cure, so in cold months we may tarp and flash first, then finish the masonry in spring.
Why does my chimney leak only in heavy storms?
Light rain runs off. Heavy, wind-driven rain gets pushed sideways into loose counter flashing, through open mortar joints and into an uncapped flue. If your leak only shows up in big storms, the flashing and the brick face are the first things we check.
How do I get a quote for chimney flashing repair?
Call (833) 583-1301. We will ask a few questions about where the water shows up and what the roof looks like, then set a time for our crew to look at it in person.
