Crown repair that starts with an assessment
Choosing the sealant for the flue joint
Not every tube of caulk belongs on a chimney top. Brick industry guidance recommends a good grade of polysulfide, butyl or silicone rubber sealant at this joint and warns against oil-based sealants. Proper priming and a backing rope are part of the detail.
We tell you which sealant family we plan to use and why. The joint is cleaned and prepared before the new bead goes in. If an earlier repair used a product that has cracked or hardened, we remove it rather than run a new bead over the top.
Crown cracks that start at a flue tile
A pattern of cracks spreading out from one flue tile is a useful clue. The crown may have been cast tight against the liner, with repeated heating pushing it apart. Water then follows the same lines into the chimney.
Filling those cracks without freeing the liner joint may not stop them returning. We check whether the crown can be cut back and resealed at the liner or whether it has broken up too far. Either way, you see the cause explained, not just the crack.
Comparing chimney crown estimates fairly
Crown estimates can describe very different jobs under the same name. One may mean a coating, another a patch and another a new crown. Comparing prices only makes sense when the scopes match.
Ask each contractor how they handle slope, overhang, drip edge and the bond break at the flue. Ask what happens to loose concrete and what product is used. Our estimate answers those questions in writing, so you can compare it line by line with any other proposal.
Mortar joints just below the crown
The mortar joints in the top courses of brick can wear before those lower down. They sit right under the crown and take water whenever the crown fails. Open joints there let water into the wall even after the crown is repaired.
We check those joints as part of the crown inspection. If they need repointing, that is joint work with its own line on the estimate. Doing it at the same visit can make sense because access is already in place, but you decide whether to include it.
What the free crown inspection covers
- Slope and drainage off the top
- Bond break at each flue liner
- Removal of loose or hollow sections
- Cap removal and reinstallation
Questions to ask before crown repair
Why does a new crown need to overhang the brick?
An overhang with a drip edge throws water clear of the brick face instead of letting it run down the chimney. The code also calls for a drip edge on the top of a masonry chimney. Without one, water can keep soaking the top courses.
What does the free inspection include for a chimney crown?
We look at the crown surface, edges, slope, overhang and the seal at every flue, plus the cap fixings and the brick just below. You hear the findings on site and receive a free written estimate that keeps each item separate.
Will crown work damage my roof covering?
The roof is protected where we stand, stage material and apply products. Spills are cleaned as the work proceeds. Tell us about fragile roofing before the visit so the access plan accounts for it.
