Getting a stone chimney repair right in Hibiscus
How the masons who repoint stone in Hibiscus explain the work to neighbors.
Full mortar coverage behind each stone
The same instructions require a setting bed with complete coverage of the back of each unit and full contact between mortar, stone and backing. Stones are back-buttered to fill their textured backs, then pressed into a half inch to three quarters of an inch of mortar until it squeezes out around the whole edge.
Stones set with a few dabs of mortar leave voids behind them. Those voids hold water and let stones pop off. When we reset veneer, every stone goes back with full coverage.
Keeping joints narrow and full
For manufactured stone, the maker's instructions say joints should be as narrow as possible, averaging no more than half an inch, and filled completely with a grout bag where more mortar is needed. The setting bed should cover the scratch coat fully so no pockets form behind the stones.
Repairs that leave wide or half-filled joints stand out and let water in. We fill joints completely, match their width to the wall around them and tool them to the same profile.
Mortar for manufactured stone repairs
Setting mortar has its own standards. The instructions we follow list mortars meeting ASTM C270 Type N or Type S, or ASTM C1714 Type N or Type S, for setting manufactured stone, with admixtures, bonding agents and pigments meeting their own ASTM standards.
We choose within those types to suit the job and follow the mortar maker's mixing and open-time directions, since over- or under-mixing can weaken the bond. The estimate names the mortar, so you know what goes on your chimney.
Roof flashing on a stone chimney
The line where a stone chimney meets the roof needs flashing built for it. The manufactured stone instructions we follow note that chimney or chase construction should incorporate proper flashing, and irregular natural stone makes the detail harder to get right.
Failed flashing can soak stones near the roof and the framing behind them. We check it from the roof, look for stains in the attic where it is accessible and list any flashing repair on its own line.
Veneer set on old brick or block
Stone veneer can be applied directly to clean, untreated, unpainted masonry or concrete. The maker's instructions we follow note that painted, sealed, dirty or smooth surfaces need extra preparation, and recommend a site evaluation for existing unit masonry and engineering review for existing stucco.
When veneer on a masonry chimney lets go, the surface behind it is often the reason. We look at it closely before resetting anything and explain the preparation it needs.

Asked in Hibiscus about stone chimney repair
What homeowners in Hibiscus ask while we are up on the roof, answered here.
Should my stone chimney be sealed?
Sometimes, but not by default. One manufactured stone maker says sealers are not necessary on its product and, if used, should be breathable silane or siloxane types, since a sealer can slow moisture leaving the stone. We explain whether a sealer suits your chimney.
How often should a stone chimney be inspected?
Under NFPA 211, a chimney, its fireplace and its vents are inspected every year at a minimum. For a stone chimney, that yearly visit is a good time to tap the stones, check the joints and look at the cap and flashing.
