Repair Options

Veneer, joint and stone repairs for Markham chimneys

Where the chase cover meets the stone

Where a framed chimney is clad in stone, the metal chase cover should lap down over the top of the veneer. The industry detail shows at least 1 inch of overlap, so water running off the cover drips clear of the stone instead of into the top course. A short or rusted cover sends water straight behind the veneer.

If the cover needs work, a new chase cover is quoted as a separate item. Our family-owned team explains how the two fit together in Markham.

Mortar softer than the stone

Repointing mortar, in Park Service guidance, should be softer and more permeable than the stone it holds and no harder than the original mortar. When a chimney moves with heat and moisture, a soft joint takes the strain. A hard, cement-rich joint pushes that strain into the stone, which is how edges spall and faces crack.

We choose the mortar for your stone, not the strongest bag on the shelf. Our family-owned team explains the choice to homeowners in Markham.

Dry-stack style veneer

Some manufactured stone is laid tight with no visible grout joint, a look often called dry stack. Repairs on that style leave no grout lines, so the units have to be cut and fitted closely and set without mortar smeared across their faces. Mixing the two styles in one repair stands out from across the yard.

We match the style your chimney already has. Book a free stone chimney inspection in Markham and see how the repair will look.

The top of a stone chimney

Water entering at the top of a stone chimney runs down inside the stonework, softening joints and loosening stones well below. A cracked mortar top, a broken stone cap or a short chase cover can all let it in. We check the top whenever we repair the stone beneath it, since repairing the face without closing the top only buys time.

Any crown, cap or cover work is priced on its own line. Our local stone experts in Markham explain the order of the work.

A price written part by part

Stone chimney estimates can hide a lot in one line. Ours name each stone to be reset or replaced, the joints to be repointed, any backing, barrier or weep screed work, and separate items such as flashing or the chase cover. You can see what each part covers and decide what to do now and what can wait.
