Crown does exterior masonry and brick repair on commercial and historic buildings across Greater Boston. We restore facades, chimneys, parapets, and decorative stone so the full exterior lasts.
Full ExteriorBrick, Stone and Mortar
The Full ExteriorMasonry work,
Masonry work,
done properly.
A building's exterior is one system. Failed mortar on a facade, a cracked chimney crown, and a shifted parapet cap all let water into the same walls. Treating them as isolated patches is how small masonry failures become interior damage.
Crown's masonry crews work the full exterior of commercial and historic buildings across Greater Boston. Brick, brownstone, carved stone, and mortar get one crew that already knows the building, from the sidewalk line to the chimneys.
We repoint facades, restore decorative stone, rebuild parapets, and replace chimney crowns as a single documented scope. You get one set of photos, one schedule, and one warranty covering the masonry that actually keeps the building dry.
01
Tuckpointing
Deteriorated mortar joints are the most common source of water infiltration in brick buildings. We repoint facade and chimney joints to the correct profile and depth so water has nowhere to enter.
02
Parapet Wall Repair
Parapet walls take the worst of New England weather. We repair cracked caps, failed coping, and deteriorated masonry before water gets behind the wall and into the floors below.
03
Chimney Cap & Crown Repair
Failed chimney caps and crowns are a fast path to interior water damage. We replace or rebuild them with the right materials and profile so they shed water away from the stack.
04
Facade Restoration
Historic brownstone, carved stone, and commercial brick facades get the same crew as the rest of the exterior. We match mortar, stone, and brick so the repair reads as original.
Warning SignsDon't wait for
Don't wait for
the ceiling stain.
Crumbling or missing mortar
The first indication that tuckpointing is overdue. Water enters joint voids before visible spalling appears.
White deposits on brick faces
Efflorescence is salt drawn out by moisture moving through the masonry. Water is already inside the wall.
Cracks following mortar joints
Straight-line cracking along bed or head joints signals differential movement or freeze-thaw deterioration.
Parapet cap displacement
Shifted or cracked coping allows direct water entry at the roof perimeter - often the source of recurring interior leaks.
Staining below chimney flashing
Rust or dark streaking at the counterflashing line means the seal between masonry and roof membrane has failed.
Interior staining near exterior walls
A stain that appears at an interior wall - not under a roof penetration - is usually a masonry infiltration problem, not a roofing one.

questions,

Often it is both. We conduct a full building envelope assessment - not just a roof walk. If water is entering at the parapet, chimney, or wall-to-roof transition, we trace it through both systems and tell you exactly what is failing before recommending a repair scope.
Tuckpointing is the process of removing deteriorated mortar from brick joints and replacing it with fresh mortar matched to the original profile. Most commercial brick in Greater Boston needs repointing every 20 to 30 years depending on exposure. Signs it is time: crumbling mortar, cracks that follow the joint lines, or white salt deposits (efflorescence) on the face of the brick.
Yes - and we recommend it. The parapet cap, coping, and counterflashing are shared territory between masonry and roofing. Doing them as separate scopes creates the risk of one trade undoing what the other just completed. A single coordinated scope is faster, cheaper, and produces a single warranty.
Yes. Chimney crowns fail regularly on New England buildings - freeze-thaw cycles crack the concrete, mortar, or brick, and failed crowns are one of the fastest paths to interior water damage. We rebuild them with the correct drip-edge profile and materials so they shed water away from the stack rather than funneling it in.
Roof leaking too? We handle both.
Crown coordinates masonry and roofing repairs as a single scope - one crew, one invoice, one warranty.
