What's Included
Stone chimney problems we fix in Heathrow
What sits behind manufactured stone
On a framed chimney chase, manufactured stone is the last of several layers. The industry installation guide shows sheathing, then two layers of water-resistive barrier, then metal lath, a scratch coat of mortar and finally the stone in its setting bed. When veneer fails, one of those layers usually failed first, and that is where the repair starts.
We open the affected area and check each layer before any stone goes back. Homeowners in Heathrow get the findings in writing.
Grouting and tooling veneer joints
Joints between manufactured stone units are grouted once the units have taken hold in their setting bed, filled from a grout bag to the depth of the joints around them. The installation guide has the grout left until it is thumbprint hard, then tooled with a wooden raking stick or pointing tool, taking care not to scratch the face of the stone.
Matching the joint depth and texture is what makes a repair blend in. Our local stone pros take that care on veneer repairs in Heathrow.
Sealers and coatings on stone
A shiny coating brushed over stone can change its color and hold moisture in, and a sealer is no fix for open joints or loose units. The veneer installation guide sends every question about repellents and sealers back to the stone's maker. We make repairs first and recommend a coating only where the maker supports one.
If an old coating is causing trouble, we explain what can be done. The inspection by our local stone experts in Heathrow is free.
Flashing against an uneven stone face
Metal flashing has to seal against the chimney where it meets the roof, and an irregular stone face makes that harder than flat brick. A bead of caulk run along the stone is not flashing, and it opens again with the first hot spell. Where the roof junction is leaking, we explain the proper fix and price it separately from the stone work.
This junction gets checked on every stone chimney in Heathrow, and the inspection is free.
Your free stone inspection, face by face
Each face of the chimney is checked for loose, cracked or missing stones, along with the joints, the top, the roof junction and the base of any veneer, and we look inside the house for signs of water. Where we cannot see something without opening the wall, we say so plainly instead of guessing.
Findings come in plain words, with the price in writing. Call (645) 465-4122 to book a free stone chimney inspection in Heathrow.
