Our stone chimney repairs in Westchester
When several stones loosen in one area
A cluster of loose stones usually points to something behind them. The lath may have corroded, the scratch coat may have lost its grip, or water may have soaked the backing over a long period.
In that case we suggest removing the loose group, checking the surface behind it and repairing that surface before any stones go back. Resetting stones one by one over a failing base tends to repeat the problem. The estimate shows the backing repair as its own line, apart from the stone work.
Signs of trouble inside the house
Water getting behind stone on a chimney can show indoors as a damp patch, a stain or bubbling paint on the wall beside the fireplace. On a framed chase, it can appear well below the point where it entered. A ceiling mark close to the chimney can come from the same leak.
Tell us about any interior signs. We check the exterior above them and, where reachable, the attic side. Matching an inside mark with an outside route narrows the repair and keeps the estimate focused on the joints and stones that are actually letting water in.
Matching natural stone
Natural stone varies from one source to another and even within one quarry. Weathered faces also look different from freshly cut ones. A matching stone type can still take time to blend in. In some cases, reusing sound stones from less visible faces gives the better match.
We look for stone of similar color, texture and size, and we set any new pieces where they sit best among the originals. We tell you honestly how close the match is likely to be before any new stone is ordered, so the result is not a surprise.
Stone at the chimney corners
Corners take knocks and weather from two sides. On manufactured stone, corners are often formed with purpose-made corner pieces. On natural stone, corner stones are dressed to show two finished faces. Corners also show a mismatch more than flat faces do, so matching gets extra care there.
A loose or broken corner piece exposes the backing on two sides at once. We check every corner along its height. Replacement corners are matched to the product or shaped to fit, and set in a full bed like any other stone, with the joints tooled to match the faces on either side.
What the stone inspection and estimate include
- Resetting stones in a full mortar bed
- Gentle cleaning of mortar smears
- Hose water test when the job calls for it
- Roots and plants cleared from joints
Answers on repointing chimney stone
How do you tell natural stone from manufactured stone?
Weight, edges, the back of a loose piece and the way joints are laid all give clues. Manufactured stone is a cast product with its color concentrated near the face. We tell you what we believe you have and why.
Can you find replacement stones that match my chimney?
Sometimes exactly, sometimes only closely. Manufactured stone lines change, and natural stone varies by source. Paperwork naming the product helps. We show you options before any new stone goes on the chimney.
Is same-day service available for loose chimney stone?
Same-day service is available when the schedule allows, often to assess a loose stone or make an area safe. Resetting and repointing need curing time, so most stone repairs take more than one visit.
