Stone chimney repair in Pershing

Working in hot or dry weather

The same instructions say that in hot or dry weather, the back of each stone should be moistened with a fine spray or wet brush, and a concrete, masonry or scratch coat backing dampened before mortar goes on. Surfaces should look damp but carry no standing water.

Skipping that step lets the stone and backing pull water from the fresh mortar too quickly, weakening the bond. We plan the work and the dampening around the conditions on the day.

Cleaning manufactured stone the gentle way

Dirt on cast stone needs a light touch. The instructions we follow say it can be removed with granulated soap or detergent in water and a bristle brush, rinsed right away with fresh water. They rule out wire brushes, acid or acid-containing products, power washing and sandblasting.

Those methods can strip the colored surface of cast stone and leave marks that do not come out. We clean with the gentle method first and never reach for pressure or acid on manufactured stone.

• Detergent, water and a bristle brush
• Rinse right away with fresh water
• No wire brush, acid, pressure or blasting

Replacing a missing stone

A missing stone leaves the backing or core of the chimney open to rain. We check what is behind the gap first, since damaged backing needs repair before any stone goes back.

If the fallen stone survived, it is cleaned and reset. If not, we look for a replacement close in type, size, color and texture, sometimes from a less visible part of the property or a stone supplier. You see the replacement next to the wall before it is set.

Opening a small area to see behind the stone

Some questions only get answered by looking. With your approval, we remove a few stones in the affected area to see the setting bed, the scratch coat, the lath and the barrier behind them.

That small opening often decides the whole plan, from a simple reset to rebuilding the backing over a larger area. The removed stones are kept, cleaned and reset, and the opening and its price are written into the plan beforehand.

Same-day visits for loose stone

A fallen stone or a piece hanging loose can make you want an answer quickly. Same-day service is available when the schedule allows.

On a same-day visit, we make the area safe first, then inspect the chimney, explain what we see and give you the written estimate as soon as possible. The full repair is scheduled around the weather and your plans.
