Stone, mortar and water, handled in order
Stones flaking away in layers
Some natural stones split along their layers when water gets into them, and the face then flakes off in sheets. Hard mortar around a soft stone can make this worse, because moisture escapes through the stone rather than the joint.
We look at how deep the flaking goes. A stone with a sound core may be left in place, turned or dressed back. A badly damaged one is replaced with a matched piece. We also look at the joints around it, since they may be part of the cause.
Stone adhered to block or concrete
Adhered stone can go directly onto clean block or concrete. The installation guide says those surfaces must be free of sealers, paint and form release agents, or lath is needed so the mortar has something to grip. Any coating found on the block is removed or covered with lath before stones go back.
When stones fall from a masonry surface, we check what that surface was like underneath. A painted or sealed wall may explain the failure. The repair then starts with preparing the surface properly, whether by cleaning it back or adding lath, before any stone is set again.
Curing new mortar properly
Mortar needs moisture to cure well. The stone installation guide recommends moist curing of the scratch coat and describes extra care in hot weather, such as shading the work and misting the wall.
We plan the work around the conditions on the day and keep fresh mortar damp as it cures. On hot, sunny faces that can mean starting earlier or working in shorter stretches. Mortar that dries too fast cracks and loses its grip on the stone, so curing is part of the job, not waiting time.
Resetting a whole stone face instead of spots
Spot repairs suit a stone face that is mostly sound. When stones are loose across much of a face, or the backing is failing widely, removing and resetting the whole face can be the steadier option. A full reset also gives a chance to renew the barrier and drainage details across the whole face.
We show both options when both are realistic. The estimate prices the full face and the spot repairs separately, so you can compare cost, appearance and the likely life of each. Whichever you choose, the backing gets the same attention before stones go back.
What the stone inspection and estimate include
- Cleaning stone backs and setting surfaces
- Corroded ties noted and addressed
- Clearance kept between stone and roofing
- Removal of caulk, foam and failed patches
Stone chimney repair questions
Will new mortar joints match the old ones?
We match color, texture and joint profile as closely as materials allow and judge samples once they are dry. New joints can look fresher at first and tend to settle in as they weather.
What should I mention when I call about stone damage?
Say which stones moved or fell, where they are, whether the area gets wet after rain and any past repairs. If you know the stone product or who installed it, mention that too.
Why did stones on my chimney come loose?
Common causes include poor mortar coverage behind the stones, water in the backing, corroded lath or ties, and movement. The stone that came off often shows which cause applies, so we look closely at its back.
