The thinking behind each stone repair
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.
Caulk and foam left by earlier repairs
Caulk, foam and construction adhesive sometimes appear in stone joints after quick fixes. They seal the surface but not the joint, and they take the place of the mortar that belongs there. Caulk also traps water behind it, which can keep the stone bed wet.
We remove those materials before repointing, so new mortar can fill each joint properly. If adhesive has been used to hold stones, those stones are checked and reset in mortar. The estimate lists that removal work separately, because it can take longer than the repointing itself.
Keeping rain off fresh stone work
Heavy rain on fresh joints can wash mortar out of them and stain the stone below. New setting beds also need time before they are soaked. Fresh joints darken and weaken if rain reaches them too soon.
We watch the forecast and protect fresh work when rain threatens. Opened areas are covered before we leave each evening, and loose stones are stored safely off the roof. If weather interrupts the sequence, we tell you how it changes the plan and when we expect to return. A delayed finish is better than joints that wash out.
New work can look fresh at first
Fresh mortar and newly cut or cleaned stone can look brighter than their weathered surroundings. That difference usually softens as the repair is exposed to sun and rain. Cleaning the surrounding stone lightly can also narrow the difference, where the stone allows it.
We keep it small by reusing stones, matching mortar and cleaning carefully. We also tell you what to expect on the day the work is finished, so a fresher look is not mistaken for a mismatch. If the difference still bothers you after it weathers, tell us and we will look again.

Common questions on stone repair
Why not just glue a loose stone back in place?
Adhesive is not a substitute for a proper mortar bed on an exterior wall. A glued stone can let go again, and the glue can block the drainage behind it. We reset stones the way the assembly was meant to hold them.
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 mortar do you use for repointing stone?
One chosen for the stone and the assembly. For natural stone, the mortar should not be harder than the stone. Manufactured stone follows its maker's guidance. We explain the choice rather than using one mix everywhere.
