Stone chimney repair details for Lockhart homes
How the masons who repoint stone in Lockhart explain the work to neighbors.
Pointing joints when they are thumbprint dry
On manufactured stone, the maker's instructions call for joints to be pointed with a wood stick or metal jointing tool once they are firm, or thumbprint dry. Excess mortar is raked out and the edges around each stone compacted and sealed.
Setting times vary with the wall and the weather, so our crew checks joints by touch instead of by the clock. Even, careful jointing is what makes a repaired area read as part of the original wall.
Removing caulk and sealant from joints
Caulk pressed into stone joints is a common quick fix for a leak. It seals the joint face while water still moves behind it, it stains stone as it ages and it leaves a surface that new mortar will not bond to.
We cut caulk out completely, scrape the residue off the stone edges and rake the joint to sound mortar before repointing. If the caulk was hiding a leak, the leak goes into the findings with its source.
Reaching the upper stones safely
Upper stones, the cap and the roof flashing are reached from the roof or from staging. The roof pitch, the roofing material and the chimney height decide which.
We plan access during the free inspection and protect the roofing around the chimney with pads and tarps. Tools and stones stay off the shingles. The access plan is written into the estimate, so you know what to expect on the day.
What we look at on a stone chimney
We start at ground level with the whole chimney, the base, the screed and clearance on veneer and the runoff around it. From the roof, where access is safe, we check the cap, the upper stones, the joints and the flashing.
Stones within reach are tapped for hollow spots. Stains, white deposits, flaking and earlier patches are noted. Nothing is taken apart at this stage, and the written estimate follows from what we find.
When veneer needs to come off and go back on
Sometimes veneer has failed across a whole chase, with corroded lath, missing barrier layers or trapped water throughout. Resetting stones one by one would leave the real problem in place.
Then the right repair is to remove the veneer, rebuild the barrier, lath and scratch coat to the maker's directions and reinstall the stone, reusing sound pieces. It is a bigger job, and we show you the evidence for it before recommending it.

Quick stonework facts for Lockhart chimneys
Missing your question? Our Lockhart masons will answer it by phone.
Why do you use a softer mortar on stone?
Repointing mortar should be softer and more vapor permeable than the stone around it, so moisture leaves through the joints and any stress is taken by mortar that can be replaced. Mortar that outlasts the stone in hardness tends to push the damage into the stone faces instead.
How long before new stone joints can be cleaned?
New mortar needs time to harden fully before any cleaning beyond a dry brushing. Preservation guidance suggests about thirty days is usually enough before cleaning a freshly repointed wall, depending on weather and exposure. We tell you when it is safe to clean.
