A stain that points back to the joints
Ceiling or wall stains near a chimney can come from several places. Open mortar joints are one of them, because water that gets into the wall can travel down inside it and appear far from where it entered.
We check the joints alongside the other water paths, so repointing is not sold as a leak fix when the real source is somewhere else. Where the joints are part of the problem, their repair goes on the estimate with the other items. Water stain near the chimney in Brentwood? Call (904) 920-5495 for a free inspection.

How chimney tuckpointing runs
-
Every face surveyed
Joints are scratch-tested at several heights and the failed courses marked on a sketch.
-
Joints raked and cleaned
Old mortar comes out to sound depth, head joints by hand, then joints are cleaned and dampened.
-
Filled in layers and tooled
Matched mortar goes in stage by stage, then is tooled to the original profile.
-
Cured and cleaned up
Fresh joints are protected while they cure, the faces brushed and the roof cleared.
Cleaning old mortar haze in Brentwood
Gray haze left on brick by an earlier repointing is a workmanship problem, not a local one.
On Brentwood chimneys we test the gentlest cleaning method on a small patch before treating a whole face.
10% off any service booked within 72 hours of inspection
For a home in Brentwood with several faces to repoint, every face booked in the 72 hours is discounted.
How deep worn mortar is raked out
National Park Service Preservation Brief 2 ties raking depth to joint width. Take a joint 3/8 inch wide: its old mortar comes out at least 3/4 inch deep, roughly double its width or a little beyond, and deeper again where it is still loose. For typical brick joints, that lands around half an inch to an inch.
Too shallow, and the new mortar sits as a thin skin that falls out. Too deep without cause, and bricks lose support. We rake to sound mortar, square the back of the joint so the new fill has a flat surface to bond against, and check depth as we go rather than trusting one measurement.
Mortar types under ASTM C270
ASTM C270 is the standard specification for mortar for unit masonry. Its four mortar types run M, S, N, O in falling order of strength, defined either by the mix of binder and sand or by lab-tested properties.
The type for a repointing job is chosen from the brick, the exposure and what is already in the wall, not by habit. A chimney of hard modern brick and one of soft old brick will not get the same mortar. The type is written on the estimate, which tells any future mason exactly what fills these joints.
Lime-rich mortar in older chimneys
Chimneys built generations ago often used mortar with much more lime and less cement than modern mixes. Lime mortar is softer and more vapor permeable, and the soft old brick around it was built to work with it.
Preservation Brief 2 advises matching the old mortar's properties when repointing historic masonry. On an older chimney we look at the existing mortar before choosing a mix, and where it is lime-rich, the new mortar follows suit rather than jumping to a strong cement mix. The estimate names the mix chosen. A lime-rich mix also cures more slowly, and the schedule on the estimate allows for that.
What goes on a repointing sketch in Brentwood
- Faces and courses needing repointing, marked on a sketch of the chimney
- Head joints cut by hand, and where a grinder is used
- Interior or attic joints, with their own access and cleanup
- Weather protection and curing for the new joints
Before the joints are raked
How close will the new mortar color be?
A sample batch is mixed, cured beside your brick and checked in daylight before any joint is filled. New joints can still look slightly fresher at first, and we show you the sample so you know what to expect.
Could the cracks simply be caulked?
Caulk or a thin skim over worn mortar has nothing solid to grip and falls away, often hiding deeper failure while it lasts. Raking and refilling the joint is the repair that holds.
