Historic mortar
Older chimneys with soft brick are repointed with lime-based mortar so the brick is not damaged by hard mortar.
A Beach Haven chimney mason can repoint the joints on a weathered chimney, so water stops soaking in between the bricks. One call to (609) 991-0383 reaches a nearby chimney tuckpointing pro.
Mortar is the sacrificial part of a masonry chimney, meant to erode slowly so the brick is spared. Wind-driven rain and freeze-thaw cycles break mortar down a little every season until the joints are hollow. At that point the joints stop keeping water out, and the brick around them starts to suffer.
The fix for eroded mortar is tuckpointing, also called repointing. Damaged mortar is ground or raked out, the joints are cleaned and dampened, and new mortar is pressed in firmly and shaped. In the trade, true tuckpointing means filling joints with a brick-colored mortar and then adding a fine ribbon of contrasting mortar, though today the term usually just means repointing.
The single biggest mistake in repointing is using mortar that is too hard. The mix has to be weaker than the brick so stress goes into the joint, which means Type N or Type S for most chimneys and lime mortar for historic brick. Hard, high-strength mortar on soft brick makes the brick edges crack and spall within a few winters.
Chimney Tuckpointing is often paired with chimney masonry repair and chimney waterproofing, depending on the cause.

Each face of the chimney is checked to see how far the joint damage goes. The crown, cap and flashing are checked as well, since they often let in the water that wore out the joints.
A mortar is chosen that is softer than the brick and close to the original in color and texture. Mortar dries lighter than it looks wet, so color is checked carefully.
Failing mortar is ground or raked out to a sound depth, usually about two to two and a half times the joint width. Overcutting into the brick is avoided.
Joints are cleaned and dampened before any mortar goes in. That helps the new mortar cure properly and bond to the old masonry.
Fresh mortar is pushed in firmly, layer by layer, to fill each joint completely. Thin lifts give a dense, solid joint.
Once the mortar is thumbprint hard, the joints are tooled to match the existing profile, such as concave or flush. Concave joints shed water best and are common on chimneys.
Older chimneys with soft brick are repointed with lime-based mortar so the brick is not damaged by hard mortar.
Loose bricks are reset in fresh mortar in the same visit.
The mix and sand are chosen to blend with the existing joints while staying softer than the brick.
Damaged areas, often the top courses or the weather side, are repointed to stop the damage from spreading.
Every worn joint on the chimney is cut out and repointed which restores the entire chimney.
Repointing replaces the worn mortar between chimney bricks with fresh mortar, restoring the joints. Most homeowners and contractors use repointing and tuckpointing to mean the same thing. Good repointing restores the strength and weather resistance of the chimney.
A repointing job in Beach Haven lasts longest when a few basics are done right. Make sure the mortar is matched to the brick, the joints are cut to proper depth and the work is protected while it cures. Since fresh mortar should not freeze, repointing is best scheduled in warmer months.
Chimney mortar in Beach Haven wears fastest on the side that takes the most wind and rain.

Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Beach Haven is usually booked in the fall, before the first cold night.
A chimney problem fixed early rarely spreads to the masonry, the liner or the house.
Chimney sweeps in Beach Haven know the chimneys and fireplaces common in local homes.
Ask the sweep about the cause, the options and the estimate before work starts.
