Historic mortar
Lime mortar is used where modern mixes would be too hard so the brick is not damaged by hard mortar.
A Stratford chimney mason can repoint the joints on a weathered chimney, so water stops soaking in between the bricks. One call to (856) 441-8084 reaches a nearby chimney tuckpointing pro.
Mortar is the sacrificial part of a masonry chimney, meant to erode slowly so the brick is spared. Rain, frost and heat gradually wash the mortar out of the joints, leaving them sandy, recessed or open. Open joints let water into the heart of the chimney, where it freezes and pushes bricks out of place.
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. New mortar should be softer than the brick, so Type N or Type S is common on newer chimneys and a lime-rich mix is used on older, softer 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.

Call nowA repointing job that lasts depends on depth, mortar choice and curing.
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. Sand color has a big effect on the final look.
Damaged mortar is removed down to solid material so the new mortar has something to grip. Careful work here keeps the joints from looking widened or ragged.
Joints are cleaned and dampened before any mortar goes in. Proper prep keeps the new mortar from cracking or shrinking away.
New mortar is pressed into the joints in thin layers, letting each firm up before the next. Thin lifts give a dense, solid joint.
When the mortar firms up, the mason tools it to the right profile and cleans the brick face. A tooled joint compresses the mortar surface so it sheds water.
Lime mortar is used where modern mixes would be too hard so the brick is not damaged by hard mortar.
Damaged bricks are swapped while the joints are open before the joints are finished.
All failing joints are replaced so the mortar is uniform from top to bottom.
Damaged areas, often the top courses or the weather side, are repointed while sound mortar is left in place.
New mortar is matched to the old in color, texture and strength so the repair does not stand out.
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.
For Stratford homeowners, the key questions about repointing are mortar type, depth and timing. Make sure the mortar is matched to the brick, the joints are cut to proper depth and the work is protected while it cures. Cold weather makes repointing harder, so plan it outside the depths of winter.
Chimney mortar in Stratford wears fastest on the side that takes the most wind and rain. Across Stratford and nearby places including Somerdale, Lindenwold, Echelon and Magnolia, seasonal rain and freeze-thaw slowly wash out mortar joints on chimneys of every age, which is why tuckpointing on schedule is easier than replacing brick later.

Winters here are long and cold, and the heating season usually runs from October well into April. 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, and each winter widens the cracks a little more. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Stratford 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.
