Masonry Repair
Chimney Masonry Repair Bryn Mawr, PA
A Bryn Mawr chimney technician can repair the brick, stone and mortar of a weathered chimney, and stop the water that caused the damage. One call to (484) 380-7228 reaches a nearby chimney masonry pro.
A chimney stands above the roof with no eaves to shelter it, so its brick and mortar soak up rain from every side. Water that soaks into brick freezes and expands, popping off the face of the brick and loosening mortar a little more every winter. Flue heat, settling and the acids in combustion gases speed it up.
The key to masonry repair that lasts is using materials that suit the existing brick. Replacement brick should match the old brick in size, color and hardness, and mortar should always be softer than the brick so the joints wear instead of the brick. Getting this wrong leads to fresh cracking within a few seasons.
Before the visit, a little information helps a Bryn Mawr chimney sweep plan the work. Say where you see flaking brick or crumbling joints, and whether the chimney leaks or leans. Any chimney with loose bricks or a visible lean should be kept out of use and the ground below kept clear.
Many chimney masonry repair calls in Bryn Mawr also turn up a need for chimney tuckpointing or chimney rebuilding.

The masonry repair process
Here is how a chimney mason typically approaches masonry repair.
Inspect the masonry
The technician checks each face of the chimney for spalled brick, failing joints, cracks and loose courses. Without fixing the cause, the damage returns.
Choose brick
Replacement brick is matched to the original in size, color and hardness, and mortar is chosen to be softer than the brick. The mortar color is matched as closely as possible.
Cut out bad units
Each failed brick is chiseled or cut free. The space is prepared for the new unit.
Rebuild the face
The mason sets matching brick and tools the joints to match the rest of the chimney. Done well, the repair is hard to spot from the ground.
Tuckpoint
Failing mortar is removed and replaced in layers. Repointing is often the biggest part of a masonry repair.
Stop the water
With the masonry repaired, the water source is closed off, often with a vapor-permeable repellent as a final step. Non-breathable coatings would undo the repair.

Chimney Brick Repair Bryn Mawr, PA
Brick repair on a chimney usually means cutting out damaged bricks and setting new ones in fresh mortar. A good brick repair blends in, which means matching the size, color and texture of the original brick. A poor match shows up as uneven weathering over time.
In Bryn Mawr, older chimneys may need reclaimed brick to blend in. The mortar is matched too, both in color and in strength, so it does not damage the old brick. If a large area is damaged, partial rebuilding of the top section may be more practical than replacing brick one at a time.

Spalling Brick Repair Bryn Mawr, PA
Spalled brick has lost its outer face, usually because water soaked in and froze. Once a brick has spalled, it absorbs water faster and deteriorates more quickly, so the damage speeds up. Paint and non-breathable coatings are a frequent cause, since they trap moisture behind the brick face.
A lasting spalling repair in Bryn Mawr addresses both the brick and the cause. Badly spalled bricks are cut out and replaced, and the mason may reverse lightly damaged ones. After repairs, a breathable water repellent can help the masonry shed water without trapping moisture.

Chimneys in this climate
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 Bryn Mawr is usually booked in the fall, before the first cold night.

Chimney Masonry Repair questions
Is it a good idea to waterproof chimney brick?
Applying a siloxane-based repellent once the mortar cures can protect the brick. Vapor-permeable products let the brick dry out. Avoid paint and film-forming sealers, which trap moisture and cause spalling.
Do I have to rebuild the chimney to fix a few bad bricks?
Individual bricks can usually be cut out and replaced without rebuilding the chimney. The mason removes the damaged brick, cleans the opening and sets a matching brick in fresh mortar. When large areas are damaged, a partial rebuild can make more sense.
Does the type of mortar matter for chimney repair?
Matching the mortar to the brick is one of the most important parts of the repair. Modern brick usually takes Type N or Type S, and historic brick often calls for a lime mortar. Using mortar that is too strong damages the brick over time.
How long will my chimney masonry repair last?
Scope and the cause of the damage decide both. Small repairs are fairly quick, and larger jobs depend on the weather because mortar needs to cure. With the cause fixed and the right mortar, masonry repairs hold up for years.
Why are the bricks on my chimney falling apart?
Freeze-thaw cycles do most of the damage. Absorbed water freezes inside the brick and pushes its face off. Hard mortar on soft brick and paint or sealers that trap moisture also cause crumbling.
