Masonry Repair
Chimney Masonry Repair Sharon, PA
A chimney sweep in Sharon can repair most masonry damage brick by brick, long before the chimney needs rebuilding, and stop the water that caused the damage. Dial (724) 509-7140 to talk with a local chimney sweep about masonry repair.
Chimney masonry fails mostly because of water and frost. 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.
Masonry repair is as much about the right materials as the right technique. Mortar is meant to be the sacrificial part of the wall, so it is chosen to be softer than the brick, which usually means Type N or Type S, or a lime mortar for older masonry. Getting this wrong leads to fresh cracking within a few seasons.
Before the visit, a little information helps a Sharon chimney sweep plan the work. Mention which part of the chimney looks damaged, whether it is getting worse and whether bits of brick have fallen. If the chimney leans or bricks are loose enough to move by hand, avoid using the fireplace and keep people away from the area below until it is checked.
Chimney Masonry Repair is often paired with chimney tuckpointing and chimney rebuilding, depending on the cause.

The masonry repair process
Here is how a chimney mason typically approaches masonry repair.
Check every face
The masonry is inspected from the roof, with special attention to the top and the weather side. The goal is to find the water source as well as the damage.
Select the mortar
The mason sources brick that blends with the chimney and picks a mortar type suited to it. Type N or Type S mortar suits most chimneys, while very old brick may need a softer lime mortar.
Cut out bad units
Each failed brick is chiseled or cut free. The cavity is cleared of old mortar and debris.
Lay replacement brick
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.
Repair the mortar
Crumbling joints across the chimney are raked out and repointed. This restores strength and keeps water from getting behind the brick.
Stop the water
The crown, cap and flashing are repaired as needed, and a breathable water repellent may be applied once the mortar cures. Non-breathable coatings would undo the repair.
What is included
Types of chimney masonry repair
Efflorescence cleanup
White efflorescence is cleaned off once the water source is fixed so new staining shows if moisture returns.
Damaged brick
Failed bricks are swapped for sound brick without rebuilding the chimney.
Repointing
Joints are repointed in a color that matches the old mortar.
Crack repair
Cracked masonry is rebuilt or stitched before they spread.

Chimney Brick Repair Sharon, PA
Brick repair on a chimney usually means cutting out damaged bricks and setting new ones in fresh mortar. Finding a close match is part of the job, sometimes with salvaged brick for older chimneys. Mismatched brick can absorb water differently and wear unevenly.
For older Sharon homes, brick repair often uses salvaged or reclaimed brick to match the original. 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 Sharon, PA
Spalled brick has lost its outer face, usually because water soaked in and froze. Each spalled brick lets in more water, which spreads the damage. Spalling usually points to a water problem, such as a bad crown or flashing, or to the wrong mortar or a sealer that traps moisture.
In Sharon, fixing spalled brick starts with the water source and ends with new brick. Lightly spalled bricks can sometimes be turned around to show their sound back face, while badly damaged ones are replaced. A vapor-permeable repellent applied after repair helps prevent new spalling.

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, 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 Sharon is usually booked in the fall, before the first cold night.

Common questions about chimney masonry repair
Can damaged chimney bricks be replaced individually?
A few damaged bricks are typically replaced individually. Each damaged brick is cut free and a new one set in its place. If damage is widespread or the chimney is loose or leaning, rebuilding the upper section may be the better option.
Does the type of mortar matter for chimney repair?
The mortar has to be compatible with the brick, which usually means softer than the brick. Most chimneys use Type N or Type S, with lime mortar reserved for older masonry. Hard mortar on soft brick makes the brick fail instead of the joint.
What causes chimney bricks to crumble?
Water and freezing are the main causes. Moisture enters through the crown, flashing or masonry and expands when it freezes. The wrong mortar or a non-breathable coating can make it worse.
How long does chimney masonry repair take?
Both depend on the extent of the damage and on stopping the moisture that caused it. A modest repair may be finished quickly, while extensive work takes longer. Well-matched repairs with the water source fixed last a long time.
Should I seal my chimney bricks after repair?
Applying a siloxane-based repellent once the mortar cures can protect the brick. Breathable repellents block liquid water while letting vapor out. Avoid paint and film-forming sealers, which trap moisture and cause spalling.
