Masonry Repair
Chimney Masonry Repair Elkridge, MD
A Elkridge chimney technician can repair the brick, stone and mortar of a weathered chimney, and stop the water that caused the damage. Dial (443) 899-3078 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. Settling foundations and heat from the flue contribute as well.
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. Using the wrong mortar can make a repair cause more harm than the original damage.
Before the visit, a little information helps an Elkridge chimney sweep plan the work. Say where you see flaking brick or crumbling joints, and whether the chimney leaks or leans. Loose or leaning masonry can fall, so keep the area below clear and hold off on fires until it is inspected.
Chimney Masonry Repair is often paired with chimney tuckpointing and chimney rebuilding, depending on the cause.

Call nowThe process
The masonry repair process
A durable repair fixes the damage and the water problem behind it.
Assess the damage
The technician checks each face of the chimney for spalled brick, failing joints, cracks and loose courses. Finding why the masonry failed matters as much as finding where.
Choose brick
Replacement brick is matched to the original in size, color and hardness, and mortar is chosen to be softer than the brick. Older soft brick often needs a lime-based mortar instead of a hard modern mix.
Remove damaged brick
Damaged bricks are removed by grinding out the surrounding joints. 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. Joint style and mortar color are matched as closely as possible.
Tuckpoint
Failing mortar is removed and replaced in layers. Repointing is often the biggest part of a masonry repair.
Stop the water
The crown, cap and flashing are repaired as needed, and a breathable water repellent may be applied once the mortar cures. Paint and film-forming sealers are avoided because they trap moisture in the brick.

Chimney Brick Repair Elkridge, MD
When individual bricks crack, spall or come loose, they can be replaced without rebuilding the whole chimney. 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.
In Elkridge, 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 Elkridge, MD
Spalling is when the face of a brick flakes, pops off or crumbles, and it is almost always caused by water and freezing. Once a brick has spalled, it absorbs water faster and deteriorates more quickly, so the damage speeds up. Common causes include a cracked crown, missing cap, failed flashing, hard mortar on soft brick and non-breathable sealers or paint.
Spalling brick repair on an Elkridge chimney means replacing the damaged bricks and fixing whatever let the water in. Lightly spalled bricks can sometimes be turned around to show their sound back face, while badly damaged ones are replaced. Applying a siloxane-based repellent once the repair cures gives the brick extra protection.

How the weather here affects chimneys around Elkridge
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: rain and melting snow soak into the crown and joints, then freeze and push them apart, 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 Elkridge is usually booked in the fall, before the first cold night.

Chimney Masonry Repair questions
Do I have to rebuild the chimney to fix a few bad bricks?
Replacing damaged bricks one at a time is a common, practical repair. Each damaged brick is cut free and a new one set in its place. Extensive damage or loose masonry may call for rebuilding instead.
What type of mortar is used for chimney repair?
Matching the mortar to the brick is one of the most important parts of the repair. Most chimneys use Type N or Type S, with lime mortar reserved for older masonry. Using mortar that is too strong damages the brick over time.
What causes chimney bricks to crumble?
Water and freezing are the main causes. Water gets in through a cracked crown, failed flashing, open joints or porous brick, then freezes and breaks the brick apart. Hard mortar on soft brick and paint or sealers that trap moisture also cause crumbling.
Is it a good idea to waterproof chimney brick?
The right product, a breathable repellent, is a good final step. Vapor-permeable products let the brick dry out. Avoid paint and film-forming sealers, which trap moisture and cause spalling.
How long will my chimney masonry repair last?
Both depend on the extent of the damage and on stopping the moisture that caused it. Replacing a few bricks or repointing a section is often quick, while larger repairs take longer and need dry weather. With the cause fixed and the right mortar, masonry repairs hold up for years.
