Masonry Repair
Chimney Masonry Repair Clarendon Hills, IL
A Clarendon Hills chimney technician can repair the brick, stone and mortar of a weathered chimney, before the next winter makes it worse. Dial (331) 301-3221 to talk with a local chimney sweep about masonry repair.
A chimney stands above the roof with no eaves to shelter it, so its brick and mortar soak up rain from every side. Brick and mortar absorb moisture, and when that water freezes it expands and breaks the masonry from the inside, a process called freeze-thaw. Flue heat, settling and the acids in combustion gases speed it up.
Good masonry repair is about matching materials, not just filling holes. 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. Hard, high-strength mortar on soft old brick is one of the most common causes of new damage after a repair.
Before the visit, a little information helps a Clarendon Hills chimney sweep plan the work. Note where the damage is, such as the top courses, the side facing the weather or the area near the roof line, and whether you have found pieces of brick on the roof or ground. Any chimney with loose bricks or a visible lean should be kept out of use and the ground below kept clear.
Chimney Masonry Repair is often paired with chimney tuckpointing and chimney rebuilding, depending on the cause.

What happens during masonry repair
Masonry repair starts with finding out how far the damage goes and why it happened.
Inspect the masonry
The masonry is inspected from the roof, with special attention to the top and the weather side. Without fixing the cause, the damage returns.
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.
Remove damaged brick
Each failed brick is chiseled or cut free. The opening is cleaned so the new brick sits on fresh mortar.
Lay replacement brick
Replacement bricks are buttered and pushed into place, then the joints are finished to blend in. Joint style and mortar color are matched as closely as possible.
Repair the mortar
Failing mortar is removed and replaced in layers. This restores strength and keeps water from getting behind the brick.
Protect the work
Whatever let water in, whether a cracked crown, a missing cap or failed flashing, is fixed so the damage does not return. Non-breathable coatings would undo the repair.
What is included

Chimney Brick Repair Clarendon Hills, IL
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. Brick that is much harder or softer than its neighbors will weather differently and can cause new cracking.
For older Clarendon Hills homes, brick repair often uses salvaged or reclaimed brick to match the original. Mortar is mixed to blend with the existing joints and to be softer than the 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 Clarendon Hills, IL
Spalling is when the face of a brick flakes, pops off or crumbles, and it is almost always caused by water and freezing. Each spalled brick lets in more water, which spreads the damage. Paint and non-breathable coatings are a frequent cause, since they trap moisture behind the brick face.
A lasting spalling repair in Clarendon Hills addresses both the brick and the cause. Some spalled bricks can be removed, flipped and reset if the back is sound, and the rest are replaced with matching brick. A vapor-permeable repellent applied after repair helps prevent new spalling.

What the local climate does to a chimney
This part of the country gets long winters, heavy snow in places and stretches of bitter cold. Furnaces, wood stoves and fireplaces run hard from fall to spring, so flues collect creosote fast and liners and crowns see a lot of heat and cold. Snow that piles up behind a chimney and melts slowly is a common source of leaks at the flashing. That is why Clarendon Hills chimney sweeps are busiest every September and October.

Chimney Masonry Repair FAQ
Why are the bricks on my chimney falling apart?
Most crumbling brick comes from water soaking in and freezing. Water gets in through a cracked crown, failed flashing, open joints or porous brick, then freezes and breaks the brick apart. Paint, sealers and overly hard mortar trap moisture and stress the brick.
Is it a good idea to waterproof chimney brick?
The right product, a breathable repellent, is a good final step. Breathable repellents block liquid water while letting vapor out. Film-forming coatings trap water and can cause the damage they were meant to prevent.
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. 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. Most chimneys use Type N or Type S, with lime mortar reserved for older masonry. Mortar that is too hard forces stress into the brick and causes cracking and spalling.
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. Repairs done with matched materials, with the crown, cap and flashing in good shape, can last many years.
