Chimney Masonry Repair Steger, IL
A Steger chimney technician can repair the brick, stone and mortar of a weathered chimney, and stop the water that caused the damage. Dial (708) 708-7359 to talk with a local chimney sweep about masonry repair.
The brick and mortar on a chimney take more weather than any wall of the house, and water is what wears them down. Water that soaks into brick freezes and expands, popping off the face of the brick and loosening mortar a little more every winter. Heat from the flue, acidic exhaust and the house settling add their own wear.
Masonry repair is as much about the right materials as the right technique. Mortar that is harder than the surrounding brick forces stress into the brick and makes it crack and spall, so Type N or Type S mortar is common, with softer lime-based mixes for older, softer brick. Hard, high-strength mortar on soft old brick is one of the most common causes of new damage after a repair.
It helps to note what you have seen before you call. Say where you see flaking brick or crumbling joints, and whether the chimney leaks or leans. 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.
If the problem goes deeper than it first looked, a Steger chimney sweep may also recommend chimney tuckpointing or chimney rebuilding.

Call nowThe process
What happens during masonry repair
Masonry repair starts with finding out how far the damage goes and why it happened.
Assess the damage
Every side of the chimney is examined, along with the crown, flashing and flue. Finding why the masonry failed matters as much as finding where.
Match the materials
The mason sources brick that blends with the chimney and picks a mortar type suited to it. Older soft brick often needs a lime-based mortar instead of a hard modern mix.
Remove damaged brick
Spalled, cracked or loose bricks are carefully cut out without disturbing the sound brick around them. 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.
Tuckpoint
Crumbling joints across the chimney are raked out and repointed. Fresh joints shed water and hold the brick firmly.
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.

Chimney Brick Repair Steger, IL
Chimney brick repair covers everything from replacing a few damaged bricks to rebuilding a section of the chimney face. 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 Steger 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. Extensive damage near the top sometimes makes a partial rebuild the sensible option.

Spalling Brick Repair Steger, IL
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. Paint and non-breathable coatings are a frequent cause, since they trap moisture behind the brick face.
A lasting spalling repair in Steger addresses both the brick and the cause. 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
This part of the country gets long winters, heavy snow in places and stretches of bitter cold. Heating systems and wood stoves work nearly nonstop for months, which means fast creosote buildup and a lot of stress on liners, crowns and flashing. Snow that piles up behind a chimney and melts slowly is a common source of leaks at the flashing. Most chimney cleaning in Steger, IL happens right before the first snow.

Chimney Masonry Repair questions
Why are the bricks on my chimney falling apart?
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. Paint, sealers and overly hard mortar trap moisture and stress the brick.
Is it a good idea to waterproof chimney brick?
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.
Can damaged chimney bricks be replaced individually?
Individual bricks can usually be cut out and replaced without rebuilding the chimney. The process removes only the bad bricks and leaves sound masonry alone. Extensive damage or loose masonry may call for rebuilding instead.
How long does chimney masonry repair take?
Scope and the cause of the damage decide both. Replacing a few bricks or repointing a section is often quick, while larger repairs take longer and need dry weather. Well-matched repairs with the water source fixed last a long time.
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. Mortar that is too hard forces stress into the brick and causes cracking and spalling.
