Chimney Tuckpointing Park Forest, IL
A Park Forest chimney mason can repoint the joints on a weathered chimney, before loose mortar turns into loose brick. One call to (708) 708-7348 reaches a nearby chimney tuckpointing pro.
On a sound chimney, the mortar is supposed to wear before the brick does. Wind-driven rain and freeze-thaw cycles break mortar down a little every season until the joints are hollow. Once the joints open up, water gets behind the brick, freezes and starts loosening the bricks themselves.
Tuckpointing is the repair for worn joints. The old mortar is cut out to a sound depth, typically about two to two and a half times the width of the joint, and fresh mortar is packed in and tooled. The word technically describes a decorative finish with a narrow contrasting joint, but in everyday use it means replacing worn mortar.
Getting the mortar right matters more than anything else in the job. The mix has to be weaker than the brick so stress goes into the joint, which means Type N or Type S for most chimneys and lime mortar for historic brick. Too-hard mortar forces the brick to crack instead of the joint.
If the problem goes deeper than it first looked, a Park Forest chimney sweep may also recommend chimney masonry repair or chimney waterproofing.

What happens during tuckpointing
Here is how a chimney mason typically tuckpoints a chimney.
Assess the mortar
The joints are probed to find where mortar is sound and where it has failed. Water sources like a cracked crown are noted, because they caused the damage.
Choose the mix
A mortar is chosen that is softer than the brick and close to the original in color and texture. Mortar dries lighter than it looks wet, so color is checked carefully.
Grind out joints
Damaged mortar is removed down to solid material so the new mortar has something to grip. Hand tools are often used near soft or older brick to avoid damage.
Dampen the masonry
The cleared joints are flushed of dust and lightly wetted. That helps the new mortar cure properly and bond to the old masonry.
Fill in layers
New mortar is pressed into the joints in thin layers, letting each firm up before the next. Thin lifts give a dense, solid joint.
Shape the joints
The joints are shaped to match the original style and excess mortar is brushed off the brick. A tooled joint compresses the mortar surface so it sheds water.
What is included

Chimney Repointing Park Forest, IL
Repointing replaces the worn mortar between chimney bricks with fresh mortar, restoring the joints. It is the same job most people call tuckpointing, and it is one of the most common masonry repairs on chimneys. It protects the brick by making the joints the part that wears.
If you are planning repointing on a Park Forest chimney, a few details make the biggest difference. The mortar must be softer than the brick, the old mortar has to be removed deep enough for the new mortar to hold, and the joints need to be packed in layers. Cold weather makes repointing harder, so plan it outside the depths of winter.

How the weather here affects chimneys around Park Forest
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 Park Forest chimney sweeps are busiest every September and October.

Chimney Tuckpointing questions
Is tuckpointing the same as repointing?
In everyday use the two words mean the same thing: removing worn mortar and replacing it with new mortar. The traditional meaning of tuckpointing is a finish that uses two mortar colors. For a chimney, what you need is sound, watertight joints.
Can the wrong mortar damage chimney brick?
When new mortar is stronger than the brick, the brick takes the stress and fails. Mortar is supposed to be the weaker, sacrificial part of the wall. Older, softer brick usually needs a lime mortar.
Can I tuckpoint my own chimney?
Chimney repointing involves roof work, fall risk and careful material choices. The most frequent errors are hard mortar, shallow joints and chipped brick. A chimney mason can also spot crown, flashing and flue problems while up there.
When is the best time to tuckpoint a chimney?
Warmer months are the best time for mortar work. Mortar cures best in moderate temperatures. Getting it done before heating season also means the chimney is ready when you need it.
How long does chimney tuckpointing last?
Well-done tuckpointing with the right mortar can last for decades. How long it lasts depends on weather exposure, the mortar used and whether the crown, cap and flashing keep water out. Having the chimney inspected each year spots worn joints early.
