Brick replacement
Loose bricks are reset in fresh mortar so the chimney is solid again.
Worn, sandy or missing mortar on a Clarendon Hills chimney can be repaired by tuckpointing, long before the brick itself starts to fail, before loose mortar turns into loose brick. Dial (331) 301-3221 to talk with a local chimney sweep about the mortar.
Mortar is the sacrificial part of a masonry chimney, meant to erode slowly so the brick is spared. Wind-driven rain and freeze-thaw cycles break mortar down a little every season until the joints are hollow. At that point the joints stop keeping water out, and the brick around them starts to suffer.
The fix for eroded mortar is tuckpointing, also called repointing. 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. Strictly speaking, tuckpointing is an old technique that adds a thin contrasting line of mortar to make joints look crisp, but most people use the word for any repointing job.
Mortar choice decides whether tuckpointing helps or hurts. Mortar is chosen to suit the brick, often Type N or Type S, and a softer lime mortar when the brick is old and soft. Too-hard mortar forces the brick to crack instead of the joint.
Depending on what the sweep finds, chimney tuckpointing in Clarendon Hills, IL can go hand in hand with chimney masonry repair and chimney waterproofing.

The mason checks how deep the mortar has failed, which faces are worst and whether any bricks are loose or damaged. The crown, cap and flashing are checked as well, since they often let in the water that wore out the joints.
The mason picks a mortar type and color that suit the existing masonry. Sand color has a big effect on the final look.
Failing mortar is ground or raked out to a sound depth, usually about two to two and a half times the joint width. Careful work here keeps the joints from looking widened or ragged.
The cleared joints are flushed of dust and lightly wetted. Proper prep keeps the new mortar from cracking or shrinking away.
Fresh mortar is pushed in firmly, layer by layer, to fill each joint completely. Packing in layers prevents voids and shrinkage cracks.
The joints are shaped to match the original style and excess mortar is brushed off the brick. Concave joints shed water best and are common on chimneys.
Loose bricks are reset in fresh mortar so the chimney is solid again.
Lime mortar is used where modern mixes would be too hard that matches the original construction.
The worst sections are tuckpointed with mortar matched to the surrounding joints.
The whole chimney is repointed when wear is widespread so the mortar is uniform from top to bottom.
Mortar is tinted and mixed to match so the repair does not stand out.
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. Done well, it keeps water out and holds the bricks firmly in place for many years.
A repointing job in Clarendon Hills lasts longest when a few basics are done right. Ask what mortar type will be used, how deep the joints will be cut and how the new mortar will be finished. Since fresh mortar should not freeze, repointing is best scheduled in warmer months.
Chimney mortar in Clarendon Hills wears fastest on the side that takes the most wind and rain.

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, so flues collect creosote fast and liners and crowns see a lot of heat and cold. Snow drifting against the back of a chimney melts slowly and works water under tired flashing. That is why Clarendon Hills chimney sweeps are busiest every September and October.
A chimney problem fixed early rarely spreads to the masonry, the liner or the house.
Local sweeps see the same chimney types and weather wear across Clarendon Hills and nearby towns.
Ask the sweep about the cause, the options and the estimate before work starts.
