Lime mortar repointing
Historic masonry gets a softer, compatible mortar so the brick is not damaged by hard mortar.

Chimney Tuckpointing Steger, IL
A chimney sweep in Steger can grind out crumbling mortar joints and refill them with fresh mortar matched to the brick, before loose mortar turns into loose brick. Dial (708) 708-7359 to talk with a local chimney sweep about the mortar.
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. Open joints let water into the heart of the chimney, where it freezes and pushes bricks out of place.
Tuckpointing replaces the worn mortar without disturbing the brick. A mason removes the failing mortar to solid material, packs new mortar into the joint in layers and finishes it to match the existing profile. In the trade, true tuckpointing means filling joints with a brick-colored mortar and then adding a fine ribbon of contrasting mortar, though today the term usually just means repointing.
Mortar choice decides whether tuckpointing helps or hurts. New mortar should be softer than the brick, so Type N or Type S is common on newer chimneys and a lime-rich mix is used on older, softer brick. Hard, high-strength mortar on soft brick makes the brick edges crack and spall within a few winters.
Chimney Tuckpointing is often paired with chimney masonry repair and chimney waterproofing, depending on the cause.

Call nowThe process
The tuckpointing process
Good tuckpointing is slow, careful work, and most of the quality is in the prep.
Assess the mortar
The joints are probed to find where mortar is sound and where it has failed. The crown, cap and flashing are checked as well, since they often let in the water that wore out the joints.
Choose the mix
The mix is matched to the brick, usually Type N or Type S, or a lime mortar for older brick. Mortar dries lighter than it looks wet, so color is checked carefully.
Remove old mortar
Failing mortar is ground or raked out to a sound depth, usually about two to two and a half times the joint width. Overcutting into the brick is avoided.
Dampen the masonry
The cleared joints are flushed of dust and lightly wetted. Proper prep keeps the new mortar from cracking or shrinking away.
Repoint the joints
New mortar is pressed into the joints in thin layers, letting each firm up before the next. Thin lifts give a dense, solid joint.
Tool 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.

Chimneys in this climate
Winters here are cold and long, with lake effect snow in many towns and deep cold snaps that can last for days. Furnaces, wood stoves and fireplaces run hard from fall to spring, which means fast creosote buildup and a lot of stress on liners, crowns and flashing. Snow drifting against the back of a chimney melts slowly and works water under tired flashing. Most chimney cleaning in Steger, IL happens right before the first snow.

Chimney Tuckpointing FAQ
Can I tuckpoint my own chimney?
Chimney repointing involves roof work, fall risk and careful material choices. It is easy to make the joints worse by using the wrong mortar or grinding into the brick. A chimney mason can also spot crown, flashing and flue problems while up there.
What is the difference between tuckpointing and repointing?
Most people use tuckpointing and repointing interchangeably to describe replacing worn mortar joints. The traditional meaning of tuckpointing is a finish that uses two mortar colors. For a chimney, what you need is sound, watertight joints.
What season is best for chimney repointing?
Mild, dry weather is ideal for repointing. Mortar cures best in moderate temperatures. Scheduling before winter protects the chimney through the cold months.
How long does chimney tuckpointing last?
Repointing with matched mortar holds up for many years. Exposure, mortar choice and water control decide its lifespan. An annual chimney inspection is the best way to catch joints before they fail.
Can the wrong mortar damage chimney brick?
Hard modern mortar on soft brick is a common cause of brick damage after a repair. Mortar is supposed to be the weaker, sacrificial part of the wall. For older brick, a lime-based mortar is often the right choice.
