Chimney Repair in Palos Heights, IL — Rebuilt to Last

Stand in your Palos Heights backyard after a hard rain and look up at the chimney. If the mortar joints near the top look washed out and sandy, if the crown on top is cracked, or if the brick above the roofline is flaking and leaning even slightly, you are looking at the part of your house that fails first — and the part that lets water in fastest when it does.

Paul Lally's Masonry provides chimney repair in Palos Heights, IL — repairing crowns, caps, flashing, and failed mortar joints, and rebuilding chimneys above the roofline when the brick is past saving. We are family-owned and have served Chicagoland since 1988. For a free on-site estimate, call (708) 448-8866.

Why the chimney is always the first thing to go

Every other masonry surface on your home gets some shelter — from the roof overhang, from neighboring walls, from the ground. The chimney gets none of it. It stands alone above the roofline, exposed on all four sides to sun, wind-driven rain, and the freeze-thaw swings that define a Cook County winter. That is why, on the mid-century and newer brick homes around Palos Heights and the Lake Katherine area, the chimney is almost always the first masonry to show real damage.

The failure follows a predictable path. Water finds a cracked crown or an open mortar joint. It soaks into the brick and mortar, then freezes and expands. The next thaw lets more water in, and the cycle repeats — sometimes several times in a single week. Each cycle widens the cracks a little more until the crown breaks apart, the joints open up, and the brick face begins to spall.

The four parts we actually check

A chimney is not one thing — it is a small system, and a real repair looks at all of it rather than patching the most obvious spot.

The crown

The crown is the sloped cap on top that sheds water away from the flue and the brick. When it cracks — and old mortar-washed crowns almost always do — water runs straight down into the masonry below. We rebuild or recast crowns with a proper slope and overhang so the top of your chimney actually throws water clear of the brick.

The mortar joints

Above the roofline, the mortar takes the worst of the weather. We grind out the failed joints to depth and repoint them with color- and type-matched mortar, the same careful tuckpointing and repointing approach we use on walls — because a skim-coat over old joints on a chimney peels off in the first hard Palos Heights winter.

The flashing

The flashing is the metal seal where the chimney passes through the roof. A surprising number of "chimney leaks" are actually flashing leaks. We check it as part of the job so we address the real source of water, not just the nearest brick.

The cap

The cap is the screen-and-cover unit over the flue opening that keeps rain, animals, and debris out. A missing or rusted cap is an open invitation for water and nesting. It is a small fix that prevents big ones.

When repair becomes a rebuild

Not every chimney can be saved with tuckpointing and a new crown, and we will tell you plainly when it can't. A chimney needs to be rebuilt — usually from the roofline up — when:

• The brick above the roof is spalling, with faces flaking off
• The stack is leaning or visibly out of plumb
• Whole sections of mortar are gone and you can see daylight through the joints
• Previous cheap patches have failed and the damage is now structural

When we rebuild, we take the chimney down to sound masonry and lay it back up with matched brick, a solid crown, and correct flashing. It comes back straight, dry, and built to outlast the repair it replaced.

Our process, start to finish

1. Inspect the whole system. Crown, joints, brick, flashing, and cap — from the ground and up close where access allows.
2. Diagnose honestly. We tell you whether it is a repair or a rebuild, and why.
3. Match materials. Brick matched for size, color, and texture; mortar matched for color, sand, and profile.
4. Do the work to depth. Joints ground out and repacked, crowns recast with proper slope, flashing sealed, cap set.
5. Clean down and walk it with you. You see exactly what changed.

What drives the cost of chimney repair in Palos Heights

We never quote a chimney sight unseen, because the factors that move the price are all things we have to see on the roof:

• Height and roof access — a steep or tall roof needs more staging and safety setup
• Repair vs. rebuild — spot tuckpointing is a fraction of the scope of a full rebuild above the roofline
• Crown and flashing condition — recasting a crown and reflashing add scope
• Brick matching — sourcing a close match for older brick takes more care
• Extent of spalling — badly deteriorated brick has to be replaced, not repointed

We explain every one of these on-site, and the estimate is free. For the number on your chimney, call (708) 448-8866.

Palos Heights homes we work on

Palos Heights runs from mid-century brick ranches near the older neighborhoods to newer custom homes on the wooded lots around Lake Katherine and the forest preserve edge. The taller, more exposed chimneys on those newer two-story homes take a real beating from the wind, while the older masonry chimneys often have soft original brick that needs a softer, matched mortar — not hard modern cement that would spall the brick. As a Palos Heights–based company, we know the local building stock because we have worked on it since 1988.

Paul Lally's Masonry is a family-owned, licensed and insured masonry contractor serving Chicago and the Chicagoland suburbs since 1988 — tuckpointing, brick repair and replacement, chimney repair and rebuilds, lintel replacement, masonry restoration, and waterproofing for residential and commercial properties.
