Tuckpointing in Tinley Park, IL — Mortar Joint Repair That Lasts

Drag a house key along the mortar joints on the weather-facing wall of your Tinley Park home. If the mortar crumbles into sand, or the joint has already sunk below the face of the brick, the material holding your wall together is wearing out — and water is finding its way in behind the brick.

Paul Lally's Masonry Inc. provides tuckpointing in Tinley Park, IL — grinding out failed mortar joints to depth and repointing with color- and type-matched mortar so your brick is protected for decades, not seasons. We are family-owned and have served Chicagoland since 1988. For a free on-site estimate, call (708) 448-8866.

What tuckpointing actually does

A brick wall isn't held together by the brick — it's held together by the mortar between the bricks. Mortar is the sacrificial, weather-facing part of the wall: it is meant to wear before the brick does. After decades of south-suburban winters, those joints erode, crack, and pull away from the brick face.

Tuckpointing — also called repointing — is the repair that renews them. A mason grinds the old, failed mortar out of each joint to a proper depth, then packs in fresh mortar matched to the original in color, texture, and profile. Done right, the wall sheds water again and the new work blends into the original masonry instead of standing out as a patch.

Why Tinley Park brick fails

Tinley Park sits across the Cook–Will county line, and its housing runs from 1960s and '70s brick bungalows and ranches near the older village core to the brick-front Georgians and split-levels of the subdivisions that filled in through the '80s and '90s. Two things put that brick at risk:

• Freeze-thaw cycling. Water gets into open joints, freezes, expands, and pries the wall apart a fraction at a time. Over enough winters the brick faces begin to spall.
• The wrong mortar on older brick. A lot of soft mid-century brick was later "repaired" with hard Portland-heavy mortar. Hard mortar traps moisture and forces it out through the softer brick, accelerating spalling. Matching mortar strength to the brick matters as much as matching the color.

Signs your wall needs attention

• Mortar you can rake out with a key or that has receded below the brick face
• Hairline gaps where the mortar meets the brick
• Sandy mortar dust collecting at the base of the wall
• White, chalky efflorescence or damp patches on the interior side
• Individual brick faces beginning to flake or pop off

If you're seeing that last one, the window for simple tuckpointing is closing — spalled brick has to be replaced, which is a bigger job than renewing mortar.

How we tuckpoint in Tinley Park

We grind each failed joint to roughly twice its width in depth, clear the dust, and repoint with mortar matched to your wall's color, sand, and profile — and matched in type to your brick. We tool the joints to match the original profile so the finished wall reads as original, then clean down the face. On chimneys, we handle the crown, cap, and flashing while we're up there, since those fail alongside the joints.
