Tuckpointing in Lisle, IL — Mortar Joint Repair That Lasts

Most Lisle homeowners never think about the mortar between their bricks until a landscaper points out the sandy grit piling up along the foundation, or a home inspector flags "open joints" during a sale. By then the joints have usually been failing for a couple of winters. The good news is that mortar is designed to be renewed — that is what tuckpointing is — and doing it before the brick suffers is the cheapest way to protect a brick home.

Paul Lally's Masonry provides tuckpointing in Lisle, IL — grinding out failed mortar joints to depth and repointing with color- and type-matched mortar so the repair protects your brick for decades. We are family-owned and have served Chicagoland since 1988. For a free on-site estimate, call (708) 448-8866.

Mortar is the part that is supposed to wear

A brick wall is not held together by the brick — it is held together by the mortar joints between the bricks. Mortar is the sacrificial, weather-facing layer of the wall; it is engineered to erode before the brick does, so it takes the abuse and the brick stays sound. Over the decades that job wears it out. In the mix of brick colonials, split-levels, and ranches that fill Lisle's Arboretum Village neighborhoods, that is exactly the kind of aging mortar we are called to renew.

Tuckpointing, also called repointing, is the repair. A mason grinds the 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 repair blends in instead of standing out as a patch.

The signs a Lisle wall is ready for tuckpointing

You can usually read the wall from the ground:

• Mortar you can rake out with a key, screwdriver, or fingernail
• Receding joints where the mortar sits below the brick face
• Sandy mortar dust collecting on sills and at the base of the wall
• Hairline cracks running along the mortar lines
• White efflorescence — a chalky bloom showing water is moving through the wall
• Damp or musty interior spots on an exterior brick wall

On Lisle homes the south and west elevations and the chimney almost always fail first, because they take the most sun, wind-driven rain, and freeze-thaw cycling.

Why DuPage County winters are hard on mortar

Chicagoland masonry lives through dozens of freeze-thaw cycles each winter, and Lisle is no exception. A failing joint lets water into the wall; that water freezes and expands roughly nine percent; the expansion pushes the joint and brick apart; it thaws and the cycle repeats. Each round widens the joint a little more until water saturates the brick and the next freeze pops its hard face off. That is spalling — and spalled brick has to be replaced, not patched. Tuckpointing the joints before that happens is the single cheapest thing a Lisle homeowner can do for a brick house.

How we tuckpoint — the right way, not the fast way

The difference between a repair that lasts and one that peels off in a season is all in the preparation:

1. Grind and rake the joints to depth. We cut the failed mortar out to roughly twice the joint's width, down to sound mortar, so the new material has something to bond to.
2. Clean the joints. Dust and loose debris are brushed and blown out so fresh mortar bonds to brick, not grit.
3. Mix matched mortar. We match color, sand, and texture — and the correct mortar type for your brick.
4. Pack and tool the joints. Mortar is packed tight in layers and tooled to your existing joint profile so the repair disappears.
5. Cure and clean down. The mortar cures properly and the brick face is cleaned, leaving a wall that sheds water and looks original.

A cut-rate "skim job" skips step one — smearing mortar over the old joints without grinding anything out. It looks clean until the first hard Lisle winter, then fails.

Matching mortar strength to your brick

Mortar matching is about more than color. Type N mortar is a medium-strength, more flexible mix and the right choice for most older Lisle brick because it is softer than the brick and absorbs movement. Type S mortar is harder and used where structural loads call for it. The rule that protects your house: the mortar should be softer than the brick. Older brick is soft, so a too-hard mortar pushes the stress into the brick and it spalls. Matching the right mortar is exactly what a quality estimate accounts for.

What drives the cost of tuckpointing in Lisle

Every wall is different, so we never quote a flat per-foot rate sight unseen. What moves the estimate:

• Extent of failure — spot repointing versus a full elevation
• Height and access — ground-floor from ladders; upper walls and chimneys need scaffolding
• Mortar matching difficulty — a precise match on a visible front takes more care
• Brick condition — already-spalled brick is replaced as part of the work
• Chimney and detail work — chimneys and sills are slower than flat field walls

We explain each factor on-site, and the estimate is free. For the number on your home, call (708) 448-8866.
