Hinsdale has some of the oldest and best-built brick housing in DuPage County — Georgian and Tudor revival homes from the 1910s through the 1930s, early twentieth-century foursquares near downtown, and solid mid-century brick houses on the streets around them. Much of it was laid with lime-based mortar and brick fired softer than anything made today.

That makes tuckpointing in Hinsdale a different job from tuckpointing a 1990s subdivision home. The most important decision is not the colour of the mortar. It is how hard it is.

On an older Hinsdale brick home, the mortar is supposed to be the weakest part of the wall. Repoint it with something harder than the brick, and the brick becomes the part that fails.

What tuckpointing is

Tuckpointing — often used interchangeably with repointing — is the removal of worn mortar from the joints between bricks to a consistent depth, and its replacement with new mortar, packed in layers and tooled to the right profile.

Mortar joints are designed to wear out. They absorb movement, let moisture out of the wall, and weather away over decades so the brick does not have to. When they recede far enough, water gets in, freeze-thaw cycles go to work, and the wall starts to deteriorate from the inside.

Why the mortar must be softer than the brick

Older Hinsdale homes were built as breathing walls. Moisture moves in and out through the soft lime mortar joints. When a wall like that is repointed with modern, high-Portland mortar — Type S, or a bagged mix chosen for convenience — the joints become harder and less permeable than the brick around them.

The result is predictable:

• Moisture is trapped behind the brick faces instead of leaving through the joints.
• Thermal and seasonal movement concentrates at the brick edges.
• Freeze-thaw cycles pop the faces off, a failure called spalling.

We see the aftermath of this on DuPage County homes every year — sound mortar, ruined brick. On a historic house, those bricks are often impossible to replace with a true match.

That is why our default on pre-war Hinsdale brick is a lime-rich mortar, or at most a soft Type N or Type O blend, selected after looking at the brick and the existing joints.

Signs your Hinsdale home needs tuckpointing

• Mortar joints receded a quarter inch or more behind the brick face
• Sandy, crumbling mortar that rubs out with a fingertip or key
• Gaps or open joints, especially on chimneys and under window sills
• Efflorescence — white salt deposits — on brick faces
• Interior damp or plaster damage on exterior walls
• Earlier patching in grey, smeared mortar that does not match the rest of the house
• Brick faces spalling next to older hard-mortar repairs

The risks of waiting

Open joints let water into the wall. In a Chicagoland winter that water freezes and expands, widening the joint and attacking the brick edges. Each year the repair gets deeper: joints that could have been repointed become loose bricks, and loose bricks become sections of wall that have to be relaid. On a chimney, it can mean a partial rebuild.

Our tuckpointing process in Hinsdale

1. Assess the wall. We check brick hardness, existing mortar, joint width and profile, and any past repairs.
2. Match the mortar. Binder, sand and pigment are selected to match the original, and a test panel is made and left to cure so you approve the colour dry, not wet.
3. Remove old mortar. Joints are cut to a depth of roughly two and a half times their width. On soft brick and narrow joints we rake by hand or use controlled tools — an aggressive grinder chips brick edges and widens joints permanently.
4. Clean and dampen. Joints are brushed out and pre-wetted so the new mortar is not starved of water.
5. Pack in lifts. Deep joints are filled in layers, each firmed before the next.
6. Tool the profile. We match the original joint — concave, flush, struck or raked — because the profile changes how the wall looks as much as the colour.
7. Cure and clean. Mortar is protected while it cures and the wall is cleaned gently, without acid or high-pressure washing.

Materials used

• Lime-rich mortar or soft Type N / Type O blends matched to brick hardness
• Washed sand graded to match the original texture
• Mineral pigments for colour matching
• Salvaged or closely matched brick for any units replaced
• Breathable treatments only where they genuinely help — never a film-forming sealer on historic brick

Typical price factors

• Square footage of wall and how much is repointed versus spot-pointed
• Joint depth, width and condition
• Hand raking versus mechanical removal
• Height, roof access and scaffolding — chimneys and gables cost more to reach
• Difficulty of the colour and profile match
• Associated brick, chimney or limestone sill repairs

Tuckpointing Hinsdale's older brick — local context

Hinsdale homes are often large, two and a half storeys, with steep roofs, tall chimneys and decorative brickwork around entries. Mature trees keep north and east walls damp and shaded, and those elevations usually deteriorate first. Many houses have had at least one round of patching, and part of the job is undoing hard-mortar repairs from decades past.

If your home sits in a historic district or carries a landmark designation, check with the Village of Hinsdale before work begins. We provide mortar samples, a test panel and a written scope for any review.

The same pre-war brick housing runs into neighbouring Western Springs and Clarendon Hills, and we apply the same soft-mortar approach there.
