Brick Repair in Hinsdale, IL — On a Historic Home, What You Don't Do Matters Most

Brick Repair in Hinsdale, IL

Brick repair in Hinsdale, IL is unusual in one respect: on the village's older homes, the damage we are called to fix was often caused by the last repair, not by the weather. Paul Lally's Masonry Inc. repairs brick on historic, estate and modern homes throughout Hinsdale and DuPage County. Family-owned since 1988, insured, free on-site estimates. Call (708) 448-8866.

Which means a good part of the job is undoing well-intentioned work — carefully, so the original brick survives it.

Hinsdale Has a Lot of Old, Soft Brick

The village's building stock includes a substantial amount of genuinely old masonry — homes running back into the nineteenth century through the historic districts and the older residential streets, alongside grand early-twentieth-century houses and decades of later construction.

Brick from that older era is soft. It was fired at lower temperatures than modern brick, it is more porous, and it was laid in lime-rich mortar that was deliberately weak. That was not a limitation. It was the design: the mortar took the movement and the moisture, and it wore out first on purpose.

Modern practice can destroy that balance in a weekend, and it happens constantly.

The Three Repairs That Cause the Damage

1. Hard mortar

The rule is simple and absolute: mortar must be softer than the brick it sits against. When a century-old wall is repointed with a strong Portland-heavy mix, the relationship inverts. Movement, moisture and freeze pressure that the joint used to absorb now go into the brick faces, and the faces spall.

The tell: crisp grey joints standing slightly proud of crumbling brick. Once you have seen it you cannot unsee it, and it is on a lot of houses.

2. Cement patching

A grey cement patch over a spalled area is denser and far less permeable than the brick around it. Moisture moving out through the wall reaches the back of the patch, cannot pass, and freezes there — removing a bigger piece than the original damage, often with the patch still attached.

3. Sandblasting and aggressive pressure washing

This one is irreversible. Sandblasting strips the hard fired face off brick, exposing the soft, absorptive interior permanently. A wall that was durable becomes a sponge, and every winter afterward does damage that the original face would have shrugged off. Harsh pressure washing does a gentler version of the same thing.

On older masonry, the gentlest method that works is the correct method.

What Weather Damage Looks Like Instead

Genuine weather-driven failure has a different signature, and it concentrates:

• The bottom two or three courses, from splash-back off drives, walks and patios plus winter salt
• Under sills, where a whole window's runoff lands on one joint
• The weather elevation, generally north and west
• Chimneys, exposed on four sides with nothing over them
• Beside a downspout that has been discharging on the wall for years

If damage is scattered evenly across a whole elevation, look harder at the mortar and at what was done to the wall — not at the sky.

When Brick Gets Replaced Rather Than Repaired

• Spalled units — the fired face is gone and cannot be restored
• Units cracked all the way through
• Units that have lost bond — they move, or sound hollow when tapped
• Brick displaced out of plane from movement or corroding steel
• Badly impact-damaged units

And what does not need replacement: eroded mortar joints with sound brick faces, which need tuckpointing; or staining and efflorescence on otherwise intact brick.

Signs You Need Brick Repair

• Faces flaking, sheeting or crumbling
• Crisp mortar standing proud of receded brick faces
• Cement patches blistering, cracking or lifting away
• Cracked-through units, or brick you can move by hand
• Brick that sounds hollow when tapped
• A horizontal crack line with rust staining above an opening — corroding lintel steel
• Stepped diagonal cracking, which means movement rather than weather
• White efflorescence, proving water is moving through the wall

Risks of Waiting

A spalled brick has lost its hardest layer, so it takes on water faster than the sound brick beside it and each freeze-thaw cycle takes a little more — first from that unit, then its neighbours. On a historic home there is a second cost that does not apply elsewhere: every unit lost is original material that cannot be replaced in kind. The longer damage runs, the more of the house's actual fabric goes with it.

Our Process

1. Diagnose the cause — weather, a previous repair, corroding steel, or movement.
2. Assess the existing mortar hardness, because that changes the whole plan.
3. Sound the surrounding wall to find every unit that has genuinely failed.
4. Source the match, favouring salvaged and reclaimed period brick on older homes.
5. Remove failed cement patches and hard mortar by hand, with chisels rather than grinders where the brick is soft.
6. Cut out failed units without disturbing the courses above.
7. Correct what caused it — steel, drainage, a downspout, grade.
8. Set replacements in soft, matched mortar, keyed to the existing coursing and bond.
9. Blend, don't block — scatter new units through the surrounding field.
10. Repoint the transition, clean gently, and walk the finished wall with you.

Materials

Lime-rich, low-Portland mortars on the village's older masonry, matched for colour, sand and texture against cured mortar rather than the wet mix. Type N on modern brick. Salvaged brick wherever it serves the match better than new material.

Related services: brick replacement, tuckpointing, masonry restoration, limestone and sill repair, and lintel replacement.

What Drives the Cost

• How many units come out once the wall is properly sounded
• Match difficulty, and whether salvaged material must be sourced
• Undoing prior repairs — hard mortar and cement patches add real hand labour
• Height and access
• Whether the underlying cause has to be corrected
• Site conditions — landscaping, mature plantings, tight access
