Elmhurst has a deeper stock of genuinely old buildings than people expect from a DuPage suburb. The city dates to the 1840s and grew along the rail line through the late 19th and early 20th centuries, leaving neighborhoods of Victorians, Queen Annes, Foursquares, Tudors, Colonial Revivals and Prairie-influenced homes alongside the 1920s brick housing that fills much of the older grid, plus the churches, school buildings and downtown commercial masonry around York and Schiller.

Most of that masonry is on original joints, and mortar does not last a hundred and twenty years.

The Problem We Get Called About Most Here

Not deterioration — previous repairs.

Elmhurst's older housing is desirable and well-maintained, which means a lot of it has been worked on. And a substantial share of that work was done with modern Portland-based mortar on brick that cannot take it.

Here is why that matters. A masonry wall is designed so the mortar is softer than the brick. Mortar is the sacrificial layer — it absorbs movement and moisture stress and wears out first, because mortar is cheap to replace and hundred-year-old brick is not.

Point a soft pre-1930 wall with hard modern mortar and the relationship inverts. The joints become the strongest element, and every freeze-thaw cycle drives stress into the brick faces instead. Three to eight winters later the faces begin popping off — permanent loss of original material, caused by the repair.

| | Historic wall (pre-1930) | Modern wall (post-war) | |---|---|---| | Mortar | Lime-rich, soft, breathable | Portland-based, hard, dense | | Brick | Softer, variable, often locally made | Machine-made, dense, uniform | | Joint prep | Hand-raked, shallow tools | Power grinding acceptable | | If mismatched | Brick faces spall and are lost | Mortar erodes early | | Cleaning | Gentle only — never blasting | Wider tolerance | | Sealing | Breathable products only | Wider range |

If your brick started flaking a few years after somebody repointed it, that is not coincidence.

Signs an Elmhurst Historic Home Needs Restoration

• Mortar joints receded well behind the brick face, or raking out as loose sand.
• Spalling brick — faces flaking, popping or delaminating, worst below sills and near grade.
• Hard gray mortar standing proud of softer, warmer-toned original brick — a prior bad repair.
• A band of spalling corresponding exactly to where repointing was done.
• Cracked, eroded or displaced stone sills, lintels and water tables.
• Open joints and deteriorated crowns on original chimneys — tall and heavily exposed on these houses.
• Efflorescence blooming on interior or exterior masonry.
• Step cracks through joints at corners and around openings.
• Evidence of past sandblasting — an unnaturally rough, open brick surface that now absorbs water freely.

Our Restoration Process

1. Assessment and documentation. We walk the building, photograph conditions, evaluate the existing mortar's hardness and composition, and flag prior inappropriate repairs.
2. Mortar analysis and matching. A mix formulated to the original — soft enough to protect the masonry, durable enough to serve.
3. Hand joint preparation. Joints raked by hand where the brick is soft; power tools only where masonry can safely take them. Aggressive grinding permanently widens joints and chews the brick arrises.
4. Undoing bad repairs where hard mortar has to come out, carefully, without taking more brick with it.
5. Repointing in lifts, packed and compacted, then tooled to the original joint profile at the right firmness.
6. Brick and stone repair. Failed units replaced with salvaged or reproduction matches; stone restored with dutchman inserts or matched patching rather than wholesale replacement.
7. Chimneys and trim restored to shed water properly.
8. Gentle cleaning, breathable protection. No sandblasting, no high-pressure washing, no film-forming sealers.

Materials We Use

Lime-based and lime-modified mortars custom-blended to the original, matched sands for true color, salvaged and reproduction brick, Indiana limestone and matched patching compounds for stone, and vapor-permeable sealers only. Related work commonly includes tuckpointing, limestone and sill repair, chimney repair and brick replacement.

What Drives Restoration Cost in Elmhurst

• Scope — one elevation, a full facade, or the whole envelope including chimneys.
• Mortar matching complexity — a custom historic blend is more work than a bagged mix.
• Hand work — soft brick means hand-raking, slower by design.
• Undoing prior hard-mortar repairs — often the single largest variable on an Elmhurst job.
• Access and staging — tall Victorians and steep roofs need real setups.
• Sourcing — salvaged period brick and matched stone are not always immediately available.
• Review and permitting where a designation applies.

Working in Elmhurst and Across DuPage

DuPage County has no lake moderation, so freeze-thaw cycling here is aggressive — dozens of crossings of the freezing point each winter, each a load cycle on saturated masonry. Elmhurst's mature tree canopy shades north elevations and keeps them damp long after a storm, which is why the same house often has sound masonry on one side and failing masonry on another. Heavy clay soils move seasonally and show up as step cracks at the corners of older buildings.

We work throughout 60126 — the older residential streets around Wilder Park and the Elmhurst Art Museum, the century homes near the Metra line and York Street, the neighborhoods around Elmhurst University, the churches and school buildings, and the brick commercial stock downtown. We also serve neighboring Villa Park, Lombard, Oak Brook and Hinsdale. Elmhurst owners often pair restoration with tuckpointing or chimney repair.

Why Deferring Costs More on an Old Building

On a century-old wall, waiting is not just a bigger repointing bill later — it is the permanent loss of original material. Once the face spalls off a hundred-year-old brick, that brick is gone, and every replacement is a compromise against the original. Restoration is always cheaper, and always more authentic, when it happens before the units themselves start failing.
