Masonry Restoration in Downers Grove, IL — Two Centuries of Brick on One Map

Downers Grove is unusual among DuPage County suburbs, and it makes masonry advice harder to give in general terms: the village has genuine 1830s-onward building stock and 1990s subdivision brick within a few miles of each other.

Those two walls want opposite treatment. Masonry restoration in Downers Grove, IL applies to the first kind — the century-old brick and stone around the older streets and the Metra corridor — and the single most damaging thing you can do to it is repair it the way you'd repair the second. Paul Lally's Masonry has been restoring Chicagoland masonry since 1988.

Restoration, or repair?

Restoration is the right frame when:

• The house is pre-1930s and has never had comprehensive masonry work
• Mortar is soft across whole elevations, not in patches
• Several components are failing at once — joints, brick, stone, chimney, lintels
• Previous work used the wrong mortar and is now damaging the brick
• Original brick and limestone are worth preserving rather than replacing

Repair is the right frame on later construction — including most of the village's post-war and subdivision housing, where the wall is brick veneer with a drainage cavity and the questions are about weep holes, flashing, ties, and control joints rather than lime mortar. See brick veneer vs. solid masonry.

The rule that governs a period home

Mortar must always be softer than the masonry beside it.

Mortar is the sacrificial element — deliberately weaker than the brick so thermal movement, moisture cycling, and settlement are absorbed by the joint, which is straightforward to replace. That's why hundred-year-old walls are still standing.

Pack a modern, Portland-rich mortar into that wall and the physics invert. The joint is now harder than the brick, so the brick face becomes what gets sacrificed and spalls along every mortar line.

A "stronger" repair destroys the building it was sold to protect, and it isn't reversible. Repointing can be redone. Brick faces and carved stone cannot be put back. On Downers Grove's older homes this is the most common thing we're called in to correct — usually the work of a contractor who reached for the strongest bag on the shelf because the house was old and it seemed prudent.

What restoration covers

• Repointing with matched mortar — joints cut to depth and repacked with a mix suited to the original masonry
• Brick repair and replacement — spalled and cracked units, matched or salvaged
• Limestone and stone restoration — sills, lintels, water table, steps, porch piers, trim
• Chimney repair and rebuilds above the roofline
• Lintel repair and replacement where steel has rusted, or stone lintels have cracked
• Gentle cleaning — never sandblasting, never aggressive pressure
• Caulking and joint sealant at movement joints and window perimeters
• Waterproofing — breathable penetrating sealers only, last, and only where warranted

Signs a Downers Grove home is ready

• Mortar you can rake out by hand across whole elevations
• Spalling brick — faces flaking, powdering, popped off
• Spalling concentrated at joint edges — the signature of hard mortar against soft brick
• Delaminating limestone — stone coming away in flat sheets
• Eroded sills with the drip edge worn away
• Deteriorated stone steps, stoops, and water table at grade, where de-icing salt works hardest
• A cracked chimney crown, missing cap, or soft joints above the roofline
• A horizontal crack above a window with rust staining — a corroding lintel
• Step cracks climbing through the joints
• Efflorescence and damp interior walls
• Previous repointing that looks grey and hard against softer brick

How we restore a period home

1. Read the building first. Its era, its brick, its mortar, its stone. This determines the whole approach and comes before any scope discussion.
2. Test the mortar and brick hardness so the replacement mix is genuinely softer than the masonry.
3. Walk the whole envelope — all elevations, chimney, stone, and the base course at grade.
4. Diagnose the water. Nearly every failure traces back to water reaching somewhere it shouldn't.
5. Sequence the work — cause before symptom, top of the house before the bottom, structure before surface, sealing last.
6. Cut joints to depth — roughly two to two and a half times the joint width. On very soft brick, joints are hand-raked rather than power-ground to protect the arrises.
7. Repoint with matched mortar — lime-rich or low-Portland, matched for color, sand, and joint profile, packed in layers and tooled to the existing profile.
8. Save original material. Brick removed during the work is cleaned and relaid. Stone gets patched or Dutchman-repaired rather than replaced.
9. Clean gently, if at all.
10. Walk the finished house with you, with a maintenance cadence.

Materials

Lime-based and low-Portland mortars for historic work, matched for color, sand grain, and joint profile. Type N where the masonry is later and harder; Type S only where structure and exposure genuinely warrant it. Salvaged brick where matching matters. Matched Indiana and Illinois limestone and tinted stone repair mortars. Breathable penetrating sealers only.

What we don't use on a century-old Downers Grove home: hard modern high-strength mortar, sandblasting, high-pressure washing, film-forming sealers, or masonry paint.

What drives the cost

• Number of elevations and whether the work is phased
• Height and access — staging on a large period home is a real portion of the job
• Ratio of repointing to brick and stone replacement
• Stone scope — patching, Dutchman repairs, or replacement, plus fabrication lead time
• Chimney condition — repoint, crown work, or an above-roofline rebuild
• Matching difficulty and salvage sourcing
• How much previous bad work has to be undone — a genuine cost driver on homes repointed with hard mortar
• Hand-work requirements where the brick is too soft to power-grind
• What's found once the joints are open

Local context: reading a Downers Grove address

The village was settled in the 1830s and grew as a rail suburb, which produced an unusually layered housing stock — and the era tells you almost everything about the correct approach.

The older streets near downtown and the Metra corridor hold Victorians, Queen Annes, four-squares, bungalows, and Prairie-influenced homes. Soft, lower-fired brick, lime-based mortar, and limestone used generously: sills and lintels at every opening, a water table near grade, stone steps and stoops, porch piers. This is restoration work, and it wants soft mortar, gentle cleaning, and stone saved rather than swapped.

The mid-century stock — post-war ranches, split-levels, and Georgians — sits in between. Harder brick, often veneer, and generally Type N territory.

The 1970s-onward subdivisions are brick veneer over frame with a drainage cavity, flashing, and weep holes. That's repair, not restoration, and the diagnosis is different.

Across all of it, DuPage County weather: repeated hard freeze-thaw cycling, wet springs, and wind-driven rain from the west and northwest that pushes water horizontally into joints. The failures cluster on north and west elevations, at the front edge of sills where drip edges erode, at chimney shoulders, and at grade, where de-icing salt on walks and drives draws into porous stone and crystallizes as it dries.
