Historic Brick Restoration
Historic Brick Restoration For Buildings That Predate Modern Mortar
“Historic” isn’t a style — it’s a construction method. Buildings put up before modern masonry cement took over were laid with soft, breathable lime mortar and brick fired at lower, uneven temperatures. Repair them with today’s materials and today’s habits, and you don’t preserve them — you quietly take them apart, one freeze-thaw season at a time. Historic brick restoration means working the way the original masons did, with mortars they would recognize.
But “the way it was built” changed decade by decade. A workers cottage from the 1870s, a greystone from 1905, and a bungalow from 1928 carry three noticeably different mortars — so before we specify a mix, we place your building on Chicago’s construction timeline. The date on your deed narrows the recipe; a sample of your original mortar confirms it.
1871 – 1890
Workers cottages in Pilsen, Bridgeport, and McKinley Park — the city's oldest brick, laid in pure lime putty and sand. The softest walls we touch, and the least forgiving of shortcuts.
1890 – 1915
Indiana limestone veneers over common brick backing. Two materials aging at two speeds — restoration here means two different mortars on one building.
1900 – 1930
Pressed face brick fronts, common brick everywhere else, and lime-Portland blends that got gradually harder — each decade carries a slightly different recipe.
1910 – 1945
Denser autumn-blend face brick with tinted, raked joints that were part of the design. Matching the look matters here as much as matching the strength.
What Our Historic Brick Restoration Actually Covers
Reclaimed Brick Matching & Replacement
When a brick has spalled past saving, we source salvaged Chicago common brick and vintage face brick to match your wall's size, color range, and texture — because a 2020s brick set into a 1910s wall never stops announcing itself. Each replacement is laid in the same lime mortar as the joints around it.
Parapet, Chimney & Wall Rebuilds
Parapets and chimneys take weather from every side, so they fail first. Where repointing is no longer enough, we take them down course by course, save every reusable brick, and rebuild in period-correct mortar — with flashing and copings detailed so water finally sheds the way it should.
Gentle Cleaning & Paint Removal
A century of soot, paint layers, and graffiti comes off with the mildest method that works — low-pressure washing and masonry-safe chemistry, tested on a small patch first. Never sandblasting: it strips the fired skin off historic brick and turns a cleaning job into permanent damage.
Landmark-Ready Documentation
For buildings in Chicago's landmark districts, we prepare what the review actually asks for: existing-condition photos, a written mortar analysis, and a repair specification based on the Secretary of the Interior's Standards. Your permit package tells the Commission exactly how the wall will be treated — and why it's correct.
