Restoring a century-old Flossmoor home is not the same job as repairing a modern wall. The single most important rule: the repair must be softer than the brick, or it does more harm than good.

Why Historic Masonry Needs a Different Approach

Homes built in Flossmoor in the early decades of the 1900s were laid with soft, low-fired brick and lime-rich mortar. That system was designed to move and breathe — the mortar, weaker than the brick, absorbed building movement and freeze-thaw stress and could be renewed without harming the brick. Repair that wall with modern high-Portland mortar, which is harder than the original brick, and every winter the trapped stress and moisture have nowhere to go but the brick faces, which spall and crumble. Hard mortar on soft historic brick is the most common and most destructive masonry mistake there is. Historic restoration exists to avoid exactly that.

Signs Your Flossmoor Home Needs Restoration

• Eroded, sandy, or missing mortar joints, often with the original lime mortar washing out.
• Spalling or flaking brick — frequently a sign the wall was previously repointed with mortar that was too hard.
• Cracked, eroded, or displaced limestone sills, lintels, copings, and decorative trim.
• Open joints around stone surrounds, water tables, and chimneys.
• Past repairs that look wrong — gray modern mortar smeared over a warm historic wall, or mismatched brick patches.
• Water staining, efflorescence, or damp interior walls tracing back to open joints.

Our Restoration Approach

1. Survey the building. We document the brick, the mortar, the stone, the joint profiles, and any prior repairs — and identify what is original and worth preserving.
2. Match the mortar. We mix repointing mortar to the original color, sand, texture, and strength — soft enough to protect the historic brick.
3. Repoint by hand. We carefully rake out failed mortar without damaging fragile brick arrises and repoint to the original joint profile.
4. Repair stone in kind. We patch, piece in, or carefully replace limestone and cut-stone trim to match the original profiles.
5. Clean gently. Low-pressure, appropriate methods only — never sandblasting or high-pressure washing.
6. Preserve, not replace. We keep original material wherever it can be saved; replacement is the last resort, matched closely when unavoidable.

Materials — Matching the Original System

Good historic restoration is a matching exercise on three fronts. Mortar: matched in color, aggregate, profile, and softness so it protects rather than punishes the brick. Brick: salvaged or closely matched units when replacement is truly necessary, set to read as original. Stone: limestone and cut-stone trim repaired with compatible patching materials or pieced in with matching stone. Get any one of these wrong and the restoration announces itself; get all three right and it disappears into the building.

What Affects the Price

• Extent and access — isolated joints and one stone sill versus full elevations and high, ornate work needing staging.
• Match difficulty — a straightforward lime mortar match versus tinted, custom-profile work and sourced salvage brick or stone.
• Stone repair — sealing a joint versus carving, piecing, or replacing decorative limestone.
• Undoing past mistakes — removing inappropriate hard mortar or failed prior repairs adds scope.

Historic work can only be priced by examining the building — and Emerald Masonry provides that on-site assessment free across Flossmoor.

Local to Flossmoor and the South Suburbs

Flossmoor grew as a leafy commuter village around its Illinois Central station, and it shows in the housing: tree-lined streets of 1920s and '30s Tudors, Georgians, Colonials, and custom brick-and-stone estates, many in and around the local historic district. That stock is now a century into its life — original lime mortar washed thin, limestone trim weathered, and in too many cases marred by well-meaning but damaging hard-mortar repairs. These are the homes historic restoration exists for, and exactly the work we are called out to do across the south suburbs. We treat an older Flossmoor home as something to conserve, not just patch.

Frequently Asked Questions

How is historic masonry restoration different from regular tuckpointing in Flossmoor?

Older Flossmoor homes were built with soft brick and lime-based mortar, and they have to be repaired in kind. Standard hard Portland-cement mortar is stronger than the original brick, so over freeze-thaw cycles it forces the damage into the brick faces. Historic restoration means matching the original mortar's softness and color, using gentle cleaning, and preserving original material rather than replacing it.

Can you match the mortar and stone on a 1920s Flossmoor home?

Yes — matching is the core of the work. We match repointing mortar to the original color, texture, joint profile, and crucially its strength, and we match or repair limestone and cut-stone trim rather than swapping it for something that looks wrong. The goal is a restoration that reads as original, not as a patch.

Do you do gentle cleaning, or will you sandblast the brick?

We never sandblast or high-pressure power-wash historic brick — both strip the protective fired surface and accelerate decay. Historic masonry is cleaned with the gentlest effective method: low-pressure, appropriate cleaners, and patience. Preserving the original surface is the whole point.
