Lintel Repair in Evergreen Park, IL — Rusted Steel Lintels Fixed Before the Brick Cracks

Quick answer

Emerald Masonry LLC repairs and replaces rusted, failing steel lintels on homes and buildings throughout Evergreen Park, IL. When the hidden steel lintel above a window, door, or garage opening rusts, it expands and lifts the brick above it — cracking the wall. We shore the opening, replace or treat the lintel, and rebuild the brick. Free on-site estimates — call (708) 288-1696.

What a lintel is — and why it fails

A lintel is the horizontal support that carries the weight of the brick above an opening such as a window, door, or garage. On most Evergreen Park homes that lintel is a steel angle hidden just behind the brick. Steel and Chicago weather are a bad long-term match: once the protective coating wears away, water and road-salt spray reach the bare metal and it begins to corrode.

Here's the part most homeowners don't realize: as steel rusts, it expands to roughly ten times its original thickness. That expansion has nowhere to go but up and out, so it pushes directly into the brick course resting on it. The result is lifted, cracked, and displaced brick over the opening — a problem known as rust jacking. The crack isn't the disease; the rusting lintel underneath is.

Signs you need lintel repair

On Evergreen Park bungalows, two-flats, and storefronts, look for:

• Orange-brown rust stains weeping down the brick just below a window, door, or garage header.
• Stair-step cracks climbing diagonally through the mortar joints above or beside the opening.
• A horizontal crack or gap right where the brick meets the top of the window or door frame.
• A sagging or bowed brick course directly over the opening.
• Brick that sounds hollow, has shifted forward, or shows a visible lip above the lintel line.
• Windows or garage doors that suddenly bind because the opening above them has moved.

If you can see daylight, gaps, or rust at the top corners of an opening, the lintel is already working against your wall.

The risk of waiting

A rusting lintel never improves on its own — it accelerates. Each freeze-thaw cycle drives more water to the steel, more rust expansion lifts more brick, and cracks that started hairline-thin open wide enough to let water deeper into the wall. Left alone, a single failed lintel can progress from cosmetic staining to loose, falling brick over a doorway or garage — a genuine safety hazard and a far larger rebuild. Catching it while only one brick course is affected is the difference between a one-day repair and a wall reconstruction.

Our lintel repair process

1. Free on-site assessment. We inspect every opening, confirm which lintels are failing, and check the brick above each for how much can be saved.
2. Shore the opening. We temporarily support the masonry above so the wall is stable while we work.
3. Remove the affected brick course. Only the brick resting on the lintel comes out — carefully, so existing units can be reset where sound.
4. Replace or treat the lintel. We install a correctly sized galvanized or coated steel lintel, or remediate and protect the existing steel where replacement isn't required.
5. Rebuild and repoint. We reset salvaged brick or blend in matching replacements, then repoint so the repair disappears into the surrounding wall.
6. Seal and detail. Proper flashing, end bearing, and joint work keep water away from the new steel so the fix lasts.

Materials we use

We install galvanized or shop-coated steel angle lintels sized to the opening and load, set on proper end bearings. Brickwork is rebuilt with mortar matched to your existing joints in color and profile, and we use compatible flashing and sealants so water is directed out of the wall rather than back onto the steel. Where a few face bricks must be replaced, we source the closest available match in size, color, and texture.

What drives the cost

Every Evergreen Park lintel job is priced from what we find on site. The biggest cost factors are the width of the opening, how many lintels are failing, whether the brick above can be reset or must be replaced, the access height (a garage header at grade is simpler than a second-story window), and the difficulty of matching older brick and mortar. We walk you through each factor during the estimate and never quote an exact number over the phone — masonry priced sight-unseen is a red flag.

Serving Evergreen Park

Evergreen Park's housing stock leans heavily toward solid brick bungalows, Georgians, and two-flats from the mid-20th century, plus a steady line of brick-front storefronts along 95th Street. That era relied on bare or lightly painted steel lintels, which is exactly why we see so much rust jacking here today. Combine that aging steel with Chicagoland's hard freeze-thaw winters and the road salt thrown off nearby arterials, and lintels in Evergreen Park corrode faster than in many milder climates. We know these homes and storefronts and repair them with details suited to local exposure.
