Brick lintels protect one of the most important areas of your home: the masonry above windows and doors. When a lintel rusts, bends, or moves, the bricks above it can crack and shift. Water can also enter around the opening.
At Casey Tuckpointing, we repair brick lintels, beams, and channels throughout Chicago and nearby suburbs. Our family-owned business has served the area since 1994. We use careful masonry methods, quality materials, and clear advice. We do not push work you do not need.
What Is a Brick Lintel?
A brick lintel is a steel support placed above a window or door. It carries the weight of the bricks above the opening. Many Chicago homes and older buildings have steel lintels hidden behind brick or stone.
Over time, moisture can reach the steel. The steel then begins to rust and expand. This pressure can crack the mortar and push the bricks outward. Some lintels also sag because of age, poor drainage, or movement in the wall.
Lintel damage may look small at first. A few cracks or a rust stain can point to a larger problem. A masonry professional should inspect the area before you patch or paint it.
Our Chicago masonry services cover lintel work, tuckpointing, brick repair, chimney repair, parapet walls, and building restoration.
Signs Your Brick Lintel Needs Repair
Look closely at the brickwork above each window and door. Pay attention to changes after heavy rain or a Chicago winter. Common warning signs include:
- Cracks that run diagonally from the top corners of a window or door
- Bricks that bow, bulge, or move outward
- Rust stains below or beside the opening
- Flaking brick faces, also called spalling
- Mortar that crumbles when you touch it
- A lintel that sags in the center
- Gaps between the window frame and the brick
- Water stains or damp spots inside near the opening
- Windows or doors that become hard to open
These signs do not always mean you need a full lintel replacement. Sometimes the steel remains sound and only the surrounding mortar or brick needs repair. We inspect the whole area before we recommend a solution.
Why Chicago Weather Damages Lintels
Chicago’s freeze-thaw cycles create special problems for brick buildings. Water enters small cracks and weak mortar joints. When temperatures drop, that water freezes and expands. When temperatures rise, the ice melts. This cycle repeats and places stress on the wall.
Rust creates another problem. As steel corrodes, it expands inside the masonry. The pressure can break mortar joints and damage nearby bricks. Water infiltration through deteriorated mortar joints is one of the leading causes of structural damage in brick buildings, according to the Brick Industry Association.
Good drainage matters, too. Damaged coping, flashing, caulking, or window seals can send water toward the lintel. A lasting repair must address the source of the water when possible. Otherwise, the same damage may return.
Brick Lintel Repair vs. Replacement
The right repair depends on the condition of the steel, bricks, mortar, and wall around the opening. We may recommend one of these options:
Mortar and Brick Repair
If the lintel still provides proper support, we may remove loose mortar and damaged bricks. We then install new mortar and replace bricks that cannot be saved. We match the color, size, and texture as closely as possible.
This work can restore the appearance of the wall and keep water out. It may also solve minor movement before the damage spreads.
Lintel Cleaning and Coating
A sound steel lintel may need cleaning and a protective coating. We remove loose rust and prepare the metal before sealing it. We also repair the surrounding masonry and close open joints.
This option only makes sense when the lintel remains strong. A coating cannot fix steel that has lost its shape or strength.
Brick Lintel Replacement
A badly rusted, bent, or sagging lintel may need replacement. This process usually involves supporting the masonry above the opening, removing enough brick to reach the steel, taking out the old lintel, and installing a new support.
We then rebuild the brickwork and finish the mortar joints. The work requires care because the wall above the opening carries weight. It also requires safe access and the right support during the repair.
For related masonry concerns, read our guide to how to tuck point mortar joints. Tuckpointing can help protect sound masonry, but it cannot replace a failing lintel.
What Does Brick Lintel Repair Cost?
The price depends on the number of lintels, access, brick damage, wall movement, and the need for replacement. A small repair costs less than work on a multi-story building or a full row of windows.
For reference, Angi reports a typical cost of $300–$700 per lintel for lintel replacement. HomeGuide reports $700–$2,000 for minor to moderate brick repair. These figures provide a general guide, not a quote for your property.
The final price may include:
- Temporary support for the masonry
- Removal of damaged bricks and mortar
- Steel lintel removal and replacement
- Brick matching and rebuilding
- Mortar matching and tuckpointing
- Scaffolding or lift access
- Waterproofing, caulking, or flashing work
- Permit or documentation needs
We provide a clear assessment before work begins. You can request a free estimate so we can review the condition of your lintel and explain your options.
How Our Brick Lintel Repair Process Works
We keep the process direct and organized. Our typical steps include:
1. Property Assessment
We inspect the lintel, brick courses, mortar joints, window or door frame, and nearby drainage details. We look for rust, movement, cracks, water entry, and signs of past repairs.
We also ask about leaks, drafts, sticking windows, and changes you have noticed. These details help us understand how the damage developed.
2. Repair Plan and Estimate
We explain what we found in plain language. If the lintel only needs cleaning and masonry repair, we say so. If replacement makes more sense, we explain why.
Our estimate outlines the planned work. We do not use scare tactics or add work without your approval.
3. Safe Masonry Support
When the repair requires lintel replacement, we support the masonry above the opening before removing the old steel. Proper support protects the wall, workers, and property.
The exact method depends on the size and height of the opening. Multi-story buildings may need scaffolding or other access equipment.
4. Lintel and Brick Work
We remove damaged materials with care. We install the new lintel when needed, rebuild the affected brickwork, and fill open mortar joints. Our European masonry background guides our attention to line, color, and finish.
We also check nearby areas. A lintel problem may connect to damaged brick, weak mortar, or water entry elsewhere on the facade.
5. Final Review
We inspect the finished area and clean the work zone. We review the repair with you and explain any follow-up care. If you manage a building, we can discuss documentation and permit needs as part of the project.
Other Problems That May Appear Near a Lintel
Lintel damage rarely exists in isolation. Nearby masonry may also need attention. A professional inspection can identify related concerns before they become separate repair projects.
Damaged Bricks
Cracked or spalled bricks may allow water into the wall. Our brick repair and masonry contractor guide explains why proper brick repair matters. We replace bricks that have lost their protective face or no longer support the wall properly.
Weak Mortar Joints
Old mortar can wash out or crumble. Tuckpointing removes the weak joint material and installs new mortar. The new mortar must work with the existing brick. Mortar that is too hard can damage older bricks.
Water Around Windows
Open caulk joints, failed flashing, and damaged sills can direct water toward the lintel. We may recommend waterproofing or sealing after masonry repairs. The goal is to keep water away from the wall, not just hide the stain.
Parapet and Facade Damage
On commercial buildings, water may travel from a parapet or upper facade down to a lintel. Casey Tuckpointing also handles facade rehabilitation in Chicago. We work with homeowners, landlords, property managers, architects, and condominium associations.
Should You Repair a Brick Lintel Yourself?
Small mortar repairs may look simple, but lintel work carries real risks. The masonry above a window or door can be heavy. Removing the wrong material without support can cause bricks to shift or fall.
It is also easy to use the wrong mortar or cover a structural problem with a quick patch. That repair may fail after another season of Chicago weather.
A licensed and fully insured masonry contractor can inspect the support, use safe methods, and identify related damage. Casey Tuckpointing does not subcontract our work. We handle projects with personal accountability from the first assessment through the final review.
