Lintel Replacement for Commercial Buildings in Toronto & the GTA

Failing lintels threaten structural collapse, safety, and property value in commercial buildings. As a leading commercial masonry contractor in Toronto, A&A Masonry specializes in lintel replacement for commercial buildings across the GTA. Our WSIB-compliant, CSA-approved solutions prevent wall failure and emergency closures.

Why Lintel Replacement Is Critical

Lintels fail due to:

Rust Expansion

Rust expansion cracking surrounding brickwork.

Corrosion

Corrosion from water or de-icing salts.

Overloading

Overloading from signage or HVAC units.

Visible Sagging

Visible sagging or cracks above openings.

Collapse Risk

Unsupported masonry endangering lives.

Our structural brick repair in Toronto prevents wall collapse.

Common Lintel Failure Signs in Commercial Buildings

Toronto’s climate—freeze-thaw cycles, road salt, and roof runoff—accelerates lintel corrosion. Typical warning signs include:

Orange rust stains bleeding through joints.

Diagonal cracks indicating deflection.

Visible bowing over doors or windows.

Flaking masonry from rust expansion.

Interior leaks near window heads.

Left unchecked, these signs can escalate into emergency evacuations, code violations, and lawsuits. For heritage buildings, improper repairs without heritage masonry restoration in Toronto risk loss of designation.

Frequently Asked Questions on Lintel Replacement Commercial

What are the signs that a lintel needs replacement in a commercial building?

Cracked or displaced brick directly above windows/doors, sagging arches, rust stains (rust-jacking), horizontal cracking at the bearing ends, or visible corrosion on steel angles are all red flags. These are considered urgent structural issues by Toronto Building inspectors.

Can lintel replacement be done without removing the entire brick arch or wall above?

Yes—in almost every case. We install temporary hydraulic shoring or needle beams, cut out only the failed lintel, slide in a new galvanized or stainless-steel angle, and rebuild the bearing pockets. Zero masonry above is removed.

How long does commercial lintel replacement take in Toronto?

One lintel: 2–5 days. Full building with 10–20 lintels: 3–10 weeks (done sequentially). All work is scheduled after hours or weekends so entrances and storefronts stay open.

Do you need a permit for lintel replacement in a commercial building?

Yes—any structural steel replacement requires a City of Toronto building permit and P.Eng-stamped drawings. We handle the entire application, structural design, and inspections at no additional cost.

Is lintel replacement covered by commercial property insurance?

Almost always—failed lintels are classified as imminent collapse hazards. We supply engineer reports, photos, and detailed scopes that insurance companies accept for direct billing (we’ve successfully claimed hundreds of lintels).
