garage doors
Lintels are the horizontal supports that are commonly made out of steel, stone, or concrete, and used to bear the load above openings. Over time, moisture, rust, or shifting masonry can compromise their strength. We provide structural repair and replacement services for damaged or sagging lintels above windows, garage doors, and fireplaces.

Sagging Garage Lintel Repair Cost

The cost of garage door lintel repair depends on the size of the opening and the severity of the damage.

Minor repairs (surface rust treatment, repointing mortar, lintel flashing installation): $400–$800

Partial reinforcement or steel plate support: $800–$2,000

Full lintel replacement above a garage door: $1,000–$4,000

Window Lintel Repair

A window lintel repair typically involves removing rusted sections, cleaning and coating exposed steel, and restoring the surrounding masonry. Costs usually range between $400–$1,000 per window lintel, depending on size and accessibility. For advanced deterioration, full lintel replacement may be necessary.

Garage Door Lintel Repair

A lintel above a garage door often supports a wide span. When sagging occurs, it may lead to cracks in brickwork or difficulty opening the garage. Repairs may involve steel reinforcement or complete replacement. Addressing issues early helps prevent larger structural damage.

Lintel Flashing

Installing or replacing lintel flashing is critical for preventing water infiltration and rust. Flashing redirects water away from the steel and mortar, extending the lifespan of the lintel and reducing the need for future repairs.

Rusted Lintel Issues

A rusted lintel expands as corrosion progresses, causing masonry cracks and bulges. Treatment involves removing loose rust, applying protective coatings, and repairing surrounding brick or stone. Severely deteriorated lintels may require replacement with new steel lintels.

Fireplace Lintel

A fireplace lintel supports the masonry above the firebox opening. Cracks, heat damage, or structural shifts may weaken the lintel. Repairs range from $400–$1,000, while full replacement may cost more depending on material (stone, brick, or steel).
