LintelRescue™ Garage Lintel Repair in Alabama & Tennessee — Fix Cracks Above Your Garage Door in 1 Day, Free Estimates

Request Your Free Estimate

Cracks above a garage door are one of the most commonly misdiagnosed problems in Alabama and Tennessee homes. Homeowners notice stair-step cracks in the brickwork, sagging above the door opening, or a gap forming between the brick and the door frame — and assume it is a foundation settlement problem. In many cases it is not. It is a failing garage door lintel. According to the Federal Emergency Management Agency, structural failures caused by undersized or deteriorated horizontal support members — including garage lintels — are among the most preventable forms of residential structural damage in the southeastern United States. The Crack Guys fix failing garage lintels across Alabama and Tennessee using our proprietary LintelRescue™ system — a permanent, engineered repair that stops further sagging, protects the brickwork above, and is completed in a single day. Every installation is backed by a lifetime transferable warranty and a free estimate.

What Is a Garage Door Lintel?

A lintel is the horizontal structural member that spans the top of your garage door opening and supports the weight of the brickwork, masonry, or wall structure above it. In a brick veneer home — which describes the majority of homes in Alabama and Tennessee — the garage door lintel is carrying the full weight of every course of brick above the opening, often 6 to 10 feet of brick extending to the roofline.

Lintels are typically made of steel angle iron, reinforced concrete, or in older homes, wood. Steel lintels are the most common — a steel angle iron is embedded in the mortar behind the face brick, with the brick sitting on the horizontal leg of the angle. When the lintel is properly sized and in good condition, it is invisible — it does the job silently and the brick above the door looks perfectly stable. When it fails, the results are hard to miss.

Why Garage Lintels Fail in Alabama and Tennessee

Lintel failure in our region comes down to two primary causes — and both are extremely common:

Undersized Lintel From Original Construction

Building codes historically did not require lintels to be sized for the full load they carry in brick veneer construction. A lintel that is technically code-compliant at the time of construction may still be undersized for the actual weight of brick above the opening — particularly for wide garage doors. Single-car garage openings are 8 to 9 feet wide. Double-car garage openings are 16 feet wide. The longer the span, the more load the lintel must carry, and the more critical proper sizing becomes. Most lintel failures in newer homes come down to an undersized lintel that was never strong enough to carry the load it was given.

Corrosion and Deterioration Over Time

Steel lintels are embedded in mortar — a damp environment that promotes rust over time, particularly in Alabama and Tennessee’s humid climate. As the steel corrodes, it expands — a process called rust jacking — which pushes the brick outward and causes the horizontal crack pattern seen just above the lintel. As the lintel loses cross-sectional strength to corrosion, it also loses its ability to carry the load above, leading to progressive sagging. Wood lintels in older homes are vulnerable to moisture damage and termite activity that produces the same result.

Warning Signs of Garage Lintel Failure

• Stair-step cracks in the brickwork above the garage door — running diagonally from the upper corners of the door opening upward and outward
• A horizontal crack in the mortar joint just above the lintel — indicating the lintel is pulling away from the brick above it
• Vertical cracks appearing in the center of the brick above the garage door — where the lintel is sagging at its weakest mid-span point
• Visible sagging or bowing in the middle of the brick course directly above the garage door — often described as a “smile” shape
• A gap forming between the brick and the garage door frame at the top of the opening
• Bricks that appear to be shifting outward from the wall plane above the door
• Cracks that return after being tuckpointed or filled — because patching the brick without addressing the lintel failure will never hold

The LintelRescue™ System — Our Proprietary Solution

The Crack Guys repair failing garage lintels using our proprietary LintelRescue™ system — an engineered permanent repair that addresses the root cause of lintel failure rather than just patching the visible symptoms.

How LintelRescue™ Works

The LintelRescue™ system installs specially engineered steel support members that take over the load-carrying function of the failing lintel — transferring the weight of the brick above the garage door to a new, properly sized structural system that is designed for the actual load it carries. The system is installed from the interior of the garage without requiring the removal of the brick above the door, without scaffolding, and without a multi-day disruption to your home. In most cases the installation is completed in a single day.

What LintelRescue™ Achieves

• Stops further sagging permanently — the new support system carries the load the failed lintel could no longer support
• Protects the brick above the door — once the lintel is properly supported, the pressure causing cracks is relieved and further brick movement stops
• Eliminates collapse risk — a failing lintel left unaddressed will continue to deteriorate until the brick above the opening becomes unstable. LintelRescue™ eliminates that risk permanently
• Completed in one day — no multi-week disruption, no scaffolding, no brick removal required in most cases
• Lifetime transferable warranty — every LintelRescue™ installation is backed by The Crack Guys’ lifetime warranty that transfers with the home at sale

Why Tuckpointing Alone Will Not Fix a Failing Lintel

Tuckpointing — filling cracks in the mortar joints with new mortar — is a common cosmetic repair for the visible cracks above a garage door. It makes the brick look repaired. But it does not address the lintel failure that caused the cracks. Within one to two seasons, the same cracks will reappear — often wider than before — because the lintel is still failing and the brick above it is still moving.

Filling cracks without repairing the lintel is the masonry equivalent of painting over a water stain without fixing the leak. The Crack Guys identify and repair the lintel failure first. The brick cracks can then be tuckpointed once the movement is permanently stopped — and those repairs will hold because the underlying cause has been eliminated.

Frequently Asked Questions — Garage Lintel Repair

How do I know if my cracks are from a lintel problem or a foundation problem?

The location and pattern of the cracks are the primary diagnostic clues. Stair-step cracks starting at the upper corners of the garage door opening, a horizontal crack just above the door in the first mortar joint, or a visible sag in the brick directly above the door — these are lintel failure patterns. Foundation settlement typically produces diagonal cracks at corners of doors and windows throughout the home, sloping floors, and sticking doors — not just isolated cracks at the garage opening. The Crack Guys will diagnose the specific cause during the free inspection and recommend the appropriate repair.

Can the brick cracks be repaired after the lintel is fixed?

Yes — and this is the correct sequence. Tuckpointing or repointing the brick cracks before the lintel is repaired will not hold because the movement causing the cracks has not been stopped. Once LintelRescue™ permanently stabilizes the lintel, the brick above the door stops moving and the cracks can be tuckpointed with confidence that the repair will last.

How long does LintelRescue™ installation take?

Most LintelRescue™ installations are completed in a single day. The system is installed from the interior of the garage in most cases — no scaffolding, no brick removal, and no multi-day disruption to your home or garage use.

Is a failing garage lintel dangerous?

Yes — a lintel that has progressed to the point of significant sagging and cracking creates a genuine collapse risk for the brick above the garage door opening. Bricks falling from a height of 8 to 16 feet can cause serious injury and significant property damage. If you are seeing visible sagging or the cracks above your garage door are widening, contact The Crack Guys for a free inspection as soon as possible.

My garage lintel was already tuckpointed and the cracks came back. What does that mean?

It means the lintel failure was not addressed — only the visible symptoms were patched. Tuckpointing fills the cracks in the mortar but does nothing to stop the lintel from continuing to sag and the brick from continuing to move. The cracks will continue to return, typically wider each time, until the lintel is properly repaired. LintelRescue™ stops the movement permanently so that tuckpointing will finally hold.

How much does garage lintel repair cost?

LintelRescue™ installation costs vary based on the width of the garage opening, the extent of brick movement, and site conditions. The Crack Guys provide free, no-obligation estimates — you know the exact cost before any work begins. GreenSky financing is available with monthly payments as low as $96 on qualifying projects.

Does the LintelRescue™ warranty transfer if I sell my home?

Yes. The Crack Guys’ lifetime warranty on LintelRescue™ installations transfers to the new owner at no cost — providing documented proof of a permanent professional repair that is covered for the life of the home. This is a meaningful selling feature that buyers and home inspectors in Alabama and Tennessee recognize.
