A technical white paper from Champion Brick Repair / LintelLOCK — Dallas–Fort Worth
When a brick lintel over a garage door starts to fail, the market offers roughly two kinds of solutions. Understanding the difference before you sign a contract will save you from paying twice — because we regularly get called to fix repairs that were “finished” two years ago.
Philosophy 1: Add steel to the face of the wall. Bolt a new angle iron under the old one, strap plates across the brick, or screw on brackets. It’s fast, it’s cheap, and it’s visible from the street.
Philosophy 2: Correct the structure inside the wall. Engineer a load path that carries the veneer properly, arrest the corrosion, manage water and thermal movement, and leave the face of the brick untouched.
Everything below is about why Philosophy 1 keeps failing — and what Philosophy 2 requires in practice.
Surface-mounted steel fails for the same reason the original lintel failed, only faster:
It’s unprotected by design. Steel buried in a wall at least had mortar around it. Steel bolted to the face of the brick is fully exposed to rain, humidity, and Texas sun. Rust starts immediately.
It creates new water paths. Every bolt driven through brick to mount a plate is a hole through the veneer — a direct channel for water into the wall cavity. The “repair” introduces the exact moisture problem that accelerates masonry failure.
It changes the structure cosmetically but not structurally. A plate screwed across the face of sagging brick doesn’t carry the veneer above the opening — the load path still runs through the failed original lintel. The bracket is decoration holding up nothing.
It tanks curb appeal. A black steel strap bolted across the front of a $400,000 home reads as damage, not repair. Appraisers notice. Buyers notice. Home inspectors definitely notice — and they flag it, because exposed retrofit steel with no engineering behind it is a red flag in a report.
We’ve removed more bolt-on “repairs” than we can count. In every case, the homeowner paid for the bracket job, lived with the eyesore, watched the sag continue underneath it, and then paid again for the real correction.
The word gets thrown around. Here’s the checklist that separates an engineered lintel system from a handyman special:
1. Load calculation. The system must account for the actual dead load of the masonry above the opening — brick is roughly 120 pounds per cubic foot, and a two-story gable over a 16-foot garage door is a serious number. “Looks strong enough” is not engineering.
2. Bearing design. The ends of any spanning element need adequate bearing on sound masonry — not on deteriorated piers, not on mortar alone. Bearing failure is Stage 3 of lintel collapse, and a system that ignores it just moves the failure point six inches sideways.
3. Corrosion strategy. Every steel component must be galvanized or otherwise protected, and the system must address the existing corroded steel — either removing it, isolating it, or bypassing its load path so ongoing corrosion can’t re-jack the wall.
4. Water management. Masonry walls get wet; that’s normal. What’s not normal is water with nowhere to go. Proper lintel work includes flashing above the steel and weep paths so moisture drains out instead of sitting on the steel and accelerating rust.
5. Thermal accommodation. A 16-foot steel span in DFW sees enormous temperature swings. Steel expands roughly 6.5 millionths of an inch per inch per °F — over 16 feet and a 100°F swing, that’s over an eighth of an inch of movement. The system must let the steel move without pumping the mortar joints apart. Rigid connections to the veneer guarantee cracked joints within a few seasons.
6. Concealment. All of the above happens inside the wall. The finished opening shows brick, mortar, and clean lines — the way the builder drew it. No brackets. No plates. No straps. No bolts on the face.
A bolt-on bracket job is cheaper on the invoice. It’s also the most expensive option over a ten-year horizon, because the failure continues underneath it and the eventual real repair costs the same as it would have on day one — plus the cost of removing the brackets and repairing the bolt holes.
An engineered internal correction costs more upfront and exactly once. When we say a LintelLOCK correction is backed for life, that’s the arithmetic behind it: the load path is permanent, the steel is protected, the water has somewhere to go, and there’s nothing on the face of the brick to rust, streak, or embarrass you at resale.
“Show me the load path.” A real contractor can sketch where the weight goes. A handyman changes the subject.
“What steel are you using, and how is it protected?” Galvanized or stainless. “Painted” is not protection in a masonry wall.
“Where does the water drain?” No flashing and weeps, no contract.
“Will there be any visible steel when you’re done?” The answer should be no.
“What exactly does your warranty cover, and for how long?” Get the paper, read the exclusions.
