Garage Door Lintel Repair

Don Kennedy Holding Lintellift Patent
Don Kennedy and Sons Structural Solutions now holds the only patent in America for structural garage lintel repair!

Garage Door Header Lift System

The LintelLift System is a patented product that ensures garage door lintels or headers won't sag. When a garage door lintel fails, it causes the brick wall supporting it to sag, leaving a noticeable crack right about the garage door. The LintelLift System fixes this issue by adding support underneath the sagging lintel.

For new construction, The LintelLift System can be installed and pre-stressed prior to laying the brickwork, then released after mortar curing, to prevent future sagging.

Fixing Sagging Lintel and Cracks Above The Garage

The original cause of a sagging lintel and cracks is generally poor design. There must be an allowance at each end of the lintel for the expansion of the metal as it gets warmer. When the metal expands, it is pressing against the brick and mortar at each end, causing pressure at the weakest point. The middle of the lintel is a weak point as the pressure from above, pushes down on the lintel, with nothing supporting the bottom.

Warning Signs

Please look at the images below for some of the warning signs of a sagging lintel. These include stair-step cracks in the brickwork and gaps above the lintel where it is starting to bow.

Types of Lintel Repairs

We have two different options for our lintel repair services. They both offer the same quality of repair and add the same amount of structural strength, they difference is in the finishing details on the lintel. The standard repair includes flat trim pieces while the deluxe repair includes fluted columns on the sides and a crown molded top bridge section.

Engineered to lift a straight plane 1200 lbs. Heavier lifts are also available upon special order. The columns on the sides are designed with lift bolts that are adjusted by turning clockwise on the nuts. The bolts are contacted to the ends of the angle iron with a machined pivot. This allows the column to be stood up one end at a time and fastened to the existing wood door frames. Once both columns are vertical with the LintelLift under the sagging existing lintel, and outside the brick wall, the bolts are tightened down lifting the load while removing the camber. Once straightened, the sagging brick is now lifted and/or stabilized against a potential settlement. At this point, the raw iron will be covered with a vinyl kit specially made for fit.
