Solving the Root Cause of Cracked Brick in Elmhurst
If you've noticed diagonal stair-step cracks in the brick above your windows or doors, the problem almost certainly isn't the mortar, it's the steel lintel behind it. Steel lintels were standard construction in Elmhurst homes built between the 1940s and 1980s, and after decades of moisture exposure, they corrode. Expanding rust creates the pressure that cracks the brick. Tuckpointing alone won't fix it.
Elmhurst's post-war brick homes, the ranches, split-levels, and colonials built along York, Spring Road, and throughout the residential streets east of downtown, were almost universally built with steel angle lintels over window and door openings. These lintels are now 50–70 years old, and the protective mortar that was supposed to keep them dry has long deteriorated in most cases. The result is a predictable pattern of corrosion-driven cracking common in homes of this era.
Lintel replacement is a structural masonry repair that requires careful brick removal, proper shoring of the wall above the opening, lintel sizing and installation, and precise brick replacement to restore the original coursing. This is not a job for general handymen. Our crews bring 50+ years of combined masonry experience to lintel repair and replacement work.
