Not every stucco crack is an emergency, but every crack is a path for water. M & J Plastering and Stucco Corp tells you which cracks are cosmetic, which are letting water in, and repairs both so the wall stays dry through the next rainy season.

In Florida, stucco cracks come from house settling, thermal movement, rusted lath, bad original installation and, most often, water. Once water gets behind the stucco it rusts the lath, rots the sheathing on frame walls and shows up as stains, bubbles and soft spots. Patching over the crack without fixing the path of the water means repairing it again next year.
Sound familiar? Ana in Kendall painted over a crack twice and it came back both times. Robert in Miami Shores has a brown stain under a window that grows after every storm. A landlord in Miami Gardens found stucco that crumbles when touched near the base of the wall. In each case we open the damaged area, fix the lath, flashing or sealant that let water in, re-stucco and match the finish.

Elastomeric crack-bridging coatings

Hairline cracks under 1/16 inch are usually cosmetic. Wider cracks, step cracks that follow block lines, cracks with stains or bubbling nearby, and hollow-sounding areas mean water is getting in and should be repaired soon.
Settling, thermal expansion and contraction, rusted lath, improper mix or cure, missing control joints and, above all, water intrusion through windows, roof edges and unsealed penetrations.
We remove the damaged stucco, replace rusted lath and rotted sheathing, correct the flashing or sealant that let water in, apply new base and finish coats and match the texture before painting.
Caulk is a temporary fix for hairline cracks and often shows through paint. For lasting results we open and patch the crack with stucco and bridge it with an elastomeric coating.
Minor crack repairs typically run a few hundred dollars; moisture-damage repairs depend on how much stucco, lath and sheathing must be replaced. We quote a fixed price after a free inspection.
Sudden events like storms or impact are often covered; gradual deterioration usually is not. We provide the photos and written assessment adjusters ask for.
Stucco needs to cure before paint, usually several days depending on thickness and weather. We schedule the repaint so the repair and the wall look uniform.
