What it costs to waterproof brick in Broken Arrow

Waterproofing the brick on a typical Broken Arrow house costs $1,000 to $3,500 for a penetrating silane and siloxane water repellent, and $2,500 to $7,500 when the mortar joints, spalled brick or weep holes have to be repaired first. Most homes here are brick veneer over a wood frame on a slab, built between 1975 and 2005, and the brick itself is not what leaks. Water gets in through cracked mortar joints, through the slab line where weep holes were skipped or mortared shut, and through a chimney crown that has split. The clay under the slab swells every wet spring and shrinks every dry August, so joints that were tight in 2005 are open now. We test the wall with a hose before quoting, fix what is actually letting water in, then seal the whole elevation with a breathable repellent that carries a 10 year manufacturer warranty. Every price is on the cost page before you call.

Why brick walls leak in Green Country

Four things work on a masonry wall here that a wall in a drier, flatter place never sees. Fix the one that is actually active and the wall dries out. Seal over it and the wall fails from the inside.

Clay that moves the wall

The soil under Broken Arrow is rich in montmorillonite clay, which can swell 10 to 15 percent when wet and shrink as much in a dry August. Oklahoma State University Extension notes that soils over 30 percent clay expand and contract dramatically between wet and dry. The slab rides that movement, and the brick veneer on top of it cracks in stair steps at the corners and around windows. Those cracks are the water path.

Freeze and thaw on a wet wall

Tulsa gets about 43 inches of rain a year and dozens of nights below freezing each winter. A brick that goes into December wet freezes, the ice expands, and the face pops off in a plate. That is spalling, and it is why the north walls of older houses look worse than the south walls. A breathable repellent keeps the brick dry enough that the freeze has nothing to work on.

Weep holes that were never there

Brick veneer is a drainage wall. Water is meant to run down the back of the brick, hit a flashing, and leave through open joints at the base course. Houses here built before the mid 2000s mostly have no flashing and no weep holes, and newer ones often have them mortared shut. The water sits against the slab edge and wicks into the framing. Read the weep hole guide before anyone sells you sealer.

Salt coming out as white powder

Efflorescence is the salt that water carries through mortar and brick, left on the face when the wall dries. It is not harmful by itself, but it is proof that water is moving through the masonry, and the same crystals growing under the face will eventually spall it. Cleaning it without fixing the water path brings it back by spring. Our efflorescence guide explains what the pattern tells you.
