Foundation Crack Repair in Knoxville, TN
Cracks are the most common reason people call about a foundation. Some are cosmetic and some are a sign of real movement. The pattern, width and whether the crack is growing tell the story.
Request a foundation inspectionTypes of cracks
Hairline vertical cracks in poured walls often come from shrinkage. Horizontal cracks in block walls and stair-step cracks along mortar joints usually mean pressure or settlement.
Watch and measure
Mark the ends of a crack with a pencil and date it. If it grows over a few months, it's active.
Sealing poured walls
Leaking cracks in poured concrete walls can be injected with epoxy or polyurethane to seal them.
Bowing block walls
Walls leaning inward can be stabilized with wall anchors, braces or carbon fiber, depending on how far they've moved.
Brick and veneer
Cracks in exterior brick often follow settlement in the foundation below. Repointing without fixing the cause won't last.
Inside the house
Drywall cracks above doors and windows and gaps at the ceiling can reflect movement below.
Water and cracks
Water through a crack makes basements damp and can freeze in winter, widening the crack.
When to worry
Cracks wider than about a quarter inch, cracks with one side offset from the other and cracks that keep growing deserve a professional look.
