Red flags

When should you stop and call a professional?

Six signs that the problem is past DIY. Turn the system off and pick up the phone — running a system with these issues turns cheap repairs into expensive replacements.

  • Cracks wider than half an inch or growing

    Indicates structural movement or base failure. Patching without diagnosing the cause makes the problem worse.

  • One side of a crack visibly stepped

    Settlement crack. Needs polyurethane lift or replacement, not surface filler.

  • Slab rocking or pumping water

    Void under the slab. Continuing to use the slab will crack it further. Needs lift or replacement.

  • Rust stains pushing through the surface

    Rebar corrosion from below. Needs cut-out and partial pour with epoxy-coated bar — not just a topical patch.

  • Wet basement or crawl space below the slab

    Water is finding a path through cracks. Structural issue that requires drainage diagnosis before any patch holds.

  • Foundation cracks over 1/8 inch

    Foundations carry the structural load. Even small cracks should be evaluated by an engineer or experienced contractor before injection or patch.
