Concrete Sealing & Maintenance by O's Concrete

Crack repair, lift, resurface, seal.
The process

Here's exactly how we do this.

  1. 01

    Inspect + assess

    Not every crack means replacement. We grade the damage — surface, structural, or settlement — and recommend the cheapest fix that actually lasts.

  2. 02

    Clean + prep

    Pressure-wash, degrease, fill cracks with flexible polyurethane sealant. The base under sealer determines how long it lasts.

  3. 03

    Apply sealer

    Solvent-based acrylic or penetrating silane sealer depending on slab age and exposure. Two coats minimum. Tape and protect surrounding surfaces.

  4. 04

    Cure + walk-through

    Walk-on dry in 4 hours, full cure in 24-48 hours. We walk the slab with you when we're done so you see every spot we hit.

Backed by a real warranty

Premium package: 3-year warranty.
