We Fix Ugly Concrete · Crack repair & sealing
Concrete Crack Repair & Sealing in Phoenix, AZ
Cracks let water under your concrete and get bigger every season. We repair cracks, fix failed expansion joints, and seal concrete to protect it from Arizona’s sun and monsoons.
Almost all concrete in the Valley cracks eventually. Expansive clay soils swell during monsoon season and shrink as they dry, and 115° summers expand and contract the slab every day. Small cracks are normal, but left alone they let water in, widen, and lead to settling, heaving, and stains. Repairing cracks early and sealing the surface is the cheapest way to make concrete last.
Does your pool deck look like this?
Cracks like these let water under the slab and only get worse. We repair the cracks, fix the cause, and resurface the deck so it looks new again.
Repair, reseal, or resurface?
Crack repair. Cracks are opened, cleaned, and filled with flexible or structural repair material depending on whether they’re still moving.
Expansion joints. Failed joints between slabs, and at the pool coping, are cleaned out and resealed so the slab can move without cracking.
Sealing. A penetrating or topical sealer protects concrete and decorative finishes from water, stains, and UV fading.
Resurfacing is the next step when cracks and stains are widespread. See pool deck resurfacing.

Why cracks keep coming back
Concrete moves. A rigid patch on a crack that opens and closes with the seasons will crack again. The fix is matching the repair to the crack: flexible sealant for moving cracks and joints, structural repair for stable ones, and fixing drainage that’s feeding water under the slab.
Around the pool, the expansion joint between the deck and coping is the most important joint on your property. If it fails, water gets behind the coping and tile. See coping repair.
