Parking Lot Sealcoating in Phoenix, Arizona

Coal-tar or asphalt emulsion sealcoat application to protect and extend the life of existing asphalt. In Phoenix, pricing typically runs $0.12 to $0.29 per sq ft (single coat with crack fill) — about 4% below the national average. Extreme UV and 115°F summer surface temperatures degrade binder unless heat-resistant mix designs are specified. Caliche layers require over-excavation on many Valley sites — subgrade assessment is non-negotiable. Permitted through Phoenix Planning and Development; typical review window 6-10 weeks for commercial site plan review.
