Houston has no formal zoning and a large, competitive contractor pool, which keeps many trades at or below the national average. Hurricane season drives heavy demand for roofing and window work in late summer and fall, so scheduling outside that window can mean better prices and availability. The region's clay soil also makes foundation movement — and the plumbing and sewer-line repairs that follow — a recurring local expense.
