What’s different about Milwaukee
Milwaukee is Wisconsin's largest market, where a deeper contractor pool, older housing stock, and heavy lake-effect snow shape exterior project costs.
- Footings have to reach below the frost line, so deeper excavation adds cost.
How the cost is built
Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.
