Columbia's affluent location between Baltimore and Washington brings a high cost of living and busy contractor demand to exterior projects.
- Rot- and mold-resistant or composite materials are favored in humid climates.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
How the cost is built
