Ways to lower your Baltimore price
- Keep the deck rectangular and under 200 sq ft where codes ease off.
- Frame with pressure-treated lumber and spend only on the visible deck surface.
- Build ground level — every foot of elevation adds framing, footings and railing.
- Schedule in fall when builders discount to keep crews busy.
- Skip fascia wraps and picture framing details that add labor with no structural value.
