How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Maryland using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. Maryland's RPP is 1.1 (national baseline = 100) and its BLS labor adjustment factor is 1.10. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.
adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)
RPP(Maryland) = 1.1 · BLS adj = 1.10

TOOLS TO RENT OR BUY
Build sequence
- 1
Remove the old door and frame and clean the rough opening.
- 2
Install a sill pan and flashing tape so any water drains out, not in.
COMMON MISTAKE
Skipping flashing is the top cause of rot under a new door.
- 3
Set the prehung unit, then shim it plumb, level, and square.
- 4
Screw through the jamb at the shims, then foam and caulk the gaps.
- 5
Install the lockset, adjust the threshold, and confirm a tight weather seal.
