Enter the deck footprint
Choose the deck material and enter length, width, elevation, railing type, and railing height.
Estimate deck cost before you draw the footprint.
Start with the material, size, elevation, railing, stairs, connection, access, and demolition assumptions. Then use the map estimator to draw the real deck and prepare a clearer quote request.
Add stairs and site assumptions
Include stair flights, width, angle, stair railing, freestanding framing, footings, access, and demolition.
Move to the property map
Open the estimator with the calculator choices carried over, then draw the real deck footprint and place stairs.
Deck cost calculator
Your planning estimate updates immediately as you change the deck footprint, elevation, railing, stairs, connection type, and access assumptions. Add a location to show approved local cost factors.

Use this estimate as a starting point
This estimate is not localized yet. You can still draw it on the map, or add an address first for local context.
What changes the deck estimate?
The calculator starts with your material and footprint, then adds common structural and access assumptions. If you add a location, it can show approved local adjustments before you move into the map estimator.
Material and square footage
Pressure-treated wood, composite, PVC, and premium hardwood use different installed planning ranges.
Elevation and framing
Higher decks can increase framing, railing, stair run, footing, and labor requirements.
Stairs and railings
Stair count, stair width, stair angle, railing type, and railing height can move the estimate quickly.
Local context
Published local factors can adjust the estimate using wage, demand, regional cost, weather, soil, permit, and approved pricing data.
