Brand-specific planning tool
LP SmartSide cost calculator
Start with the published LP SmartSide planning range, then adjust the property inputs that affect labor and scope.
Built from the published rate cardThe approved lp smartside baseline is $5–$11 per square foot installed before the separately selected removal adjustment. The calculator does not turn that planning baseline into a contractor quote.
SidingPricing is not affiliated with, endorsed by, sponsored by, or authorized by the named manufacturer. Brand names are used only to identify the approved rate-card material category.
How this estimate is calculated
The calculator multiplies the selected home size by the approved material baseline, then applies the rate card’s labor-only adjustment for story height, project complexity, and an approved state multiplier when the ZIP maps to one. Materials remain on the national baseline; the location adjustment is not applied to them.
Removal is kept separate. When selected, the calculator adds the approved non-hazardous old-siding removal-and-disposal range of $1–$3 per square foot once. That prevents the common mistake of charging removal inside the installed baseline and then adding it again.
Inputs that should match the home
Exterior area starting pointHome square footage helps you begin, but contractors should measure siding wall area, openings, gables, waste, and attached structures before setting final quantities.
Stories and complexityStory height and the simple, standard, or complex selection affect the labor component because access, cuts, transitions, and safety time can change installation effort.
ZIP and state labor adjustmentA covered ZIP applies only the approved labor adjustment. If no approved state value applies, the calculator uses the default multiplier rather than inventing a local rate.
Removal selectionChoose removal only when existing siding must be taken off. The result does not assess hazardous materials, substrate condition, or hidden damage.
What to confirm in the written scope
Use the result to start a contractor conversation, not to skip one. Ask each installer to specify the siding product and finish, removal and disposal, wall preparation, wrap and flashing, trim, repairs, permits, change-order process, cleanup, and workmanship or manufacturer warranty terms. Compare the scope as carefully as the total price.
LP SmartSide is modeled separately from the generic engineered-wood category. The result is planning information, not a brand or contractor quote.
