Formula
Calculation logicBudgeting and Scheduling a Lock Project
Build the budget in three bands
Parts = locks times tier price. Labor runs $0 DIY, ~$160 scheduled, ~$340 emergency. Add a prep-risk adder for painted, misaligned, or odd-bore doors, then hold 30% above base for surprises.
Schedule the work in order
Remove and inspect, fix prep, install, align the strike, test ten cycles, then do smart setup last. First-time DIY takes about twice a pro. Demand a ten-cycle test and haul-away before paying.
