The lowest headline price may cover less work.
A removal-only quote may leave the stump and wood behind. Another may include grinding and haul-away but exclude new soil or lawn repair. Compare the same tree, access plan and finishing tasks before comparing totals.
What changes the price?
Tree size and condition, equipment access, surrounding structures, cleanup, permission requirements and urgency can all affect a proposal. Stump size alone does not describe access or the intended finished surface. This site does not publish an invented Dallas price average.
Keep the estimate useful.
Record inclusions, exclusions, tax, payment stages, scheduling assumptions and the procedure for additional work. The worksheet adds your own figures and an optional planning reserve. It is not a contractor quotation.
