Tree trimming cost by pruning type

Two quotes on the same tree are only comparable once you know which pruning type each one is for. Pick the type first; the price follows from canopy size and how the climber gets to the work.

The four pruning types, and their multipliers

Crown thinningSelective live branches throughout1.6×
Crown reductionLeaders shortened to suitable laterals2.2×

These are the ANSI A300 names. A crew that quotes in them is quoting to a specification; a quote that says "trim tree" is quoting to whatever they feel like on the day.

Access changes the machine as well as the hours

A pole saw from the ground is cheap and reaches almost nothing. A lift is fast where it can park and expensive to bring. A climber reaches everything and takes the longest. The calculator carries a different equipment rate for each because the equipment is genuinely different — a lift on site is a materially larger hourly cost than a chip truck.

Watch

Pruning near energised conductors is line-clearance work under a separate qualification. None of these rates apply to it and no general tree service should be quoting it.

Book it in the right month

The same job in late dormancy is cheaper and better for the tree than the same job in September, and for oaks and elms the wrong month is not a preference but a disease risk. Check the pruning calendar before you accept a date, and read when to prune for the reasoning.

If the tree's problem is a weak union rather than its size, pruning is the wrong purchase — see cabling and bracing.
