How much does it cost to deal with a tree is on the power line / there are sparks outside?

Frequently nothing to you for the utility-owned portion of the line, which is the single biggest cost variable here. UNVERIFIED: exactly where a given Indiana utility's responsibility ends — the general industry pattern is that the utility owns the line to the connection point while the homeowner owns the mast, weatherhead and everything past it, but that boundary is set by each utility's own tariff and I could not verify the central-Indiana specifics. Where the work is yours, only a line-clearance qualified arborist may work within the minimum approach distances under ANSI Z133, and that qualification prices meaningfully above general tree work.
