One name on the truck, since 1996.

Koehler Plumbing has been working on houses in Powell since 1996. It started the way most trade businesses around here started - one licensed plumber, a truck, and a phone number handed between neighbors - and it has stayed deliberately close to that shape. Keith is a veteran, the business has been veteran-owned from the first day, and the name on the invoice belongs to the person who is accountable for the work.

Working the same county since 1996 buys a specific kind of knowledge. We know which subdivisions went up in which decade and what was plumbed into them: the copper that went into the 1990s builds off Sawmill and Home Road, the galvanized still hiding in older Worthington and Delaware houses, the polybutylene that turned up in central Ohio between the late seventies and the mid nineties. We know what the water in this part of Ohio does to a water heater, a faucet cartridge and a tankless heat exchanger, because we have been pulling them apart here since before most of the franchises had a local phone number.

We work on homes only - single-family houses, townhomes and condos. No commercial buildings, no furnaces, no electrical panels. Seven of the companies you will find above us in a search sell three trades at once; we sell one, and that is the whole point. If a job genuinely belongs to somebody else, we will tell you who to call rather than learn on your house.

Pricing is the other thing people ask about. You get a number before anything is opened, ordered or removed, and it does not move without a conversation first. No hourly meter running while you wonder what it is costing, no discovery of a second problem halfway through that happens to double the invoice.

The license is OH License #23683, and you should check it - ours or anyone else's. Ohio publishes a public lookup at elicense.ohio.gov, and any plumber who hesitates to give you a number to type into it is telling you something.
