Showing up where the lake country gathers.

O'Leary Plumbing, Heating & Electrical is part of the lake-country community — sponsoring events, supporting high-school mentors, and showing up where the lake-country towns gather across Walworth, Waukesha & Racine County.

Where We Live

Three counties. One lake-country home.

Since 1958, O'Leary's home base has been East Troy. The crews leave our shop every morning and head out across Walworth, Waukesha and Racine County — Elkhorn, Lake Geneva, Williams Bay, East Troy, Mukwonago, Burlington, Whitewater, Twin Lakes, Lauderdale Lakes, Delavan and all the smaller lake towns in between.

We work on the homes around the lakes our kids learned to swim at. That's not a slogan — it's just the address.

What We Believe In

A few things you can count on from O'Leary.

Hire local. Stay local.

Our managers and most of our techs grew up in the lake-country towns we serve. We recruit from East Troy, Waterford, and Elkhorn high schools through mentor programs, and we keep our people for the long haul.

Show up before we're asked.

Brooklife Church's community assistance program, CBS 58 public-safety segments during polar-vortex weeks, water-wagon support at the East Troy Bluegrass Festival — we're usually the trade name at the table because we care, not because anyone asked us to.

Stay independent.

Three generations of O'Learys, never sold to a private-equity rollup. That's how we stay accountable to the same lake-country families we've worked with since 1958.
