Trusted plumbing, heating, and air conditioning in Larkspur, CA for canyon cottages, creekside homes, and downtown landmarks. Request service from our local team.
Larkspur is a town of small 1940s Heather Gardens bungalows, century-old Baltimore Park farmhouses, and redwood-shaded homes tucked into Baltimore Canyon — and each one ages differently. Down by Corte Madera Creek and the Greenbrae marshes, king tides and heavy winter rain push the water table up, while older galvanized supply lines and undersized systems show their years everywhere else. John Owens Services has worked these streets since 1986, so we know what a Larkspur house is likely hiding before we open the wall.

Low-lying areas near the creek and Greenbrae marsh sit on a high water table, and king tides plus winter rain overload older clay sewer lines and tree-root-prone drains. We can camera-inspect the line, clear blockages, and explain repair options.
