San Rafael runs from its busy downtown out to the hillside neighborhoods, and the housing changes a lot as you go. CNTRline Plumbing Service works on the Victorians in Gerstle Park, the mid-century Eichlers in Terra Linda, and the homes up through Montecito and Dominican. We come over from Rohnert Park and know how different each of these homes is under the floor.

Plumbing in San Rafael

Gerstle Park holds some of the oldest houses in the city, and Victorian-era plumbing there tends to be corroded steel or cast iron on borrowed time. Terra Linda is a different animal. Those Eichlers were built with radiant slab heating and plumbing routed through the concrete, so a leak there needs someone who understands the design before they start cutting.

Finding a slab leak under an Eichler in Terra Linda takes electronic detection, not a jackhammer and a guess, and that is exactly how we approach it.

Neighborhoods we cover: Downtown, Gerstle Park, Terra Linda, Montecito, Dominican.

ZIP codes: 94901, 94903.

Questions

Common questions from San Rafael homeowners

Yes. Marin has roughly 1,700 Eichlers, most of them in Terra Linda, Marinwood, and Lucas Valley here in San Rafael, built between 1955 and 1966 on concrete slabs with hydronic radiant heating. A slab leak or a failed radiant loop in one of those houses is a different animal than the same repair in a raised foundation home, so we locate it properly before anyone cuts concrete.
Quotes are free and you get the price before the work starts. In San Rafael, drain clearing typically runs $125 to $600, main line cabling $250 to $600, and a tank water heater replacement $1,800 to $3,600 installed. Larger work like a sewer spot repair lands between $1,500 and $4,500, and we put the number in writing either way.
