San Jose has thousands of mid-century Eichler homes in Willow Glen and Cambrian, many with radiant heating pipes embedded in the concrete slab. Leaks in those pipes are hard to find and can soak flooring from below. Older bungalows in the Rose Garden and Naglee Park sit on raised foundations with crawlspaces.
Licensing in California: California requires contractors on jobs of $500 or more (labor and materials) to be licensed by the Contractors State License Board (CSLB). Check the license on the CSLB website.

Other risks in San Jose
Radiant slab leaks in Eichler homes
Aging copper or steel radiant tubing in Eichler slabs can leak, causing warm or wet floors and hidden damage.
Earthquake risk
The 1989 Loma Prieta earthquake damaged homes across the South Bay, and quakes can break pipes and water heaters.
Summer AC condensate leaks
Hot inland summers keep AC systems running, and clogged condensate lines overflow into ceilings.
Older crawlspace homes
Bungalows in the Rose Garden, Naglee Park and Willow Glen often have plumbing running through crawlspaces, where slow leaks can soak subfloors and grow mold before anyone notices.
Signs you need sewage & biohazard cleanup
- Water or waste coming up through floor drains, toilets or tubs

Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in San Jose?
Cleanup doesn't. Structural, plumbing and electrical repairs need permits from the City of San Jose Building Division.
How do I know if my San Jose Eichler has a radiant heating leak?
Signs include warm spots or damp areas on the floor, a boiler that keeps losing pressure, and unexplained water bills. A leak detection specialist can locate it.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
