No water or a trickle from a faucet during freezing weather. Here's what to do about frozen pipes in San Francisco Bay Area — including the local factors that change the advice.
Do this right now
Open the faucet
Open the affected faucet slightly. Flowing water — even a trickle — helps melt ice and gives it somewhere to go.
Warm the pipe gently
Hair dryer, heating pad, or warm (not hot) towels on the frozen section, working from the faucet back toward the blockage. Never an open flame or heat gun on high.
Check for leaks as it thaws
Watch closely — the real danger is a split you can't see until water flows. Have the main shutoff location ready.
Know when to stop
If you can't find the frozen section, if it's inside a wall, or if thawing reveals any leak — stop and call.
Call before it bursts
Call (844) 699-1165. A pro can thaw safely, check for splits, and insulate the vulnerable runs so it doesn't happen again.

What makes frozen pipes different in San Francisco Bay Area
- In San Francisco Bay Area, freezes are uncommon, but uninsulated pipes in old basements and crawlspaces stay vulnerable
- Victorians, Edwardians, and pre-1970s housing stock with aging plumbing systems — pipes in these spots freeze first.
- earthquake country with cool, damp microclimates
- Shared walls, stacked flats, and condo HOAs mean shutoffs often affect neighbors — access coordination matters
