How fast can a plumber get to my emergency?+
Our emergency plumbers typically arrive within 1–2 hours in the San Anselmo metro area. We're available 24/7, including weekends and holidays. Call immediately if you have active flooding or a gas leak.
What should I do while waiting for the plumber?+
Turn off the water main valve (usually near your water meter or where the main line enters your home). If there's a gas leak, leave the house and call 911. Place towels or buckets to catch water and move valuables away from affected areas.
How much does drain cleaning cost?+
Drain cleaning in San Anselmo typically costs $125–$500. A single clogged drain costs $125–$250 to clear. Main sewer line cleaning with hydro-jetting runs $250–$500. We provide upfront pricing before starting.
What causes drains to clog in San Anselmo homes?+
The most common causes are grease and food buildup in kitchen drains, hair and soap scum in bathroom drains, and tree root intrusion in main sewer lines. San Anselmo's mature tree canopy — especially older neighborhoods like Land Park, East San Anselmo, and Curtis Park — makes root intrusion particularly prevalent.

What SMUD rebates are available for water heaters?+
SMUD offers up to $4,000 in rebates for heat pump water heater installation. Combined with federal tax credits, you could save $4,000–$6,000 on an energy-efficient upgrade. We handle all rebate paperwork.
