How fast can a plumber get to my emergency?

Our emergency plumbers typically arrive within 1–2 hours in the San Mateo 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 Mateo 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 Mateo 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 Mateo's mature tree canopy — especially older neighborhoods like Land Park, East San Mateo, and Curtis Park — makes root intrusion particularly prevalent.

How much does water heater replacement cost?

Water heater replacement in San Mateo costs $1,200–$4,500 depending on the type. Standard tank water heaters run $1,200–$2,500, tankless models $2,500–$4,500. Heat pump water heaters qualify for SMUD rebates up to $4,000.

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.

Tom and his team are great to work with. Performed some retrofit work at a food processing plant for me and knocked it out of the park. Even when unexpected issues arose, they handled them with the highest level of professionalism. Would not hesitate to use these guys again

★★★★★Ethan Stock4 years agovia Google

I have used Mid-Peninsula probably a dozen times over the past 10 years, ranging from an emergency sewer backup to a broken water main to sink, toilet, and faucet repairs in my house. They are very professional, very prompt, communicate clearly, and do great work at a fair price. Super happy with them as my 100% go-to plumber.
