How fast can a plumber get to my emergency?

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

How much does water heater replacement cost?

Water heater replacement in Union City 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.

Remodeled showroom! Always changing it up to being in the best and most up to date displays as possible. Great guys that know their stuff and will do the best they can to help you get the right product and style for the space/job.

Great place with very high quality products. I'm not a pro and I just bought materials as an owner builder - they gave me good advice and they delivered several 20ft pipe sections for free. However - and the reason for four stars - sometimes the wait can be really long but what really disappointed me is the inconsistency in pricing. On a Saturday I bought some fittings. On the following Tuesday, I bought some more of the same and the price increased 40%. I don't mind spending good money for quality materials, but why has the price be so random...
