Our emergency plumbers typically arrive within 1–2 hours in the Grass Valley 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.

What causes drains to clog in Grass Valley 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. Grass Valley's mature tree canopy — especially older neighborhoods like Land Park, East Grass Valley, and Curtis Park — makes root intrusion particularly prevalent.
