24/7 Emergency Plumber in Altadena, CA
Live dispatch around the clock for burst pipes, water heater failures, sewer backups, and gas line emergencies. Same-day response across Altadena and the SGV.
An emergency plumber handles plumbing failures that can't wait for a normal appointment. That includes anything actively causing water damage, gas leakage, sewage exposure, or loss of essential household water service. We provide 24/7 emergency plumber response across Altadena and the surrounding San Gabriel Valley, with a live dispatcher answering calls around the clock and after-hours plumber availability for weekend plumber, holiday, and overnight calls. The phone goes to a person, not a callback queue.
What counts as a plumbing emergency
Not every plumbing problem requires immediate after-hours response. A slow drip from a faucet can wait until morning. A failing water heater that hasn't fully ruptured can usually wait a few hours for a daytime appointment. Knowing what's actually urgent helps you decide whether to call us at 2 a.m. or schedule for the morning.
Always call immediately for these:
- Burst supply lines or active flooding from any pipe
- Failed water heater tank with significant water release
- Sewer backup into showers, tubs, or floor drains
- Gas leak smell at any appliance or supply line (call gas utility first)
- Main shutoff valve failure or stuck shutoff during a leak
- Frozen and split pipes during a cold snap
- Toilet overflow that won't stop after the supply is shut
Usually can wait until morning:
- Slow faucet drips with no other symptoms
- Single slow-draining sink that the rest of the house isn't affected by
- Loss of hot water if cold water still functions
- Running toilet you can isolate by shutting the toilet supply
If you're unsure, call. We'll talk through what you're seeing and tell you honestly whether you need emergency leak repair tonight or whether a morning appointment will do.
Our emergency response process
When you call our 24/7 emergency plumber line, the process is the same every time. We've simplified it to make sure things move fast.
Live dispatcher takes the call
A real person answers (844) 981-1691 at any hour. They take your address, ask what's happening, and confirm whether you've shut off the water at the main or at a local valve. If you haven't, they walk you through it while routing a technician.
Technician en route within minutes
For most Altadena and adjacent SGV addresses, we have a tech moving within 15-30 minutes of the call. Drive time depends on time of day and where in the service area you are. Most calls in Altadena, Pasadena, and Glendale get an on-site response within 60-90 minutes during the day and 90-120 minutes overnight.
Diagnosis and upfront price before work starts
The technician assesses the problem on arrival and gives you a firm price before any repair work begins. You don't get a small dispatch fee on the phone and then a surprise bill at the end. Emergency drain cleaning, emergency water heater repair, or emergency sewer repair all get the same upfront pricing approach as standard daytime calls.
Repair completed, site cleaned
We complete the work and leave the site clean. Permitted work is filed with the LA County Department of Public Works as required. You get documentation of what was done.
What we handle on emergency calls
Emergency calls in Altadena and the SGV cover a predictable range of failures. The list below is what makes up the bulk of our after-hours plumber work.
Burst pipes and supply line failures. Copper pinhole ruptures, failed galvanized fittings, and PEX fitting failures all cause active leaks that need immediate isolation and repair. We carry standard fitting and pipe stock for same-visit repair on most calls.
Water heater emergencies. A tank that has split typically releases its full volume (40-75+ gallons) before draining. We shut down gas or electric service to the unit, drain the remainder safely, and quote replacement on the spot if the tank is gone. Emergency water heater installation often follows.
Sewer backups. Mainline blockages that back sewage into fixtures need urgent emergency drain cleaning to restore service and prevent further contamination. We use augers and, where needed, mainline cameras to identify the cause once flow is restored.
Gas leaks. After the gas utility has shut off and verified safety, we repair the gas line or fitting that caused the leak. We pressure-test the line, repair as required, and recertify the system before re-energizing.
Frozen pipes. Rare in Altadena's mild winters but not unheard of during cold snaps, especially in unheated crawlspaces or exterior wall runs in older homes. We thaw safely and repair any split sections.

Other urgent plumbing situations we handle
Beyond the headline emergencies above, we respond to a wider set of urgent plumbing inspection and repair needs: pipe winterization before short cold snaps, post-storm sewer overflow inspection, water meter leak verification after suspiciously high bills, plumbing inspection before real estate closings on short timelines, and active leak isolation for properties owned by absentee homeowners. We also handle commercial emergency response for restaurants and offices on the SGV's commercial corridors. For statewide emergency plumbing guidance, the California Department of Water Resources publishes resources on shutoff valves and household water emergencies.
Frequently asked questions
What counts as a plumbing emergency?
Anything actively causing water damage, gas leakage, sewage backup, or loss of essential service to a home counts as an emergency. Common examples include burst supply lines, failed water heater tanks, sewer backups into fixtures, gas leak smell at appliances, frozen and split pipes during cold snaps, and main shutoff valve failure.
How fast can you respond in Altadena?
For most emergency calls within Altadena and adjacent SGV cities, we can have a technician on site within 60-90 minutes during the day and 90-120 minutes overnight. Response times can vary during major storm events or large-scale events when call volume spikes.
What's the first thing I should do if a pipe bursts?
Shut off the main water valve to the home. It's usually at the front of the property near the curb or on the side of the house near the meter. Then call us. Stopping the water flow at the main is the single most important step to limit damage before a plumber arrives.
Do emergency calls cost more?
There is a dispatch fee for after-hours service that reflects the cost of on-call availability. We tell you the dispatch fee on the phone before sending a technician. The repair price itself is quoted before work begins, the same as on standard service calls. We don't add surprise overtime charges.
What if I smell gas at my water heater or stove?
If you smell gas, leave the house and call your gas utility first. They will isolate the source. After the utility makes the property safe, we can repair the gas line, fitting, or appliance connection causing the leak. Don't operate any electrical switches or use phones inside the home until the utility confirms it is safe.
Will the emergency line really be answered at 2 a.m.?
Yes. (844) 981-1691 routes to a live dispatcher around the clock. We don't use an answering service that takes a message for a callback the next morning. If you call, you reach a person who can get a technician moving.
