Quick Answer
An emergency plumber is a licensed professional available outside normal hours to stop active water or gas damage — a burst pipe, a sewage backup, a failed water heater, or a gas smell. New Pro Plumbing answers 24/7 across West LA, arrives fast from our Mar Vista base, and quotes a flat rate before any work begins.
A plumbing emergency is any failure that is actively damaging your property or threatening health and safety and cannot safely wait for business hours. This page is part of our complete guide to residential plumbing services across West Los Angeles. In practice, the calls that bring a New Pro plumber out at night fall into a short, predictable list: a supply line that has burst or sprung a fast leak, a sewer main backing up into tubs and floor drains, a water heater that has split and is flooding a garage, an overflowing toilet that is the home’s only one, or the smell of natural gas. Because so much of the Westside was built between the 1920s and the 1960s, the underlying causes are usually age-related — corroded galvanized supply, tired copper, and clay or cast-iron sewer laterals invaded by ficus and sycamore roots.
A plumbing emergency is a sudden plumbing failure — flooding, a burst or leaking pipe, a sewage backup, a loss of all water or all toilets, or a gas leak — that is actively causing damage or risk and needs a licensed plumber now, not tomorrow.
Before help arrives, the single most valuable thing you can do is stop the water. Every home has a main shutoff — usually a valve near where the water line enters the house or at the meter near the curb — and most water heaters and toilets have their own local valves. We keep a short guide on the emergency water shutoff so you can act in the first sixty seconds, and our dispatcher will talk you through it on the call.
High-value homes and a tight rental and condo market mean a small overnight leak can become a five-figure restoration claim by morning. The U.S. EPA notes household leaks waste huge volumes of water and worsen quickly when ignored (EPA WaterSense). A licensed plumber who can isolate the failure at 1 a.m. is the difference between a quick repair and a gutted floor.
The most common after-hours plumbing emergencies in West LA are main-line sewer backups, burst or leaking supply pipes, and failed water heaters. Each has a different cause and a different fix, and knowing which one you have helps you describe it clearly when you call.
Sewer backups usually announce themselves with multiple slow or gurgling drains and water rising in the lowest fixture — a downstairs tub or a floor drain. On older clay and cast-iron laterals, the culprit is almost always root intrusion or a main-line stoppage. A burst supply line, by contrast, floods continuously until the water is shut off.
If water or sewage is spreading, if you have no working toilet, if a water heater is leaking onto electrical, or if you smell gas, call now. A single dripping faucet or a slow drain can usually wait for a scheduled visit — though it is still worth fixing before it grows.
Pipe burst? Sewage backing up? We answer 24/7.
Call (310) 663-7666Before the plumber arrives, shut off the water at the main or the nearest local valve, move valuables away from the water, and avoid using any drains if a sewer backup is suspected. These three steps limit the damage and make the repair faster.
Keep everyone away from standing water near outlets or panels. If a water heater is leaking, turn off its gas or breaker and its cold-water inlet. Our before the plumber arrives checklist covers the rest.
New Pro quotes a flat rate before any emergency work begins, so you are never billed by the hour while water is on the floor. We diagnose the problem, show you what we found, and put the price in writing first — the same honesty we bring to every call. See our overview of emergency plumbing cost for typical ranges and what drives them.
It is 11 p.m., a pipe has let go, and water is spreading toward the hardwood. The homeowner cannot find the shutoff and every minute means more damage.
A licensed New Pro plumber answers immediately, talks the homeowner through the main shutoff, and is dispatched from nearby Mar Vista with a stocked truck — with a flat price quoted before work starts.
The leak is isolated and repaired the same night, the cause is identified, and the homeowner gets a written record for any insurance claim — one trip, one bill, one resolved problem.
If you smell gas, treat it as a life-safety emergency: leave the building, do not switch anything on or off, and call SoCalGas or 911 from outside per SoCalGas safety guidance. Once the utility makes the area safe, New Pro handles the gas leak detection and repair, plus any re-inspection the city requires.
We pressure-test the system, repair or replace the failed section, and coordinate the LADBS re-inspection so your gas is restored correctly and legally.
The Bottom Line
A plumbing emergency rarely waits for a convenient hour. The right response is simple: shut off the water or gas, get everyone safe, and call a licensed plumber who actually answers. New Pro Plumbing answers 24/7 across West LA, arrives fast from Mar Vista, and quotes a flat rate before we start.
Yes — New Pro Plumbing answers calls 24 hours a day, six days a week, with Sunday hours from 9am to 5pm and 24/7 availability for true emergencies. A burst pipe or sewage backup does not keep business hours, so neither do we. When you call after hours, a real person helps you stop the immediate damage and dispatches a licensed plumber from our Mar Vista base. Call (310) 663-7666.
Shut off your water immediately — either at the fixture’s local valve or at the home’s main shutoff near where the line enters the house or at the meter. Then move valuables clear of the water and call us. Shutting the water off is the single biggest factor in limiting damage, and our dispatcher will guide you to the valve if you are not sure where it is.
Because we are based in Mar Vista and focus on the Westside rather than all of Los Angeles County, our response times across neighborhoods like Santa Monica, Culver City, Venice, and Brentwood are typically short. Exact timing depends on traffic and current call volume, so we will give you an honest estimate when you call rather than a generic promise.
We quote a flat rate before any work begins, even on emergencies, so you always know the price before we start — no hourly meter running while water is on the floor. Emergency and after-hours work can carry different pricing than a scheduled daytime visit; we explain exactly what applies to your situation up front and put it in writing.
Usually not — a single slow drain or a minor drip can typically wait for a scheduled appointment, though it is worth fixing before it grows. Treat it as urgent if water or sewage is actively spreading, if you have lost all water or all working toilets, if a water heater is leaking near electrical, or if you smell gas. When in doubt, call and describe it; we will tell you straight whether it can wait.
Leave the building right away, do not touch any light switches, appliances, or phones inside, and do not light anything. Once outside, call SoCalGas or 911. A gas leak is a life-safety emergency that the utility addresses first. After they make the area safe, New Pro handles the leak detection, repair, and any required city re-inspection to restore your gas correctly.
Yes. We identify and document the cause of the failure, show you what we found, and provide a clear written record of the diagnosis and repair, which is exactly what most homeowners’ insurers ask for on a water-damage or sudden-failure claim. We are not insurance adjusters, but our documentation gives you and your carrier an accurate, professional account of what happened.
Yes — New Pro Plumbing is licensed by the California Contractors State License Board (CSLB #974600) and insured, and you can verify our license at the CSLB website. Using a licensed plumber matters most in an emergency, when shortcuts and unpermitted fixes can leave you with code violations, repeat failures, or denied insurance claims down the line.
