24/7 Emergency Plumbing Services in St. Louis

When water is leaking, backing up, or spreading, minutes matter. Our St. Louis team provides 24/7 Emergency Plumbing to stop active damage, stabilize your system, and keep your home safe.

Call right away if you’re dealing with:

  • Burst, frozen, or actively leaking pipes anywhere in the home
  • Sewer backups in tubs, floor drains, toilets, or basements
  • Water heater leaks or tank failures (including rust-colored water or pooling around the unit)
  • Standing water in basements, utility rooms, or near electrical panels
  • Strong sewer or musty odors paired with slow drains or gurgling
  • Repeated toilet overflows or multiple fixtures clogging at once
  • Sump pump failures during heavy rain or snowmelt

While you wait for an emergency plumber, you can take a few steps to protect your home and belongings:

  1. Shut off the water: Turn off the main shutoff valve where the line enters the house or near the meter. For localized issues, use the shutoff valves under sinks, behind toilets, or near appliances.
  2. Kill power in wet areas: If water is near outlets, lights, or appliances, switch off the breaker for that area. Don’t step into standing water if you suspect live electricity nearby.
  3. Move valuables and soften the damage: Relocate furniture, rugs, boxes, and electronics away from wet areas. Lay down towels or buckets where safe to catch drips and limit spread.
  4. Don’t keep running problem fixtures: Avoid flushing suspect toilets, running clogged sinks, or using appliances that are leaking or backing up.
  5. Document what you see: Take photos and short videos of damage, standing water, and affected fixtures—these help with insurance and future repairs.

If you’re not sure whether your situation counts as an emergency, call 636-742-2533 and describe what you’re seeing. Our St. Louis emergency plumbing team will walk you through next steps, help you shut things down safely, and dispatch a plumber when needed.

Common Emergency Plumbing Problems in St. Louis Homes

Water moves fast when something goes wrong. St. Louis homes see a mix of older plumbing, clay sewer laterals, shifting soil, and big temperature swings—all of which create situations that turn into emergency calls. Here are some of the most common problems homeowners run into and the early signs to watch for:

  • Burst or Frozen Pipes: Freeze–thaw swings push pipes past their limit. Watch for sudden pressure drops, frost on exposed lines, or water staining on ceilings and walls. Keeping heat on and letting faucets trickle can help most systems ride out temperature dips. A seasonal inspection also lowers the risk of needing emergency pipe repair or dealing with major water damage.

  • Sewer Backups: Tree roots, heavy rain, and aging lateral lines push wastewater back into tubs, floor drains, and basements. Gurgling drains and sewer odors are early warnings. Inside the home, use drains only for what they’re made for—oil, grease, paint, wipes, and other products should never go down sinks or toilets.

  • Hidden Leaks Behind Walls or Floors: Corrosion, loose fittings, and aging supply lines create slow leaks that turn into major emergencies. Watch for damp drywall, warm spots in floors, musty odors, or unexplained jumps in your water bill. Routine checks around sinks, appliances, and basements help catch problems early before they spread.

  • Water Heater Failures: Sediment buildup, age, and pressure issues lead to leaks, no hot water, or tank ruptures. If you hear popping, see rust-colored water, or notice water pooling around the unit, it’s time to act by contacting an emergency plumber immediately.

  • Clogged or Overflowing Toilets: Main-line blockages, vent issues, and buildup cause toilets to overflow or back up into other fixtures. Slow flushes, bubbling, or rising water levels are early warnings. Avoid flushing wipes, hygiene products, or paper towels—anything not designed to break down can trigger an emergency and lead to toilet repair or replacement.

  • Backflow and Water Quality Issues: Storm surges, sudden pressure changes, or utility work can force unsafe water backward into your plumbing system. Cloudiness, unusual odors, or discolored water usually mean something needs attention right away. Annual backflow testing keeps things safe and reduces the chance of contamination.

  • Failed Sump Pumps: Heavy spring and fall rains, power interruptions, or aging pump components lead to standing water in basements. If the pit fills faster than the pump runs—or you hear grinding, rattling, or irregular cycling—call for help before flooding spreads. Testing pumps seasonally helps catch failures early.

Bottom line: Cloudy water, sour or musty odors, gurgling drains, banging pipes, or uneven pressure are all early warnings that something’s wrong behind the scenes. Even small symptoms can point to leaks, sewer issues, or pressure problems that lead to mold, rot, and structural damage if ignored.

These problems don’t stay small for long. If you’re seeing early signs, it’s better to get ahead of them before damage spreads to floors, drywall, or electrical systems. If you're experiencing any of these problems or expect you might in the future, don’t hesitate to call us at 636-742-2533 for emergency plumbing in the St. Louis area.

Emergency Plumbing FAQs

Homeowners often have questions when water is leaking, backing up, or moving where it shouldn’t. Here are the most common questions we hear about Emergency Plumbing in St. Louis:

What counts as a plumbing emergency?

Anything that risks flooding, contamination, structural damage, or loss of essential water service. Burst or leaking pipes, sewer backups, water heater failures, and standing water in basements all qualify. If you’re unsure, call and describe what you’re seeing—we’ll tell you if it’s urgent and what to do next.

How fast can a plumber get to my house?

For active leaks or backups, we dispatch immediately. Response times vary by location, but most homes in Greater St. Louis see same-day service—with priority given to issues that could cause flooding or sewer damage. You’ll get an arrival window and updates as we’re on the way.

What should I do while waiting for the plumber?

Shut off the water, kill power in wet areas, move valuables, and avoid running problem fixtures. If safe, catch drips with buckets or towels. Take photos for insurance and note where you first saw the issue—those details help speed up the repair once we arrive.

Can you give an estimate over the phone?

We can give a general idea for simple emergencies. For anything involving hidden leaks, sewer issues, or water damage, we diagnose onsite before quoting repairs. You’ll get clear options, plain-language explanations, and documented pricing before any work begins.

Do you handle water heater emergencies?

Yes. Leaking tanks, no hot water, pressure problems, or rust-colored water can all be emergencies. We service and replace standard and tankless units and bring the parts and tools needed for same-day repair when possible.

Why is my drain gurgling or smelling bad?

Gurgling usually means a partial blockage or venting issue. Sewer odor often points to a main-line problem or a failing trap. If multiple drains are affected, it’s a warning sign of a sewer issue that shouldn’t wait—especially if water starts rising in tubs or floor drains.

Do you work with insurance?

We document damage, provide written estimates, and supply the details insurers request. If you’re filing a claim for flooding, sewer backup, or water damage, we help make the process smoother by providing clear notes, photos, and repair documentation.
