Burst pipe flooded my house: what do I do first?

Short answer

Shut off the main water valve first. If water is near outlets or the panel, leave the power off and stay out of it. Have a plumber fix the line. Take photos, then get everything drying within 24 to 48 hours, because wet drywall, baseboards and floors can grow mold after that. We extract the water, dry the house and rebuild.

Signs to look for

  • Water pooling under a sink, behind a toilet or next to the washing machine
  • Musty smell in a cabinet, closet or wall that gets worse each day
  • Drywall that feels soft, or paint that bubbles or stains
  • Baseboards swelling or pulling away from the wall
  • Floors that feel soft or lift, or wet grout lines on tile
  • Water meter moving with every tap in the house off
  • Sound of running water inside a wall, or a sudden drop in pressure

If you leave it

  1. First hour: water keeps spreading into drywall, cabinets and flooring
  2. 24 to 48 hours: mold can start on wet material (EPA)
  3. A few days: baseboards swell, paint peels, wood floors cup
  4. A week: drywall goes soft and carpet pad stays wet underneath
  5. Weeks: hidden mold in wall cavities, rot in cabinet bases and subfloor
  6. Long term: a small leak becomes a rebuild, and many policies treat long-term seepage differently

Where pipes fail in South Florida homes

Hard freezes are rare here, so a burst here is rarely ice. It is a failed part. The braided hose under a sink or behind a toilet, the washing machine hoses, the dishwasher connection and the thin ice maker line behind the fridge all wear out. When one lets go, it runs at full line pressure until someone shuts the water off. Old copper and galvanized pipe can also pinhole or split at a fitting.

A burst inside a wall, a cabinet or the floor edge is the expensive kind, because nobody sees it. Water runs down the framing, along the bottom plate and under the floor, and you find it by smell or a soft spot. If the wet spot sits in the middle of a concrete floor, that is a different job, and our page on slab leaks covers it.

The first hour, step by step

1. Shut off the main water valve. In most houses it is on the front wall of the house or in the meter box near the street, and in a condo it is often in a utility closet. If you do not know where yours is, find it today and turn it once so it does not seize. 2. If one fixture is the problem, close its stop valve, the small oval handle under the sink or behind the toilet, and leave the main on for the rest of the house. 3. If water is near outlets, a ceiling light or the panel, do not wade in. Turn off that breaker only if you can reach the panel dry. If you cannot, call an electrician.

4. Take photos and video of the source and every wet surface before you move anything. 5. Lift rugs, boxes and electronics off wet floors, and put foil or plastic blocks under furniture legs. 6. Call a plumber to fix the line. Water in the walls cannot dry while the pipe is still leaking. 7. Call us for extraction and drying, any hour. According to the EPA, mold usually does not grow if wet material is dried within 24 to 48 hours, so the first day matters more than the second.

What we do once the pipe is shut off

We extract the standing water with our own equipment. Then we take moisture readings in the drywall, baseboards, cabinets, subfloor and slab to find where the water went. It goes farther than it looks. Our technicians are IICRC-certified, and the readings tell us what to dry in place and what has to come out. The plumber fixes the line, and we do not do plumbing, so we plan our work around that visit.

Then we dry. Air movers and dehumidifiers run until the readings come back to normal, not until the surface feels dry. Insulation, swollen baseboard, soft cabinet bases, wet carpet pad and the lower part of the drywall come out if they will not dry. Once the house is dry we handle the reconstruction too: new drywall, baseboards, flooring, tile, cabinets and paint, and full kitchen and bathroom work when the damage is big. It is one crew from extraction to the final walkthrough.

We photograph each stage and keep the readings, so there is a record of what was wet, what we removed and why.

What can be saved and what usually cannot

Water from a broken supply line starts out clean. If you catch it fast, painted drywall, solid wood and tile often dry in place. Particle board, MDF baseboard, insulation and carpet pad usually do not come back, because they swell and hold water. Pressed-board cabinet bases are the usual loss in a sink leak.

Where the water came from changes the job. The IICRC puts sewage and waste line backflow in Category 3, the most contaminated class, and those jobs are handled differently from a supply line. Washer and dishwasher discharge carries soap and dirt, so restorers treat it with more care than clean supply water. Our page on wet carpet explains the three categories.

What insurance usually looks at

Homeowners policies usually respond to a sudden and accidental release of water, like a burst line. They often treat a slow leak that ran for weeks or months differently, and many pay to open a wall to reach the pipe but not to fix the pipe itself. Your policy wording and your adjuster decide, so read the water damage section and ask.

We take photos, moisture readings and a written scope of the work for your adjuster. We do not file or negotiate the claim. That stays between you and your insurer. In Florida, a property claim is barred unless you give notice within 1 year after the date of loss, so do not wait. Our insurance claim guide walks through the steps.

Common questions

Where is the main water shutoff, and what if it will not turn?

In most Miami-Dade houses the shutoff is on the front wall of the house or in the meter box near the street. In a condo it is often in a utility closet or near the water heater. A round handle means a gate valve. They stick after years of sitting, and forcing one can snap the stem. A lever that turns a quarter turn is a ball valve, and it is far more reliable. If yours will not close, call the water utility or a plumber. The valve at the meter is the utility's, and a plumber can replace yours. Once the water is off, check the meter. The EPA's WaterSense program suggests reading the meter before and after two hours with no water in use. If it still moves, there is a leak between the meter and the valve, or the valve is not sealing.

How fast does mold start after a pipe leak?

The EPA says that if wet or damp material is dried within 24 to 48 hours after a leak or spill, in most cases mold will not grow. After that, the odds turn the other way. That is why the first day matters more than the second, and why we get extraction and drying going as soon as the plumber has the line shut off. Wet drywall, insulation, carpet pad and particle board are the first to go. Mold can grow inside a wall where you cannot see it, so a musty smell after a leak is a reason to look, not to spray air freshener. If we see signs of mold, a mold assessment may be needed before the wall is closed back up, and we will tell you. Fixing the water comes first either way, because mold has nothing to grow on once the material is dry.

Does homeowners insurance cover a burst pipe in Florida?

Often yes for the water damage, but it depends on your policy. Most homeowners policies respond to a sudden and accidental release of water, like a supply line that bursts. Many treat a leak that ran for a long time differently, and many pay to open a wall or floor to reach the pipe but not to repair the pipe itself. Your deductible and any water damage limit in the policy matter too. The Florida Department of Financial Services' Homeowner Claims Bill of Rights tells policyholders to make and document the emergency repairs needed to stop more damage, keep the damaged property if they can, and keep receipts and photos. That is how we work as well. We take photos and moisture readings and write up a scope for your adjuster, and we can keep a sample of what we removed. The coverage decision is between you and your insurer, so read your policy or ask your agent.

Do I have to cut out the drywall after a pipe leak?

Not always. It depends on the readings, not on how the wall looks. Painted drywall that got clean water and was caught early can sometimes be dried in place with air movers and dehumidifiers, with readings taken each day until it matches a dry wall. We cut it out when it is soft, sagging, stained, coming apart at the tape, or still wet after drying, and when there is wet insulation behind it. Insulation that gets wet is almost always removed, because it holds water against the studs. When we cut, we cut in a straight line above the wet line, which is easier to patch and paint than a ragged hole. Drywall that stayed wet for days from a slow leak is usually a tear-out. Do not paint or patch over a wet wall. Paint traps the moisture, and the stain comes back.
