Frozen and Burst Pipe Damage: what it covers

Quick answer

Frozen and burst pipe damage is water released when a pipe in a cold cellar, exterior wall or garage freezes, splits and then leaks as it thaws. Buffalo Water Damage Restoration answers calls around the clock, sends a crew as soon as one is free, and dries the wall and floor where the water went.

A pipe does most of its damage when it thaws. Water that freezes expands and can split a pipe without any sign of a leak, and the split only shows when the ice melts and the water starts moving again. Pipes in unheated cellars, crawl spaces, exterior walls and garages are most exposed, because they sit where the cold reaches them first.

Buffalo winters bring heavy lake-effect snow, and the National Weather Service Buffalo office keeps the history of those storms. Cold weather is what freezes pipes in unheated spaces, and a freeze that follows a heavy snowfall is one of the conditions in which pipes split. A pipe that froze in one cold week may leak only when the thaw starts, days later.

A leak from a frozen pipe can run for hours before anyone sees it, because the water travels inside the wall and along the joists. Call (833) 490-5225 as soon as water is seen, and shut the main at the house if you can reach it. A crew is sent as soon as one is free to extract the water and look for the wet materials that the leak reached.

Warning signs

Signs you need frozen and burst pipe damage

Do not work on a pipe while water is still flowing, and do not use a torch or a heat gun on a frozen pipe near wood framing or insulation, because that can start a fire. Keep the power off to any wet area, and do not step into standing water near a light or an appliance. Gas equipment that was in water should be checked before use. If the main valve is stiff, do not force it, and call for help instead.

  • No water flowing from a tap during a cold spell, or a tap that runs weakly or not at all
  • A bulge or a crack in a pipe visible in an unheated cellar or garage after a freeze
  • Water dripping from a ceiling or a wall after the temperature rises
  • A damp patch on a wall or floor near a pipe that runs along an exterior wall
  • A sudden drop in water pressure after a thaw
  • Frost on the outside of a pipe, a window or a wall where a pipe is hidden inside
Our process

How our frozen and burst pipe damage visit works

  1. Shut off the water at the main

    Closing the main stops the flow into the building, so the leak does not keep running while the crew is on its way. The valve is usually in the cellar near where the service enters, and it should be turned off by hand, with care, before anyone works on the pipe.

  2. Make the space safe and check for power

    Water near a light, outlet or a water heater is a shock hazard, so the power to the affected area is switched off. The crew checks the cellar or the garage for any gas equipment that has been wet before it approaches.

  3. Extract and locate the wet area

    Standing water is pumped out and the wet area is traced from the leak point. Moisture readings in the wall and floor show how far the water has traveled, which is often farther than the stain shows.

  4. Open the wall or floor where the water went

    Where the water is inside a wall or under a floor, the finish is opened at the points the readings show. The openings are kept small and placed so the crew can reach the wet materials and the pipe.

  5. Dry the structure and hand over the repair

    The cavities, framing and subfloor are dried until the readings show a dry level. A plumber repairs the split pipe on a separate visit, and the crew's note records the leak point, the readings and the openings made.

Job stories

Typical jobs for frozen and burst pipe damage

Typical job

A supply line splits inside an outside wall in a cold snap

What homeowners notice
After a cold week the owner notices a damp patch on a ground-floor wall and a faint sound of running water inside it. The supply line runs along an outside wall in an enclosed porch and had frozen before the thaw started.
What we do
The owner is asked to close the main, which is done before the crew arrives. The crew reads the wall in a grid, finds the highest readings low on the wall and opens a small section there. The split is recorded for the plumber, and the wet insulation and plate are removed where they cannot be dried in place.
What to expect
The plumber repairs the line on a separate visit. The wall is dried to its readings, the opening is kept for the plumber's inspection, and the owner has the note that names the split and the municipality it was in.

Why do pipes burst when the weather warms up?

Water expands when it freezes, and a pipe can split while it is still frozen. The split leaks only when the ice melts and the water flows again, so the leak often appears days after the cold snap.

A pipe that freezes can stay sealed by its ice plug for a while, so no water flows and no leak shows. When the thaw comes, the ice melts from the outside in, and the water inside begins to move through the split. The first sign is often a wet spot on the floor or a ceiling stain several rooms away from the pipe.

The pipes most at risk sit where the cold reaches them first: along exterior walls, in cellars with little heat, in crawl spaces and in garages. A cold spell can keep those spaces below freezing for days, so the risk is highest during a cold spell.

What should I do first when a pipe bursts?

Shut off the water at the main, turn off power to the wet area, and keep people away from standing water. Then call for a crew, and photograph the damage before anything is moved.

The most important step is closing the water at the main. Find the main valve, which in older houses is often in the cellar near the meter or where the service pipe enters, and turn it off by hand. If the valve is stiff or you cannot find it, close the nearest fixture valve and call for help, because the leak will continue until the supply is stopped.

Once the water is off, photograph the wet areas and the water line. Turn off the electricity to any room that has water in it, and move valuables to a dry spot. Call (833) 490-5225 and say where the pipe is, what you can see and whether the main has been closed.

  • Close the main valve by hand, carefully, if you can find it
  • Turn off the breaker to any wet room or cellar
  • Keep people and pets out of standing water
  • Photograph the leak, the water line and any damaged materials
  • Report the location of the pipe and whether the main is closed

How does a crew find a leak inside a wall?

The crew reads moisture levels in the wall and floor, follows the water's path from the stain and the readings, and opens the finish only where the readings show the leak is. Opening the wall at the wrong place wastes time and material.

Water inside a wall can travel up, down and sideways along the studs, the plates and the joists before it shows on the finish. The crew takes readings in a grid across the wall and the floor and notes the highest points. The water's path is traced from there back to the probable leak, and the finish is opened at the points that matter.

The openings are made small and placed for access, so the plumber can reach the pipe and the crew can reach the wet materials. Each opening is photographed and recorded, so the repair can be planned and the openings can be closed afterward.

Can a frozen pipe be prevented from bursting?

Keeping pipes warm, sealing the openings where cold air gets in and letting taps run during a hard freeze reduce the risk. These steps are general advice, and a plumber can advise on the pipes in a particular house.

In cold weather, pipes in unheated spaces benefit from insulation, from sealed openings where cold air enters the cellar or the wall, and from heat kept at a steady level in the house. Letting a tap run slowly during a hard freeze can keep the water moving, which helps prevent a freeze, but it does not fix a pipe that is already split.

The general advice on preventing freezes is not a guarantee. A plumber or a qualified heating technician can look at the pipes in a particular house, and that visit is a better guide than a general rule. A crew working on water damage cannot assess the pipes for freeze risk, and it says so when a homeowner asks.

What moves the cost of a frozen or burst pipe job?

How long the leak ran, how far the water traveled, how many walls and floors were reached, and how much finish had to be opened all change the work. The price is explained and approved on site before any equipment is set up.

A pipe that leaked for a short time inside one wall is a smaller job than one that ran for hours through several floors. The number of rooms, the amount of insulation and framing that is wet, and the finishes that must be opened are the main factors in the scope.

Repairing the pipe is a plumbing job and is priced separately by the plumber. The drying crew explains what it has dried and what remains, and it confirms the price for its own work on site before any equipment runs.

Options

Types and options for frozen and burst pipe damage

Split pipe in a cold cellar

A supply line in an unheated cellar often splits near the wall, the meter or a joint. The water runs down the foundation wall and across the floor, so the crew extracts the cellar and checks the wall plate and the joists above it.

Leak in an exterior wall or porch

A pipe that runs along an outside wall or inside an enclosed porch can freeze and split inside the wall. The water runs down through the framing and can reach the rooms below. The crew opens the wall where the readings are highest and checks each floor the leak reached.

Burst line in a garage or outbuilding

A garage or an outbuilding with a water line can flood the slab and the walls, and the water may run under a shared wall into the house. The crew checks the slab, the wall and the connection to the house before it decides on the scope.

Failed water heater or fitting after a freeze

A water heater or a fitting that froze can split at a joint or a valve. The crew treats it as a leak source, shuts the supply and checks the area around the heater, then notes the repair needed.

Erie County

Why frozen and burst pipe damage is different in Western New York

Buffalo's pipes face a cold that comes in waves. The National Weather Service Buffalo office records heavy lake-effect snowfalls, including the 20.1 inches logged at the Buffalo Airport over about 24 hours in December 1979. Cold weather is the time when unheated cellars and garages are most likely to freeze.

Cellars, garages and enclosed porches are where pipes near outside walls are most exposed to cold. The crew checks those spaces first when it arrives, because they are where a split pipe is most likely to be hidden.

Pipes can run through open cellars, wall cavities or insulated walls. The crew adjusts the search for the leak to whatever wall or floor it finds, rather than assuming the pipe runs where the plan shows it.

One call and it gets handled.

A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

FAQ

Frozen and Burst Pipe Damage FAQs

What should I do if the pipe is frozen but not yet burst?

Do not open the tap as a test. Keep the space warm if you can do so safely, and let a plumber thaw the pipe. Using an open flame or a heat gun on a pipe near framing or insulation is a fire risk.

Where is the main shut-off in a Buffalo house?

In older houses it is often in the cellar, near where the service pipe enters the building or near the meter. In newer houses it may be in a utility area. If you cannot find it, call the crew and ask for help locating it.

Will the crew find the split pipe?

The crew traces the water and reads the moisture in the wall and floor to find the likely leak point. The split itself is repaired by a plumber, who may need to open the wall at a point the crew suggests.

Does a frozen pipe always burst?

No. Many frozen pipes do not split, but some do, and the split often shows only at the thaw. A plumber can check a frozen line, and a crew can dry any water that has already leaked.

How long after a freeze can a pipe leak?

A leak can appear during the cold, at the thaw, or days later, because the split only leaks once the water flows again. Keep watch on the cellar and the walls after any cold spell, and call if a stain or a damp patch appears.

Does insurance cover a burst pipe?

That depends on the policy, the cause of the loss and any freeze exclusions, and the insurer decides. Keep the photographs, the readings and the crew's records, and ask the insurer what it needs for the claim.

Who repairs the pipe after the drying?

A plumber repairs the pipe. The drying crew does not repair plumbing, and its note records the leak point and the openings made, so the plumber can start from the right place.
