What to do first when a pipe bursts
Shut off the main water valve immediately. In most Chesterfield homes with basements, it's on the foundation wall where the water line comes in. Then keep clear of water near electrical outlets and fixtures, open a faucet on the lowest level to drain the lines, and call a plumber to repair the pipe and a restoration provider to deal with the water.
Two jobs: fixing the pipe and fixing the damage
A burst pipe usually needs two different professionals:
- A plumber finds the break, cuts out the damaged section and replaces it.
- A water damage restoration provider removes water from floors, walls and ceilings, dries the structure, and handles material removal and repairs.
Some restoration companies coordinate the plumbing repair too. Ask when you're connected. Restoration is the part that prevents lasting damage, because water from a supply line spreads fast and soaks into materials you can't see.
Why pipes burst in Chesterfield homes
St. Louis winters bring hard freezes. When water freezes in a pipe, pressure builds between the ice and a closed faucet, and the pipe splits. The leak often only shows up when the ice thaws. Pipes most at risk run through:
- exterior walls, especially behind kitchen and bathroom sinks
- crawlspaces, unheated garages and basement rim joists
- attics and additions with poor insulation
- outdoor spigots that weren't shut off and drained before winter
Not every burst is freeze-related. Corrosion, high water pressure and failing appliance supply lines also cause sudden leaks.
Where burst pipe water ends up
Supply lines are under constant pressure, so a split pipe can release a lot of water before it's shut off. That water travels: down through ceilings, inside wall cavities, under flooring and into the basement. A ceiling stain below a bathroom, a soft spot in a floor or water appearing in the basement may all trace back to one break. Restoration starts with removing the water and continues with drying the structure, guided by moisture readings.
Clean water, but not for long
Water from a supply pipe starts out clean (Category 1). If it sits on building materials, it picks up contaminants and can degrade into a dirtier category, which means more cleaning and more material removal. That's one of the main reasons to start restoration quickly. More on this in our post about water damage categories.
Insurance for burst pipes
Homeowners policies commonly cover sudden and accidental water damage from a burst pipe. The National Association of Insurance Commissioners notes that damage from a frozen pipe may not be covered if the insurer finds you didn't take reasonable steps to prevent freezing, such as keeping the home heated. Photograph everything and report the claim promptly. If you need water damage help in Chesterfield after a burst pipe, call and we'll connect you with a local provider.
