A burst pipe is one of the few plumbing problems that genuinely can't wait. Water actively flowing from a broken supply line causes damage by the minute, and burst pipe repair in Longmont, CO is one of our most common emergency calls, especially during the hard winter freezes this area sees regularly.
Why Longmont Sees Burst Pipes
Longmont's semi-arid climate has recorded winter lows as cold as -38°F, and any exposed or poorly insulated pipe (in a crawlspace, an exterior wall, an unheated garage, or an attic) is at real risk during a hard freeze. Water expands as it freezes, and that expansion is what actually splits the pipe; the burst usually isn't discovered until the ice plug thaws and water starts flowing through the break. This means a pipe can freeze and split days before anyone notices, with the actual flooding showing up once temperatures rise again.
What to Do Immediately
- Shut off the main water valve to the house immediately; this is the single most important step and stops the flooding at its source
- Turn off electricity to any affected area if water is near outlets, switches, or fixtures, if it's safe to reach the breaker without stepping through standing water
- Open a faucet on the lowest level to help drain remaining water from the pipes and relieve pressure
- Move valuables away from the affected area if it's safe to do so
- Call for emergency repair right away; the longer water flows, the more it costs to remediate afterward
Finding and Fixing the Break
Once the water is shut off, the actual repair depends on where the pipe burst and how accessible it is. A break in an exposed section (under a sink, in a visible section of basement plumbing) is straightforward to access and repair. A break inside a wall or in a crawlspace takes more work to locate and access without unnecessary demolition, which is where a controlled, targeted approach to opening the wall or ceiling makes a real difference in how much repair the drywall itself needs afterward.
If the burst happened at a point where the pipe was already compromised (heavy corrosion, an old repair, or aging galvanized pipe common in Longmont's East Side and West Side Historic District homes), that section is usually replaced with modern PVC or PEX rather than patched. The surrounding pipe is likely to fail again soon if it's the same age and material.
Preventing the Next One
Insulating exposed pipes in crawlspaces, attics, and exterior walls before winter, disconnecting and draining outdoor hoses, and keeping a minimal trickle of water running through vulnerable pipes during extreme cold snaps are the standard prevention steps for Longmont's climate. See frozen pipe repair for what to do if a pipe has frozen but hasn't burst yet, since catching it at that stage avoids the water damage entirely. A whole-home repiping conversation is also worth having if a house has already had more than one burst from aging galvanized pipe, rather than treating each burst as its own isolated event.
What Affects the Cost
Location of the break
An exposed, accessible pipe costs less to repair than one inside a wall or hard-to-reach crawlspace.
Pipe material and condition
Aging galvanized pipe is often replaced rather than patched, which is a larger scope than a simple repair.
Time of call
Emergency, after-hours response is priced for the urgency, since a burst pipe can't wait for a standard appointment.
Extent of the break
A single split is a smaller repair than a section of pipe damaged at multiple points by the same freeze.
Access and drywall/demolition needs
A break inside a finished wall may require some opening and later patching, which affects overall project cost beyond the plumbing itself.

Frequently Asked Questions
Shut off the main water valve to the house immediately. This stops the flooding at its source and matters more than anything else in the first few minutes. Everything else, electricity, valuables, calling for repair, comes after that.
A pipe usually splits while frozen, from the ice expanding, but the flooding doesn't show up until the ice thaws and water starts flowing through the break. This delay is normal and is why burst pipes often get discovered once temperatures warm back up.
No, those are separate jobs. Burst pipe repair fixes the pipe itself; water damage to flooring, drywall, or belongings is a separate remediation and restoration process, sometimes handled by a different specialist depending on the extent of the damage.
Homes with original galvanized pipe, common in the East Side and West Side Historic Districts, are more vulnerable since decades of corrosion weaken the pipe wall before a freeze even happens. When a burst occurs at a compromised section like that, it's usually replaced rather than just patched.
Yes, around the clock. A burst pipe is exactly the kind of emergency that shouldn't wait for business hours.
