Control water and hazards
The water supply is shut off as needed and electrical or structural risks are addressed.

Burst & Frozen Pipe Response
A suspected frozen or burst pipe requires prompt water control and cautious thawing. Shut off the affected supply or main, open a faucet to relieve pressure, avoid flames and uncontrolled heat, and remember that a split may not leak until the ice begins to thaw.
Warning Signs & Reasons to Schedule Service
- No flow from one fixture during freezing weather.
- Frost, bulging, or unusual condensation on exposed pipe.
- Water stains or sounds inside a wall after temperatures rise.
- A sudden pressure drop or high water use.
- An outdoor, crawlspace, garage, or exterior-wall pipe was exposed to cold.
What the Process Usually Includes
Locate frozen and damaged areas
Accessible piping, insulation, heat, air leaks, and likely concealed routes are assessed.
Thaw or expose carefully
Safe, controlled methods are used, and concealed areas may require access when leakage is suspected.
Repair and prevent recurrence
Damaged piping is repaired, pressure-tested, and freeze-protection improvements are discussed.
Advice for Common Situations
Never use an open flame
It can cause fire, pipe damage, steam pressure, and injury.
Assume more than one split may exist
Long frozen sections can fail at several points.
Keep water off during initial thaw if a break is possible
A hidden split may release significant water as ice melts.
Correct the cold-air path
Insulation alone may not help if outside air reaches the pipe through gaps or vents.
Burst & Frozen Pipe Response FAQs
Can a frozen pipe thaw without bursting?
Yes, but it should still be monitored because damage may be hidden.
Where do frozen pipes commonly occur?
Exterior walls, crawlspaces, garages, hose connections, cabinets, and areas exposed to air leaks are common.
Can heat tape prevent freezing?
Listed products can help in appropriate locations when installed and maintained correctly, but they are not a substitute for correcting major exposure.
Should I leave faucets dripping?
It can reduce risk in some situations, but weatherization, heat, insulation, and shutting down vulnerable seasonal lines are more reliable strategies.
