Burst Pipe Repair

Emergency pipe repair and water damage cleanup

A burst pipe can release hundreds of gallons per hour. Emergency services include water shutoff assistance, pipe repair coordination, water extraction, structural drying, and damage documentation for insurance. Response within 60 minutes is critical.

Quick answer

Burst pipe restoration covers everything after the plumber: extracting the released water, drying the framing and subfloor, and repairing the drywall, flooring and insulation the water reached. Typical cost is $1,200–$8,000 over about four days. Because a burst line can release water for hours before it is found, the damage usually extends well beyond the room where the pipe failed.

Common Causes of Burst Pipe Repair

  • Freezing temperatures
  • Water pressure spikes
  • Pipe age and corrosion
  • Physical damage
  • Soil shifting (slab leaks)

What the Restoration Process Involves

  1. 1Initial assessment: moisture meters, thermal imaging, damage classification under IICRC IICRC S500
  2. 2Water extraction with truck-mounted or portable extraction units
  3. 3Structural drying with industrial air movers and dehumidifiers
  4. 4Antimicrobial treatment of affected surfaces
  5. 5Daily moisture monitoring until IICRC dry standards are met
  6. 6Restoration of damaged structural elements, flooring, and finishes
  7. 7Final documentation package for your insurance claim

Burst Pipe Repair Questions

What should I do immediately when a pipe bursts?
1) Shut off the main water supply immediately — know where your shutoff is before an emergency. 2) Shut off electricity to affected areas if water is near outlets or panels. 3) Call a restoration company — not a plumber first. Restoration teams extract water while plumbers repair the pipe.
How much water can a burst pipe release?
A 1/2-inch supply line under normal household pressure can release 50 gallons per minute. A 3/4-inch line can release 100+ gallons per minute. A 4-hour delay can mean 24,000+ gallons — enough to destroy flooring, drywall, and framing throughout an entire floor.
Does insurance cover a burst pipe?
Yes, most standard homeowners policies cover sudden burst pipes. However, insurers may deny claims if they find evidence the pipe had been leaking gradually (e.g., water stains, corroded fittings). Document fresh damage and have a professional assess pipe condition.
How do I find the source of a slab leak (burst pipe under concrete)?
Slab leaks require specialized detection because the pipe is embedded in or under the concrete slab — not accessible without cutting. Signs of a slab leak: hot spots on the floor, the sound of running water when all fixtures are off, unexplained water bills increases, or wet flooring with no apparent source above. Detection methods used by professionals: pressure testing (isolate sections and check pressure drop), acoustic leak detection (amplified listening for running water in the slab), and electromagnetic pipe locating. Once located, repair options include: spot excavation and pipe repair, epoxy pipe lining, or full repipe (rerouting pipes through the attic instead of the slab).
Can a burst pipe that was quickly stopped still cause mold?
Yes — even a fast response allows significant moisture absorption. In the 5–60 minutes between a pipe bursting and water being shut off, water can penetrate drywall, subfloor, insulation, and wall cavities. These materials retain moisture long after the surface appears dry. Without professional moisture meter verification, homeowners frequently assume the area is dry when hidden moisture is still at 25–30% — sufficient to support mold growth within days. A professional moisture mapping session after any burst pipe (even one caught quickly) confirms whether drying equipment is needed.
