Plumbing

As temperatures plunge across Central Ohio this winter, one of the most common—and devastating—home emergencies we see at Dor-Mar is frozen pipes. What starts as a minor inconvenience can quickly turn into a major disaster: pipes freeze, expand, and burst, flooding your home with hundreds of gallons of water per hour.

The average cost of water damage from a burst pipe? $5,000 to $15,000 or more, according to insurance industry data—not to mention the hassle of repairs during the coldest time of year.

The good news: most frozen pipe emergencies are entirely preventable with a few simple steps. In this guide, we’ll walk you through the risks, proven prevention tips, and what to do if disaster strikes. Plus, learn how Dor-Mar can help with professional pipe insulation and 24/7 emergency response.

Don’t let Old Man Winter catch you off guard—prepare your plumbing now!

Understanding the Danger: Why Pipes Freeze and Burst

Water expands by about 9% when it freezes. In a closed pipe, that expansion creates tremendous pressure—up to 2,000 psi—enough to crack copper, PEX, or even steel.

Most Vulnerable Areas in Your Home

  • Pipes in unheated spaces: basements, attics, crawl spaces, garages
  • Exterior walls and cabinets under sinks
  • Pipes near drafty windows or doors
  • Outdoor hose bibs and sprinkler lines

In Central Ohio, pipes typically start freezing when outdoor temperatures drop below 20°F for several hours, especially with wind chill.

Proven Tips to Prevent Frozen Pipes This Winter

Take these steps now—before the deep freeze hits—and dramatically reduce your risk.

1. Insulate Exposed Pipes

The single most effective prevention measure.

DIY Options

  • Foam pipe sleeves (available at any hardware store for $1–$3 per foot)
  • Heat tape or cables (electric heating wraps—use UL-listed products)
  • Fiberglass or newspaper wrapping in a pinch

Professional Solution

Dor-Mar offers expert pipe insulation services using high-quality closed-cell foam that provides superior R-value and moisture resistance. We identify every vulnerable pipe and insulate them properly—often completing a whole-house job in a single visit.

2. Maintain Consistent Indoor Heat

Never let your home drop below 55°F, even when away.

  • Set your thermostat no lower than 55°F during vacations
  • Use a smart thermostat to monitor remotely
  • Consider a freeze alarm that texts you if temperatures drop too low

3. Let Faucets Drip During Extreme Cold

A slow trickle relieves pressure buildup.

  • Focus on faucets on exterior walls
  • Both hot and cold lines should drip slightly
  • Collect the water in a bucket to avoid waste

4. Keep Cabinet Doors Open

Allow warmer room air to circulate around pipes under sinks.

  • Especially in kitchens and bathrooms on outside walls
  • Remove harmful cleaners so pets/children stay safe

5. Seal Drafts and Gaps

Cold air sneaking in accelerates freezing.

  • Caulk cracks around windows, doors, and where pipes enter the home
  • Weatherstrip doors and add door sweeps
  • Close foundation vents in crawl spaces

6. Disconnect and Drain Outdoor Lines

  • Shut off outdoor water valves (usually in basement)
  • Drain and remove garden hoses
  • Cover outdoor faucets with insulated covers

7. Prepare for Vacations or Extended Absences

  • Have a neighbor check daily
  • Shut off main water valve and drain the system if leaving for weeks
  • Leave heat on and cabinets open

What to Do If Pipes Freeze (Before They Burst)

Act quickly—time is critical.

  1. Signs of Frozen Pipes
    • No water or reduced flow from faucets
    • Frost on exposed pipes
    • Strange bulging or noises in walls
  2. Immediate Steps
    • Turn on affected faucets to allow melting water to escape
    • Apply gentle heat: space heater, hair dryer, or hot towels (never open flame!)
    • Start from the faucet end and work toward the frozen section
    • Keep cabinet doors open
  3. When to Call DorMar Immediately
    • You hear cracking or see bulging pipes (burst imminent)
    • Water starts flowing suddenly (possible break upstream)
    • You can’t locate or access the frozen section

Our 24/7 emergency plumbers respond fast with specialized thawing equipment to minimize damage.
