How to Prevent Frozen Pipes in Columbus This Winter

Of all the plumbing emergencies a Columbus homeowner can face, a frozen pipe is among the most preventable — and among the most destructive when it is not prevented. When water freezes inside a pipe, it expands with enough force to split copper, PVC, and even cast iron, and the resulting burst often does not reveal itself until the pipe thaws and floods your home. The good news is that a little preparation before and during cold snaps dramatically lowers your risk. Here is a practical winter checklist built for Central Ohio's climate.

If a pipe is already frozen, do not wait for it to burst — see our guide on what to do, and call our 24/7 line at (614) 420-2672.

Why Columbus Pipes Freeze

Central Ohio routinely drops below freezing from December through March, and polar-vortex cold snaps push temperatures far lower. Pipes do not all freeze equally: the ones at risk run through unconditioned or poorly insulated spaces — exterior walls, crawl spaces, attics, attached garages, and unheated basements. During a hard freeze, more than one pipe can freeze in a single home at once, which is why prevention beats reaction every time.

Before Winter: Set Yourself Up

Tackle these once, ideally in the fall:

• Insulate vulnerable pipe runs. Add foam pipe insulation to any exposed pipes in crawl spaces, basements, garages, and exterior walls. For runs that freeze every year, heat cable (electric pipe heating tape) adds an extra layer of protection.
• Seal drafts near pipes. Cold air pouring through a gap in the rim joist or an unsealed crawl-space vent can freeze a pipe even when the house feels warm. Seal gaps and close foundation vents for the season.
• Disconnect and drain outdoor hoses. Remove garden hoses, shut off and drain exterior hose bibs, and install faucet covers. A hose left attached can freeze and back the ice up into the wall.
• Know where your main shutoff is. If a pipe does burst, shutting off the water fast is the single most important thing you can do. Find your valve now — our guide on how to shut off your water main walks you through it.

During a Cold Snap: Daily Habits

When the forecast calls for a hard freeze, layer on these habits:

• Let faucets drip. A slow trickle from faucets served by vulnerable pipes relieves pressure and keeps water moving, which makes freezing far less likely. Prioritize taps on exterior walls.
• Open cabinet doors. Under sinks on exterior walls, open the cabinet doors so household heat can reach the pipes behind them.
• Keep the heat on — even when away. Never let the thermostat drop below about 55°F, even when you travel. A warm house is your cheapest freeze insurance.
• Keep the garage closed. If water supply lines run through an attached garage, keep the garage door shut to hold in what warmth there is.

If You Travel in Winter

An empty house during a cold snap is a classic recipe for a burst pipe discovered days later. Before you leave, set the thermostat no lower than 55°F, consider shutting off the main water supply and draining the lines, and ask a neighbor to check the house. For homeowners who travel often, a whole-house automatic water shutoff device can cut the water automatically the moment it detects a leak — stopping a burst before it floods an empty home.

Spotting a Freeze Before It Bursts

Even with precautions, catch problems early. The first sign of a frozen pipe is usually no water from a faucet, especially one on an exterior wall or in an unheated space. You may also see frost on an exposed pipe or hear a hollow sound when you tap it. If one faucet stops during a cold snap, check them all — multiple freezes in one event are common.

The One Thing You Must Never Do

If you find a frozen pipe, never use an open flame — a propane torch or similar — to thaw it. Open flame causes house fires and steam burns across Ohio every winter. Instead, shut off the main as a precaution, open the affected faucet so water and steam can escape as it thaws, and call a professional who uses safe electric thawing equipment. Our frozen pipe repair service explains the safe approach in detail.

Put It All Together

Frozen pipes are not bad luck — they are the predictable result of unprotected pipes meeting Ohio cold. Insulate the vulnerable runs, build the cold-snap habits, know your shutoff, and you will sail through winter without the 2 a.m. flood.
