How to Prevent Frozen & Burst Pipes During Connecticut’s Late Winter Cold Snaps

March may feel like the start of spring, but in Connecticut, winter isn’t done with us just yet. Every year, homeowners face surprise overnight freezes that put plumbing systems at serious risk. At Mansolf Plumbing & Heating, we handle a spike in calls this time of year from frozen pipes, cracked lines, and urgent burst pipe repair needs across Connecticut.

Late‑season cold snaps can be especially damaging because homeowners often let their guard down, thinking the worst of winter has passed. Below, we’ll explain why pipes still freeze in March, how to prevent costly damage, and what to do if you detect a problem.

Why Pipes Still Freeze in March

Even when daytime temperatures feel mild, nighttime lows can drop well below freezing. This freeze‑thaw cycle creates ideal conditions for pipe problems, especially in uninsulated or exposed areas such as:

  • Basements and crawl spaces
  • Garages and workshops
  • Attics and under‑insulated walls
  • Outdoor hose lines and sillcocks

When water freezes, it expands—putting extreme pressure on the pipe walls. Once temperatures rise again, the ice melts and water escapes through any cracks or ruptures, often causing extensive property damage.

Tips to Prevent Frozen & Burst Pipes During Late‑Winter Cold Snaps

1. Keep Interior Temperatures Consistent

Don’t dial your heat down too far at night. Even if you're trying to save energy, the cost of a burst pipe far outweighs a slightly higher heating bill.

2. Open Cabinet Doors

Allow warm air to circulate around plumbing under sinks—especially on exterior walls.

3. Drip Your Faucets Overnight

Running water helps prevent freezing. A slow drip in the coldest rooms can keep your pipes safe during overnight freezes.

4. Insulate Exposed Pipes

Use foam insulation sleeves or heat tape to protect vulnerable pipes in basements, garages, and crawl spaces.

5. Disconnect Outdoor Hoses

Even in March, leaving hoses attached can trap water and cause outdoor faucets—or the connected interior pipes—to freeze.

6. Seal Drafts and Air Leaks

Cold air sneaking into basements or crawl spaces can quickly freeze pipes. Use caulk or insulation to seal gaps around windows, doors, and foundation openings.

Signs Your Pipes May Be Freezing

  • Little or no water flow from faucets
  • Unusual gurgling or banging sounds
  • Frost visible on exposed pipes
  • Sudden drops in water pressure

If you notice any of these warning signs, act fast and call an emergency plumber in CT to prevent major damage.
