Prevent Frozen Pipes in Your Missouri Home With These Tips

When winter shows its fury, and temperatures drop into the single digits, most homeowners in Clayton worry about their furnace or heating bills.

At Tony LaMartina Plumbing Company, we know the biggest threat to your comfort and wallet this winter lurks silently between walls and beneath your floorboards: frozen pipes.

A single burst pipe can release more than 250 gallons of water in a day, damaging your foundation, flooring, electrical system, and appliances. However, you can help prevent freezing, thawing, and pipe leaks with inexpensive, effective insulation.

Keeping your plumbing warm so ice doesn’t form keeps your home dry and gives you peace of mind.

As experts in the field, we’ve witnessed flooded basements and ruined heirlooms firsthand. We want to help you avoid that catastrophe with our guide to winterizing your plumbing and what to do if the worst happens. Read on to discover how you can prepare your pipes for winter weather.

Why Pipes Freeze and Burst

You might assume that pipes burst because water inside the plumbing freezes and, as ice, pushes against the walls of the pipe. Extreme water pressure is another reason.

When a plug of ice forms in a pipe, the water between that plug and the closed faucet becomes trapped. As the ice expands, it pushes the liquid water toward the faucet, spiking the water pressure. Eventually, the pipe—whether it’s copper, PVC, or PEX—splits under pressure.

Insulate to Prevent Frozen Pipes

The most effective way to prevent frozen pipes is to keep the air surrounding your plumbing well above 32°F. Any pipe that runs through an unheated area, such as a crawl space, attic, garage, or even an exterior-facing kitchen cabinet, is susceptible to freezing.

The Spruce, an online home improvement platform, notes that pipes technically can freeze at 32°F, but are more likely to freeze at 20°F.

Pipe Insulation Options

• Foam Sleeves are the gold standard for do-it-yourselfers. Made of polyethylene or rubber, they are pre-slit and easy to install on long, straight pipe runs.

• Fiberglass Pipe Wrap is best for tight corners, valves, or areas where pipes are clustered together. It’s essentially a ”blanket” roll for your plumbing.

• Self-Sealing Foam has an adhesive strip attached.

• Electric Heat Cables plug into an outlet and use a thermostat to apply heat directly to the pipe when the temperature drops. They can also be hardwired into the electrical system. We suggest a licensed electrician install your cables. A professional can ensure the wiring and grounding are correct, minimize safety risks, and meet local code requirements.

How to Insulate Your Pipes

To insulate plumbing, start by identifying every foot of pipe in unheated areas, including pipes under sinks near exterior walls. Wipe away any condensation or dust, and then slide the foam sleeves onto the pipes. 

Don’t leave any gaps between sections. Even a half-inch of exposed pipe can hasten freezing. Use duct tape or high-quality zip ties every 12 inches to prevent the sleeve from sagging or pulling apart over time.

Finally, check the area where pipes enter the walls. If you see light or feel a draft, use expandable spray foam or caulk to seal the hole. A cold draft blowing directly on a pipe helps to quickly freeze it.

In an Emergency, Find Your Water Shut-Off

If you turn on your faucet and only a trickle comes out—or worse, you see water pooling on the floor—you have an emergency on your hands. You must stop the flow of water immediately. To do that, every member of your household needs to know where the main shut-off valve is and how to shut it off.

In most homes, the main valve is typically located near the water meter, often in a basement,  utility closet, or crawl space near the front of the house.

If you see a straight lever, that’s a ball valve. Parallel to the pipe means “open.” Turning it 90 degrees (perpendicular) means “closed.” If your valve looks like a circular wheel or a spigot handle, turn it clockwise until it stops.

You can usually turn most valves by hand, but you may need a wrench if the valve hasn’t been used for years and is stuck in place.

In some cases, your indoor shut-off might fail. You may need a “curb key” to reach the valve located in the underground meter box in your yard.

Professional Inspections & 24/7 Support in University City. MO

Some risks are invisible to the naked eye. A small, hairline leak behind a wall can turn into a massive burst when the water inside it freezes. Unseen issues are a top priority during our licensed plumbers’ annual plumbing inspection.

During a winterization visit, we look for things homeowners often miss:

• Corroded Fittings: These weak spots are likely to fail under the pressure of a freeze.
• Improper Grading: Sagging pipes allow water to pool and freeze more easily.
• Outdoor Spigots: We check your “frost-free” hose bibs and ensure your garden hoses are disconnected.

Even with perfect preparation, extreme winter weather can be unpredictable. If a pipe bursts at 2 a.m. on a weekend, you shouldn’t have to wait until Monday morning for help. Our team provides 24/7 emergency plumbing services to prevent further damage and restore your home to its original condition. We don’t just patch a pipe; we analyze why it failed so it doesn’t happen again.
