Winter in Mammoth Lakes brings breathtaking mountain beauty — but it also brings freezing temperatures that can wreak havoc on your home’s plumbing system. For many homeowners, frozen or burst pipes are one of the most common (and costly) winter issues in the Sierra.
Whether you live in Mammoth year-round or own a vacation property, taking a few proactive steps before temperatures plummet can help you avoid major headaches and expensive repairs. Here’s your go-to guide to preventing frozen pipes this winter.
Not all pipes are created equal when it comes to freezing. Focus your attention on the ones most exposed to cold air:
Pipes located in unheated areas such as crawl spaces, attics, garages, and basements.
Outdoor water lines, hose bibs, and sprinkler systems.
Pipes running along exterior walls or near vents and windows.
Once you’ve identified these vulnerable spots, you can start taking targeted measures to protect them before the first deep freeze.
Insulation is your first line of defense against freezing. Use foam pipe sleeves, fiberglass insulation, or even heat tape to wrap exposed pipes in cold zones.
Additionally:
Seal gaps and cracks near windows, doors, and foundation openings where cold air can enter.
Use caulk or expanding foam to close holes around plumbing penetrations.
Add insulation to attics, crawl spaces, and basements to stabilize temperatures.
💡 Pro Tip: Even small drafts can drop temperatures enough to freeze a pipe. A few minutes of sealing can prevent thousands in water damage.
Outdoor plumbing is especially susceptible to freezing in Mammoth’s high-altitude climate. To protect these systems:
Disconnect garden hoses and drain them completely.
Shut off outdoor faucets using interior shutoff valves (if available).
Drain sprinkler systems and blow out the lines to remove any remaining water.
By clearing water from these systems, you eliminate the risk of expansion and cracking when ice forms.
It might be tempting to turn the heat down when you’re away, but maintaining a steady temperature is crucial to keeping pipes safe.
Keep your thermostat set to at least 55°F (13°C) — even if the home is vacant.
Open interior doors and cabinets under sinks to promote warm air circulation.
Close garage doors and ensure all vents are unobstructed for better airflow.
If you own a second home or vacation property, consider installing a smart thermostat so you can monitor and adjust your home’s temperature remotely.
When temperatures drop into single digits, allowing a small trickle of water to flow through faucets can relieve pressure inside your pipes. Running water is less likely to freeze, and this simple step can prevent pipe bursts in especially cold spots.
Focus on faucets connected to exposed pipes or those along exterior walls for maximum protection.
Winter storms in Mammoth can cause temporary power losses — meaning no heat for several hours or even days. To prepare:
Install a backup generator or portable power source for heating systems.
Have extra insulation blankets or pipe covers on hand.
Keep interior doors closed to conserve heat in key areas.
A little preparation ensures your pipes stay protected even if the heat temporarily goes out.
If your Mammoth property will remain vacant during the winter, it’s worth hiring a professional to winterize your home. They can:
Drain water lines and shut off the main supply.
Add non-toxic antifreeze to plumbing traps.
Inspect your system for leaks or weak spots before the freeze.
Partnering with a local Mammoth Lakes property management or maintenance service ensures your home is checked regularly and remains safe throughout the season.
