October in Mammoth Lakes signals one thing: winter is coming. With chilly mornings, golden aspens, and the first hints of snow, now is the ideal time for homeowners to prepare their properties for the colder months ahead. Whether you live here full-time or own a vacation home, taking care of seasonal maintenance in October can save you from costly repairs, improve energy efficiency, and keep your home cozy all winter long.
Here’s your comprehensive October home maintenance checklist — tailored for Mammoth’s mountain climate.
When winter hits, your furnace or boiler will be working overtime. Avoid mid-season breakdowns by having it inspected early.
What to do:
Schedule a professional HVAC tune-up to ensure efficiency and safety.
Replace or clean air filters for better airflow.
Test your thermostat and consider upgrading to a smart thermostat for remote temperature control — especially useful for second-home owners.
💡 Pro Tip: Keep extra filters on hand so you can change them monthly during heavy use.
Mammoth’s cold mountain air can sneak in through even the smallest gaps, wasting heat and raising energy costs.
Maintenance tips:
Apply weatherstripping to doors and windows.
Use caulk to seal gaps around vents, pipes, and trim.
Inspect attic and crawl space insulation — add more if needed.
Keeping your home well-insulated ensures maximum comfort and helps reduce heating expenses throughout the season.
Fall leaves are beautiful — until they clog your gutters. Clogged drainage can lead to ice dams, roof damage, and leaks once the snow begins to melt.
Checklist:
Clear out leaves, pine needles, and debris.
Flush gutters with water to ensure smooth flow.
Install gutter guards for extra protection before winter storms hit.
Heavy snow accumulation is common in Mammoth, so your roof and chimney need to be in top shape.
Roof checks:
Look for missing shingles, damaged flashing, or weak spots.
Schedule repairs before snow builds up.
Clean and inspect your chimney if you use a wood-burning stove or fireplace.
Not only will this improve safety, but it will also enhance your home’s energy efficiency and prevent leaks during snowmelt.
Frozen pipes can lead to major damage and costly repairs — a risk every Mammoth homeowner should take seriously.
To-do list:
Insulate exposed pipes in basements, crawl spaces, and garages.
Drain outdoor hoses and shut off exterior faucets.
Keep interior temperatures above 55°F if your home will be vacant.
🏡 Tip for Second-Home Owners: Install a smart leak detector that alerts you remotely if freezing or water damage occurs.
Your home’s exterior deserves just as much attention as the inside. Before winter sets in:
Store patio furniture, cushions, and garden décor.
Trim back overgrown branches near your home or roofline.
Drain and winterize sprinkler systems.
Stock up on snow-melt salt, shovels, or a snow blower.
Creating a clear, safe outdoor environment now will save time and hassle when the snow piles up.
Safety should never take a back seat — especially in winter, when fireplaces and heating systems are running daily.
Check and replace batteries in:
Smoke detectors
Carbon monoxide detectors
Smart home sensors or alarm systems
Also, make sure you have a fully stocked emergency kit with flashlights, blankets, and backup batteries.
With shorter days and longer nights, lighting becomes more important.
Replace burnt-out bulbs with energy-efficient LEDs.
Install motion sensor lights for outdoor safety.
Consider energy-saving timers for vacant homes.
You’ll not only save on energy costs but also make your property more secure during the darker months.
A little preparation goes a long way when it comes to maintaining your Mammoth Lakes home. By tackling these October maintenance tasks, you’ll safeguard your property, improve comfort, and be ready to enjoy the upcoming snow season worry-free.
