The first deep freeze on Lake Winnipesaukee can arrive faster than you think. A single burst pipe, an ice-damaged dock, or a weeklong power outage can turn into a costly surprise. Whether you live in Wolfeboro year‑round or close your cottage for the season, a clear, local winterization plan protects your investment and your peace of mind. In this guide, you’ll get a step‑by‑step checklist, a simple timeline, and Wolfeboro‑specific tips so you can head into winter with confidence. Let’s dive in.
Why winterizing matters in Wolfeboro
Wolfeboro winters bring long stretches of subfreezing temperatures, significant snowfall, and frequent freeze–thaw cycles. Lakeside homes face unique risks like frozen plumbing, ice dams, heavy snow loads, shoreline ice movement, and winter storm power outages. Seasonal homes are especially vulnerable when vacant because problems can go unnoticed.
Older camp‑style cottages often have exposed plumbing and minimal insulation, while modern lake homes still need attention to docks, septic systems, wells, and fuel tanks. Planning ahead and following local guidance helps you avoid emergencies and preserve long‑term value.
Your step‑by‑step timeline
6 to 8 weeks before freeze
- Schedule HVAC service and a chimney or flue cleaning. Inspect the water heater and insulate if appropriate.
- Have your septic system inspected. Pump if it is due or if you will leave the home vacant.
- Inspect the roof, flashing, and gutters. Repair damaged shingles and clear debris.
- Trim hazardous limbs near the home, driveways, and overhead lines.
- Line up winter services early: driveway plowing, roof clearing, caretaker checks.
- If seasonal, plan dock and boat removal and confirm timelines with the Town or your marina.
2 to 4 weeks before freeze
- Insulate exposed interior pipes and rim joists. Wrap hose bibs and use frost‑free spigots where possible.
- Test or install heat tape on vulnerable pipes if recommended by a licensed electrician.
- Install or program a smart thermostat with low‑temperature alerts.
- Blow out and drain lawn irrigation and any exterior backflow devices.
- Secure outdoor furniture, hoses, grills, and flammable liquids. Store them safely.
- Check fuel levels and set up automatic deliveries for oil or propane.
Final steps before vacancy or first sustained freeze
If you will leave the home vacant
- Shut off the main water supply. Drain the plumbing system, including water heater, per professional guidance. Open faucets, drain lines, and follow best practices for toilets and traps.
- Turn off water supply lines to appliances and drain them.
- Unplug non‑essential appliances. Clean out the refrigerator and freezer if you will turn them off.
- Close and lock windows and doors. Install storm shutters if available.
- Set the thermostat to a minimum safe temperature. Many contractors commonly recommend 50 to 55 degrees, but confirm with your HVAC pro and insurer.
- Arrange for a local caretaker or service to check the property regularly.
- Secure the garage and shed. Store gasoline and equipment safely.
- Notify your insurance carrier of the vacancy if required by your policy.
If you will occupy the home year‑round
- Maintain a consistent indoor temperature to prevent frozen pipes. Open cabinet doors under sinks on exterior walls during cold snaps.
- Monitor for ice dams after heavy snow. Keep gutters clear.
- Keep plenty of heating fuel on hand and have a backup delivery plan for storms.
Lakefront essentials: docks, boats, shoreline
- Docks and moorings. Ice can shift and damage shoreline structures. Confirm removal windows, storage rules, and winter use policies with the Town of Wolfeboro. Schedule removal before lake ice forms.
- Boats and lifts. Winterize engines, stabilize fuel, drain bilges, and remove or protect batteries. Follow manufacturer instructions for hoists and hydraulic systems.
- Shoreline items. Remove portable furniture, ladders, and water toys. Secure anything that wind, snow, or ice could carry off.
- Shoreline work. If you plan dock or shore repairs, review environmental rules and permitting with the New Hampshire Department of Environmental Services.
Plumbing, water, and septic
- Main shutoff and drains. Locate and label the main water shutoff. For vacant homes, fully drain the system and water heater following professional guidance. Some tasks are DIY, but complete winterization is best handled by a licensed plumber.
- Pipe protection. Insulate exposed pipes in crawlspaces and utility rooms. Use heat tape or cable only where appropriate, installed to code by a licensed electrician.
- Wells. Protect above‑ground well components from freezing without blocking required vents. Review well protection tips through NHDES resources.
- Septic systems. Insulate exposed components, avoid driving over the drainfield, and pump before a long vacancy if a professional recommends it. For current septic guidance, start with NHDES.
Heat, power, and monitoring
- Heating systems. Service your furnace or boiler, confirm safe venting, and protect condensate lines.
- Fuel supply. Confirm automatic delivery and keep tank areas visible to plow crews. Shield above‑ground tanks from drifting snow and vehicle damage.
- Backup power. Consider a standby generator for outages. Operate all generators outdoors and follow code and safety rules. For winter safety and storm readiness, review National Weather Service winter guidance and general alerts at weather.gov.
- Thermostats. For vacant homes kept heated, many contractors recommend setting 50 to 55 degrees to reduce freeze risk. Confirm with your HVAC pro and insurer.
- Remote monitoring. Install smart thermostats, leak detectors, and power monitors. Make sure a local contact can respond to alerts.
Roof, snow loads, and ice dams
- Insulation and air sealing. Add attic insulation and seal gaps around penetrations to help prevent ice dams. Keep attic ventilation balanced.
- Roof checks. Repair weak spots and flashing before winter. Plan safe snow removal when accumulations get heavy.
- Snow loads. If you see a sagging roofline or hear unusual creaking, seek a professional evaluation. For code and local snow‑load questions, contact the Town’s Building Department via the Town of Wolfeboro.
Trees, driveways, and access
- Tree work. Trim or remove hazardous limbs, especially near structures and driveways.
- Plow access. Install driveway markers and confirm your plowing contract and response time.
- Emergency access. Keep paths to fuel tanks, meters, and main entries clear for responders and service crews.
Insurance, safety, and documentation
- Coverage. Review winter‑related perils, vacancy rules, and any minimum heat requirements with your insurer.
- Detectors. Test smoke and CO detectors. Replace batteries and add detectors on each floor if needed.
- Records. Photograph the property before closing it for the season and save receipts from professional services. For disaster readiness and claims information, visit FEMA.

FAQs
What temperature should I set in a vacant Wolfeboro lake home?
- Many contractors commonly recommend 50 to 55 degrees to reduce freeze risk, but confirm with your HVAC professional and your insurance carrier. For long vacancies, full plumbing winterization may be safer.

- Remove docks and store boats before ice forms. Confirm removal windows and procedures with the Town’s Harbor Master or your marina and schedule early.
Can I drain my home’s plumbing myself before winter?
- You can handle simple steps like hoses and exterior spigots, but full winterization of plumbing lines, toilets, and the water heater is best done by a licensed plumber.
How do I prevent roof ice dams in Wolfeboro’s climate?
- Improve attic insulation, seal air leaks, and maintain ventilation. After storms, remove excess roof snow safely or hire professionals. Heated cables can help in some cases.
Will my septic system freeze if I leave for the season?
- Properly installed systems are below the frost line and benefit from snow cover. Problems arise with exposed components or recent disturbances. Insulate exposed parts and consider pumping before a long vacancy based on professional advice.
