Winter Home Maintenance Checklist

Homeowner Summary

Winter is the most dangerous season for your home. Freezing temperatures, ice, snow, and wind create conditions for the most expensive and destructive failures a home can experience: burst pipes ($5,000-$70,000 in damage), furnace failures in sub-zero conditions (risk of secondary pipe freezing throughout the house), ice dams ($5,000-$15,000 in roof and interior damage), chimney fires ($20,000+ in damage), and roof collapse from snow load (catastrophic loss).

Unlike other seasons where maintenance is primarily about preparation, winter maintenance is about vigilance and prevention in real time. You are managing active threats every time the temperature drops below 32 degrees F (0 degrees C). The stakes are highest during extended cold snaps, when multiple systems are under sustained stress and service providers are overwhelmed with emergency calls.

If you completed the fall checklist, your home is well-prepared. Winter maintenance focuses on monitoring systems under load, preventing specific cold-weather failures, and responding quickly to emerging problems. The items in this checklist should be checked regularly throughout the winter months, not just once.

Winter Maintenance Checklist

Prevent Frozen Pipes (November-March)

Frozen pipes are the single most costly preventable winter failure. Water expands 9% when it freezes, generating pressures up to 25,000 PSI — more than enough to split copper, PEX, or PVC pipes. The damage occurs not at the freeze point but downstream when the ice blockage traps expanding water with no relief.

DIY (Homeowner)

• [ ] Know your vulnerable pipes — pipes in exterior walls, unheated crawlspaces, garages, attics, and under cabinets on exterior walls are at highest risk
• [ ] Keep the thermostat at 55 degrees F (13 degrees C) minimum at all times, including at night and when away from home — never set lower to save energy during freezing weather
• [ ] Open cabinet doors under kitchen and bathroom sinks on exterior walls during cold snaps to allow warm room air to reach pipes
• [ ] Let faucets drip at a slow, steady drip during extreme cold (below 20 degrees F / -7 degrees C) — the slight flow prevents freezing; both hot and cold lines
• [ ] Insulate exposed pipes in unheated areas with pipe insulation foam ($0.50-$2.00 per linear foot) or heat tape for high-risk pipes ($15-$50 per section)
• [ ] Seal air leaks near pipes — cold air blowing on pipes accelerates freezing; seal gaps around pipes where they penetrate exterior walls
• [ ] Keep the garage door closed if water supply lines run through the garage
• [ ] If a pipe freezes (no flow from faucet): keep the faucet open, apply heat with a hair dryer or heating pad starting from the faucet end and working toward the frozen section — never use an open flame; call a plumber if you cannot locate the freeze or if you suspect the pipe has already burst
• [ ] Know your main water shutoff valve location — if a pipe bursts, shutting off the main valve within minutes limits damage from thousands of dollars to hundreds

Professional

• [ ] Consider pipe monitoring sensors ($50-$200 per sensor) for high-risk areas — these alert you to temperature drops near pipes before freezing occurs
• [ ] For homes with chronic freeze issues, consult a plumber about rerouting vulnerable pipes away from exterior walls ($500-$3,000 depending on scope)

Timing: Active monitoring whenever the forecast calls for temperatures below 32 degrees F (0 degrees C), with heightened vigilance below 20 degrees F (-7 degrees C).

Check Insulation (December-January)

Winter is when insulation deficiencies become most apparent. Cold spots, drafts, ice forming on interior window surfaces, and uneven heating all point to insulation gaps.

DIY (Homeowner)

• [ ] Check for cold spots on walls and ceilings — hold your hand near interior surfaces of exterior walls; noticeably cold areas indicate missing or compressed insulation
• [ ] Look for frost or condensation on interior window surfaces — persistent condensation indicates excessive moisture (ventilation issue) or extremely cold glass surface (window upgrade needed)
• [ ] Inspect visible insulation in the attic — look for areas that are thin, displaced by wind, compressed, or water-damaged
• [ ] Check the attic hatch or pull-down stairs for air leaks — these are frequently the largest single source of heat loss into the attic
• [ ] Inspect the rim joist area in the basement (where the floor structure meets the foundation wall) — this is often uninsulated and a major heat loss point
• [ ] Use an infrared thermometer ($20-$50) to measure surface temperatures — exterior walls should be within 5 degrees F of interior walls; larger differences indicate insulation problems

Professional

• [ ] Schedule a home energy audit ($200-$400) if heating bills are unexpectedly high — includes thermal imaging that reveals insulation gaps invisible to the naked eye
• [ ] Insulation upgrades (attic: $1,500-$3,000 for blown-in; walls: $2,000-$5,000 for injection foam) can typically be done in winter with minimal disruption

Timing: Assess during the first sustained cold period (multiple days below freezing). Schedule professional work as needed.

Ice Dam Prevention (December-February)

Ice dams form when heat escaping through the roof melts snow, which refreezes at the colder eave. Water pools behind the ice dam and backs up under shingles, leaking into the home. They cause interior water damage, ruined insulation, mold growth, and damaged gutters.

DIY (Homeowner)

• [ ] Remove excess snow from the roof after heavy snowfall using a roof rake from the ground — clear at least the first 3-4 feet (1-1.2 m) from the eave; never climb onto a snow-covered or icy roof
• [ ] Do not chop ice dams with an ax or hammer — you will damage the roof and shingles
• [ ] As a temporary measure, fill a nylon stocking with calcium chloride ice melt and lay it across the ice dam perpendicular to the gutter — this melts a channel for water to drain; do not use rock salt (sodium chloride), which corrodes metal and damages landscaping
• [ ] Check the attic for signs of water intrusion during and after ice dam events — stains on rafters, wet insulation, dripping water
• [ ] Verify attic ventilation is functioning — soffit vents must not be blocked by insulation (use baffles); ridge or roof vents must be clear
• [ ] Ensure adequate attic insulation — the attic floor should have at least R-38 to R-60 of insulation depending on climate zone; insufficient insulation is the root cause of most ice dams

Professional

• [ ] For chronic ice dam problems, hire a contractor to perform a thermal assessment and install additional attic insulation and air sealing ($1,500-$5,000) — this addresses the root cause
• [ ] Consider professional ice dam removal using steam ($300-$600 per event) — never hire anyone who uses a pressure washer or mechanical removal on the roof
• [ ] Install heat cables along the eave and in gutters as a last resort ($300-$800 installed) — these treat the symptom, not the cause

Timing: Monitor after every snowfall greater than 4 inches. Proactive measures (insulation, ventilation) should be completed before winter.

Fireplace and Chimney Safety (December-February)

If you use a fireplace or wood stove, ongoing winter safety practices are essential in addition to the fall inspection and cleaning.

DIY (Homeowner)

• [ ] Burn only seasoned hardwood — wood should be split and dried for at least 6-12 months with moisture content below 20% (check with a $20 moisture meter); unseasoned wood produces excessive creosote
• [ ] Never burn treated wood, plywood, particle board, wrapping paper, or trash — these produce toxic fumes and can cause chimney fires
• [ ] Use a fireplace screen or glass doors to contain sparks
• [ ] Open the damper fully before lighting and leave it open until the fire is completely extinguished and ashes are cold
• [ ] Check the chimney exterior periodically during winter — look for creosote staining on the exterior (indicates internal leaks), damaged cap, or missing spark arrestor
• [ ] Maintain a 3-foot (1 m) clearance between the fireplace and any combustible materials (furniture, curtains, holiday decorations)
• [ ] Dispose of ashes safely — let ashes cool for at least 72 hours in the fireplace, then transfer to a metal container with a tight-fitting lid stored outdoors on a non-combustible surface at least 10 feet (3 m) from the house
• [ ] Install a carbon monoxide detector within 15 feet (5 m) of the fireplace if not already present

Timing: Ongoing throughout fireplace usage season. Safety practices apply to every fire.

Test Sump Pump (December-January)

The sump pump protects your basement from flooding. Winter presents two risks: power outages during storms disable the pump, and spring snowmelt combined with frozen ground saturates the soil.

DIY (Homeowner)

• [ ] Test the sump pump manually — pour a 5-gallon bucket of water into the sump pit; the pump should activate, remove the water, and shut off automatically within 20-30 seconds
• [ ] Check the discharge pipe — verify it is not frozen or clogged; the discharge point should be at least 6 feet (1.8 m) from the foundation and directed away from the house
• [ ] Clean the sump pit — remove debris, gravel, and sediment that can clog the pump intake
• [ ] Test the check valve — listen for water flowing back into the pit after the pump shuts off; a gurgling sound indicates a failed check valve ($20-$50 to replace)
• [ ] Verify the backup system — if you have a battery backup sump pump, test it by unplugging the primary pump and triggering it with water; check the battery charge level
• [ ] Consider adding a battery backup ($200-$600) if you do not have one — power outages during winter storms are common and occur precisely when flooding risk is highest

Timing: Test monthly from December through April. Test after every power outage.

---

Change Filters (Monthly Through Winter)

Your HVAC system runs more hours during winter than any other season. Filters clog faster under heavy use, and a clogged filter during peak heating can cause the system to overheat and shut down.

DIY (Homeowner)

• [ ] Check the furnace filter monthly — hold it up to a light; if you cannot see light through it, replace it regardless of the scheduled change date
• [ ] Replace 1-inch filters monthly during winter; 4-inch media filters every 2-3 months
• [ ] Use the correct filter size and type — check the existing filter or the furnace manual for specifications; an ill-fitting filter allows unfiltered air to bypass
• [ ] Do not upgrade to a significantly higher MERV rating without verifying the furnace can handle the increased static pressure — a MERV 13+ filter on a system designed for MERV 8 can restrict airflow enough to damage the heat exchanger
• [ ] Stock extra filters so you always have a replacement on hand — running without a filter is worse than running with a dirty one (debris damages the blower and heat exchanger)
• [ ] Change or clean the humidifier pad or filter if you have a whole-home humidifier (every 1-2 months during winter)

Timing: Check every 4 weeks from the start of heating season through March.

---

Check Caulking and Seals (January-February)

Cold weather causes caulk and sealants to contract, sometimes opening gaps that were sealed in fall. A mid-winter check catches failures early.

DIY (Homeowner)

• [ ] Inspect caulking around windows and doors from the interior — feel for cold air drafts with your hand or use the candle test (flame deflection indicates air movement)
• [ ] Check the weather seal on the garage door — cold air infiltrating the garage affects any rooms above or adjacent
• [ ] Inspect caulking around plumbing penetrations in exterior walls — under sinks, around hose bibs, and where pipes exit the foundation
• [ ] Apply temporary interior caulk (removable rope caulk, $3-$5 per roll) to drafty windows if permanent exterior caulking cannot be done until spring (exterior caulk does not adhere well below 40 degrees F / 4 degrees C)
• [ ] Check dryer vent flap — verify it closes when the dryer is not running; a stuck-open flap is a major cold air entry point
• [ ] Apply window insulation film ($10-$20 per 5-window kit) to single-pane or drafty windows for temporary winter improvement

Timing: Check during the coldest period of winter, when air leaks are most noticeable.

---

Snow and Ice Removal (Ongoing)

Proper snow and ice removal protects your home's structure, prevents personal injury, and maintains access for emergency vehicles.

DIY (Homeowner)

• [ ] Clear snow from walkways and driveways within 24 hours of snowfall — many municipalities require this by ordinance
• [ ] Apply ice melt judiciously — calcium chloride is effective to -25 degrees F (-32 degrees C) and is gentler on concrete than rock salt; magnesium chloride is safest for concrete and vegetation but more expensive; avoid sodium chloride (rock salt) on concrete less than 1 year old or on pavers
• [ ] Keep the path to your furnace exhaust and intake vents clear — snow blocking the furnace exhaust pipe can cause carbon monoxide buildup inside the home; this is a life-safety issue
• [ ] Clear snow away from the foundation — piled snow melting against the foundation saturates the soil and can cause basement leaks or foundation damage
• [ ] Remove snow from window wells — accumulated snow in window wells can break the glass or leak into the basement when it melts
• [ ] Monitor roof snow load — most residential roofs are designed for 20-40 PSF (pounds per square foot) of snow load; fresh snow weighs approximately 1-5 PSF per foot of depth; wet, packed snow can weigh 20+ PSF per foot; if in doubt, hire a professional for removal
• [ ] Keep fire hydrants and gas meters accessible — clear snow to maintain 3-foot (1 m) access around both
• [ ] Inspect the roof after heavy snowfall or ice storms from the ground — look for sagging, ice dam formation, or damaged flashing

Professional

• [ ] Hire professional roof snow removal ($200-$500 per event) if snow depth exceeds 2 feet or if the roof is showing signs of stress — do not attempt roof snow removal yourself due to fall risk and roof damage potential

Timing: Ongoing throughout winter. Immediate attention after each snowfall or ice event.

Warning Signs

Winter emergencies require immediate response. These signs indicate urgent problems:

• No water flow from a faucet on an exterior wall (pipe is frozen — act immediately before it bursts)
• Water appearing on walls or ceilings during or after snowfall (active roof leak or ice dam — document and mitigate immediately)
• Furnace running continuously without reaching the setpoint (system failure developing — call for service before complete failure)
• Carbon monoxide detector alarming (evacuate immediately, call 911 — do not re-enter until cleared by emergency services)
• Burning smell from the furnace that persists beyond the first hour of seasonal use (potential electrical or mechanical failure)
• Icicles forming at the roofline (precursor to ice dams — monitor closely and rake snow from the eave)
• Sagging roof sections (snow load may be approaching structural limits — evacuate the area below and call for emergency removal)
• Water in the basement during a thaw cycle (sump pump may be overwhelmed or failed — check immediately)
• Gas odor near the furnace, water heater, or gas meter (leave the house immediately, do not operate any switches, call the gas company from outside)

Pro Detail

Dealer Upsell Opportunities: Winter

Winter service calls are almost exclusively emergency-driven. The key for dealers is converting emergency repairs into relationship-building and upgrade opportunities.

| Service | Typical Price | Closing Rate | Notes | |---------|--------------|-------------|-------| | Emergency furnace repair | $200-$2,500 | Very high | Premium rates accepted due to urgency | | Furnace replacement (emergency) | $3,000-$8,000 | High | Failed system during cold snap; fast decision | | Pipe thaw and repair | $200-$500 (thaw) / $1,000-$10,000 (burst repair) | Very high | Urgent; homeowner highly motivated | | Ice dam removal (steam) | $300-$600 per event | High | Recurring revenue during ice dam season | | Insulation upgrade (post-event) | $1,500-$5,000 | Medium-high | Best sold immediately after ice dam or high heating bill | | Battery backup sump pump | $200-$600 | Medium-high | Sold after power outage or flooding event | | Generator installation | $3,000-$12,000 | Medium | Post-outage motivation | | Water damage restoration | $2,000-$20,000 | Very high | Referral opportunity to restoration partners |

Winter Service Strategy: Every emergency call is a relationship opportunity. The technician who shows up at 2 AM when the furnace fails earns trust that converts to a long-term service relationship. Follow up within 48 hours of every emergency call with a comprehensive home assessment offer. Homeowners who just experienced a failure are the most receptive to preventive maintenance plans.

Code & Compliance

• Furnace exhaust venting must terminate per manufacturer specifications and local code — typically 12 inches above expected snow depth and at required clearances from windows, doors, and air intakes
• Ice and snow removal from public sidewalks is required by municipal ordinance in most jurisdictions, with liability for slip-and-fall injuries
• Roof snow removal workers must comply with OSHA fall protection standards (29 CFR 1926.501)
• Carbon monoxide detector requirements: 37 states require CO detectors; most require detectors on every habitable level and near sleeping areas
• Space heater use must comply with manufacturer clearance requirements and local fire codes — the leading cause of home heating fires

Cost Guide

| Task | DIY Cost | Professional Cost | Notes | |------|----------|------------------|-------| | Pipe insulation | $0.50-$2 per linear foot | $3-$5 per linear foot | High-value DIY | | Heat tape (electric) | $15-$50 per section | $100-$300 installed | For chronic freeze locations | | Pipe freeze repair (thaw only) | N/A | $200-$500 | Before pipe bursts | | Burst pipe repair + water damage | N/A | $1,000-$70,000 | Depends on extent of damage | | Roof snow removal (rake) | $30-$50 (roof rake) | $200-$500 per event | DIY only from ground level | | Ice dam removal | $15-$25 (calcium chloride) | $300-$600 per event | Steam removal preferred | | Furnace filter (monthly) | $5-$40 | N/A | Stock in advance | | Window insulation film | $10-$20 per 5-pack | N/A | Significant comfort improvement | | Sump pump battery backup | $200-$600 | $300-$800 installed | Insurance against flooding |

Total estimated winter maintenance cost: $100-$300 for routine monitoring and filter changes (excluding emergency repairs).

Energy Impact

Winter heating is the largest single energy expense for homes in cold climates, often exceeding $1,000 for the season. Winter maintenance directly affects costs:

• A clogged filter forces the furnace to work harder, increasing gas or electricity consumption by 5-15%
• Air leaks that opened since fall can increase heating costs by 5-10% — mid-winter sealing with temporary measures recovers most of the loss
• Window insulation film can reduce heat loss through windows by 25-40%, providing measurable comfort improvement and energy savings for minimal cost
• Keeping the thermostat at a constant moderate temperature (68-70 degrees F / 20-21 degrees C) rather than large setbacks prevents the system from running at maximum capacity for extended periods; however, a moderate nighttime setback of 5-8 degrees F still saves 5-10% on heating with a programmable thermostat
• Ceiling fans on low clockwise provide up to 10% savings in rooms with high ceilings by pushing warm air down

Shipshape Integration

SAM operates in high-alert mode during winter, with the tightest monitoring thresholds of any season:

• Freeze risk alerts: SAM cross-references indoor temperature data with outdoor forecasts to predict pipe freeze risk. When conditions approach freeze thresholds (outdoor below 20 degrees F with indoor temps dropping or windchill factors increasing), homeowners receive specific alerts with actions: open cabinets, drip faucets, verify thermostat setting.
• Furnace performance monitoring: SAM tracks furnace runtime and cycling patterns. If the system begins running more than 80% of the time at current outdoor temperatures, an alert triggers suggesting service before complete failure. If the system stops cycling entirely (constant run or no run), an emergency alert is sent.
• Energy anomaly detection: SAM compares daily energy consumption to expected levels for current weather conditions and the home's thermal profile. Sudden increases trigger investigation alerts — the homeowner may have developed an air leak, a duct disconnection, or a heating system efficiency problem.
• Ice dam risk modeling: For homes in cold climates, SAM models ice dam risk based on attic insulation levels, outdoor temperature, snowfall, and temperature cycling patterns (freeze-thaw). High-risk conditions trigger preventive alerts (rake snow from eaves).
• Emergency response coordination: If SAM detects a potential emergency (water leak sensor alarm, furnace failure, CO detection), it immediately alerts the homeowner, provides emergency instructions, and notifies the assigned Shipshape dealer for priority service dispatch.
• Home Health Score: Winter is the highest-risk period for the Home Health Score. Active monitoring and prompt response to alerts maintains the score. Ignoring freeze warnings or running with an overdue furnace filter progressively drops the score. The score provides dealers with an at-a-glance triage tool for their customer base during winter emergencies.
• Post-event assessment: After winter storms, extreme cold events, or ice dam formation, SAM prompts homeowners to complete a post-event inspection checklist and documents any findings for dealer follow-up.
