Marin Home Winter-Ready Checklist: Boost Comfort & Value

The first big Marin storm tests everything, from your roof to your yard drains. If you want a cozy winter and a confident spring sale, a little prep now goes a long way. This guide gives you a Marin‑specific checklist to protect your home, improve comfort, and spotlight upgrades that can boost resale value. Let’s dive in.

Why winter prep matters in Marin

Marin sees a cool, wet season from roughly November through March, with about 32 to 34 inches of annual rain in the San Rafael area, according to local climate normals for San Rafael. That means heavy rain, wind, and saturated ground are routine. Flood exposure varies by neighborhood, and the Marin County Flood Control District monitors flood control zones. Wildfire and wind‑blown embers remain a year‑round concern in many parts of the county, so CAL FIRE defensible space guidelines apply in winter too.

Exterior first line of defense

Roof inspection. Scan for missing shingles, cracked flashing, and worn valleys. If your roof is older, schedule a licensed inspection before peak storms. Early fixes prevent costly interior damage.

Gutters and downspouts. Clean gutters, secure hangers, and confirm downspouts send water well away from the foundation. Leaf screens help in tree‑lined areas. Clogged gutters contribute to leaks and mold, and the EPA warns that wet materials can develop mold within 24 to 48 hours.

Ember‑resistant details. Replace cracked roof tiles, seal roof‑to‑wall joints, and plan for Class A roofing at replacement where appropriate. These steps reduce ember entry during windy events.

Keep water away from your foundation

• Ensure soil slopes away from the house for at least the first few feet where feasible.
• Extend downspouts or use splash blocks so water does not pond near the structure.
• Clear private swales and drains, and check any low spots before the first big storm.
• If you are near creeks or in known flood areas, review local practices on the Marin County Flood Control District site.

Trees, vegetation, and defensible space

Create and maintain defensible space using local guidance:

• Focus on Zone 0, the first 0 to 5 feet around your home. Keep this area free of combustible mulch and debris.
• In Zones 1 and 2, thin vegetation, remove dead material, and prune limbs away from structures.
• Use the Central Marin Fire defensible space program for local standards, and explore Marin Wildfire home hardening and resident programs for evaluations and chipper days.

Plumbing and water systems

• Insulate exposed water pipes and outdoor spigots, especially on shaded sides of the home.
• Test your water heater’s pressure‑relief valve and consider a pre‑season service.
• If you have a sump pump, test it, check the float, and consider a battery backup.
• On septic, avoid driving over the leach field and confirm cleanouts are accessible.

Heat, ventilation, and indoor comfort

• Schedule HVAC service, replace filters, and test thermostats for reliable heat.
• If you use a fireplace or wood stove, get the chimney inspected and swept before use.
• Seal major air leaks at doors and windows, then top up attic insulation if needed. Air sealing plus attic insulation can noticeably improve comfort and energy costs.
• Income‑qualified households can check the PG&E Energy Savings Assistance program for no‑cost weatherization and safety upgrades.

Manage indoor moisture and mold

Dry wet materials within 24 to 48 hours after leaks or storms to prevent mold. Run bathroom and kitchen exhaust fans, use a dehumidifier after heavy rain, and address any ceiling stains quickly. For cleanup basics, see EPA guidance on mold and moisture.

Safety and insurance tune‑up

• Confirm working smoke alarms on every level and in or near sleeping areas. Test monthly and replace smoke alarms about every 10 years. See NFPA smoke alarm guidance.
• Install carbon monoxide alarms if you have fuel‑burning appliances or an attached garage.
• Prepare for outages with power banks and a plan for charging essentials.
• Review your homeowners policy. Standard policies typically exclude flood. If you are in a FEMA Special Flood Hazard Area, your lender may require flood insurance, and NFIP policies often have a 30‑day waiting period. Start with Marin County Public Works SFHA guidance.

Decks, steps, and hardscape

Check deck boards and railings for rot or loose fasteners, especially at ledger flashing. Clear leaves from walkways and driveways to reduce slip hazards. Schedule professional inspections for older elevated decks.

Quick seasonal timeline

• Early fall: roof and gutter service, tree pruning, HVAC and water‑heater checks, smoke and CO alarm tests.
• Late fall, before first big storms: clear gutters again, set downspout extensions, test sump pump, and refresh emergency supplies.
• After heavy storms: check the attic and ceilings for leaks, dry any wet materials quickly, and re‑clear drains and debris.

Smart upgrades that boost value

• Attic insulation and air sealing improve comfort and running costs, which buyers value.
• Heating upgrades, like high‑efficiency heat pumps, can lower operating costs. Incentives change often, so start with the California Energy Commission home energy resource hub to see current options.
• Target curb appeal and moisture‑risk repairs. Fresh entry and garage doors, clean gutters, and dry basements make a strong first impression.
• Document maintenance with dated receipts and permits. Organized records reduce buyer friction.

Planning to sell soon?

Take care of roof, drainage, HVAC, and safety items before listing. Keep proof of service and permit records, and verify required smoke and CO alarms are installed and working. If your parcel is in or near a mapped flood area, note any mitigation steps and insurance details in your disclosures. Clean, safe, and well‑documented homes show and appraise better.

What is Zone 0 defensible space and why is it important?

• Zone 0 is the 0 to 5 feet around your home, kept free of leaves, mulch, and other combustibles to reduce ember ignition risk.

Do I need flood insurance if I am not in an SFHA?

• It is optional outside SFHAs, but some owners choose a policy for added protection. Ask your insurance agent to price both building and contents coverage.

Which energy upgrades have rebates in Marin right now?
