New Jersey home maintenance checklist: what to do each season
New Jersey's freeze-thaw winters, humid summers and coastal storms make seasonal maintenance worthwhile. Clean gutters and check the roof in spring and fall, service heating before winter and cooling before summer, protect outdoor plumbing from freezing, and test smoke and carbon monoxide alarms regularly. Small, regular checks catch problems before they become expensive repairs.

Spring
Clean gutters and confirm downspouts drain away from the foundation. Look over the roof from the ground for missing or damaged shingles after winter. Test the sump pump. Schedule air conditioning service before the first hot week. Check for winter damage to siding, caulk and exterior wood.
Summer
Replace HVAC filters on the schedule your system requires. Watch for condensation or water around the AC air handler. Trim vegetation back from siding and the AC condenser. Inspect decks and railings for loose boards or fasteners.
Fall
Clean gutters again after leaves drop. Have the heating system serviced. Shut off and drain outdoor faucets and irrigation. Seal gaps around windows and doors. Clean the dryer vent.
Winter
Keep an eye out for ice dams along roof edges. Keep heat on in vacant areas to prevent frozen pipes, and know where your main water shutoff is. Clear snow from furnace and dryer exhaust vents.
Year-round
Test smoke and CO alarms monthly and replace batteries as the manufacturer directs. Consider radon testing — New Jersey's Department of Environmental Protection recommends testing homes for radon.
What affects the answer
- Age of the home and its major systems.

What homeowners often overlook
- Dryer vents should be cleaned regularly — lint buildup is a fire risk.

- Sump pumps should be tested before spring rains.
- New Jersey requires smoke and carbon monoxide alarm certification when a one- or two-family home is sold.
Questions to ask a contractor
- What exactly is included in this service visit?
- Will you provide a written report of what you found?
- Are you licensed for this trade in New Jersey (HVAC, plumbing, electrical)?
When to get a professional assessment
- Smell of gas or a CO alarm sounding — leave the home and call your utility or 911.
- Water in the basement that a sump pump can't keep up with.
- Frozen or burst pipes.
- Any electrical panel or wiring concern.
