First-Time Homeowner Maintenance Checklist

Most first-time homeowners go from "I have to fix nothing" (renting) to "I have to fix everything" (ownership) without any roadmap. The result is a lot of expensive reactive repairs that could have been prevented with straightforward regular maintenance.

The good news: maintaining a home is not complicated. It is mostly about consistency — doing the right things at the right times, every year.

Your first 30 days

Before you get into seasonal routines, there are things that should happen immediately after you move in:

• Change all locks — you do not know who has keys to the house from previous owners, contractors, or real estate agents.
• Test all smoke detectors and CO detectors — replace batteries in everything. Note locations and ages. Smoke detectors should be replaced every 10 years.
• Locate your shutoffs — find the main water shutoff, the gas shutoff, and the main electrical panel. Know how to turn each off in an emergency.
• Replace HVAC filters — do this immediately and note the filter size. Set a recurring reminder to do this every 1–3 months.
• Flush your water heater — sediment accumulates at the bottom of water heaters and reduces efficiency. Connect a hose to the drain valve and flush it.
• Check your gutters — clean them out if needed. Clogged gutters cause water to back up under roofing materials and pool at the foundation.
• Get to know your inspection report — if you received a home inspection, go back through it now that you are in the house. Check the specific items the inspector flagged and confirm what was addressed before closing.

Spring checklist (March – May)

Spring maintenance focuses on recovering from winter and preparing for warmer months:

• Walk the exterior and look for damage from winter: cracked caulk around windows and doors, damaged siding, cracked pavement
• Inspect the roof from the ground (binoculars help) for missing or lifted shingles, damaged flashing, and debris in valleys
• Clean gutters and downspouts after spring pollen and debris season
• Check that downspouts direct water at least 6 feet from the foundation
• Service the air conditioning system — schedule an HVAC tune-up before cooling season starts
• Test the air conditioning to make sure it is operational before it gets hot
• Check window and door screens for damage; clean and reinstall storm windows if applicable
• Inspect decks, patios, and fences for winter damage; look for rot, loose fasteners, and unstable boards
• Check exterior paint and siding for peeling or bubbling — these allow moisture to penetrate
• Restock your emergency supplies: flashlights, batteries, a basic tool kit

Summer checklist (June – August)

Summer is the best season for exterior work and long-term projects:

• Deep-clean kitchen appliances: clean the refrigerator coils (bottom front or back), descale the dishwasher, clean the oven hood filter
• Check for signs of pest activity: look for mud tubes near the foundation (termites), droppings, or entry points around pipes
• Replace HVAC filter — monthly if you have pets, quarterly if you do not
• Check and clean dryer vent duct (this is a fire hazard when clogged — do it at least annually)
• Test your sump pump by pouring a bucket of water into the pit — confirm it activates and drains properly
• Inspect and clean the garage door mechanism; test the auto-reverse safety feature
• Caulk around exterior windows and doors where the old caulk has cracked or separated
• Check irrigation system for leaks, misaligned heads, and proper coverage

Fall checklist (September – November)

Fall is the most important maintenance season. You are preparing for cold weather, and anything you skip now will cost more to fix in January:

• Service your heating system — schedule an HVAC tune-up before you need it. Technicians are busy once the cold hits; schedule in September.
• Clean gutters after leaves fall — this is critical. Blocked gutters cause ice dams in winter and water damage in spring.
• Drain and store garden hoses; shut off exterior hose bibs and insulate them
• Have your chimney and fireplace inspected and cleaned if you use them
• Check attic insulation and ventilation — inadequate attic insulation is a major source of energy loss and can cause ice dams
• Reverse ceiling fans to clockwise direction (pushes warm air down)
• Seal any gaps or cracks in the foundation, around pipes, and in the exterior where cold air or pests can enter
• Test heating before you need it; bleed radiators if you have a hot-water heating system
• Replace HVAC filter before heating season begins
• Stock emergency winter supplies: extra heating fuel if applicable, generator fuel, ice melt

Winter checklist (December – February)

Winter maintenance is about preventing damage from cold weather and staying safe:

• Know how to prevent frozen pipes — if temperatures will drop well below freezing, let faucets drip and know where your main shutoff is
• After heavy snow, check the roof for ice dams — ridges of ice at the eave that can force water under shingles
• Keep the furnace filter clean — systems work harder in winter and a clogged filter reduces efficiency and lifespan
• Check and restock smoke detector and CO detector batteries
• Inspect the basement and crawl space for condensation or water intrusion — heating season changes humidity conditions
• Use winter to plan spring projects — get quotes, schedule contractors for the busy season

Tasks to do every year (regardless of season)

• Replace HVAC filters (every 1–3 months)
• Test smoke detectors and CO detectors (monthly)
• Clean dryer vent duct
• Service HVAC (heating in fall, cooling in spring)
• Inspect the roof, gutters, and downspouts
• Walk the exterior looking for damage, water intrusion, or pest activity
• Flush the water heater
• Check fire extinguisher pressure gauge

Keep a maintenance log

The most valuable habit you can develop as a homeowner is keeping a record of what you have done and when. When your water heater fails and you cannot remember when it was last serviced — or when you go to sell and a buyer asks about the roof — having a maintenance history is invaluable.

Log the date, what was done, who did it, what it cost, and attach any invoices or warranties. Over time, this becomes your home's permanent maintenance record.
