Routine maintenance isn’t exciting, but the math makes a strong case for it. Every dollar spent on upkeep prevents up to $100 in repair costs—and water damage claims average over $42,000 while fire-related claims top $68,000. Most homeowners only act when something breaks. By then, the cheap fix is gone.
Here’s what to do each season, what it costs, and when to stop doing it yourself.
How Much to Budget
The standard guidance is 1% of your home’s purchase price per year—so a $300,000 home needs roughly $3,000 annually, or $250 per month set aside. Most homeowners spend between $1,400 and $2,300 on regular maintenance, not counting unexpected repairs.
Age shifts that number considerably. If the building is less than 26 years old, the average number is 3%. Houses built before 2010 get closer to 5%. Older homes require up to 8%.
Geography matters too—New England homes cost roughly twice as much to maintain as those in the East South Central states. If you own an older property in a high-cost region, a 4% annual savings target is more realistic than 1%.
Spring
Exterior
Start with gutters — clean by hand, flush with a hose, and confirm water drains at least 3 feet from the foundation. Check for rust, holes, and sagging fasteners; seal leaks with butyl rubber caulk, which holds up through temperature swings better than silicone. From the ground with binoculars, look for missing, curled, or stained shingles, cracked flashing around chimneys and vents, and any water stains visible through the attic. A professional roof inspection runs less than emergency repairs once the damage has spread.
Interior
Book HVAC service early—refrigerant check, coil cleaning, condensate drain test. This runs $150–$200 and is far cheaper than an emergency call in July. Test the sump pump by pouring water into the pit; it should activate, drain, and shut off. Check pipes under sinks and in basements for moisture or corrosion. Test outdoor faucets slowly for leaks from freeze damage. Flush the water heater to clear sediment that builds up and reduces heating efficiency.
Summer
Exterior
Power wash vinyl siding on a wide-angle setting — trisodium phosphate in the mix handles mildew that won’t come off otherwise. Check for cracks, warping, and pest entry points while you’re at it. Vegetation within 6 inches of the siding traps moisture against it — trim it back.
Asphalt driveway cracks under ½ inch fill well with patch compound during warm weather, when it sets properly.
Wood decks need a full sequence: power wash, dry completely, then seal. Composite decks need only cleaning.
Interior
Replace HVAC filters every 30–60 days during peak cooling season—every 45 days if you have pets. Clogged filters restrict airflow by up to 15% and drive up energy costs while shortening equipment life. MERV 13 or higher filters improve air quality noticeably. Clean kitchen and bathroom exhaust fans to keep heat and humidity moving out.
Fall
Exterior
Disconnect and drain garden hoses before storing them. Shut off the interior valve to each outdoor faucet, open the exterior tap to clear any remaining water, and leave it open through winter. Foam covers over exposed spigots add another layer of protection. Insulate exposed pipes in unheated spaces with foam tubes—match the tube diameter to your pipe.
Modern AC units don’t need covers. Covers trap moisture and attract rodents; if overhead trees drop debris, a piece of plywood on top is enough. Never cover a heat pump—it runs year-round.
Interior
Schedule furnace service before the heating season starts. Professional maintenance runs $162–$265 and covers gas connections, heat exchanger inspection, safety controls, and burner cleaning. Replace filters monthly once heating is running regularly. The National Fire Protection Association recommends annual chimney cleaning—creosote buildup is the primary cause of chimney fires. It’s better to schedule it before winter comes and the fireplace is used on a daily basis.
Winter
Exterior
Ice dams form when attic heat melts snow unevenly, causing meltwater to refreeze at the roof edge and back up under shingles. Clean gutters in fall to reduce trapped water. After heavy snowfall, use a roof rake from the ground to clear snow from the lower roof edge. Check attic ventilation—keeping attic temperatures close to outdoor air temperature reduces freeze-thaw cycles. After winter storms, walk the perimeter: missing shingles, loose flashing, detached gutters, and standing water near the foundation all need attention before spring.
Interior
Set the thermostat to at least 55°F when the house is empty. Open cabinet doors under sinks on exterior walls to let warm air circulate around pipes. When temperatures drop below 20°F, a slow drip from faucets on exterior walls keeps pressure from building up enough to freeze the pipes. Heat tape on vulnerable pipes—thermostatically controlled, activating around 38°F—handles the rest. Test carbon monoxide detectors monthly through the heating season and check that heating vents stay clear of snow.

Monthly and Quarterly Tasks
HVAC filters go every 90 days in standard homes, every 60 with pets, every 20–45 days with allergy concerns. Test smoke and carbon monoxide detectors monthly, check under-sink drains for slow drainage or moisture, and clean kitchen exhaust filters before grease has a chance to build up.
Gutters need cleaning in spring and fall—every three months if there’s heavy tree coverage. Flush the water heater every 6–12 months depending on water hardness. Run a vinegar cycle through the dishwasher quarterly and check refrigerator door seals for wear.
DIY vs. Professional
- DIY: filter changes, detector tests, gutter cleaning, sump pump testing, pipe insulation, deck washing and sealing, minor caulking.
- Professional: HVAC service, furnace tune-ups, chimney sweeping, roof repairs, electrical work, gas line work, structural modifications. Licensed contractors carry insurance and pull permits—skipping this creates liability exposure when you sell.
Monthly tasks take 15–30 minutes. Seasonal tasks run 2–4 hours. Professional HVAC service runs $150–$300 per visit. Water heater flushing is a $20–$50 DIY job or $200–$600 if you hire it out. Hold onto receipts — a documented maintenance history carries real weight when you sell.
Bottom Line
Make sure to not skip the maintenance- it can cost you 3 to 5 times more than if you do everything on schedule. Handle what you can, hire out the rest, and track everything.
