Most expensive home repairs start as cheap ones that nobody noticed: a clogged gutter that becomes a wet basement, a $15 furnace filter that becomes a $600 blower motor, a cracked bead of caulk that becomes rotted window trim. A home doesn't need constant attention, but it does need the right attention at the right time of year. In a climate like Ohio's, with hard freezes, spring thaws and humid summers, timing matters more than in most places.
A common rule of thumb is to set aside 1% to 2% of your home's value each year for maintenance and repairs: about $3,000 to $6,000 a year on a $300,000 home. Older homes and homes with original systems sit at the high end.
Every Month
- Check the furnace / air conditioner filter and replace it when it looks gray (every 1 to 3 months depending on the filter, pets and season).
- Press the test button on GFCI outlets in kitchens, baths, the garage and outdoors.
- Look under sinks and around the water heater, toilets and washing machine for drips or damp spots.
- Run water and flush toilets in any bathroom you rarely use, so drain traps don't dry out and let sewer smell in.
- Top up water softener salt if you have one.
Spring (March to May): Recover From Winter, Get Ready for Rain
- Clean the gutters and downspouts and make sure downspouts carry water several feet away from the foundation.
- Test the sump pump by pouring a bucket of water into the pit, before the spring storms arrive. See our guide: nesterfy.com/articles/first-time-buyer/sump-pumps-in-ohio
- Walk the outside of the house: look for missing or lifted shingles, cracked siding, peeling paint, and gaps around windows, doors and where pipes enter the wall.
- Check that the soil slopes away from the foundation and fill any low spots where water collects.
- Have the air conditioner serviced before the first hot week, and clear leaves and debris from around the outdoor unit.
- Turn the outdoor faucets back on and check them for leaks; a pipe that froze in winter often only leaks once you use it.
- Look in the basement and crawl space for new damp spots, stains or white chalky residue on the walls after the thaw.
Summer (June to August): Humidity, Pests and Outdoor Work
- Keep basement humidity around 50% or lower with a dehumidifier, and empty or drain it regularly; damp basements grow mold.
- Inspect and clean the deck or patio, and re-seal wood decks every few years.
- Trim trees and shrubs back from the roof, siding and the AC unit.
- Watch for signs of termites, carpenter ants, wasps and mice; seal entry points before fall.
- Clean the dryer vent duct all the way to the outside, not just the lint trap. Clogged dryer vents are a common cause of house fires.
- Check window and door screens and repair tears before mosquito season.
Fall (September to November): The Most Important Season
In Ohio, fall maintenance does the most to prevent winter damage. If you only do one season well, make it this one.
- Have the furnace or boiler serviced and test the carbon monoxide detectors.
- Clean the gutters again after the leaves have fallen.
- Disconnect garden hoses, shut off the inside valve to each outdoor faucet if you have one, and drain the line. Blow out the irrigation system.
- Caulk and weatherstrip gaps around windows and doors to keep heat in.
- Have the chimney inspected and swept if you burn wood.
- Reverse ceiling fans to run clockwise on low, pushing warm air down.
- Test the sump pump once more and make sure the discharge line outside can't freeze or get buried under leaves.
- Stock up for winter: ice melt, a working snow shovel, furnace filters.
Winter (December to February): Prevent Frozen Pipes and Ice Dams
- Keep the heat at 55°F or higher, even when you travel, and open cabinet doors under sinks on outside walls during deep cold snaps.
- Know where the main water shut-off is, and make sure everyone in the house does too. A burst pipe can release hundreds of gallons an hour.
- Watch for icicles and ice building up along the roof edge; ice dams are usually a sign of heat escaping into the attic.
- Keep snow cleared from the furnace and water heater exhaust vents and from the gas meter.
- Test for radon. Winter, with windows closed, is a good time, and many Ohio areas have elevated radon levels.
- Check the attic after big storms for frost or wet insulation.
Once a Year
- Flush the water heater to clear sediment, and check its pressure relief valve.
- Replace smoke and CO detector batteries (or use 10-year sealed units), and replace detectors older than about 10 years.
- Have someone look at the roof, especially after a hailstorm or very high winds.
- Clean refrigerator coils and the range hood filter.
- Check caulk around tubs, showers and sinks and re-caulk where it has cracked or pulled away.
- Walk the house with your homeowners insurance policy in hand and make sure your coverage, including water backup coverage, still fits.
How Long the Big Systems Usually Last
Knowing roughly where each system is in its life lets you save for a replacement instead of being surprised by one. These are typical ranges; quality, installation and maintenance move them a lot.
| System | Typical lifespan | Plan for |
|---|---|---|
| Asphalt shingle roof | 20–30 years | Inspect after big storms; replace before leaks start |
| Furnace | 15–20 years | Annual service; budget once it passes 15 |
| Central air conditioner | 12–15 years | Annual service; replace with the furnace when practical |
| Tank water heater | 8–12 years | Annual flush; rust or leaks at the base mean it's time |
| Sump pump | 7–10 years | Test every season; add a battery backup |
| Exterior paint | 5–10 years | Touch up early to protect the wood |
| Deck sealant | 2–3 years | Re-seal before the wood turns gray and splinters |
Write down the install date of every major system, plus every service visit and repair, in one notebook or a shared spreadsheet, and keep receipts. It helps you plan, it helps contractors diagnose problems, and when you sell, a buyer who sees a maintenance history trusts the house more.
Do a few minutes of checks every month, spend a weekend each spring and fall, and pay most attention in the fall, before freezing weather. Budget 1% to 2% of your home's value each year, and keep a record of every system's age so replacements are planned rather than emergencies.
