Home Maintenance: A Practical Guide to Keeping Your House in Good Shape

You finally finish cleaning the bathroom. You're admiring your work.And that's when you notice the faucet is dripping, the caulk around the tub has pulled away, the refrigerator is making a noise you've never heard before and something on the roof looks… different.

That's homeownership. Homes are wonderfully demanding things.The good news: small problems are cheap to fix when you catch them early. All it takes is a simple system.

Check things regularly, handle the basic upkeep, know which jobs you can do yourself, know when to call a pro and spread the yearly chores across twelve months instead of trying to do them all one weekend in March.

Preventive Maintenance Is Cheaper Than Repair

A five-minute look under the sink costs nothing. A slow leak that rots the cabinet floor costs a lot. Preventive maintenance just means catching things while they're still small. Focus on:

•      Plumbing leaks

•      Signs of water damage

•      The roof and exterior

•      Heating and cooling

•      Appliances

•      Caulk and grout

•      Electrical outlets and switches

•      Doors and windows

•      Signs of pests

•      New or unusual sounds

That last one matters more than you'd think. Houses usually whisper before they yell. Listen before it starts shouting.

Build a Basic Home Toolkit

You don't need a garage full of power tools. A small kit handles most minor household jobs:

•      Screwdrivers (flathead and Phillips)

•      Hammer

•      Pliers

•      Adjustable wrench

•      Tape measure

•      Utility knife

•      Level

•      Flashlight

•      Cordless drill with bits

•      Basic nails, screws and wall anchors

•      Safety glasses and work gloves

Buy specialty tools when you actually need them. A household toolkit is supposed to save money, not become another collecting hobby.

Do a Monthly Home Check

You don't need to inspect every inch of the house every month. You just need to notice what's changed. Once a month, walk through and ask:

•      Any leaks or drips?

•      Anything loose, wobbly or broken?

•      New cracks?

•      Slow drains?

•      Doors or windows sticking?

•      Caulk pulling away?

•      Appliances acting differently?

•      Damp spots, musty smells or condensation?

•      Unusual noises?

•      Droppings, trails or other signs of pests?

The better you know how your house normally looks, sounds and smells, the faster you'll spot trouble.

Test Your Safety Equipment

This is the part of home maintenance you really can't skip.

•      Smoke alarms: Test them monthly by pressing the test button. Replace standard batteries once a year, and replace the whole alarm every 10 years. Look for the manufacture date on the back.

•      Carbon monoxide alarms: If you have gas appliances, a fireplace or an attached garage, you need CO alarms on every level and outside sleeping areas. Test them monthly and replace them by the date printed on the alarm, usually 7 to 10 years.

•      Fire extinguisher: Keep one in the kitchen. Check the pressure gauge monthly. If the needle isn't in the green, replace it.

•      GFCI outlets: These are the outlets with "Test" and "Reset" buttons, near water in kitchens, bathrooms, the garage and outdoors. Press "Test" monthly. The power should cut off. Press "Reset" to restore it.

And if you ever smell gas (that rotten-egg smell), don't flip any switches or light anything. Get everyone out, then call your gas company or 911 from outside.

Plumbing Maintenance

Water is the most expensive thing in your house to ignore. A slow drip under the sink can quietly swell cabinets, grow mold and turn a $10 fix into a $10,000 one. Keep an eye on:

•      Faucets

•      Toilets (a toilet that runs on its own is leaking)

•      Plumbing under sinks

•      Supply lines

•      Drains

•      The water heater

•      Dishwasher connections

•      Washing machine hoses (replace rubber hoses every five years, or upgrade to braided stainless steel)

•      Refrigerator water lines

•      Maintain the Water Heater

Check around the base for rust or moisture. Most manufacturers recommend draining a few gallons from the tank once a year to flush out sediment. Follow your owner's manual, and if the tank is leaking or more than 10 to 12 years old, start planning for a replacement before it plans one for you.

Prevent Clogged Drains

A slow drain is much easier to fix than a fully blocked one. Use drain strainers, keep grease out of the kitchen sink, and don't treat the toilet like a trash can. (Yes, "flushable" wipes too.)

Kitchen Maintenance

The kitchen has more appliances and water connections than any other room, so give it a little extra attention:

•      Refrigerator

•      Dishwasher (clean the filter monthly)

•      Garbage disposal

•      Range and oven

•      Sink plumbing

•      Faucets

•      Range hood filter (degrease it every month or two)

•      Cabinets near water lines

If an appliance starts leaking, making new noises or not working as well as it used to, deal with it now. It won't fix itself.

Maintain the Refrigerator

Vacuum the condenser coils, either behind the fridge or behind the kick plate at the bottom, every 6 to 12 months. Wipe the door seals, and check them by closing the door on a dollar bill. If it slides out easily, the seal is leaking cold air. Keep the vents inside clear so air can circulate.

Refrigerator Maintenance Tips →

Maintain the Garbage Disposal

Run cold water while it's on, and feed it a little at a time. It's a disposal, not a wood chipper. Keep out grease, bones, fruit pits, coffee grounds and fibrous foods like celery and corn husks.

Maintaining Your Garbage Disposal →

Laundry Room Maintenance

Clean the dryer's lint screen after every load. Have the dryer vent duct cleaned out at least once a year. Lint buildup is a leading cause of dryer fires, and a clogged vent makes every load take longer, too.

If clothes are taking more than one cycle to dry, or the outside vent flap barely moves when the dryer's running, the vent is probably clogged.

While you're there, check the washer hoses for bulges or cracks.

Heating and Cooling Maintenance

Your heating and cooling system is one of the most expensive things in your house to replace, and one of the cheapest to maintain.

•      Check the furnace or AC filter monthly, and replace it every 1 to 3 months. Change it more often if you have pets or allergies.

•      Keep vents and returns clear of furniture and rugs.

•      Keep the outdoor unit clear of leaves, weeds and debris, with about two feet of open space around it.

•      Listen for new noises.

•      Notice if some rooms aren't heating or cooling the way they used to.

•      Schedule professional service once a year: the furnace in the fall and the AC in the spring.

Tip: write the filter size on the furnace with a marker. Future You will be grateful.

Save Energy Through Maintenance

A well-maintained house uses less energy. Start with:

•      Clean HVAC filters

•      Weatherstripping and caulk around doors and windows

•      Thermostat settings (a programmable or smart thermostat helps)

•      The water heater temperature (120°F is plenty for most homes)

•      LED lighting

•      How you use your appliances

•      Attic insulation, if you can see the tops of the floor joists

Fireplace Maintenance and Safety

A cozy fire is lovely. It's still a fire inside your house.

Before each burning season, check for:

•      Cracks in the firebox or chimney

•      Damaged or missing parts

•      Soot or creosote buildup

•      Doors and screens that don't close properly

•      Smoke drifting into the room instead of up the chimney

Have a certified chimney sweep inspect your chimney once a year, even if you don't use it much. Birds, squirrels and creosote don't care how often you light a fire.

Gas fireplaces need an annual check, too. And make sure you have a working carbon monoxide alarm nearby.

Walls, Paint and Small Repairs

Nail holes and small dents are easy DIY jobs. A little spackle, a little sanding, a little touch-up paint, and you're done.

But cracks that run diagonally from the corners of doors or windows, get wider over time, or show up with stains or bulging can point to structural, plumbing or moisture problems. Find the cause before you cover it up. Paint is very good at hiding things. It isn't especially good at fixing them.

While you're at it, re-caulk any gaps around tubs, showers and sinks before water sneaks behind them.

Exterior Home Maintenance

The outside of your house takes a beating from sun, wind, rain and the occasional wayward baseball. Walk around it twice a year, and after any big storm, and check:

•      The roof (use binoculars from the ground, not a ladder)

•      Gutters

•      Siding

•      Exterior paint

•      Windows

•      Doors

•      The foundation

•      Drainage

•      Walkways

•      Decks and patios

Fix problems before water finds its way in. It always does.

Home Repairs You Can Do Yourself → 

Gutters and Drainage

Water should move away from the house. Keep your gutters and downspouts working so it does. Clean the gutters at least twice a year, in late spring and fall, and more often if you have a lot of trees. Watch for:

•      Overflowing gutters

•      Loose or sagging sections

•      Clogs

•      Water pooling near the foundation

•      Downspouts that dump water right next to the house (extend them at least 4 to 6 feet out)

Drainage problems are sneaky. They don't look like much until you have a wet basement.

Pest Problems

The occasional spider is part of life. An infestation is a maintenance problem. Watch for:

•      Ant trails

•      Wasp nests

•      Mouse droppings or chewed packaging

•      Mud tubes on the foundation (a sign of termites)

•      Damaged wood

•      Repeated activity in the same spot

Seal gaps around pipes, doors and windows. Fix leaks, since pests love water too. Store food in sealed containers. For termites, rodents or anything that keeps coming back, call a pro.

Know Which Repairs Need a Professional

DIY is great until it isn't. Leave these to the pros:

•      Electrical work beyond changing a light bulb or switch plate

•      Anything involving gas lines

•      Structural problems

•      Major roof work

•      Significant plumbing repairs

•      HVAC repairs

•      Mold larger than about 10 square feet, or any water damage you can't trace to its source

•      Anything that needs a permit

Here's a good rule: if a mistake could cause a fire, a flood, structural damage or an injury, a confident online video isn't enough.

Homeowners' Expenses You Shouldn't Skimp On

Putting off important repairs almost always costs more later. Spend the money first on:

•      Water leaks and water getting in

•      Electrical safety

•      Structural problems

•      Heating or cooling failures in extreme weather

•      Plumbing leaks

•      Roof damage

•      Smoke and carbon monoxide alarms

The new backsplash can wait.

Create a Home Maintenance File

Keep everything about your house in one place, paper or digital:

•      Appliance manuals

•      Warranties

•      Repair receipts

•      Contractor and repair contacts

•      Paint colors

•      Filter sizes

•      Model and serial numbers

•      Dates of major maintenance (roof, water heater, HVAC service)

Then, the next time something breaks, you'll have the model number without crawling around the utility closet holding your phone flashlight between your teeth.
