A Monthly Five-Minute Home Walkthrough

What would you notice if the cabinet under your bathroom sink had been damp for three weeks? Probably nothing, at least not until the cabinet floor swelled or a musty smell drifted into the hallway. Small problems in a house tend to stay quiet until they aren't, and catching them early has less to do with expertise than with looking regularly.

That's the idea behind a monthly walkthrough. Pick a day you already remember, like the first Saturday of the month or the day a regular bill goes out, and put five minutes on the calendar. Walk the same short route each time with your eyes, nose and ears switched on. It isn't a home inspection and won't replace one. It's a habit, and after a few months you'll know what normal looks, sounds and smells like in your house, so anything different will stand out.

Why a short monthly look works

Plenty of costly repairs start as something small. A water heater weeps at a fitting long before it leaks across the basement. A downspout that came loose during a storm quietly soaks the same corner of the foundation every time it rains. A toilet seal fails slowly, softening the subfloor a little at a time.

None of those take special skill to spot. They just take someone looking. A quick, regular walkthrough gives you a chance to catch problems while they're a fix-it-this-weekend item or a routine service call rather than an emergency.

The route below is loosely timed. Some months it'll take three minutes, some months ten. Don't worry about the clock; worry about looking at the same things each time.

Minute one: kitchen and bathrooms

Open the cabinet doors under every sink. Look and feel for dampness, stains, swollen particleboard or a musty smell. Glance at the shutoff valves and supply lines for drips or corrosion.

Look at the floor around each toilet. Soft spots, staining or a toilet that rocks can point to a leak at the wax seal. Check the caulk around tubs and showers for gaps where water could get behind the tile. Listen for a toilet that runs or refills on its own between uses.

In the kitchen, peek at the floor around the dishwasher for moisture, and every few months pull the refrigerator out if it has a water line. Press the test and reset buttons on the GFCI outlets near sinks. If one won't trip or won't reset, have an electrician take a look.

Minute two: the utility area

This is where the house keeps its working parts, so give it a slower look.

At the water heater, check the floor around the base for water or rust stains, and look at the end of the discharge pipe on the relief valve for drips. On a gas unit, look for scorch marks around the burner access. If you smell gas at any point, leave the house and call the gas utility from outside.

Check the HVAC filter. You don't have to change it every month, but a quick look tells you whether it's getting dirty faster than you expected. Make sure the area around the furnace and water heater is clear of boxes, paint cans and laundry.

Glance at washing machine hoses for bulges or cracks, and pour a little water into the sump pit every few months to confirm the pump runs.

Then look at the outside of the electrical panel, without opening it. Warmth, a burning smell, buzzing or scorch marks on the cover are reasons to call a licensed electrician right away. Don't remove the cover yourself.

Minute three: ceilings, walls, windows and detectors

Walk through the main rooms and look up. Brown rings or bubbled paint on a ceiling usually mean water from somewhere above: a bathroom, a roof leak, or condensation from ductwork or an attic unit. Note any new cracks in drywall, especially above doors and windows, and doors that suddenly stick or won't latch.

Check windows for fogging between the panes, which usually means a failed seal, and for water pooling on sills. Pay attention to new smells, like musty air in a closet or a faint electrical odor near an outlet or switch.

Press the test button on smoke and carbon monoxide detectors as you pass them. It takes a second each and confirms they have power.

Minutes four and five: a lap around the outside

Step outside and walk the perimeter. Look up at the gutters for sagging sections or plants growing out of them, and down at the downspouts to confirm they're attached and sending water away from the house. Look at the roof from the ground for anything missing or out of place, especially after a windy stretch.

Check the foundation for new cracks or wet spots, and look for mud tubes, droppings, gnaw marks or insect activity near the base of the walls. If you see signs of termites, rodents or other pests, a licensed pest control company can inspect, and they'll know the pesticide rules for your state.

Glance at the outdoor air conditioner or heat pump to make sure nothing is piled against it. Check that outdoor faucets aren't dripping, and in cold months, that no hoses are still attached. Finally, look at trees near the house for broken or dead limbs.

Your walkthrough card

Copy this list into your phone or tape it inside a utility closet door.

• Under every sink: dry, no stains, no musty smell
• Toilets: solid base, no running water between uses
• Tub and shower caulk: no gaps or cracks
• GFCI outlets: test and reset
• Water heater: dry base, no drips from the relief valve pipe
• HVAC filter: glance at it and note its color
• Furnace and water heater area: clear of clutter
• Washer hoses: no bulges or cracks
• Electrical panel: cool, quiet, no smell, cover closed
• Ceilings and walls: no new stains or cracks
• Smoke and carbon monoxide detectors: press test
• Gutters and downspouts: attached and draining away
• Foundation: no new cracks, dampness or pest signs
• Outdoor unit: clear of debris

Keep a simple log

A note on your phone works fine. Write the date and anything you noticed, even if it seems minor, and snap a photo of anything you want to compare next month. Over time, the log shows you which issues are stable and which are growing, and it gives a contractor useful history if you do need to call one.
