Most home maintenance does not fail dramatically. It drips, it slows, it rattles, and then one Sunday evening the boiler has dropped to zero and the shower runs cold. An hour once a month, walking the house in the same order every time, catches those small drifts while they are still cheap and quick to sort out. The checklist below suits a typical UK home, whether you own it or rent it. If you rent, carry out the simple checks anyway and report anything needing a qualified trade to your landlord or letting agent in writing, so there is a record.

Start at the front door

The entrance takes more punishment than any other part of the house, so it is a sensible place to begin. Work from the outside in, then move along the hall.

• Hinges and lock: listen for squeaks and apply a drop of light oil. Try the lock with the key and check the handle does not feel loose.
• Draughts: run a hand around the frame. A worn brush seal or a cracked letterbox flap is a cheap replacement and makes an immediate difference in winter.
• Doormat and shoe zone: shake or vacuum the mat, and clear the pile of shoes and bags that tends to grow by the door. A shallow tray for wet boots saves the flooring.
• Hallway light: dust the shade or fitting. A film of dust can noticeably dull the light in a narrow space.

The kitchen: where most leaks begin

Water, heat and grease make the kitchen the busiest room in the house for maintenance. Ten minutes here each month pays for itself.

Drains and plugholes

Fill the sink with hot — not boiling — water and let it run through. If it drains slowly, lift out the plug and clear the trap of hair and food debris. A sink strainer is the simplest way to stop the problem returning. For the waste disposal point, and for bathroom plugholes, a handful of bicarbonate of soda followed by a slow pour of hot water is a common household routine. If water backs up in more than one outlet, that points to a shared blockage: stop pouring chemicals down and call a plumber.

Appliances and filters

Wipe the door seals on the fridge and check the fridge is not set so cold that vegetables freeze. Wash the metal grease filter from the cooker hood by hand or in the dishwasher. Pull out the washing machine filter if it is accessible, and run an empty hot cycle to freshen the drum. Clear the tumble dryer lint filter and check the flexible hose at the back for kinks or crushed sections. Finally, open the cupboard under the sink with a torch and look for damp patches or a staining ring on the shelf.

Bathroom and utility room

Bathrooms combine water, warmth and poor air movement, which is exactly the mix that encourages mould.

Drains, seals and ventilation

Run the shower and the basin for a minute, then check under the bath and behind the toilet for damp. Look at the silicone line where the bath meets the wall: if it has lifted or gone black, it needs replacing. Descale the shower head by soaking it in a bag of white vinegar tied around it, then rinse. Test the extractor fan by holding a piece of tissue near the grille — it should be pulled towards the fan. If it barely moves, the fan or ducting needs attention, and the room will need to be aired by opening a window after showers in the meantime.

Alarms, boiler and heating

These are the checks with the greatest safety value, so do them before the more cosmetic jobs.

1. Smoke alarms: press and hold the test button until it sounds, then vacuum the vents with a brush attachment. Replace batteries where the unit is not sealed, and note any intermittent chirp. Fit and test a carbon monoxide alarm wherever there is a fuel-burning appliance or an open fire.
2. Boiler pressure: read the gauge with the heating off. Many sealed systems sit somewhere around 1 to 1.5 bar when cold, but your own manual is the authority. If it is low, top up using the filling loop as described in the manual and check again after a day. If it keeps dropping, that is a job for a Gas Safe registered engineer.
3. Radiators: feel across each radiator from top to bottom. Cold at the top and warm at the bottom usually means trapped air. Bleed it with a radiator key, holding a cloth underneath, and close the valve as soon as water appears.

Book a boiler service once a year rather than waiting for a fault. Never open the casing of a gas appliance yourself, and treat any smell of gas as an emergency: turn the supply off if you can reach it, open windows, and call the national gas emergency line from outside the property.

Living rooms and bedrooms

Little to repair here, but plenty to keep on top of. Dust behind televisions, media units and routers, where fluff collects against warm surfaces. Check that plug leads are not pinched behind furniture, and that extension leads are not run under rugs. Look at window reveals and the corners of ceilings for grey patches or a musty smell, which suggest condensation rather than a leak. Keep trickle vents open rather than blocking them to stop draughts.

In bedrooms, rotate or turn mattresses where the manufacturer advises it, and wash pillows and duvet covers on the usual cycle. If the loft hatch is in a bedroom or landing, note whether the insulation has slipped or come away from the joists.

Outside, loft and garage

Even five minutes outdoors prevents expensive surprises. From the ground, look along the gutters for sagging sections and check downpipe outlets during rain — water pouring down the wall instead of into the drain means a blockage. Lift the grate on any outside gulley, scoop out leaves and pour a bucket of water through to confirm it flows. Check the outside tap does not drip, and if the weather has turned cold, make sure any isolator is closed and the pipe drained. In the loft, look for daylight through the roof, damp patches on the timbers, and insulation that has been pushed over the eaves vents. In the garage or shed, stand cardboard and garden furniture off the floor so damp cannot creep up.

Turning the list into a habit

The whole walkthrough takes about an hour, and it works best when it is boring and identical each time. Put a repeating reminder in your phone for a date near the start of the month, and do the safety checks first while you are still fresh. Keep a small box of spares in one place — light bulbs, alarm batteries, silicone, a radiator key, a torch — so a found fault can be fixed on the spot rather than added to a list. Write down anything you cannot manage yourself, along with the date, and deal with it in the following week.

Some jobs sit firmly with the professionals: gas, mains electrics, anything involving the roof or ladders you are not confident on, and persistent damp. Everything else on this list is well within reach of a careful hour and a tidy cupboard of basics.
