10 Annual Home Maintenance Tasks Most Homeowners Forget

Most of us are pretty good at keeping the house tidy week to week, but there are a bunch of maintenance jobs that really should happen once a year and almost never do. Letting these slide does not just make your home look tired - it can lead to genuinely expensive repairs down the track, and some of these issues can even affect your insurance cover. Here are ten things worth putting in the calendar.

Gutters and Downpipes

Cleaning gutters is nobody's idea of a good Saturday, but blocked gutters are one of the most common causes of water damage to New Zealand homes. When water cannot drain properly, it backs up under your roofing iron or tiles, runs down interior walls, and rots the fascia boards. In leafy suburbs you might need to do this twice a year - once in autumn after the leaves drop and again in spring. If you are not comfortable on a ladder, plenty of local operators will do it for $150 to $300 depending on the size of your home. That is a fraction of what you will pay to fix water damage to your ceiling or walls.

Dryer Vents and Rangehood Filters

Lint builds up in your dryer vent over time and it is surprisingly flammable. A clogged vent also makes your dryer work harder, pushing up power bills and shortening the machine's life. Pull the vent hose off the back of the dryer, clear out the lint, and check the external flap opens and closes freely. While you are at it, give your rangehood filters a soak in hot soapy water - greasy filters do almost nothing and just recirculate cooking fumes through the kitchen.

Fire Safety Gear

Fire and Emergency New Zealand recommend testing your smoke alarms when the clocks change for daylight saving, which gives you a handy twice-yearly reminder. Press the test button on each alarm and replace the batteries if the beep sounds weak. Alarms older than ten years should be replaced entirely, as the sensors degrade. It is also worth having at least one fire extinguisher in the house and checking its expiry date annually. A decent dry powder extinguisher costs around $50 from a hardware store and could save your home.

Chimney and Flue Maintenance

Even if you only light the fire a handful of times each winter, creosote and soot build up in the flue and create a genuine fire risk. Birds also love nesting in unused chimneys over summer, and a blocked flue can push carbon monoxide back into your living space. Get a chimney sweep in before winter each year - expect to pay $120 to $200 depending on your area. If you have a wood burner rather than an open fire, the sweep can also check the door seals and baffle plate while they are there.

Water Pipes and Hidden Leaks

A slow leak under your kitchen sink or behind the washing machine can go unnoticed for months, quietly rotting your cabinetry and subfloor. Once a year, get down on your hands and knees and check under every sink, around the hot water cylinder, behind the dishwasher, and near the washing machine connections. Look for dampness, discolouration, mould, or a musty smell. Catching a small drip now saves you from discovering a major problem when you come to sell and the building inspector flags it.

Outdoor Paths, Decks, and Steps

Moss and algae on concrete paths and timber decks are a genuine slip hazard, especially through the wetter months. A pressure washer makes quick work of this, or you can use a stiff broom and a moss-kill product from the hardware store. Pay particular attention to steps, where a fall is more likely to cause a serious injury. Timber decks also benefit from an annual coat of stain or oil to protect them from UV and moisture - it keeps the timber looking good and extends its life by years.

Insulation Check

If your home was built before 2000, there is a reasonable chance the insulation has settled, been disturbed, or been chewed through by rodents. Poke your head into the ceiling cavity with a torch once a year and check the insulation is still evenly distributed and in decent condition. Under the Healthy Homes standards, rental properties must meet minimum insulation requirements, but even owner-occupiers benefit from keeping their insulation up to scratch. Topping up ceiling insulation is one of the cheapest energy efficiency upgrades you can make, and it pays for itself within a few years through lower heating bills.

Garage and Storage Clear-Out

The garage has a way of accumulating junk that you will never use again. An annual clear-out keeps the space functional and can even put money back in your pocket - TradeMe and Facebook Marketplace make it easy to sell tools, sporting gear, and furniture you no longer need. Any funds you free up can go straight to your mortgage as a lump sum payment. Beyond the financial benefit, a tidy garage is safer, gives you proper access to your switchboard and hot water cylinder, and means you can actually park the car in there.

Electrical Safety

Old multiplugs, frayed extension leads, and electric blankets past their prime are a common cause of house fires in New Zealand. Check your extension cords for any discolouration, cracked casings, or exposed wire, and replace anything that looks dodgy. Electric blankets should be replaced every five years or so - the wiring degrades with use and folding. If you have not had a proper electrical inspection done and your home is more than 25 years old, it is worth getting an electrician to check the switchboard and wiring. An outdated switchboard without modern RCD protection is a safety risk and may also affect your insurance.

Putting It All Together

Rather than trying to tackle everything in one weekend, spread these jobs across a month or two. Pick a quiet weekend for the gutters, another for the outdoor clean, and so on. Some people find it helpful to set calendar reminders at the start of each season so the jobs do not pile up. The cost of staying on top of annual maintenance is modest - a few hundred dollars and some elbow grease - but the cost of ignoring it can run into the tens of thousands when problems compound. Your home is almost certainly your biggest asset, so treat it like one.
