Summer Home Maintenance Checklist for Kiwi Homeowners

As the days stretch out and the tui start their morning chorus a little earlier, it's a sure sign that summer's on its way. Before you break out the jandals and fire up the barbie, it's worth spending a weekend or two giving your home a once-over. A bit of effort now can save you headaches later — and means you'll actually get to enjoy the warm months instead of scrambling to fix things when they go wrong.

Here's our practical summer maintenance checklist, tailored for Kiwi homes and conditions.

Give Your Deck Some Love DIY

Your deck cops a hiding over winter. Rain, frost, and lack of sunshine can leave timber looking grey, slippery with algae, or starting to split. Give it a good sweep, then wash it down with a deck cleaner and a stiff broom or a low-pressure water blaster (go easy — you don't want to gouge the timber).

Once it's dry, check for any popped nails, loose boards, or soft spots that might indicate rot. If the wood looks thirsty, a fresh coat of deck oil or stain will protect it through the summer and keep it looking sharp.

If you've got structural issues — wobbly posts, rotting joists, or boards that feel spongy underfoot — it's best to get a professional in to assess the damage. Call a Tradie

Service Your Heat Pump

Your heat pump has been working overtime keeping you warm through winter, and it'll need to switch gears for cooling duties over summer. Pull out the filters and give them a good wash in warm soapy water — you'd be amazed how much dust and fluff builds up. Let them dry completely before popping them back in. DIY

While you're at it, wipe down the indoor unit and check that the outdoor unit isn't blocked by leaves, garden clippings, or overgrown plants. Good airflow makes a big difference to how efficiently it runs.

If your heat pump is making unusual noises, not heating or cooling properly, or hasn't had a professional service in a couple of years, book in a full service with a qualified technician. Call a Tradie

Check Outdoor Taps and Irrigation DIY

Outdoor taps and irrigation systems can take a battering over winter. Frost can crack fittings, washers can perish, and joints can work loose. Turn on each outdoor tap and let it run for a minute, checking for drips at the spout, the handle, and where the pipe meets the wall. Walk your irrigation lines and check sprinkler heads for leaks or damage.

Replacing a worn washer or tightening a fitting is a straightforward job. If you've got a persistent leak, a burst pipe, or anything involving your mains supply, get a registered plumber onto it. Call a Tradie

Clear Cobwebs and Check for Wasps DIY

Grab a long-handled broom or cobweb brush and work your way around the eaves, soffits, window frames, and doorways. Spiders love to set up shop in sheltered spots over winter, and their webs can make your place look neglected pretty quickly.

While you're up there, keep an eye out for the beginnings of wasp nests — they often start as small, papery grey structures tucked under eaves or in roof cavities. Early-season nests are small and much easier to deal with than a full-blown colony in February. For established nests, especially in hard-to-reach spots, don't take the risk. Call a Tradie

Inspect Window Seals and Weatherstripping DIY

Close each window and check the rubber seals and weatherstripping for cracks, gaps, or sections that have come away. Damaged seals let in draughts, moisture, and dust — and in summer, they'll let your cool air escape and warm air creep in. Run your hand around the edges of closed windows; if you can feel air movement, the seals need attention.

Replacing stick-on weatherstripping is a simple afternoon job. If your window seals are built into aluminium joinery and have failed, or if you're noticing condensation between double-glazed panes, you'll want a joinery specialist to take a look. Call a Tradie

Get Your BBQ Summer-Ready DIY

Nothing says Kiwi summer like a sizzling barbie, but dragging it out after months of neglect and hoping for the best isn't the way to go. Pull it apart as much as you can — remove the grill plates, burner covers, and drip tray. Soak the grates in hot soapy water and scrub them down. Clean out the firebox, check the gas hose for cracks or perishing, and give the burners a once-over to make sure the ports aren't blocked.

Do a test run before you've got a crowd of hungry mates waiting. Light it up, check for even flame across all burners, and make sure the igniter is sparking reliably.

Clean Your Rangehood Filters DIY

This one's easy to forget, but grease-clogged rangehood filters don't extract properly and can become a fire risk. Most mesh filters pop out and can be soaked in hot water with a good squirt of dishwashing liquid or a scoop of baking soda. Give them a scrub, rinse, dry, and clip them back in.

If your rangehood has carbon or charcoal filters, these can't be cleaned — they need replacing. Check your manual for the recommended timeframe.

Check Your Exterior Paint DIY

Walk around the outside of your house and look for any paint that's peeling, bubbling, flaking, or chalking. Pay close attention to the north and west-facing walls — they cop the most sun and weather. Window sills, fascia boards, and barge boards are common trouble spots.

Small patches of flaking paint can be sanded back, primed, and touched up on a dry day. If the damage is widespread, or if you suspect moisture is getting in behind the cladding, it's worth getting a professional painter or builder to assess what's going on. Call a Tradie

Freshen Up Shower Heads and Tap Aerators DIY

If your shower has lost its oomph or the kitchen tap is spraying sideways, mineral build-up is usually the culprit. Unscrew the shower head and soak it overnight in a bowl of white vinegar — same goes for tap aerators (those little mesh screens on the end of your taps). An old toothbrush works a treat for scrubbing out stubborn deposits. Rinse, reattach, and enjoy the difference.

Trim Trees and Vegetation

Over winter and spring, trees and shrubs have a habit of creeping closer to the house than you'd like. Branches rubbing on the roof or cladding can cause damage, and overhanging vegetation traps moisture and provides a highway for insects and pests.

Cut back anything that's touching or within a metre of the house. Trim hedges away from fences and paths, and clear any growth away from your outdoor heat pump unit. DIY for anything you can reach safely from the ground. For large trees or branches near power lines, always call in a qualified arborist. Call a Tradie

Clear Your Spouting and Downpipes

Spring might be over, but the tail end of leaf fall — plus all the blossoms and seed pods — can leave your gutters clogged. Blocked spouting causes water to overflow and run down your walls or pool around your foundations, which is a recipe for moisture problems.

If you can safely reach your spouting from a ladder, scoop out the debris by hand (gloves are a good idea) and flush the downpipes with a hose to check they're running clear. DIY For two-storey homes or steep rooflines, don't risk it — get someone who's set up to work safely at height. Call a Tradie

Test Your Outdoor Lighting DIY

Longer evenings mean more time outside, so make sure your outdoor lights are working properly. Check each fitting, replace any blown bulbs (consider switching to LEDs if you haven't already — they last ages and use next to nothing), and clean the covers so you're getting decent light output. Test any sensor or timer-controlled lights to make sure they're triggering correctly.

Replacing bulbs and cleaning fittings is straightforward. If you need new fittings installed, wiring extended, or anything involving the electrical supply, that's a job for a licensed sparky — no exceptions. Call a Tradie

Make It a Habit, Not a Hassle

You don't have to tackle everything in one go. Pick a couple of items each weekend and work through the list at your own pace. The goal isn't perfection — it's staying on top of things so small issues don't turn into big ones. Your home works hard for you year-round, and a little seasonal attention goes a long way.

Happy summer, and enjoy that deck once you've oiled it — you've earned it.
