Your Ultimate 5 Steps Guide to Gutter Solutions and Services!

A complete gutter job runs in a fixed order: inspect, clean, repair, realign and, only when repair no longer holds, replace. Doing the steps in order stops you paying for a new gutter when a clean and a few brackets would have fixed the problem.

1. Inspect the gutters, downpipes and fascia for blockages, leaks and sagging.
2. Clean out debris and flush the system with a hose.
3. Repair minor leaks, cracked joints and loose fixings.
4. Realign any run that sags, pools or overflows.
5. Replace the system when damage is widespread or the fascia behind it has failed.

Start from the ground with a torch or binoculars and walk the whole roofline in daylight, then go up only if you need a closer look. Working at height is the real hazard here, so treat the ladder as seriously as the gutter.

• Blockages: leaves, twigs and moss packed along the run or at the outlet.
• Leaks: drips at joints, corners and seams, or staining on the wall below.
• Sagging: any section that dips, holds standing water after rain or pulls away from the fascia.
• Overflow marks: clean streaks or stained fascia where water has spilled over the edge.

Set the ladder on firm, level ground, keep your body between the rails, ask someone to foot it, and stay off the roof and the ladder in wet or windy weather. WorkSafe’s working-at-height guidance, linked at the end of this guide, sets out the safe approach.

Cleaning is the job most homeowners can do themselves, provided they can reach the gutter safely from a stable ladder or platform. You need gloves, a scoop or small trowel, a bucket and a garden hose.

1. Start beside a downpipe and scoop debris into the bucket, working away from the outlet.
2. Pull out blockages at each outlet by hand before you use water.
3. Flush the run with a hose, starting at the end furthest from the downpipe.
4. Watch the flow: water should move steadily to the outlet without pooling or spilling.
5. Bag the debris and put it in your green waste or compost rather than leaving it on the ground, where it washes back into the stormwater drain.

If the same gutter fills again within weeks, the cause is usually fall, an undersized outlet or overhanging trees rather than the cleaning itself.

Small, accessible faults are a reasonable DIY job: a weeping joint, a loose bracket or a small hole can often be sealed or re-fixed in an afternoon. Gutter sealant suits small joint leaks, and a stainless or galvanised screw suits a loose bracket.

Anything that involves a long run, a split corner, a rusted-through section or timber that is soft to the touch is a job for a professional. The repair service page explains what is involved, and how to fix a leaking gutter seam walks through the most common small repair. For repairs we do, see gutter repair in Auckland.

A gutter overflows or sags because water is not reaching the downpipe, so the fix is to restore a steady fall toward the outlet and secure the fixings. Check three things in order: the brackets, the fall and the fascia behind them.

• Brackets: tighten or replace loose and bent brackets so the gutter is supported along its length.
• Fall: run a hose into the high end and watch whether water travels to the outlet or stands in a section.
• Fascia: if the timber is soft, the brackets will not hold and the gutter will sag again, so the fascia has to be repaired first.

The order of fascia, soffit and gutter work matters. Fascia, soffit and gutter replacement: what comes first explains why.

Replace the gutter when repair keeps failing: widespread rust, split seams along several runs, a system that was never sized for the roof, or fascia damage that needs the whole run taken off anyway. Replacing early is usually cheaper than paying for repeated repairs.

The material you choose depends on the house and where it stands. This matches the options on our replacement page:

See our gutter replacement service for the options, and the cost calculator for a guide price before you ask for a quote.

The profile is the shape of the channel, and it affects both how the house looks and how much water the gutter carries. Choose one that suits the roofline and the roof area it drains.

• Quad (square-edged): a modern, angular look that suits contemporary fascias.
• Half-round: a rounded channel that suits villas and traditional homes.
• Box or internal gutters: built into the roof or concealed behind a parapet, so any overflow can spill into the building and the design needs more care.
• Seamless systems: formed in one piece along a run to reduce the number of joints that can leak.

Gutter guards are an optional extra that reduces how much debris enters the channel, although they still need checking and cleaning from time to time.

Call a professional when the job involves height, structure or a system you cannot see the whole of. These are the usual signs:

• Severe leaking, cracking or sagging along more than one run.
• A two-storey house, a steep roof or a gutter you cannot reach from a stable ladder.
• Rotten fascia or soffit, or water staining inside the ceiling.
• A complex roofline, valleys or an internal gutter system.

Choose an installer by asking what the quote includes, not only what it costs. Neighbours, friends and local reviews are a sensible starting point, and a written, itemised quote lets you compare like with like.

• Ask whether the quote includes a fascia inspection once the old gutter is off, and what happens if rot is found.
• Check what is included: removal of the old gutter, new brackets, downpipes, outlets and a water test.
• Ask which material and profile the price is for, and how long the work will take.
• Get the scope, price and timing in writing before work starts.

A quote that is much lower than the others often leaves something out, so ask what is missing before you say yes. Comparing quotes is easier when each one covers the same scope for your project.

Cost depends on the material, the length of the roofline, the number of storeys and how much fascia work is needed, so the sensible first step is a guide range and then a written quote. The cost calculator gives a guide range for cleaning, repair and replacement, and the written quote sets the final price.
