Most gutter problems start small: a drip at a join, a rust spot, a corner that overflows. Some can be repaired and will last for years. Others are the first visible sign of a gutter that is failing along its whole length, and repairing those just moves the leak to the next weak spot. Here is how we tell the difference on a quote.
Signs your gutters need replacing
- Rust that has eaten through the metal, or pitting along the bottom of the gutter.
- Water that sits in the gutter after rain has stopped, because the run has sagged or has no fall.
- Several joins on the same run leaking, even after resealing.
- Brackets that are rusted, broken or pulling out of the fascia.
- Gutters that overflow in normal rain because they are too small for the roof area they drain.
- Rotten or soft fascia boards behind the gutter, which mean the gutter has to come off to fix the fault properly.
When is a repair enough?
If the metal is sound and the problem is local, a repair is the right call. That covers a single leaking join that can be cleaned and resealed, a loose bracket, a dented section, or a corner that needs a new piece. Refalling a run, which means adjusting the brackets so water flows to the outlet, can also bring an otherwise good gutter back into working order.
Can you replace part of a gutter?
Yes. Gutters are made in lengths, so one damaged length can be cut out and replaced while the rest stays. It works well when the damage is limited, for example under one tree or beside a downpipe that overflowed. The catch is matching. Older profiles are not always made any more, and new steel joined to old steel can leave a visible change in colour and a join that ages differently. When most of a run is near the end of its life, replacing the whole run is usually better value.
If more than one section of the same run is failing, replace the run. Patching one section at a time usually costs more over a few years.
What happens when gutters are replaced?
- The old gutters and brackets are removed.
- The fall is set so every section drains to an outlet.
- New brackets go in at the right spacing for the gutter and the roof.
- New gutters are fitted with sealed joins, stop ends and outlets.
- Downpipes are checked, and replaced or added where the roof needs more drainage.
- Overflow points are added where an overflow could otherwise get inside.
Does the material matter near the coast?
It does. Salt air from the eastern beaches, the harbour and Manly speeds up corrosion, so the steel finish, the fixings and the mix of metals all matter. Using the wrong fixings, or joining incompatible metals, can make new gutters rust early. Ask any quote to say what finish and fixings it uses, and why, for a house close to the water.
Our gutter repairs and replacement service covers repairs, part runs and full replacements, including box gutters on terraces and strata buildings. Our metal roof repairs page explains how we handle coastal corrosion.
