Why gutters leak
Most gutter leaks in Sydney come from one of five places: a joint where two lengths overlap, an internal or external corner, a stop end, the outlet where the gutter meets the downpipe, or a rust hole in the sole of the gutter. Sealant dries out and cracks after years of sun, and each hot day and cool night moves the metal a little further.
The other common cause is not a hole at all. If a gutter has lost its fall, water pools instead of draining, finds the lowest point and runs over the back edge onto the fascia and eaves lining. That looks like a leak from below but needs a different fix.
How we repair a leaking gutter
A lasting repair means taking the joint apart, cleaning back to bare metal, re-riveting and sealing with a roof-grade neutral-cure silicone. Running a bead over the top of old sealant rarely lasts a season. Where the leak is caused by poor fall we reset the brackets so the gutter drains fully, and where the metal itself has perished we cut out and replace that section.
Every repair is tested with running water before we pack up, and you get photos of what was found and what was done.
When a repair is not enough
If rust shows in several places along the same run, or the gutter has been patched repeatedly, the honest advice is usually to replace that run. We will show you why, and price both options where a repair is still viable. See gutter replacement and our repair or replace guide.

Leaking gutter repair: common questions
Can a leaking gutter joint be repaired, or does the gutter need replacing?
A leaking joint in an otherwise sound gutter can almost always be repaired. The joint is separated, cleaned, re-riveted and resealed. Replacement is only needed when the metal around the joint has rusted through or the same run has multiple failures.
Why does my gutter leak from behind?
Water coming from behind the gutter usually means the gutter is blocked or has lost its fall so water overtops the back edge, or the roof sheeting or tiles do not overhang the gutter far enough. A missing or damaged eaves flashing can also let water track back along the underside of the roof.
How much does it cost to fix a leaking gutter in Sydney?
A straightforward joint or corner reseal typically costs $150 – $350. Replacing a leaking section runs $350 – $800 depending on length, profile and height. Every job is quoted as a fixed price first.
Is silicone a permanent fix for a leaking gutter?
Only when it is applied properly. Sealant needs clean, dry, bare metal and a mechanically fixed joint underneath it. Silicone smeared over an old, dirty joint usually fails within months.
