Blocked gutters are one of the most common and most preventable causes of home and building damage in Sydney. Sydney receives about 1,175 mm of rainfall per year, and when gutters can't handle that volume, water backs up quickly.
So, how often should your gutter be cleaned?
For most residential properties, at least twice per year is the minimum, but properties with heavy tree coverage may need cleaning every 2–3 months. Strata complexes and commercial buildings with large roof catchment areas generally warrant more frequent attention, and some insurers expect documented maintenance schedules as a condition of coverage.
Many home insurance policies include a clause that excludes damage that could have been prevented with regular maintenance. So, neglected gutters can cost you twice: once in repairs, and again when a claim is rejected.

Not every Sydney property has the same needs. These are the key factors to consider:
Clean gutters protect far more than the roof. If water enters the structure of your building, it can cause rotting, internal plaster damage, mould growth, and weaken structural integrity. Blocked gutters can also attract insects, rodents, and other pests, and home insurance policies won't cover damage caused by vermin.
For strata managers and building owners, the stakes are higher still. Water damage affecting multiple units, business interruption, and liability for tenant property can compound quickly from a single blocked downpipe.
Don't wait for the scheduled service if you notice:
A twice-yearly schedule usually means once in late autumn or early winter after most leaves have fallen, and once in late spring or early summer before storm season begins. This keeps gutters ready for Sydney's heaviest rainfall periods and reduces the risk of storm damage.
