How Often Should Fascias and Soffits Be Cleaned?

Fascias and soffits should ideally be cleaned every two to three years on most properties. In areas with significant tree coverage, north-facing aspects, or high humidity, annual cleaning may be needed to prevent heavy algae build-up. uPVC fascias are particularly prone to green algae growth, which if left unchecked will stain the surface permanently over time.

The build-up of green algae is not just a cosmetic issue. The biological growth holds moisture against the surface, which in the case of wooden fascias and soffits can accelerate rot and deterioration. For uPVC, prolonged algae coverage can permanently discolour the surface — making regular cleaning not just cosmetic but genuinely protective.

Combining fascia and soffit cleaning with your annual gutter clear is the most efficient approach. The gutter clearing crew is already working at height, so the additional cost of cleaning the fascias and soffits at the same time is relatively small. Many customers find the combined service transforms the appearance of their home's exterior.
