Preparing For Your Exterior Clean

Our cleaning solutions can react negatively with freshly painted, varnished, lacquered or sealed surfaces that have cured for less than 6 weeks. This can lead to issues like delamination or peeling. Any wooden fixtures, including windows, blinds or decking, that have varnish or oil protection older than 18 months – particularly if exposed to direct sunlight – may react in a similar manner, potentially leading to stripping or discolouration. Please inform us before we commence work if any areas on your property fall into these categories, as we may need to avoid them. Brisbane Roof Cleaners is not liable for damage to freshly cured or inadequately protected older wooden surfaces if not notified prior.

Bare wooden fixtures such as doors, window frames and posts, or wooden deck areas that haven’t received a professionally applied new coat within the last 12 months, may be prone to bleeding or discolouration. Please notify our technician prior if you want these areas avoided; otherwise this will be at the owner’s risk.

Removing dirt and mould often reveals pre-existing oxidisation – a chalky, dull layer on painted surfaces that is a natural effect of UV exposure and weathering. Our cleaning process removes the grime, revealing the true condition underneath. Brisbane Roof Cleaners is not liable for existing oxidisation revealed by the cleaning process; it indicates the area is due for repainting.

Occasionally, internal paint that is not rated for external conditions is used on exterior areas. This can exacerbate cleaning effects, and we are not liable for adverse reactions where inappropriate paint has been used externally.

Some pre-existing stains such as rust, calcium, red earth or hard water marks may not be removed completely, and their removal can sometimes lead to minor paint loss or bleeding, especially on darker, sun-exposed surfaces.
