Spring is the natural time for a deeper reset after winter, carpets and upholstery that have seen more indoor time and closed windows benefit from a steam clean, while exteriors often show accumulated grime from winter weather that's worth addressing with pressure washing once things dry out.
Summer suits exterior-focused work well, pressure washing dries fast in warmer weather and outdoor entertaining areas get more use, making it a practical time to tackle decking, driveways and outdoor furniture areas before they're in heavy seasonal use.
Autumn and winter shift focus indoors, sanitising ahead of flu season, addressing any mould that's developed in damp, shaded exterior areas over a wet period, and keeping high-touch surfaces sanitised as more time is spent indoors together as a household.
