Pressure washing uses high-pressure water to blast away dirt, grime, and moss. Soft washing uses lower water pressure combined with cleaning solutions to kill algae, mold, and mildew at the source. Soft washing is recommended for house siding, roofing, and painted surfaces where high pressure can cause damage. Hard surfaces like concrete and brick can typically withstand higher pressure.
Most homes in Calga benefit from an exterior wash every one to two years, particularly on surfaces that accumulate organic growth such as algae, mold, and lichen in Calga's humid seasons. Driveways and walkways may need attention more frequently. Regular washing protects your surfaces, maintains curb appeal, and extends the life of paint and finishes.
Spring is the most popular time for exterior washing in Calga, as winter salt and debris can be removed before painting or staining season. Fall washing prepares surfaces for winter. Most pressure washing should be done when temperatures are above 5 degrees Celsius to avoid water freezing in crevices. Avoid washing on windy days that scatter the cleaning solution.
Ask whether they use pressure or soft-wash methods and why they recommend one over the other for your specific surfaces. Confirm that their equipment and chemical use is appropriate for your siding type, as some materials are easily damaged by incorrect technique. Ask whether they carry liability insurance and whether the quote covers all targeted surfaces in full.
