Hard Surface Services in Dandenong

Hard Surface Services in Dandenong: Local Conditions

Dandenong's commercial and industrial properties generate a consistent and distinct category of hard-surface work that differs from residential pressure cleaning elsewhere in our service area. The car parks, loading dock aprons, bin bays and entry paths on industrial land around the South Dandenong estate accumulate a combination of oil-staining from vehicle leakage, fertiliser and chemical residue from garden maintenance, and organic growth from water pooling in low spots. We use a Kranzle 1000-PSI surface cleaner for the flat concrete areas. It's faster than a lance on large surfaces and doesn't leave the fan-pattern striping that shows up on grey aggregate. Tougher oil staining on concrete gets a pre-treatment with an alkaline degreaser left for 15 minutes before the hot wash. Strata properties off Cheltenham Road and Princes Highway have common area footpaths and entry pavements that are almost always in a partial state of moss and algae colonisation by mid-winter. The concrete gets shaded by building overhangs and the clay sub-base under pavers holds enough moisture to keep biological growth active year-round. We schedule the hard-surface rotation on strata contracts for late October or November, once the worst of the winter biological growth has peaked and before the summer dry sets in. Treated surfaces stay cleaner for longer when they get a dry period to consolidate. Timber decking on residential properties is also a regular request in the older parts of the suburb; we use a low-pressure wide fan on treated pine and hardwood to avoid raising the grain, and apply a post-clean inspection to identify any boards that need replacement before the next wet season.
