Pressure Washing in General Santos

Fresh oil mostly comes out with a degreaser pre-treatment plus hot-water pressure washing. Old oil that has soaked deep into concrete may only fade, not disappear — an honest pro will tell you this before quoting rather than promising full removal. Ask specifically whether stain treatment is included or extra.

Renting a machine costs a fraction of a pro visit, but consumer machines are slower, and the main risks are damage (etched concrete, stripped paint) and injury — a 3000+ PSI jet can cut skin. DIY makes sense for a small, flat concrete area. Hire a pro for two-storey walls, roofs, timber, render, or anything needing ladders or chemicals.

Move cars off the driveway, clear pots, furniture, and toys from the work area, close all windows and doors, and cover or flag anything fragile like garden lights. Point out hairline cracks, loose pointing, or flaking paint in advance — pros will work around known weak spots but cannot see them under grime.

Light rain is usually fine — surfaces are already wet. Pros avoid freezing temperatures (ice risk on cleaned surfaces and damaged equipment) and heavy storms. In hot dry regions, local water restrictions can limit or ban high-volume outdoor cleaning during drought periods, so check the current rules before booking.

Yes. Too much pressure or the wrong nozzle can etch concrete, blast mortar out of brick joints, splinter timber decking, strip paint, and force water behind siding or render. Roof tiles are especially vulnerable. Ask the pro what PSI and nozzle they plan to use per surface, and whether they soft wash delicate areas.

A crew with proper equipment typically charges ₱300-₱700 per hour or quotes per job: roughly ₱1,000-₱4,000 for a driveway and garage, ₱3,000-₱12,000 for a full house exterior depending on size. Metro Manila prices are the highest; provincial rates can be 30-40% lower.

The start of the dry season (December-January) gives the longest-lasting results. Washing during the wet season still works but mould and algae on shaded walls can return within 4-8 weeks unless an algaecide treatment is applied.
