High-Pressure Washing

Pressure washing is easy to do badly, and the damage is permanent. Too much pressure strips the sand out of block paving, stripes poured concrete and blows the grout out of a porcelain terrace — all in the time it takes to walk one pass.

How we approach high-pressure washing.

Pressure, nozzle, distance and dwell are set per surface, and a rotary surface cleaner is used wherever an even finish matters more than reach — that is what stops the tiger-striping you see on half the driveways in Dubai. Interlock and block paving, exposed aggregate, poured concrete, porcelain terraces, natural stone, timber and composite decking each take a different setting, and soft render and old grout often take a chemical treatment at low pressure instead.

Oil, tyre rubber and algae need chemistry before water. A degreaser at proper dwell time lifts what pressure alone only polishes, and pool surrounds get a treatment that kills the algae rather than moving it to the drain. Where joints have washed out of block paving we re-sand them as part of the job, because cleaning interlock without re-sanding leaves the blocks loose and the next rain takes the rest.

Water is managed as carefully as pressure: run-off is directed to gullies rather than into the villa, and the drains and channels are cleared while the surface is still wet. Where a surface has already been damaged by a previous contractor — striped concrete, blown grout, eroded render — we will tell you what can be evened out and what needs re-grouting or resurfacing, and quote it separately.

Questions

Answered plainly.

Yes, at the right setting. Soft stone, old grout and timber take a lower pressure with a surface cleaner, and sometimes a chemical treatment does more of the work than water. We test an inconspicuous area first.

Yes, where the joints have washed out. Cleaning interlock without re-sanding leaves the blocks loose, so the two are quoted together rather than one now and a problem later.

Usually substantially, rarely perfectly. Old oil penetrates porous concrete, and degreasing plus poulticing lifts most of it. We set that expectation at survey rather than after the job.
