Pressure Washing in City of Westminster

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.

A single driveway or small patio takes 1-3 hours. A full house exterior typically takes half a day to a full day depending on size, number of storeys, and how much pre-treatment the surfaces need. Add drying time of a few hours before you walk on sealed or treated surfaces.

Most residential pros use your outdoor tap and, for electric machines, an outdoor socket. Petrol-powered machines only need water. Some companies carry water tanks for properties without an accessible tap — ask in advance, as tank supply can add to the price. Water usage for a typical driveway job is modest, roughly comparable to a few loads of laundry per hour of cleaning.

High-pressure washing damages most roof coverings — it strips granules from asphalt shingles, cracks and dislodges tiles, and can force water under the covering. Roof cleaning should be done by soft washing or manual moss removal plus a biocide treatment. If a company proposes blasting your roof at full pressure, choose someone else.

Driveway cleaning in City of Westminster is usually priced by area and condition. A standard single-car driveway sits at the bottom of the local range; a large or heavily stained double driveway with weed growth and oil marks can cost two to three times more. Ask whether resealing or re-sanding block paving joints is included — that is often a separate line item.

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.

UK guides put driveway cleaning at roughly £8.50-£15.50 per m². A single-car drive (up to 20m²) can be £40-£100, a standard two-car drive £100-£250, and large drives £250-£500. Resealing after cleaning adds £100-£200 to a medium drive.

Yes, but the jointing sand gets blasted out along with the grime, so the job is only complete once the joints are re-sanded (kiln-dried sand) and ideally sealed. If a quote doesn't mention re-sanding, the paving will loosen and weeds will return faster.
