Pressure washing in Dulwich.

Show the paving and its planted edges.

A close-up of the dirt helps, but the wide view tells us how the job will work. Include the lawn, low planting, pots and any pond beside the paving. Mention whether leaves collect in one corner or water sits along the house wall.

Leaf marks, surface algae and black lichen spots may need different treatment. We look at the material and joints before choosing a method. More pressure is not a useful answer to every stubborn mark, and some staining may remain after a suitable clean.

An older front path needs a separate look.

Southwark’s conservation-area information covers Dulwich Village and Dulwich Wood. Check the council’s address maps if your proposed exterior work may affect a protected property or feature; the whole neighbourhood does not have one uniform status.

Show us decorative tiles, soft brick, old repairs and loose edges. A tiled entrance is assessed separately from modern patio slabs. Fragile historic fabric can need specialist care, which is outside a standard pressure-washing visit.

Southwark Council: conservation areas and address maps

Put the whole garden in one brief.

If the side path, patio and back steps all need attention, photograph each one and show how they connect. Include the route through the house where there is no outside access. List filled planters or heavy furniture before the quote.

We agree the cleaning boundary, preparation and any treatment in writing. Drying, joint repairs or re-sanding can mean the work takes more than a single visit. Tell us about a party or house viewing early so the programme can be discussed realistically.
