Pressure washing in Merton.

Show us what happens after rain.

If water sits on the patio, include a photograph of it. Show the lowest point, nearby drains, air bricks and the doors into the house. A dry photograph helps us identify the paving; the wet one can reveal a practical problem that the clean alone will not solve.

Pressure washing is not a drainage repair. A blocked drain, poor falls or a sunken section may need separate investigation before cleaning is useful. Tell us about any previous overflow, and do not assume a road gully is an appropriate route for wash water. Runoff arrangements belong in the job plan.

A blocked road gully has a different reporting route.

Merton Council’s drain guidance distinguishes ordinary road gullies, Red Routes and sewers. It directs residents to the council for blocked or damaged gullies on other roads, to TfL for Red Route problems, and to Thames Water for sewer issues or overflowing manholes.

Use that guidance if the problem is beyond your property. For a private drain, explain the symptoms when you enquire and arrange appropriate investigation where needed. Our cleaning quote does not include sewer clearance or a repair unless a separate, suitable scope has been agreed.

Merton Council: report drain or sewer problems

Plan the paving and deck as different surfaces.

A rear garden can have porcelain by the kitchen, stone steps and timber further out. Send one photograph of each material. If a deck has a product name or care sheet, include it; the method for sound concrete is not a default for boards or delicate stone.

Tell us about nearby planting, ponds and places where children or pets need access. We agree the preparation and any temporary restrictions around the specific method. If treatments or joint work need drying time, the plan may extend beyond the washing day.
