Exterior cleaning challenges in Maidstone and the Medway towns

Maidstone and Medway throw up different problems: shaded, tree-covered roofs and soft ragstone around Maidstone and Bearsted; steep hillside streets, tight plots and damp estuary air in Chatham, Rochester, Gillingham and Strood. The right method depends on which of those you are dealing with.

Roof cleaning carried out from a powered access platform in Kent

We are based in Maidstone and work across the Medway towns every week. The same job — a mossy roof, an overflowing gutter, a green driveway — rarely looks the same in two places, because the housing, the trees and the ground all change as you move around the area.

These are the challenges we actually run into locally, and how we handle each one.

Shaded roofs and moss around Maidstone and Bearsted

Mature tree cover through Maidstone, and especially around Bearsted and Weavering, keeps rear roof slopes damp long after rain. That is exactly what moss needs, so shaded roofs here moss up noticeably faster than open ones.

We remove moss by hand and follow it with a biocide treatment. We never pressure wash a tiled roof — it strips concrete tiles and cracks older clay peg tiles, which are common on the Victorian terraces off Tonbridge Road.

Gutters full of leaf litter and roof debris

Where there are trees there are blocked gutters. In Bearsted, Weavering and the leafier parts of Maidstone, once a year is often not enough for runs sitting directly under branches.

In Gillingham and across Medway, moss washed off the roof ends up in the guttering too, which is why we clear gutters as part of every roof job. Gutters are cleared from the ground with vacuum poles, and you get before and after photographs.

Kentish ragstone and soft stone

Ragstone walls, steps and paths are all over Maidstone. The stone is soft, and high pressure opens up its face. We clean it at controlled pressure or softwash it depending on condition — and if a surface is better left alone, we say so.

Block paving on the newer Maidstone estates

Allington, Barming and Weavering have a lot of large block paved drives. Weeds and moss take hold in the joints, so we clean with a rotary head and re-sand with kiln-dried sand as standard.

Hillside access in Chatham and Strood

Chatham and Strood are built on hillsides, so pitch and access change street by street. Access is the first thing we assess on a Medway roof. Where a powered platform can be set up safely we work from it; where it cannot, we say so and quote the alternative.

Around Rochester High Street, tight plots often rule out scaffolding, so powered access is usually how we reach the roof.

Estuary air and green render in Gillingham and Medway

Damp air off the Medway estuary keeps algae going on render, cladding and painted walls, and on north-facing roof slopes. Render is softwashed with a treatment rather than pressure washed, because pressure damages it and forces water behind it.

Getting a price in Maidstone or Medway

Send a few photographs and the address and you will get a fixed written price back, usually the same day.

The short version

  • Tree cover around Maidstone and Bearsted means faster moss and more frequent gutter clearing.
  • Tiled roofs are cleaned by hand and treated — never pressure washed.
  • Ragstone and render need controlled pressure or softwashing, not blasting.
  • On Medway hillsides and tight Rochester plots, access is assessed before any quote.

Questions

Frequently asked

Do you cover both Maidstone and the Medway towns?

Yes. We are based in Maidstone and cover the whole town, Bearsted and the M20 villages, plus Chatham, Rochester, Gillingham, Strood and Rainham.

Why do roofs in Maidstone and Medway moss up so quickly?

Shade from mature trees around Maidstone and Bearsted, and damp estuary air in the Medway valley, keep roof slopes wet for longer. Moss thrives on slopes that do not dry out.

Can you reach a roof on a steep street in Chatham or Strood?

Usually. Access is assessed before we quote. If a platform cannot be positioned safely, we tell you and quote the alternative rather than improvising off a ladder.
