Services

Cleaning is only a third of the job.

A pressure washer makes things look good for a month. Cleaning, protecting and maintaining makes them stay that way.

  • Moss-covered roof tiles on a cottage

    Roof cleaning

    Moss scraped and soft-washed off tiles and slates at low pressure — clean, without cracked tiles.

    Clean
  • Pressure washing a dark tarmac surface

    Driveways & patios

    Block paving, flags, tarmac and decking washed back to their original colour, joints re-sanded.

    Clean
  • Cladding half cleaned: algae on one side, the clean finish on the other

    Render & cladding

    Green and red algae staining lifted from render, cladding, fascias and soffits with a gentle soft-wash.

    Clean
  • Cleaning a window with a squeegee vacuum

    Window cleaning

    Frames, sills and glass cleaned with purified water, so they dry without streaks or spots.

    Clean
  • Clumps of moss growing between roof tiles

    Moss & weed removal

    Growth cleared from roofs, paths and paving joints, then treated so it’s slow to come back.

    Protect
  • Water beading on a protected surface

    Sealing & treatments

    A sealant or biocide finish that repels water, resists stains and stretches the time between cleans.

    Protect
  • Autumn leaves collected along a roof edge and gutter

    Gutter clearing

    Gutters and downpipes vacuumed out from the ground and checked for flow before they overflow.

    Maintain
  • Solar panels on a tiled house roof

    Solar panel cleaning

    Dirt and bird mess rinsed off with soft brushes and pure water, so panels aren’t working through grime.

    Maintain
