Moss, Mould and Lichen Removal

If you have a moss, mould or lichen problem you are at the right place! 

Talk to the Stratacote team for advice on the complete removal of all moss, mould and lichen from your building surfaces, be it a roof, wall, footpath or driveway.

4 key reasons to remove moss, mould and lichen growth:

  • Slippery & Hazardous: Lichen and mould growth makes footpaths and driveways slippery and dangerous for pedestrians and vehicles. You should ensure these areas are free of such growth to prevent injury and accidents.
  • Surface Damage: Moss mould and lichen growth can also cause damage to roof and wall surfaces. You should remove such growth to prevent deterioration of your surfaces.
  • Health Hazard: Mould is a health hazard, particularly to anyone with respiratory problems. Whilst external mould growth may not cause health issues, it can be an indication or precursor to internal mould growth which comes with serious health concerns.
  • Unsightly: The unsightliness of moss, mould and lichen growth on any surface reduces street appeal and appearance, so if you are thinking of preparing your property for sale, removing such growth is advisable to increase street appeal. You should also be maintaining your surfaces to get the maximum life from them.

The Stratacote difference:

The Stratacote team recommend our highly active surface solution which kills the growth and when used on masonry surfaces it penetrates into the material to kill any tendrils and spore that have penetrated into the brick or mortar that could cause re-growth, it also has high residual properties which prevent re-growth and ensures your surface is free of any moss, mould or lichen for approximately 3 years!

Depending on your individual requirement, a Water Repellant treatment is recommended to be applied on porous surfaces to waterproof your surface and slow down the weathering process. By waterproofing porous bricks, it serves to create a drier and more thermally efficient home.
