So many exterior building materials are actually quite porous. This means that they can often hold moisture and remain quite damp for long periods. This encourages algae and lichen to develop on the surface, making it look quite dirty and unsightly. If left untreated, moss can also begin to develop which can lead to degradation of the surface, which can cause other more serious structural issues over time.
Softwashing uses a chemical approach to treat these areas in order to kill off the organic growth. Some of these chemicals can also have a preventative quality, and regular applications can be a great way to maintain a property in the best condition, even extending the life of the surface.
A regular treatment of a softwash can kill off the algae spores that can begin to develop on these exterior surfaces. It’s this black algae that can make an area look grubby and unsightly. A specialist treatment every 2/3 years can keep these areas looking fresh and bright.
If neglected for several years, lichen and moss can develop on porous building surfaces. This can often lead to further damage being caused to various parts of the structure. Regular maintenance is a much better solution, and can even extend the life of many exterior surfaces.
