Red Algae

Keep Your Home Beautiful: Red Gable Cleaning’s Softwash Can Remove Red Algae Stains

What is Red Algae and How Does it Affect Your Property?

Red Algae

Red algae can be a common problem for many property owners, particularly in areas with high humidity and rainfall. It is a type of green algae that gets its red color from large quantities of carotenoids, which are responsible for giving many foods their orange or red color. While red algae may not be harmful to your health, it can cause significant damage to your property’s exterior surfaces if left untreated.

Red algae thrives on damp, porous surfaces like rocks, trees, and houses, and if left unchecked, it will multiply rapidly. If the conditions are right, red algae can combine with fungus to form lichens, which are even harder to remove from surfaces.

While algae are capable of photosynthesis and produce the sugars that other biomass live on, red algae can create significant issues for building owners. The discoloration caused by red algae can make your property look unkempt and unprofessional, leading to a negative impact on your business or home’s value.

At Red Gable Cleaning, we have years of experience dealing with red algae and other forms of organic growth on properties. Our team of highly trained technicians uses the latest equipment and biocide chemicals to remove red algae from delicate surfaces like stone, brick, and render. Our Softwash system is safe to use on even the most delicate of surfaces, protecting the historic integrity of your building.

When we treat red algae, the cell walls are punctured, and the red carotenoids come flooding out. This is why a building will typically look worse for 24-48 hours after our treatment. However, all the staining caused by red algae will have disappeared within four to eight weeks, often much sooner.

We understand that preserving the aesthetic and historic value of your heritage building is critical, and our Softwash system is an effective way to clean and maintain your property’s exterior without damaging its unique features. Our technicians are experienced and knowledgeable in handling heritage building materials such as sandstone, limestone, and terracotta, and we use environmentally-friendly products that are safe for both the building and the environment.

Our Softwash system is safe, efficient, and effective, providing a stress-free solution for property owners to maintain the aesthetic and historic value of their heritage building.
