The Unseen Damage Caused by Moss and Lichen: Why Professional Exterior Cleaning Matters


Homeowners invest a great deal of time and money in maintaining the appearance and structural integrity of their homes. One area that is often overlooked, however, is the damage caused by the growth of moss and lichen on exterior surfaces. These seemingly innocuous organisms can cause significant and costly damage if left unchecked. In this blog post, we will delve into the destructive nature of moss and lichen and discuss why professional removal is essential to prevent further damage to your home’s exterior.

The Impact of Moss and Lichen on Your Home’s Exterior

Moss and lichen are natural organisms that can thrive in various environments, including the exterior surfaces of your home. While they may add a touch of rustic charm, they can also cause significant damage to your property, particularly on color-through or painted render surfaces.

  1. Moisture retention and penetration: Moss and lichen retain moisture, which can seep into the render or paint layers, causing cracks and deterioration. In colder climates, the freeze-thaw cycle can exacerbate this problem, leading to further damage and costly repairs.
  2. Surface degradation: The growth of moss and lichen can break down the integrity of the render or paint, causing it to flake or crumble. This degradation not only detracts from your home’s appearance but also exposes the underlying materials to the elements, leading to further damage and decay.
  3. Structural damage: If left unchecked, moss and lichen can grow into crevices and gaps in your home’s exterior, compromising its structural integrity. Over time, the organisms can cause damage to the underlying brick or stonework, which may necessitate costly repairs or even replacement.
  4. Negative impact on property value: A well-maintained and visually appealing home is more likely to retain or increase its value. Moss and lichen growth can make your property appear poorly maintained, which can negatively affect its resale value.

The Importance of Professional Removal

While it may be tempting to tackle moss and lichen removal yourself, there are several compelling reasons to enlist the help of a professional exterior cleaning company:

  1. Safety: Moss and lichen removal can be a hazardous task, particularly when dealing with hard-to-reach areas, such as roof tiles or high walls. Professional cleaning companies have the equipment and expertise to ensure safe and effective removal, minimizing the risk of injury or property damage.
  2. Expertise: Professional cleaners are experienced in identifying the most appropriate cleaning methods and products for your home’s specific needs. Some cleaning techniques, such as pressure washing, can cause further damage to render or paint if not used correctly. A professional cleaning company will select the most effective and least invasive method to preserve the integrity of your home’s exterior.
  3. Long-term prevention: In addition to removing existing moss and lichen, professional cleaning companies can also provide treatments to prevent future growth. These treatments can save you time and money in the long run by reducing the need for frequent cleanings.
  4. Comprehensive service: Professional cleaning companies often provide a range of exterior cleaning services, including gutter cleaning, window cleaning, and driveway or patio cleaning. By enlisting a single company for all your exterior cleaning needs, you can streamline the process and ensure a consistent level of care for your property.


Moss and lichen growth on your home’s exterior may seem like a minor issue, but it can lead to significant and costly damage if left untreated. By enlisting the help of a professional exterior cleaning company, you can protect the integrity and value of your home, while also preserving its appearance for years to come.
