Boston Masonry Restoration: Repair Damage from Direct Sunlight


Boston Masonry Restoration: Repair Damage from Direct Sunlight

When we talk about damage to masonry and brick buildings, we usually focus on age, weathering, and water damage. However, damage can come from another, perhaps unexpected, source: the sun. That’s right, even good weather can damage masonry over time. When our team at Abbot Building Restoration assesses a masonry restoration project in Boston, we typically see four types of damage to masonry from sunlight: UV radiation damage, damage from thermal cycling, moisture damage, and algae or moss growth.


Here’s how we repair various types of damage from sunlight in a Boston masonry restoration project.


UV Radiation Damage

Over time, UV radiation from the sun can deteriorate bricks, mortar, and other elements of the masonry. We take these steps to repair the damage:


Thermal Cycling Damage

As the sun heats and reheats the masonry, the materials expand and contract, causing microcracks and reducing the strength of the stone.


Moisture Damage

Direct sunlight heats any water trapped in the masonry. The heat expels it from the materials, and then the water condenses on the surface, leading to further water damage.

Heating, expelling, and condensing water


Algae and Moss Growth

Warm materials retain moisture, creating an environment for algae to grow. The continued sunlight also creates the conditions for photosynthesis, encouraging further growth.
