Masonry contractors near me Chicago
Historic masonry has a visual character created by original materials, craftsmanship, and decades of natural aging. When repairs become necessary, preserving that character requires more than filling deteriorated joints with new mortar. Proper matching is one of the most important parts of historic tuckpointing.
Older buildings often contain mortar that differs substantially from modern products. Traditional mixtures may contain higher amounts of lime and locally sourced sand, creating distinctive colors and textures. Using a generic modern mortar can result in joints that look dramatically different from the original masonry.
Experienced masonry contractors near me Chicago examine existing mortar before beginning restoration. The objective is to understand not only its visible color but also its composition and physical characteristics. A replacement mixture should work with the historic brick rather than simply resemble it.
This is important because many older bricks are softer than contemporary masonry units. Installing excessively hard mortar can change how moisture and movement are handled by the wall. Instead of the mortar absorbing normal stresses, the brick may become damaged.
Color matching presents its own challenges. Decades of exposure can change the appearance of original mortar. Different sections of the same building may even have slightly different shades depending on sunlight, rain, previous repairs, and pollution.
For this reason, masonry contractors may prepare multiple test samples for historic tuckpointing. Once the samples cure, they can be compared with the original joints under normal lighting conditions. Texture and joint profile should also be evaluated.
Poorly matched repairs can permanently alter the appearance of an otherwise well-preserved facade. Rows of bright or contrasting mortar joints immediately reveal where work was performed.
Proper tuckpointing takes a more careful approach. By matching color, texture, composition, and joint style, qualified masonry contractors can repair deteriorated areas while maintaining the architectural character that makes historic brick buildings distinctive.
