Replacing control joint caulking on commercial structures is just one of the many maintenance procedures required in order to preserve the exterior envelope of the building.  

Control joints are degraded by weathering and will last 5 to 30 years depending on the type of sealant used, the movement the joint is subjected to, the amount of exposure which the joint receives, and also the type of building material. We typically recommend replacing expired control joints with silicone caulking due to its extended life expectancy when compared to urethane caulking. We believe that this extended life expectancy, and a variety of other factors, make silicone a far superior product for the exterior facade of commercial properties. 

We recommend completely removing expired control joints, and the installation of a new backer rod, instead of skim coating over expired control joints. This helps to create the correct width to length ratio for the newly installed caulking and maximize the amount of elongation for the joints. A better range of elongation typically results in longer-lasting caulking joints, which ultimately results in increased lifespan for the sealant, and decreased caulking costs for the property owner. Call us today so that we can discuss your expectations for a control joint caulking business, and we can show you the ways in which we are ready to exceed your expectations.
