Sealants protect your building from the elements such as extreme weather, water damage, and pests, which can drastically impact your building's structure.​ Buildings also undergo constant movement, which is normal, but sealants age over time due to ultraviolet degradation and pollution. Movement can increase the failure rate.​​ To maintain a solid defense, CAWC will repair sealants or apply the proper sealant specifically designed for your commercial application.
