The use of sealants to seal moving joints or the exterior building components (such as windows expansion joints, control joints and the like) is a common maintenance problem. Most sealants are designed with a 5-10 year life span, so this is an on-going factor in keeping water infiltration into the building envelope to a minimum. We use a wide variety of sealants by Tremco, Vulkem and Dow-Corning - which are the leading manufacturers in the sealant industry. Full specifications for glazing and or re-caulking are a part of every quotation and project.
