Have you noticed condensation on the inside of your building's windows during the early morning chill? Does a room seem impossible to keep warm, or cool, due to an incoming draft from outside? It may be time to have a look at your existing curtain wall and building sealants. If you can't remember the last time that they were replaced, then it's possible that the sealants have reached their life expectancy.
Most waterproofing/weatherproofing sealants are designed to last about 10-15 years. If your sealant appears to be shrinking or pulling away from the surface, has any deterioration signs, or is discolored or brittle, these are signs that it's time to apply new sealant to your building's exterior. Delaying this process can cause premature deterioration of the wall structure, damage your building's finish, advocate mold and mildew growth, and affect the interior air quality. In the long run, the preventive cost is less than the consequential costs of deferring on this project.
Duggan and Associates has a skilled team on-hand to weatherproof your building. Most recently we performed a full sealant application on the CBRE managed Pacific Corporate Towers in El Segundo, and the Hines managed 10100 Santa Monica Blvd. in Los Angeles/Century City using the Dow Corning 791 sealant product in a black finish, which recently received Product Certification from the Singapore Green Building Council. This product is ideal for expansion, connection, perimeter, and other flexible joints. If your building is due for a new sealant application, be sure to give Duggan and Associates a call, because yes - we do that too.
