Why consider a Building Envelope Consultant?
On the front end, prior to construction, we can provide design assistance to help you prevent leaks or other defects after the building is built. On the back end, if you have existing trouble with water infiltration, air infiltration, or other defects in the building envelope, we can assist you with finding the cause and providing the repair procedure. An overwhelming number of lawsuits are due to failures in the building envelope. We can help you to avoid costly failures and prevent costly lawsuits by getting the components of the vertical facade built and installed correctly.
The exterior cladding of a building is it's main aesthetic component
Our desire is to help architects and owners see their aesthetic goals come to fruition without compromising any building performance, and to help them avoid or repair the very common, frustrating and costly problems of water infiltration and condensation. In addition, to provide a building that will see increased longevity and maximum efficiency for our clients is a very rewarding aspect of our business.
Water infiltration and condensation in exterior cladding such as windows, doors, skylights, curtain walls, etc. are continually noted as the number one area of lawsuits for owners and architects. It would greatly benefit an owner to have an experienced, expert building envelope consultant at their disposal.
