Since the inception Tatley-Grund's primary focus has been to continually improve the quality of our services. One method used to reach this goal is to research and educate our staff on new technology affecting construction materials and methods. This focus lead us to the necessity of designing and constructing our own custom testing laboratory in 2002. The services we provide include pressure differential testing for structural, air and water infiltration on:

• Wall Systems
• Window Units / Window Installations
• Building Envelop Interface Details
• Cladding Systems
• Weather Resistive Barriers
• Doors / Sliding Glass Doors
• Air Flow Through a Variety of Building Materials

In addition to confidence testing on our existing projects for quality control purposes, our customers have utilized these services to solve specific building problems. For example, recently we designed a custom permanent repair to existing windows on a 14 story apartment building, saving the owner approximately $450,000 over their only other option of total replacement.

If you're a building owner, construction consultant or manufacturer looking for the confidence that your cladding, windows, materials or design details will perform under real life conditions TG can meet your needs. Contact us at 206-523-4653 or via e-mail.
