"My client, a window manufacturer, was alleged to have defectively designed and manufactured windows installed in hotels nationwide. Gene Summy and TLS Labs had the experience and knowledge necessary to help us defend the case. Gene was able to identify defects in the building envelope that allowed for water infiltration. He was critical of the testing methods used by another window testing company that didn't follow AAMA standards, and ultimately helped us posture the case for settlement."

What are people saying about us?
As District Sales Manager for Whitecap Construction Supply in Northern California I have been trying to solve leaky window problems for customers for years. Gene Summy of TLS Labs has been instrumental in helping me find solutions. His pre-folded corners are the only good answer I’ve found for recessed window applications. Gene’s expertise is invaluable as a resource for anything regarding window setting or remediation.
