"I have worked with Gene Summy and TLS Labs for close to 20 years.
During this time period, Gene has provided expert counsel for both common and complicated window installation.  His expertise in forensic analysis of failed installations enables him to provide keen insight into best practices to prevent failure.
Gene has assisted with our window install details and provided jobsite training.  We’ve taken advantage of the TLS Labs testing facility to conduct tests of our Weather Resistive Barriers and Window Flashings.
Gene and his crew are true professionals.  They are highly respected in the window industry for their manufactured flashing products and their expertise in application of our flashing and sealant products."
