We had used TBS for a new construction apartment complex in Sacramento CA. and we are extremely satisfied with the product, from the great finish, and the pre-punched nailing fin, to dealing with Justin. it was a great experience and we will definitely be working with TBS again.

Worked with Justin Grebasch at Thermally Broken Windows. The process was during COVD and the service was exceptional. He gave me a lead time and was able to bet it by one week. Will work with them again.
