Customer Testimonial:

“I must admit I was skeptical about pre cut rafters but after the pre-engineered flooring system came together so nicely you earned my confidence.

Our reputation depends on building custom homes to exact standards. The coordination between the field and your shop was flawless and the final product was installed quickly without issues.

Well done... I will be working both systems into our future projects.”

- David Brookes, President, Brookes and Hill Custom Builders
