Customer Testimonials

"Excellent job from start to finish. Our project manager, Dennis, did an excellent job addressing our concerns relative to noise and draft. We followed his advice and are completely satisfied with the results. The installation team consisted of 3 very capable and delightful young men who did a terrific job. The guys worked together very well, and they were polite and professional. The supervisor arrived to put the finishing touches on the job and the fellows cleaned up beautifully. I highly recommend SDI!"
