At Diamond Sea Glaze our quality is unmatched, creating industry benchmarks in the marine closure market. We take great pride in our work and it shows with how our customers respond. Here’s just a few examples of what Diamond Sea Glaze customers have to say about our products:

“Thank you for the outstanding customer service support you provided to me as a Diamond Sea Glaze customer. From my view, you did an outstanding job and turned me into a Diamond Sea Glaze customer for life! With regard to my boat, the priority has always been; Quality, Schedule and Cost. I appreciate your support ensuring that my new windows are of the highest quality which Diamond Sea Glaze stands for.

For me, there are many manufactures of marine windows, and I have spoken to them all. But for me, the differentiator is the one that stands behind their product. Diamond Sea Glaze is the leader in my book and this will be shared with every yard, builder and friend I talk to”.

WOW! The window turned out exactly as we had envisioned. We were able to mount the frame in the dodger without a problem and we continue to have neighbors on the dock tell us how great the window looks. Best wishes for continued success. We will be quick to recommend DSG in the future.

The overall quality of Diamond Sea Glaze is just so much better. The finish, accuracy of sizing, the way products are crated, everything is done so nicely. It is a real pleasure working with the Diamond Sea Glaze sales representative. It felt like this company knows its business and understands customer requirements. There’s a reason I am doing business with Diamond Sea Glaze. I get a better quality product over other companies and they do it right. They deliver!
