testimonials
We ordered two custom-made Kalamein doors. These were produced with quality craftsmanship in a very timely manner. This company is truly an oasis in the desert! We will definitely be using Capitol in the near future as we only use top of the line products in our company.
I’ve already told the story to the local building supply company which had previously satisfied all my DIY needs for 31 years, and left them one of your business cards. I will send another to the other supplier that tried to help me with this project.
