About Us




With over a decade of experience in our own crawl space service company, we consistently found the need for custom doors due to sizing, shape of the door, or just wanting to provide a premium product to our customers. These were first built on site at customer homes, then in a garage, and once we moved into a warehouse that had the space for a door shop, we started crafting them for our own customers. This eventually became something we knew our friends in the industry needed too, and so Cathmer Crawlspace Doors was begun. 

We created a design that would stand the test of time and just as importantly, be easy to install.  We patented our design and now manufacture overlay and custom doors in Mount Pleasant, SC.
