I have worked with Double D Fire at my apartment community. They were extremely professional and worked well with my team and residents. They were able to assist me with my annual fire inspection and back-flow. I was so impressed by their customer service that I now use them for all of our intrusion and fire alarm monitoring as well. They recently began selling their new product, Coverdome, which is a plastic dome that covers all fire sprinkler heads during the painting process during the make ready. This saves me a ton of money each month as I do not have any sprayed sprinkler heads that have to be replaced. We now only work with painters that use Coverdome in our apartments. I would recommend Double D FIre to any apartment community or commercial building in the Dallas / Ft. Worth area.
