What People Say

"We use Glenco Inc. at PennKraft Building Systems because of their reliability and detailed work. They have always went over and above what we had asked them to do and have always tried to accommodate our unusual requests. In my opinion Glenco Inc. is the premier Engineering firm for the modular housing industry."

− Rick Devey, Engineering Manager PennKraft Building Systems, LLC.

"The team at Glenco has not only helped us exceed our goals but, has done so with value and completion deadlines as priorities. Once construction has started, the project support is not over for Glenco. Time is money when site issues arise and when an unforeseen problem occurs, Glenco has stood beside us while we work together to find quick and creative solutions. We have become accustomed to excellent communication and quick responses.

− Bernie Hackenberg, Engineering Director, Durabuilt Homes, LLC
