As a General Contractor it's always a little nerve wracking working with a new sub for the first time. John K was fantastic and did an excellent job representing GBM. Looking forward to working with them again.

GB Manchester is our "Go To" contractor for all of our data, fire and security needs. The tech's are always professional and go the extra mile. It is rare that I find any of their work that is not exceptional. If they do make a mistake they fix it FAST and with out charge. You can't go wrong if you employ this great company.

Glen Dimplex America GB Manchester did exceptional work in our warehouse and server room. The crew they sent each were very professional and completed the project ahead of the scheduled time. I will be looking to use them again for further projects.
