As an indication of our pride in offering the latest state of the art in electrical innovation, McWilliams is a BICSI Registered Communications Distribution Designer , a certified Telecom Infrastructure Design and Build firm, as well as a certified Telecom, Fiber / Copper Cable E.I.A. / T.I.A. testing and certification company. This includes fiber‐optics, broadband technology, “smart building” applications, and tele‐data work. We can provide everything from supplying complete systems to wiring service, including all tele / data changes, additions, or reductions. We are effectively providing the same service that was performed by AT&T before divestiture. However we can accomplish it at a great savings to you and with more overall efficiency.

Another staple feature keeping McWilliams ahead of the curve is our in‐house Engineering Division.

McWilliams is a fully insured design/build contractor that can design your project and execute the job all the way through to electronic As‐Built drawings when the job is completed.

McWilliams is proud to be serving its customers since 1922 with customer service and satisfaction before, during and after the job is completed. McWilliams would be glad to submit to you the current union wage rates particular to your company needs.
