What Our Clients Say

Vulcan Construction Inc.

Lewis Bass provided excellent third party electrical evaluation services for unlisted equipment found in a recent project of mine. The team at LB followed up with a detailed scope of work to correct and expedite the inspection process and were very effective in communicating where my client was in the process in addition to fulfilling their planned date of completion. They are most definitely my go to partner if I need a third party review in the future.

Chris Wyand

Creative Building Solutions, Inc.

I have used them several times on industrial projects to evaluate unlisted tools as part of the scope of adding an additional production line at a food packaging plant in Morgan Hill.Guided by an owner who is not only highly qualified she is such a neat person that you can’t help but want to send them business. Scheduling is smooth and they have always been available for rush work. Their employees are professional and their thorough reports breeze right through with the building officials. Should you ever need this specialized service I highly recommend this company.
