Keep the lights on and the doors open.

A business can’t work without power. Whether it’s a dead circuit in the break room, new lighting for a storefront or power for new equipment, we schedule the work around your hours so customers never notice.

Every license Thomas General Contractor holds is Dual — residential and commercial. With a KB-1 building license too, we can handle the electrical in a tenant improvement as part of the same job as the walls and the cooling.
