    I needed to upgrade my electrical panel and began a search for electrical contractors online, and came across 24/7 Electrical Service Inc where I spoke to Moe. From the very beginning Moe was friendly and very informative. The work couldn't be done right away because we were waiting to be scheduled by the power company for power shut down. But through the whole process Moe handled all applications and communications with the power company, all while keeping me informed as to where the process currently was. In the end Moe and another electrician came through and completed the work. It was well done, with the wires neatly placed and at a reasonable price. I would highly recommend their service.

    We were very happy with the service received from T.H. Oliver with our 16 year old water heater. Darren and Terry replaced the water heater in a morning. Very professional, office staff were great, answered any questions and Terry came back on Sunday to make sure the heater was working. Have used T.H. Oliver in the past for our furnace.

    This job required a full demolition and installation of a walk in bathtub, a new window, wall and ceiling tile, repairs and refreshment to the remaining drywall area and installation of a pocket door. The job required the involvement of several tradesmen. All of the guys were great. They obviously knew what they were doing, worked quickly with minimal intrusion on us. they were friendly and willing to answer any questions or concerns. they made a minimum of dirt and dust and cleaned up very well every day. the job was completed on time and on budget and we love it.
