Verdict

The right pick depends on how much of the job is purely electrical versus multi-trade. If the generator install is a standalone electrical project, panel work, transfer switch, dedicated circuits, Mr Electric's specialist focus and its track record on similar rewiring and panel jobs make it the tighter fit, especially with pricing held to estimate and follow-up visits included. If the project also touches gas lines, HVAC, or other systems that need one company to coordinate, Davis Services' multi-trade setup and larger volume of proven jobs offer more built-in coverage, at a premium price.
