Jeff and Cody are excellent master electricians—great at tracking down the source of our legacy building's electrical issues, and then doing what was needed to fix the immediate problem AND hopefully forestall future problems!
We brought in SLTD Electric as part of a small remodel after purchasing a house. They were very responsive, clear in their communications, and helpful with a variety of projects. They were able to troubleshoot and test older wire and outlets, updating and replacing sockets and fixtures where needed. Also they installed a new sub-panel, and provided new wire runs for heat pumps and septic alarms. Quality workmanship and service.
I cannot recommend this company enough! On time, professional, diligent and extremely knowledgeable! Their work is bar none, don’t look anywhere else!
Excellent will use again
Super happy with the work SLTD did. They showed up on time, were really friendly, and got everything done quickly and properly. No mess, no hassle. Definitely someone I’d call again if I need more electrical work.
