Houses change hands, and a 1949 house brings paperwork with it. A buyer's inspector lists the two-prong outlets, the open junction box in the basement, the fuse panel and the knob-and-tube remnants behind it. Sellers want the list cleared; buyers want to know what it costs. We do both, with a written price per item.
Grounding is the biggest line on most of those lists. Where a ground path exists, we install grounded outlets. Where it does not, GFCI protection meets code and makes the outlet safe for modern plugs. A fuse box becomes a breaker panel, and knob-and-tube remnants come out for good.
Our electricians are Thomas Edison Electric employees, not subcontractors. They leave from home, around Delaware County, in fully stocked TEE vans. Late on our part means the dispatch fee comes off.
