Home rewiring
Rewiring for older homes, including houses with knob-and-tube or aluminum wiring, by Martinez Electric LLC. We’re based in Derry, NH and take jobs in New Hampshire, Massachusetts and Maine.
What we rewire
Many older homes still have wiring that wasn’t made for today’s loads. Knob-and-tube wiring has no ground wire, and older aluminum branch wiring needs the right connections where it meets switches and outlets. Rewiring replaces it with new wiring that meets code.
- Knob-and-tube wiringReplaced with new, grounded wiring.
- Aluminum wiringOlder aluminum branch wiring, common in homes built in the 1960s and 70s.
- Whole-house rewiringNew wiring throughout, brought up to code.
- Grounded outletsThree-prong outlets that are really grounded.
Before you call
Tell us roughly how old the house is and what you’ve noticed: two-prong outlets, cloth-covered wire in the basement or attic, or lights that flicker.
