Whole-house rewiring in Park Slope, Brooklyn is the daily work of Brooklyn House Rewiring, and this brownstone neighborhood keeps our crews busy. We fish modern grounded copper cable through century-old plaster walls with minimal damage, then replace the brittle knob-and-tube that insurers no longer accept. Undersized 60- and 100-amp services on these row houses get upgraded to 200-amp breaker panels sized for today's loads. Park Slope homeowners call us when the wiring behind a landmarked facade has to be brought up to code without tearing the house apart.
Park Slope is one of Brooklyn's most sought-after neighborhoods, defined by rows of brownstone and limestone town houses bordering Prospect Park, much of it inside a landmarked historic district. These pre-war homes were commonly wired with ungrounded knob-and-tube and fitted with 60- or 100-amp services never meant for central air, EV charging, or a modern kitchen. That combination of aging wiring and undersized panels behind protected plaster makes careful whole-house rewiring far more valuable here than a quick patch.
The pre-war brownstones of Park Slope were wired with knob-and-tube that is now brittle, ungrounded, and refused by most insurers. We map every run, fish grounded copper NM cable through the existing wall cavities, and remove the old conductors so nothing live is left buried. Working carefully through plaster keeps damage to a minimum on a landmarked home while the finished wiring is fully grounded and up to code.
Many of these row houses still run on a 60- or 100-amp service that trips under the demands of a modern household. We upgrade the service entrance and install a 200-amp breaker panel with room for dedicated circuits, then add GFCI and AFCI protection where code requires it. Every upgrade is permitted and scheduled for inspection so the new service is signed off correctly.
Rewiring a protected brownstone means protecting the plaster, trim, and original detail as much as the wiring itself. We open the fewest access points possible, snake cable through walls and floor cavities, and patch what we do open. A licensed master electrician oversees the work so the finished job satisfies both the historic district and the electrical code.
