Brownstone Gut Renovations
When a brownstone is stripped to the studs, we rewire the whole house while the walls are open — new copper, grounded outlets and AFCI/GFCI throughout — so the wiring never holds up the rest of your reno.

Wiring & Rewiring in Brooklyn
Behind the plaster of Brooklyn's brownstones and row houses runs some of the oldest wiring in the city — knob-and-tube and cloth-insulated cable that fails inspection, scares off insurers and quietly raises the risk of an electrical fire. Precision Power rewires Brooklyn homes safely, and times whole-home rewires to the moment the walls are already open.

Why Brooklyn's Old Houses Need Rewiring
Brooklyn's housing is gorgeous and old. The brownstones of Park Slope and Brooklyn Heights, the limestone and brick row houses of Bed-Stuy, Crown Heights and Sunset Park, and the wood-frame homes of Greenpoint and Flatbush were mostly wired generations ago — long before central air, induction ranges or a dozen devices on every floor. Open the walls and you'll often find knob-and-tube or brittle cloth-insulated cable that no modern inspector will sign off on.
That's exactly why the smart move in Brooklyn is to rewire during the gut renovation. When a brownstone is taken down to the joists for a kitchen-and-bath overhaul or a parlor-floor reconfiguration, the walls and ceilings are already open — the single most expensive and disruptive part of any rewire is already done. We pull new copper, add grounded outlets and AFCI/GFCI protection while the access is there, so you never have to break finished walls twice.
And it isn't only the big brownstones. The one- and two-family homes in Bay Ridge and Marine Park usually don't need a full rewire — they need new dedicated circuits for an added bathroom, a basement apartment or a kitchen full of modern appliances. We file with the DOB, coordinate the Con Edison side, and leave you with wiring that passes inspection and satisfies your insurer.

What's Different Here
Rewiring That's Specific to Brooklyn
A rewire in a Park Slope brownstone is a different job than one in a Bay Ridge two-family. Here's where our local experience shows up.
Knob-and-Tube Removal
Old Brooklyn row houses are full of ungrounded knob-and-tube and cloth-insulated cable. We safely retire it, run modern grounded circuits, and clear the way for your insurance certificate.
New Circuits for 1-2 Family Homes
In Bay Ridge and Marine Park, most homes just need new dedicated circuits — for a basement unit, an added bath or a modern kitchen. We add them to code without rewiring the whole house.

"We were mid-gut-reno on our Park Slope brownstone when the walls came down and exposed knob-and-tube everywhere. Precision Power rewired the whole house while it was open, added grounded outlets and GFCI, and got us through inspection. Couldn't have timed it better."

Brooklyn Wiring Questions
Wiring & Rewiring in Brooklyn — FAQs
Should I rewire my brownstone during the gut renovation?
Almost always, yes. The most expensive part of any rewire is opening walls and ceilings — and during a gut renovation that's already done. Rewiring while a Brooklyn brownstone is stripped to the joists means new copper, grounded outlets and AFCI/GFCI go in without breaking finished walls twice.
My Bed-Stuy row house has knob-and-tube wiring — is that a fire risk?
Knob-and-tube is ungrounded, its insulation is brittle with age, and it's a leading reason older homes fail inspection — many insurers won't even write a policy on it. We safely remove it and run modern grounded circuits so your Bed-Stuy home is both safe and insurable.
I just need a few new circuits for my Bay Ridge two-family — not a full rewire.
That's common in the one- and two-family blocks of Bay Ridge and Marine Park. We add dedicated circuits for a basement unit, an extra bathroom or a modern kitchen without rewiring the whole house — all run to code and filed with the DOB.
Do you handle the permits and Con Edison for a Brooklyn rewire?
Yes. We file the electrical permit with the NYC DOB, coordinate any Con Edison disconnect/reconnect, and manage the inspection from start to finish — handing you the Certificate of Electrical Inspection your insurer and the city want to see.
