We assess your electrical system, identify upgrade needs, design the circuit layout, and specify all materials and fixtures.
All DOB electrical permits are filed, and work is coordinated with your renovation schedule and other trades.
New circuits, outlets, switches, and fixture boxes are installed, with wiring routed before walls are closed.
Devices, fixtures, and panels are connected, labeled, and tested. City inspection is scheduled and completed.
If your Nassau County home has a 60-amp or 100-amp panel, a panel upgrade to 200 amps is typically recommended - especially if you're renovating, adding appliances, or installing central AC or an EV charger. Older single-family estates, colonials, split-levels, Cape Cods, and waterfront properties often have undersized panels that can't safely support modern electrical loads.
A 200-amp panel upgrade in Nassau County typically costs $3,000–$6,000 including permits and inspection. Full apartment or home rewiring ranges from $8,000–$25,000+ depending on size and complexity. We provide detailed estimates after assessing your existing electrical system.
Yes. All electrical work in Nassau County requires DOB permits and must be performed by NYC-licensed electricians. Nassau County projects require town or village building permits rather than NYC DOB. Each municipality has its own process - we handle permitting in Garden City, Great Neck, Manhasset, and all Nassau County jurisdictions. Lion Construction Management handles all permitting, inspections, and code compliance on your behalf.
Absolutely. We integrate smart lighting, motorized shades, whole-home audio, video distribution, smart locks, and voice-controlled systems during renovation when it's easiest and most cost-effective to run wiring. Retrofit installations are also available.
