    One Crew for Every Wire in Your Home

    Whether you are framing a new build on Daniel Island, renovating a downtown Charleston kitchen, or replacing seventy-year-old cloth wiring in a West Ashley ranch, the fundamentals are the same: every circuit must be sized correctly, terminated cleanly, protected at the panel, and inspected before it goes live. Our crews handle the entire spectrum of residential wiring with the same code discipline from rough-in through cover-up.

    For new construction, we walk the framing with your builder, lay out device boxes for real-world furniture placement, and rough in every circuit, low-voltage run, and dedicated load before drywall. For remodels, we extend and upgrade existing circuits without overloading them, fish wire through stud bays to avoid unnecessary drywall demo, and add dedicated lines for new appliances and lighting.

    For full rewires, we work room by room in a live-in friendly sequence, restore power at the end of every day, and document the work with photos and circuit maps your insurance carrier can use. Most rewires include a panel upgrade to 200A service, whole-home surge protection, and GFCI/AFCI coverage on every required circuit.

    We wire homes across Charleston, Mount Pleasant, Daniel Island, James Island, Johns Island, North Charleston, West Ashley, Summerville, Goose Creek, Hanahan, Moncks Corner, Isle of Palms, and Sullivan's Island. Every job is permitted, inspected, and backed by a written workmanship warranty.

    Wiring and rewiring is the foundation of every safe, modern Charleston home. EmergenServe's licensed electricians design, install, and replace residential wiring across Charleston, Mount Pleasant, Daniel Island, James Island, Johns Island, North Charleston, West Ashley, Summerville, Goose Creek, Hanahan, Moncks Corner, Isle of Palms, and Sullivan's Island. From a single new circuit in an addition to a full knob-and-tube replacement in a historic downtown home, every job is permitted, inspected, and warrantied.

    New Construction Wiring, Done by Electricians Who Show Up On Schedule

    On a new build, the electrical scope starts long before the rough-in walk. We meet your builder at framing, mark device locations against the cabinet and furniture plan, confirm HVAC and appliance loads with the GC, and pull a service entrance that matches the future capacity of the home, not just the day-one demand. Every circuit is sized to NEC ampacity, every kitchen and laundry gets dedicated 20A small appliance circuits, and every bedroom and living area gets AFCI protection at the panel.

    We coordinate rough-in inspection, insulation timing, and trim-out so the build keeps moving. Final walkthrough includes a circuit map, breaker directory, photo record of every box, and the certificate of occupancy electrical sign-off in your handover packet.

    Remodel and Addition Wiring Without the Drywall Carnage

    Most remodels do not need every wall opened to add the wiring a modern kitchen, bath, or primary suite demands. Our electricians fish wire through stud bays, use old-work boxes, and stage access cuts where the drywall is already coming down. We calculate the existing circuit load before tying in new outlets so nothing pushes past 80% capacity, and we add dedicated circuits where modern loads (induction ranges, microwaves, dishwashers, on-demand water heaters, mini-splits) require them.

    On Charleston historic homes, we navigate plaster walls, balloon framing, and original fire blocks without compromising structure. On Mount Pleasant and Daniel Island new builds undergoing first-renovation, we work directly with the original panel and rework circuits to match the new floor plan.

    • Dedicated kitchen and bath circuits sized to NEC
    • Strategic drywall access with patching coordinated
    • Recessed lighting, under-cabinet, and pendant circuits
    • Bath fan, heat lamp, and dedicated steam shower wiring
    • Primary suite TV, sconce, and switched-outlet runs
    • Permit and inspection handled by our office, not yours

    Complete Rewiring for Older Charleston Homes

    Knob-and-tube, paper-jacket cable, and 1960s-70s aluminum branch wiring are all known fire and insurance risks. Many older downtown Charleston, North Charleston, and West Ashley homes still have one or more of these systems hiding behind plaster and paneling. A full rewire replaces every branch circuit with modern copper Romex, brings the service entrance up to 200A, adds GFCI and AFCI protection on every required circuit, and gives your insurance carrier the documentation they need to keep coverage in place.

    We work room by room in a live-in friendly sequence, restore power at the end of every day, and stage drywall openings to minimize disruption. Most full rewires of a 2,000 to 3,000 square foot Charleston home are complete in 3 to 7 working days.

    Why Lowcountry Wiring Is Different

    Coastal humidity, salt air, hurricane surge events, and historic construction methods all change how residential wiring should be specified. We default to corrosion-rated boxes and stainless hardware on every outdoor and garage device, install Type 2 surge protection at the panel on every new service we touch, and rough in generator and EV charger circuits during builds and rewires so they do not become a future demolition project.

    For waterfront homes on Isle of Palms, Sullivan's Island, Folly, and Kiawah, we go further: marine-grade fittings, sealed in-use covers on every exterior receptacle, and bonded raceways at every dock, boat lift, and pool circuit per NEC Article 680.

    Frequently Asked Questions

    How long does new construction wiring take?

    A typical 2,500 to 3,500 square foot Charleston new build takes 5 to 10 days for rough-in and another 3 to 5 days for trim-out, spread across the construction schedule. We coordinate with framing, insulation, and drywall so the build keeps moving.

    Will my homeowners insurance require a rewire?

    Many Lowcountry insurance carriers now require knob-and-tube and ungrounded aluminum branch wiring to be remediated or replaced as a condition of coverage. We provide written documentation of the work and the upgraded panel for your carrier on every rewire.

    Can you wire generator and EV charger circuits during a build?

    Yes, and we strongly recommend it. Roughing in a 240V EV circuit and a generator inlet during construction costs a fraction of retrofitting later. We plan capacity, conduit, and panel space on every new build and rewire.

    Equipment & planning guide · the Charleston Lowcountry

    Planning circuits, rewiring, and electrical alterations

    Use this guide to compare options before booking. For this work, the important starting points are the condition of existing conductors, the planned loads, and access through finished walls and ceilings. Exact equipment selection follows an assessment of your property, the manufacturer’s instructions, and applicable local requirements.

    01

    A new circuit is different from extending an old one

    Extending a circuit can be appropriate when its capacity, grounding, conductor condition, and protection suit the new use. A dedicated circuit creates a separate supply for equipment or a defined area and may be the better choice for larger loads. The electrician checks the existing installation before deciding whether either approach is suitable. Adding devices to a damaged or overloaded circuit only spreads the underlying problem.

    Circuit design includes conductor type and size, routing, physical protection, box capacity, and the equipment’s connection requirements. Long runs or demanding loads may call for additional design attention. The pictured Leviton load center shows the distribution equipment where branch circuits originate; it does not establish that a panel replacement is needed for every wiring job. Ask which parts of the existing system can safely remain and why new work is being separated from older wiring.

    Whole-home rewiring versus targeted repairs

    A whole-home rewire is a coordinated project, not a collection of faceplate replacements. It can address deteriorated insulation, missing grounding conductors, insufficient circuits, or extensive alterations that are difficult to verify. Targeted repairs may be appropriate when a clearly defined part of an otherwise sound installation is defective. The distinction requires inspection and testing, not a judgment based solely on the year a house was built.

    Older two-wire circuits require careful handling when devices are replaced. GFCI protection can be an allowed part of certain replacement arrangements, with the required identification, but it does not add an equipment grounding conductor. Discuss whether the objective is a limited correction, increased capacity, or a complete modernization. Those goals lead to different scopes, costs, access needs, and documentation. The pictured receptacle is a device example, not evidence that concealed wiring has been upgraded.

    Lowcountry conditions that affect the work

    Humidity, outdoor moisture, retained finishes, and concealed wiring can all affect the scope of an electrical project in the Lowcountry. Coastal exposure calls for equipment suited to the actual mounting location, not a generic claim that every enclosure is weatherproof. In older buildings, assess the conductors and prior alterations rather than judging by faceplates. Newer construction still needs a load calculation when substantial equipment is added.

    For this project, assess the condition of existing conductors, the planned loads, and access through finished walls and ceilings at the actual address. Confirm the parcel’s jurisdiction before scheduling work that requires a permit. Inspection or utility scheduling can affect completion; ask about the sequence rather than treating an estimated date as a guaranteed reconnection time.

    Prepare for a useful estimate

    • List renovation areas and the equipment planned for each room.
    • Share known inspection findings or prior wiring alterations.
    • Discuss finish repairs and access before work begins.

    Pricing depends on the agreed equipment, routing, access, existing conditions, and any required permits or utility work. Existing starting prices elsewhere on this page are not a quote for every configuration. Compare written scopes and confirm finish repairs, supplied materials, testing, and exclusions. No new price or manufacturer warranty is implied by the product examples in this guide.
