One known area or circuit
Diagnose the active concern, correct the affected wiring or devices and verify the protection and grounding conditions within that scope.
Whole-home rewiring + renovations · Suffolk County
Plan the electrical system before the walls close.
Seafield organizes service capacity, room circuits, lighting, controls, devices and future loads as one clear scope—from layout through rough, trim and closeout.

Start with the project—not a long questionnaire
What is changing in the home?
Choose the closest path. Send the essential information now, then use the complete journey only when you want every decision explained.Targeted repair or complete rewire?
Access and repetition change the answer.
A failed device or one damaged circuit does not automatically justify rewiring the home. The complete path becomes stronger when wiring concerns repeat across rooms, grounding and protection are limited, circuits no longer match the home—or the walls are already open.Start with troubleshooting and safety →One opened area is changing
Coordinate new circuits, boxes, devices, lighting and controls for the renovated area while verifying how it connects to the system that remains.
Widespread condition or full access
Replace and redistribute branch circuits room by room, then coordinate the panel, service capacity, protection, lighting and future equipment as one design.
Before the first cable is installed
Furniture, equipment and daily routines belong in the plan.
What each room needs to do
Furniture, cabinetry, appliances, task locations, exterior use, lighting feel, switching, shades, EV charging, HVAC and backup-power plans shape the electrical layout.
What must be coordinated
Plans, framing, mechanical equipment, insulation, cabinetry, fixture support, inspection timing, finish responsibility and schedule must align before rough work closes.
The complete home systemThe Seafield rewiring standard
Six decisions in one electrical scope.
Service + panel capacity
Review existing equipment, calculated demand, breaker space and planned loads before deciding what remains or changes.
Room-by-room circuits
Separate kitchens, baths, laundry, bedrooms, living spaces, exterior areas and major equipment into a practical distribution plan.
Lighting + controls
Coordinate recessed and decorative fixtures, switching, dimming, scenes, exterior lighting and shade power before finishes.
Devices + daily use
Place receptacles, appliance connections, dedicated circuits and controls around cabinetry, furniture and how the rooms will function.
Protection + grounding
Apply the required AFCI, GFCI, surge, grounding, bonding, smoke and combination-alarm provisions to the defined project.
Testing + closeout
Complete trim, torque, labels, testing, punch-list work, owner orientation and documentation within the agreed scope.
Planning context—not a sight-unseen quote
Complete open-wall rewires are often planned around $14,000–$20,000.
The actual proposal follows the home, access and finish level. Service work, circuit count, kitchens and baths, lighting, controls, appliances, exterior power, permits and existing conditions can move the complete scope below or above that planning range.

Questions before the walkthrough
Plan the system while decisions are still inexpensive.
Browse rewiring and renovation answers →When does a home need complete rewiring instead of targeted repairs?
A complete rewire becomes more practical when outdated, damaged or ungrounded wiring is widespread; the room layout is changing; circuits are poorly distributed; or renovation walls and ceilings are already open. Seafield compares the affected systems and access before recommending a whole-home scope.
How much does a whole-home rewire cost in Suffolk County?
Many complete open-wall residential rewires are planned in the $14,000–$20,000 range, but square footage alone does not set the price. Service work, access, circuit count, kitchens and baths, lighting, controls, appliances, finish level, permits and existing conditions determine the written scope.
Should the service upgrade be included with the rewire?
Not automatically. Seafield reviews the service rating, equipment condition, calculated demand, panel space and future loads. A suitable existing service may remain; a deteriorated or undersized system may be more effectively coordinated with the renovation.
What should be decided before rough wiring begins?
Room use, furniture and cabinetry, appliance schedules, lighting and control zones, HVAC equipment, exterior power, EV or generator plans, device locations and future wiring should be reviewed before boxes and cables are placed.
Can Seafield coordinate directly with my builder or designer?
Yes. Plans, reflected-ceiling layouts, appliance and HVAC schedules, control decisions, inspection timing and finish responsibilities can be coordinated with the project team. The written proposal defines Seafield's scope and exclusions.
What happens after the rough inspection?
After required approvals and the other trades complete their work, Seafield returns for devices, fixtures, controls, panel completion, testing, labeling, punch-list work and final closeout within the agreed scope.
