Why it does not pay to wait
Wiring cut rate during construction is buried behind drywall for the life of the home. Undersized service, missing circuits, and sloppy rough-in get expensive to fix once the walls close. The one clean shot to do it right is while it is still open.
New construction is your one clean shot to wire a home right, before the drywall closes it up. We plan the circuits around how you actually live, rough it in clean, and trim it out so every switch, can, and outlet lands where it should.
Custom homes, additions, garages, and ADUs. We work off the plans, coordinate with your builder, and keep the electrical on the critical path instead of holding it up.
New construction wiring we handle
- Full rough-in for custom homes and additions
- Service, panel, and distribution sizing
- Recessed and layered lighting design
- Dedicated circuits for kitchens, shops, and EV
- Low-voltage, data, and structured wiring rough-in
- Trim-out, device install, and final inspection
What you can check yourself first
Before you call, here is what you can safely check on your own. Even if you still call us, you will walk in knowing more than you did.
- Walk the plan and mark where you actually live: where the TV, the desk, the shop tools, the EV go.
- Decide the big loads early: EV, heat pump, pool, shop, so the service is sized once.
- Note any low-voltage wants: data, cameras, structured wiring, while the walls are open.
- Get us the plans early. Electrical on the critical path keeps the whole build moving.
