Low-Voltage Pre-Wire and Network Installation for Custom Homes
Low-Voltage Subcontracting Services
CloudCentric is a managed IT provider in Mount Pleasant, South Carolina, serving businesses across Charleston and the Lowcountry. We work as the low-voltage and network subcontractor on new custom homes and whole-house renovations. Our services are designed for custom home builders, general contractors, architects, and renovation contractors in Charleston, Mount Pleasant, and the islands who need a low-voltage subcontractor. The scope covers network cable, Wi-Fi, cameras, door and gate access, phones, and the network rack. Drawings and the stage the build is at are enough to start. Call us at (844) 422-7000.
The Custom Home Market in Charleston
Charleston is one of three leading US custom-home markets named by Custom Builder magazine in January 2026. The Census Bureau reports the Charleston–North Charleston metro authorised 5,880 single-family building permits in 2025, against 6,708 in 2024 and 5,575 in 2023. A 2018 CEDIA study found 61 percent of architects use subcontractors for smart-home installation. To connect integrators with architects, designers, and builders, CEDIA opened a Design and Build Outreach department in April 2026.
Design and Schedule Coordination
The builder or general contractor owns the site schedule, and low-voltage work is booked into the windows the schedule sets. During the design stage, rack location, access point positions, camera positions, door hardware, gate conduit, and exterior pathways are placed during plan review, before framing, while drawings can still change. We size rack power and ventilation with the electrician at rough-in. Speaker wire and TV locations are coordinated with the AV contractor where one is on the job.
Rough-In and Pre-Wire Stage
Pre-wire, or rough-in, happens after framing and before insulation and drywall, in the same window as electrical, plumbing, and HVAC rough-in. At pre-wire, Cat6 is pulled to every room, TV position, ceiling access point, camera position, door, the gate, and the garage, and every run is labelled. Runs are pulled to positions with no device chosen yet, so the owner can add hardware later without opening walls. Fibre entry from the street and empty conduit for future runs are included in the pre-wire. Conduit goes to the dock, pool, gate, and detached buildings while the ground is open for trenching. Where spray foam is used, labels and capped conduit ends are checked before the insulation crew arrives. Renovations use the same stages, with access limited to walls, attics, and crawlspaces already open.
Coastal Installation Requirements
On homes raised over parking, the rack is placed on a living floor above flood level. Outdoor equipment and fixings on barrier-island houses are chosen for salt air.
Trim-Out, Final Commissioning, and Equipment Limits
Trim-out happens after paint: cables are terminated, wall plates and devices are mounted, and every run is tested and certified. In the final stage, the rack is built, access points, cameras, and door hardware are commissioned, and the owner's accounts and apps are set up. Handover documentation includes a written record of every run, labelled at both ends, with test results. The UniFi Dream Wall, a wall-mounted unit combining the gateway, switch, Wi-Fi, and camera recording, suits a builder's standard network package. There are specific regulatory limits for alarm systems. South Carolina licenses burglar and fire alarm contractors through the Contractor's Licensing Board. Fire alarm lines stay on a carrier or listed cellular line, and UniFi is not a monitored, UL-certificated alarm.
