Our Process

Step 1: Design
We plan drop counts, riser paths, and rack locations against your floor plan and IT requirements.
Step 2: Rough-in
Low-voltage rough is run parallel to electrical to minimize trips and openings in occupied buildings.
Step 3: Termination and test
Every drop is terminated to industry standard and tested with a Fluke or equivalent certifier; results are provided to the owner.
Step 4: Handoff
Patch panels are labeled, rack elevations are documented, and your IT vendor can plug in and go.

Frequently Asked Questions

Do you install fire alarm systems?

South Carolina requires a separate fire alarm license. We coordinate with licensed fire alarm installers on our projects and handle all conduit rough-in for the fire alarm cabling.

Can you install cabling in an occupied building?

Yes. Most low-voltage work is done during business hours from above accessible ceilings, or after hours where noise or ceiling access is disruptive.

Do you provide test results for each data drop?

Yes. Every Cat6/6A drop is certified with a professional test set, and the results are turned over to the owner as a PDF.

Equipment & planning guide · the Charleston Lowcountry

Structured cabling, media wiring, and network reliability

Use this guide to compare options before booking. For this work, the important starting points are the equipment to connect, cable pathways, network performance goals, and separation from power wiring. Exact equipment selection follows an assessment of your property, the manufacturer’s instructions, and applicable local requirements.

Choose the cable for the intended network

Category 6 and Category 6A cabling differ in performance characteristics and installation considerations. The required speed, route length, interference environment, and equipment determine the appropriate choice. A patch cord alone cannot upgrade a lower-performing permanent link. Fiber may be suitable for certain longer or electrically isolated connections, while coaxial cable still has a role for some services and media systems.

The pictured Leviton Category 6A patch cord is an actual manufacturer product. It illustrates a finished connector and cable assembly, not a certification result for a building’s wiring. Cabling systems rely on compatible cable, connectors, termination practices, and testing. Avoid choosing solely by a marketplace claim of very high speed. Explain the network equipment you plan to use so the proposed wiring supports a real need rather than an unnecessary product upgrade.

Permanent links, patch cords, and labeling

A permanent link connects fixed termination points; patch cords connect devices to those points. Keeping these roles clear helps make future changes easier and protects fixed cable from repeated handling. Suitable jacks, patch panels, strain relief, bend radius, and routing all influence reliability. A cable can appear connected and still perform poorly because of damaged conductors or unsuitable terminations.

Agree on labeling conventions before installation. Room names, outlet identifiers, and patch-panel positions should correspond so a future technician can trace a connection without opening every wall plate. Ask whether the scope includes basic continuity verification or performance testing appropriate to the intended system. Those are not interchangeable promises. Keep results and as-built information where the person managing the network can find them.

Access points, televisions, and power requirements

Network access points, cameras, and other devices may use power over Ethernet when the equipment and cabling support it. Their placement should reflect coverage, access, and operating conditions. Running a cable to a corner that is convenient for construction may be less useful than placing the device where the system design needs it. Device selection and network configuration remain separate tasks unless explicitly included in the scope.

Television installations can require both power and low-voltage connections. Ordinary flexible power cords should not be concealed in walls as a substitute for an approved wiring arrangement. The pictured Leviton receptacle represents the power side of the installation, not the data connection. Discuss a suitable outlet location, cable pathway, mounting support, and service access. A clean finish should not come at the expense of inaccessible connections or improvised cord routing.

Protect pathways and plan future changes

Low-voltage wiring still needs appropriate physical support, routing, firestopping where required, and attention to environmental exposure. Power and communications wiring cannot simply share every box or pathway. Existing conduits may be unsuitable, full, or intended for another purpose. An assessment should identify the route and any limitations before a promise is made to hide every cable.

A spare pathway or an accessible termination location can be more valuable than installing excessive cables without a plan. For commercial premises, coordinate access with tenants, occupied work areas, security, and other trades. The handover should identify what was installed and tested and which tasks remain with the network or audiovisual provider. That division avoids assuming an electrician’s cabling work also includes internet service, Wi-Fi optimization, or equipment configuration.

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 equipment to connect, cable pathways, network performance goals, and separation from power wiring 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

Mark router, access-point, workstation, and television locations.
Identify whether devices need Ethernet, fiber, coaxial cable, or power over Ethernet.
Discuss concealed routes, labeling, and finish repairs.

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.
