Electrical Wiring Services in Atlanta, GA

Licensed Electrical Wiring Contractors Serving Metro Atlanta

Whether you're building a new home, renovating an older property, or simply need additional circuits to keep up with modern electrical demands, the wiring behind your walls is the foundation of a safe and functional electrical system. M.D. Contracting Solutions provides professional electrical wiring services for homeowners and businesses throughout Atlanta, Marietta, Smyrna, Kennesaw, Roswell, Acworth, Alpharetta, Woodstock, and the surrounding metro area.

New Construction Wiring

Building a new home or commercial space requires a complete electrical wiring system designed from the ground up. We work with builders, general contractors, and homeowners to plan and install wiring that meets code requirements and supports the property's electrical needs — from lighting circuits and outlet placement to dedicated appliance circuits, HVAC connections, and structured wiring for data and communications. We handle both rough-in wiring during framing and final device installation after drywall.

Whole-Home Rewiring

Older homes — especially those built before the 1970s — often have wiring that cannot safely handle today's electrical loads. Warning signs include frequently tripping breakers, flickering or dimming lights, warm or discolored outlets, two-prong (ungrounded) outlets, and a burning smell near outlets or switches. A whole-home rewire replaces all existing branch circuit wiring with modern copper conductors, adds proper grounding throughout, and brings the entire system up to current code. This is one of the most important safety upgrades you can make to an older home.

Knob-and-Tube Wiring Replacement

Knob-and-tube wiring was the standard installation method from the 1880s through the 1940s. It uses ceramic knobs and tubes to route individual conductors through wall and ceiling cavities without a ground wire. While not inherently dangerous in its original condition, knob-and-tube wiring deteriorates over time, cannot safely support modern electrical loads, and becomes a serious fire hazard when blown-in insulation is added over it. Most insurance companies in Georgia either refuse coverage or charge higher premiums for homes with active knob-and-tube wiring. We remove and replace it with modern, grounded wiring.

Aluminum Wiring Remediation

Aluminum branch circuit wiring was used in many homes built between the mid-1960s and mid-1970s. Aluminum expands and contracts more than copper, which can cause connections to loosen over time and create hot spots — a documented fire hazard. We remediate aluminum wiring using approved methods including copper pigtailing with COPALUM or AlumiConn connectors at every connection point, or full replacement with copper wiring depending on the scope and condition of the existing installation.

Circuit Additions

Adding circuits is one of the most common electrical wiring requests we handle. Whether you need a dedicated 20-amp circuit for a kitchen appliance, a 240-volt circuit for an electric dryer or workshop equipment, additional outlet circuits in a finished basement, or new circuits for a home office setup, we run properly sized wiring from your panel to the new location, install the appropriate breaker, and ensure everything is permitted and inspected.

Home Addition & Renovation Wiring

Adding a room, finishing a basement, converting a garage, or renovating a kitchen all require new electrical wiring. We design and install wiring for additions and renovations that integrates with your existing electrical system while meeting current code requirements for outlet spacing, AFCI/GFCI protection, lighting, and dedicated circuits. We coordinate with your general contractor to ensure electrical rough-in aligns with the construction schedule.

Garage & Workshop Wiring

Detached garages, workshops, and outbuildings need properly sized electrical feeds and dedicated circuits for tools, compressors, welders, and other high-draw equipment. We run underground or overhead service feeds from your main panel, install a subpanel if needed, and wire individual circuits for lighting, outlets, and specific equipment. We also install 240-volt outlets for equipment that requires it.

Low-Voltage & Structured Wiring

Beyond standard power wiring, we install low-voltage structured wiring for home networks, security systems, audio/video distribution, and smart home infrastructure. Running dedicated data cables, coaxial, and speaker wire during construction or renovation is far more reliable than relying solely on wireless connections, especially for home offices, media rooms, and security camera systems.
