Call Daniel Electric." url: https://danielelectric.multisites.ai/guides/commercial-electrical-services publisher: Daniel Electric phone: +1-817-481-8606 quote: https://danielelectric.multisites.ai/contact --- # Commercial electrical services for DFW facilities: maintenance, lighting, finish‑outs and new construction Commercial electrical work keeps a building safe, lit and running. It covers facility maintenance, repairs, lighting and parking lot lighting, tenant finish-outs and new construction. Plan maintenance before things fail, give your electrician clear drawings and access, and ask for a written scope and schedule. Homeowner guideUpdated October 21, 202610 min read ## Maintenance beats surprise failures NFPA notes that unexpected shutdowns happen every day because of equipment failure. A plan reduces them. ## Finish-outs need coordination A tenant finish-out depends on drawings, permits, inspection dates and the general contractor's schedule. ## Exterior lighting is a safety item Parking lot and security lighting affect the safety of staff, customers and vehicles. ## Backup power is a design question A generator, a transfer switch and the loads they serve must be planned together. Ask us about your site. ## What commercial electrical work do we do? Daniel Electric’s site lists commercial facility maintenance, parking lot lighting repair and replacement, underground circuits, tenant finish-outs and commercial new construction, from the ground up. The company states that it serves both commercial and residential customers. Tell us your building and your goal. Here is how those services map to common facility needs. Facility need What it involves Who usually asks Facility maintenance Inspect, test and repair electrical equipment on a schedule Property managers, owners, facility teams Repairs and troubleshooting Find the fault, fix the part, restore the circuit Any occupant Lighting Interior, exterior and security lighting, relamps and retrofits Owners, managers, tenants Parking lot lighting Poles, fixtures, photocells, circuits Retail, offices, apartments, churches Underground circuits Trenching, conduit and cable to poles, signs and outbuildings Owners, developers Tenant finish-out Power and lighting for a new or changed suite Tenants, landlords, general contractors New construction Full electrical systems from the ground up Developers, general contractors The company is family owned and operated, based in Southlake, and says it has served the area since 1988. Its Texas license is TECL #21005. For commercial customers, a license check is the first step. TDLR states that anyone who performs or offers to perform non-exempt electrical work in Texas must be licensed and perform that work through a licensed electrical contractor. ## How do parking lot and exterior lights get repaired? Parking lot lighting work starts with finding why lights are out: a failed lamp or fixture, a photocell, a damaged cable or a tripped circuit. Daniel Electric lists running new pulls, repairing light poles, installing energy-efficient lighting and troubleshooting electrical and lighting issues on its parking lot lighting page. A dark lot is a safety issue for staff, visitors and vehicles. It can also raise liability questions for the owner. Do not wait for a full outage before you act. A pattern of outages often points to a common cause. What you see Likely area First check One light out Lamp, fixture or driver Replace the part, then watch it Lights on one pole line out Circuit, breaker or cable Check the circuit and the splices Lights stay on in the day Photocell or controller Check the sensor and its power Lights flicker or cycle Failing driver, ballast or connection Find the weak part Whole lot dark Panel, contactor, main feed or utility Check the feed and the controls Pole leans or has damage Pole base, foundation or impact Treat as a safety hazard An LED retrofit can cut energy use and maintenance. The Department of Energy notes that LED sources are inherently dimmable and can be integrated with sensors and controls, which can add savings through occupancy sensing, daylight harvesting and local control of light levels. For lot lighting, the choice depends on the poles, the circuit and the light levels you need. Read the detail on our [parking lot lighting repair](https://danielelectric.multisites.ai/parking-lot-lighting-repair) service page, and see our guide to [parking lot lighting repair](https://danielelectric.multisites.ai/guides/parking-lot-lighting-repair-guide). For the broader lighting picture, see our pillar on [lighting installation and LED retrofits](https://danielelectric.multisites.ai/guides/lighting-installation-and-led-retrofits). Stay away from a pole that has been hit or is leaning, or a lamp that hangs by a cable. If a line is down, stay clear and call 911 and the utility. ## What should a facility manager schedule for preventive maintenance? Schedule inspections and tests by equipment type, age and use, and keep a written record. NFPA 70B sets requirements for a program for maintaining electrical equipment. NFPA notes that unexpected shutdowns happen every day because of equipment failure, which is why a plan is cheaper than a surprise. NFPA also states that moving 70B from a recommended practice to a standard provides more enforceability for what must be done for electrical equipment maintenance. Ask your electrician whether your insurer, lender or lease refers to it. We do not tell you which edition or section applies to your site, because that depends on the facts. We tell you to ask. A maintenance plan starts with a list. 1. **Inventory.** Write down panels, [panelboards](https://danielelectric.multisites.ai/glossary/panelboard), switchgear, transformers, disconnects, lighting controls and emergency lighting. 2. **Condition.** Note age, location, damage, heat, moisture and past trouble. 3. **Criticality.** Mark the equipment that would stop the business if it failed. 4. **Interval.** Set a visit schedule for each group. 5. **Tests.** Choose the tests that fit, such as visual checks, thermal imaging and tightness checks. 6. **Record.** Keep dated notes, photos and findings. 7. **Follow-up.** Fix what the visit finds, and note what was done. Here is a simple way to sort the work. Frequency Examples Done by Monthly Walk-through, emergency light and exit sign test, look for tripped breakers Facility staff Quarterly Look at panels from outside, check lighting controls, check exterior lighting Staff, with an electrician for issues Yearly or by plan Inspect and test equipment, thermal imaging, torque checks Licensed electrician After an event Storm, outage, water, fire, impact Licensed electrician The intervals above are examples of how to organize a plan. They are not a rule for your building. Your equipment maker’s guidance and your electrician’s findings set the real schedule. Never open a panel or switchgear yourself. Live parts sit behind the covers, and arc flash can cause severe injury. Staff should look from outside and report what they see. Our guide on [commercial electrical maintenance](https://danielelectric.multisites.ai/guides/commercial-electrical-maintenance) goes into more detail. ## What does a general contractor need from the electrician on a tenant finish-out? A general contractor needs a clear scope, a schedule, permit handling and inspection dates. A [tenant finish-out](https://danielelectric.multisites.ai/glossary/tenant-finish-out) turns a shell or a former suite into a space for a business. Daniel Electric lists tenant finish-outs, and commercial new construction from the ground up, among its commercial services. The electrician’s part is power, lighting and the circuits that serve the new layout. The details depend on the plans. Use this list when you plan one. Item What to settle Why it matters Drawings Current plans and any changes The scope follows the drawings Existing panel Capacity, space and condition New loads may need a new panel or feeder Lighting Fixtures, controls and light levels Affects layout and ceiling work Power Outlets, dedicated circuits and equipment loads Kitchen, server and machine loads set the circuits Emergency lighting and exit signs Location and power Safety and code items Permit Who applies, and which city Work can stop without it Inspection Dates and access Rough-in and final inspections Schedule Order of trades Electrical work sits between framing and finish Utility Meter, service size, timing Utility steps can set the critical path Tell the electrician about any special equipment early. Medical, kitchen, data and manufacturing equipment can change the plan. If the space will have EV charging, say so. The EV charger pillar covers business and multifamily charging in more detail. Code editions matter on a commercial job. TDLR adopted the 2026 National Electrical Code as the state electrical code, effective September 1, 2026. City pages vary. For example, the City of Southlake’s page lists the 2023 National Electrical Code through Ordinance No. 1280. Ask the inspection office which edition it applies on your permit date. ## What about backup generator systems for businesses? A backup generator is a system, not just a machine. It needs the right size, a transfer switch, a fuel and exhaust plan, a safe location and permits. Daniel Electric’s site mentions backup generator systems for commercial customers. Ask us what we can do for your site. We list generator installation here only as a topic to discuss, not as a service page. The key parts are these: - **The loads.** Which circuits must stay on in an outage? Life safety, refrigeration, servers, phones and security are common. - **The size.** The generator must carry those loads, including the startup surge of motors. - **The [transfer switch](https://danielelectric.multisites.ai/glossary/transfer-switch).** It moves the building from utility power to generator power and back, and keeps the generator from feeding power to the utility lines. - **Fuel and exhaust.** Natural gas, propane and diesel each have placement and supply questions. - **Location.** Generators must sit where exhaust cannot enter a building. - **Testing.** Run and test the system on a schedule, under load. Back-feeding power into a building without a transfer switch can kill utility workers and damage equipment. Never connect a generator to a building’s wiring without a transfer switch installed by a licensed electrician. Portable generators have their own rule. The Consumer Product Safety Commission says never to use portable generators indoors or in garages, basements or sheds. Generator exhaust contains carbon monoxide. ## What can staff do every day to keep a building electrically safe? Staff can spot problems early without opening anything. Keep the space around panels clear, report warm or buzzing equipment, and test emergency lights and exit signs on the schedule your electrician sets. Staff should never repair live equipment. A short list for a manager to share with the team: - Keep a clear path to every electrical panel and shutoff. Do not stack boxes in front of them. - Label panels and breakers so that anyone can find the right circuit in a hurry. - Report breakers that trip, lights that flicker, outlets that feel warm, and any burning smell. - Do not run extension cords as permanent wiring, and do not daisy-chain power strips. - Keep water and other liquids away from electrical equipment. - Do not reset a breaker over and over. A repeated trip is a warning. - Keep a short list of who to call, with the electrician, the property manager and the utility. If a problem involves smoke, fire or a person who may have been shocked, call 911. Do not touch a person who is still in contact with live power. Cut power at a safe disconnect if you can reach it without risk, or wait for responders. ## How do I request service and what should I have ready? Call or use the quote form, and describe the site. The more detail you give, the faster we can plan the visit. Daniel Electric states that it gives free quotes on new installations, and we give the scope in writing. Have these ready: 1. **The address,** and the type of building: office, retail, restaurant, warehouse, church or other. 2. **The problem or project,** with photos if you can. Show panels from outside with the doors closed. 3. **Who can give access,** and the hours when the work is allowed. 4. **Plans,** if the job is a finish-out or new build. 5. **The deadline,** and any hard dates such as an opening or an inspection. 6. **The decision maker,** and anyone who must approve the scope, such as a landlord or lender. Say whether the problem affects safety. Dark stairs, exposed wiring, burning smells and sparking are urgent. If there is fire or smoke, leave and call 911. If a power line is down, stay clear and call 911 and the utility. We do not publish emergency hours or promise a response time on this page. Call (817) 481-8606 and ask what we can do for your situation. See our pillar on [emergency electrical help and troubleshooting](https://danielelectric.multisites.ai/guides/emergency-electrical-help) for first steps while you wait. ## What should I look for when I hire a commercial electrician? Look for a Texas license, written scope, clear permit handling, references you can call, and a plan for access and schedule. Check the license on the TDLR site. Ask who does the work and who is accountable on site. A short vetting list: - **License.** Confirm the license on TDLR. Daniel Electric lists TECL #21005. - **Scope.** The quote should state what is included and what is not. - **Permit and inspection.** Who handles both? - **Schedule.** Start date, steps and finish date, with the dependencies. - **Safety.** How the crew protects occupants and property while working. - **Warranty.** Read the written terms. Daniel Electric’s warranty page states the terms for workmanship and parts. - **Record.** Ask for the test results, the permit card and the as-built notes at the end. Daniel Electric says its electricians are drug and background tested. Ask any contractor how they screen their crews. ## Next step To plan a commercial project or a maintenance program, see our [commercial electrician](https://danielelectric.multisites.ai/commercial-electrician) page.

Daniel Electric's site lists commercial facility maintenance, parking lot lighting repair and replacement, underground circuits, tenant finish-outs, and commercial new construction from the ground up. Tell us the building and the problem, and we will plan a visit and give you a written quote. ### What is a tenant finish‑out, and what does the electrician do? A tenant finish-out turns a leased shell or an old suite into a space ready for a business. The electrician plans power, lighting, panels and circuits for the new layout, pulls permits, installs the work and schedules inspections with the general contractor. ### How often should a business schedule electrical maintenance? The right interval depends on the equipment, its age, its use and the maker's guidance. NFPA 70B sets requirements for an electrical maintenance program. Ask your electrician to build a schedule from your equipment list, and keep a written record of each visit. ### Do you repair parking lot lights? Yes. Parking lot lighting repair is one of Daniel Electric's service pages. The company lists running new pulls, repairing light poles, installing energy-efficient parking lot lighting, and troubleshooting electrical and lighting issues. Call (817) 481-8606 with the site address and what you see. ### Do you install backup generators? Ask us. Daniel Electric's site mentions backup generator systems, but we do not list generator installation as a service page here. A generator needs a transfer switch, correct sizing and a fuel and exhaust plan. Call (817) 481-8606 and describe your site, and we will say what we can do. ### Do I need a licensed electrician for commercial work in Texas? Yes. TDLR states that anyone who performs or offers to perform non-exempt electrical work in Texas must be licensed and must perform that work through a licensed electrical contractor.
