Why Texas Businesses Trust LMH for Commercial Electrical
Licensed, Insured Commercial Electricians
Commercial electrical work carries higher stakes than residential—more load, stricter code requirements, and greater liability. Our electricians are licensed and insured for commercial work, and we pull the proper permits for every job that requires one. You’re protected, your building is compliant, and your insurance stays valid.
Fast Response That Protects Your Revenue
A dark sign or a tripped panel costs you customers every hour. We prioritize commercial calls and respond the same day for urgent requests across the Houston area. Whether it’s a failed ballast, a blown circuit, or a sign that won’t light, we diagnose quickly and get you back to business.
Lighting Expertise That Lowers Your Bills
We install, repair, and upgrade interior and exterior commercial lighting, including LED retrofits that cut energy costs dramatically. Retail floors, parking lots, warehouses, offices—we light them efficiently and keep them lit. An LED retrofit often pays for itself in energy savings within two to three years.
Illuminated Signage Repair & Service
Your sign is your first impression and your nighttime advertising. We repair and maintain illuminated signage—LED conversions, failed transformers, broken channel letters, and wiring faults—so your business stays visible after dark. We coordinate around your hours to minimize disruption.
Panels, Circuits & Capacity for Growth
Adding equipment, expanding your space, or upgrading to higher-demand machinery? We assess your electrical load, upgrade panels, and install dedicated circuits sized for your needs. We make sure your building’s electrical infrastructure can handle what your business is doing today and what it’s planning for tomorrow.
One Contractor for HVAC & Electrical
Many commercial buildings juggle separate vendors for mechanical and electrical work. LMH handles both. When your rooftop HVAC unit needs electrical troubleshooting or your new equipment needs a dedicated circuit, the same trusted team handles it—faster coordination, fewer headaches, one point of contact.

What Houston-Area Business Owners Say
How We Handle Your Commercial Electrical Project
From the initial assessment to final testing and handoff, every step is documented and done to code — so your business stays powered and compliant.
We arrive, walk your property, and evaluate the electrical system or specific problem you’ve called about. For an outage, we trace the fault. For an upgrade, we measure your existing load and capacity. This step pinpoints exactly what’s needed before any work begins.
- Test panels, breakers, and circuits with a multimeter to locate faults or capacity limits
- Inspect lighting fixtures, ballasts, drivers, and signage transformers for failure points
- Review your building’s electrical load against current and planned equipment demands
- Identify any code or safety issues that need correction before work proceeds
- Document existing conditions with photos for your records and our scope of work
Once we’ve assessed the situation, we give you a clear, written scope: what we’ll do, what materials we’ll use, what it costs, and how long it will take. No surprises, no vague estimates. We’ll also flag any permits required and handle the filing for you.
- Present the work scope in writing with parts and labor itemized
- Explain permit requirements and inspection timing
- Recommend energy-efficient options (LED retrofits, smart controls) where they save you money
- Schedule work around your business hours to minimize disruption
Our licensed electricians perform the work to code, using quality materials and clean methods. Whether we’re repairing a sign, retrofitting lighting, or upgrading a panel, we work safely, protect your property, and keep your operation running wherever possible.
- Use quality, code-compliant materials and fixtures
- Follow lockout/tagout and safety procedures on every job
- Protect floors, fixtures, and inventory during the work
- Coordinate any required power-downs to off-hours when possible
Before we leave, we test everything: circuits energized correctly, lighting and signage operating, panels labeled, and loads balanced. For permitted work, we coordinate the inspection and make sure it passes the first time.
- Verify all circuits and fixtures operate correctly under load
- Confirm signage and lighting illuminate fully and consistently
- Label panels and document circuit assignments clearly
- Schedule and pass municipal inspection for permitted work
You’ll receive a written service report, photo documentation, and recommendations for keeping your electrical system reliable. For lighting and signage, we’ll suggest a maintenance schedule that catches failures before they go dark.
- Provide warranty terms on parts and labor
- Recommend a maintenance schedule for lighting and signage
- Suggest maintenance plan enrollment for priority dispatch
- Leave our emergency contact for after-hours issues

Frequently Asked Questions About Commercial Electrical
We handle commercial lighting installation and repair (interior and exterior, including LED retrofits), illuminated signage repair and service, panel replacements and upgrades, dedicated circuit installation, and electrical troubleshooting for commercial equipment and rooftop HVAC units. If your business has an electrical need, we can likely help—just call and ask.
Yes. We repair illuminated signage including failed LED modules, transformers, ballasts, channel letters, and internal wiring. A dark or flickering sign costs you nighttime visibility and advertising value, so we prioritize getting it lit again quickly. We can also convert older neon or fluorescent signage to efficient, longer-lasting LED.
Absolutely. LED retrofits are one of the highest-return upgrades a business can make—they cut energy costs, reduce maintenance, and improve light quality. We assess your existing fixtures, recommend the right LED solution, and handle the conversion. Most retrofits pay for themselves in energy savings within two to three years.
We prioritize commercial calls and respond the same day for urgent requests across the Houston metro. For a dark sign, a tripped panel, or a partial power outage, we dispatch the nearest available electrician quickly to diagnose and restore power.
Many commercial electrical jobs—panel upgrades, new circuits, significant additions—require a permit and inspection. We know the local requirements, pull the proper permits, and coordinate inspections so your work is fully compliant. For minor repairs, a permit usually isn’t required, and we’ll tell you up front either way.
Yes. If you’re adding equipment, expanding, or running into capacity limits, we assess your electrical load and upgrade your panel or add dedicated circuits sized correctly for the demand. We make sure your infrastructure can safely handle your current and future needs.
We do. We understand that power-downs and electrical work can disrupt operations, so we schedule work—especially anything requiring a power interruption—around your business hours whenever possible, including evenings and weekends for larger projects.
Yes. Our electricians are licensed and insured for commercial electrical work, and we carry the proper coverage and pull required permits. That protects your property, keeps your building code-compliant, and keeps your insurance valid.
We do, and it’s a real advantage. LMH provides both commercial HVAC and commercial electrical service, so when a rooftop unit needs electrical troubleshooting or new equipment needs a dedicated circuit, one team handles it. That means faster coordination, less downtime, and a single point of contact.
Yes. Our maintenance plans include priority dispatch, scheduled inspections, and parts discounts. For commercial lighting and signage especially, regular maintenance catches failing components before they go dark—protecting your visibility and avoiding emergency calls.
