licensed electrical maintenance
prevent replacement of Your Critical Power Assets
We move beyond surface-level “visual checks.” Our NETA-trained technicians perform deep-level diagnostics on the core components of your infrastructure, adhering to NFPA 70B mandatory maintenance intervals. We ensure every piece of hardware is restored to a “Like New” condition of maintenance.
Switchgear & Motor Control Centers (MCCs)
We perform comprehensive insulation resistance testing (Megger) and contact resistance testing (Ductor) on all main breakers. Our process includes meticulous vacuum-cleaning of cubicles to remove carbon tracking, followed by ultrasonic inspection and calibrated torque-verification of all busbar connections to prevent heat-related failures.
Transformers & Variable Frequency Drives (VFDs)
For liquid-filled units, we perform dissolved gas analysis (DGA) and dielectric strength testing to identify internal winding degradation. For VFDs, we analyze harmonic distortion and DC bus health, ensuring your drives aren't injecting "dirty power" back into your Houston facility's grid and causing premature motor failure.
UPS Systems & Backup Power Infrastructure
We provide full-string battery impedance testing and load bank testing to guarantee your Uninterruptible Power Supply (UPS) performs during an ERCOT grid event. Our service includes the testing of Automatic Transfer Switches (ATS) and paralleling switchgear to ensure a seamless, sub-cycle transition to backup power.
Allied Contractors: Houston's trusted technicians
From mandatory NFPA 70B compliance to high-level thermal diagnostics, Allied Contractors are the definitive choice for electrical preventive maintenance in Houston. Secure your facility’s future with the team that knows the local grid and local challenges best.
The Science of Failure Prevention
Advanced Infrared & Ultrasonic Testing
As a premier provider for electrical preventive maintenance in Houston, we move beyond reactive repairs into Predictive Maintenance. Our diagnostic suite identifies “silent” electrical anomalies—stressors that exist even while your equipment appears to be operating within normal parameters. By identifying these faults in the incipient stage, we eliminate the risk of catastrophic arc flash events and unplanned facility shutdowns.
Level II Infrared Thermography & Thermal Analysis
We utilize high-resolution radiometric imaging to map the thermal signature of your distribution system under load. By identifying "thermal gradients" or hot spots caused by phase imbalances, unseated fuses, or compromised internal breaker contacts, we provide a localized roadmap for repairs before thermal runaway occurs.
Airborne & Structure-Borne Ultrasonic Detection
Since thermal imaging cannot "see" through solid enclosures, we utilize ultrasonic acoustic sensors to listen for the high-frequency signatures of arcing, tracking, and corona. This is critical for Houston facilities, as high humidity can cause internal tracking across insulators long before a heat signature is detectable on the cabinet surface.
Power Quality & Harmonic Distortion Analysis
We deploy transient recorders to capture high-speed data on voltage sags, swells, and total harmonic distortion (THD). This analysis is essential for protecting sensitive PLC controls and server racks from "dirty power" fluctuations within the ERCOT grid, allowing us to recommend precise power factor correction and surge suppression strategies.

Frequently Asked Questions: EPM in the Texas Gulf Coast
Why is electrical preventive maintenance (EPM) critical for Houston facilities?
In the Houston metro, electrical infrastructure faces extreme “Service Conditions” due to high ambient temperatures and the corrosive, salt-laden air of the Texas Gulf Coast. Without a dedicated EPM program, these factors accelerate the oxidation of copper busbars and the degradation of cable insulation. Regular maintenance at facilities in Pasadena, Deer Park, and the Port of Houston is not just about reliability—it’s about preventing catastrophic moisture-induced tracking and arc flash events.
What are the new mandatory NFPA 70B requirements for 2026?
As of the most recent regulatory cycle, NFPA 70B has transitioned from a “recommended practice” to a mandatory standard for the maintenance of electrical systems. Houston facility managers are now required to maintain a formal, documented Electrical Maintenance Program (EMP). Allied Contractors specializes in providing the NETA-certified testing and “Condition of Maintenance” documentation required to satisfy insurance audits and OSHA safety inspections.
How does Houston’s humidity affect my switchgear and MCCs?
Houston’s high humidity increases the conductivity of surface contaminants (dust and carbon), which leads to a phenomenon known as “tracking.” This allows electricity to crawl across insulators, eventually causing a phase-to-ground fault. Our electrical preventive maintenance in Houston includes precision vacuum-cleaning and the application of anti-tracking coatings to protect Motor Control Centers (MCCs) in non-conditioned industrial environments.
How often should I perform infrared thermography on my Houston electrical panels?
For most industrial and commercial facilities in the Energy Corridor and Westchase districts, we recommend a Level II Infrared Inspection at least once per year under peak load conditions (typically during the high-demand summer months). However, for mission-critical data centers or high-cycle manufacturing plants in Sugar Land and Katy, semi-annual scans are the industry standard for identifying incipient faults before they manifest as outages.
Does your EPM service cover compliance for the ERCOT grid fluctuations?
Yes. With the increasing volatility of the ERCOT grid, Houston businesses often face voltage sags and harmonic distortion. Our EPM includes Power Quality Analysis, where we deploy transient recorders to monitor your “dirty power” levels. We then provide engineering solutions—such as surge suppression and harmonic filtering—to protect your sensitive PLC controls and server racks from grid-induced fatigue.
Which areas of Greater Houston does Allied Contractors serve?
We maintain a localized fleet of technicians providing 24/7 coverage across the entire 9-county Houston metro. This includes the Energy Corridor, Downtown, The Woodlands, Humble, Conroe, Pearland, and the Baytown/La Porte industrial zones. Our strategic positioning allows us to respond to emergency troubleshooting calls within the hour for most “near me” searches.
Can an EPM program lower my facility's insurance premiums in Texas?
In many cases, yes. Most major industrial insurers now require proof of a compliant NFPA 70B maintenance program to maintain coverage. By providing certified reports of your infrared scans, ultrasonic testing, and breaker injections, we help Houston business owners demonstrate “due diligence,” which can lead to lower premiums and the prevention of “denial of claim” following an electrical incident.
