What types of fleets do you service?

We service light, medium, and heavy-duty diesel truck fleets, including box trucks, semis, and service vehicles across commercial and industrial sectors in Houston and surrounding regions. Whether you manage a logistics fleet, construction vehicles, or municipal trucks, we have the expertise to support your operational needs. Our facility is fully equipped to handle both routine and complex service requirements.

How often should fleet maintenance be scheduled?

Typical fleet maintenance is scheduled every 10,000 to 20,000 miles, but it can vary depending on vehicle use, age, and routes, especially with demanding terrain like West Virginia's hills. Fleets with frequent stop-and-go driving or cross-state hauling may require more frequent intervals. We help customize service timelines based on vehicle diagnostics and operating conditions.

Do you offer on-site fleet maintenance?

Yes, depending on fleet size and location. We serve numerous Houston metro clients and can coordinate field service visits for larger fleets in areas such as Spring or Sugar Land. Our mobile service units are equipped to perform diagnostics, fluid changes, and light repairs, reducing the need for downtime and towing.

Are your fleet maintenance services DOT-compliant?

Absolutely. We strictly adhere to DOT regulations and ensure your fleet is inspection-ready for both Texas and federal transportation authorities. Our services include brake inspections, lighting checks, and emissions compliance—everything needed to pass audits and avoid penalties. We stay updated on changing regulations to keep your fleet ahead.

How do you keep track of service intervals?

We maintain detailed digital records and notify clients when upcoming maintenance is due, supporting logistics managers in locations such as The Woodlands and Huntington with timely reminders. Our software logs all repairs, parts replaced, and mileage intervals, making scheduling easy and audit preparation seamless. You’ll never miss a critical maintenance checkpoint.

Do you service diesel and gas vehicles?

While our specialty is diesel repair, we also offer maintenance for gasoline-powered fleet vehicles as part of our integrated fleet service plans in the Houston and surrounding areas. This flexibility enables mixed-fleet operators to streamline their services under one roof. Our technicians are trained to handle both fuel types with equal precision.

What brands and models do you support?

We work with major fleet brands, including Freightliner, International, Kenworth, and Peterbilt, providing parts and systems expertise across various commercial models. Our shop offers a wide selection of OEM and high-quality aftermarket components, ensuring quick turnaround and reliability. Whether your fleet is standardized or mixed, we have the resources to maintain it effectively.

Can you customize maintenance plans for our fleet?

Yes. Our team will assess your fleet’s operational patterns and develop a maintenance schedule tailored to your needs, whether you're based in Katy or have units reaching Parkersburg. We factor in load weight, mileage, usage frequency, and driving conditions. A tailored plan ensures efficiency, cost control, and reduced risk of mechanical failure.

Given the demands placed on commercial vehicles, especially in oilfield transport, logistics, or construction industries across Texas and West Virginia, preventive maintenance is not a luxury—it's a necessity. When trucks fail, business stalls. Our mission is to minimize that risk and keep your fleet moving with maintenance strategies built for the road ahead.

Our Fleet Maintenance Services

Preventive Maintenance Inspections (PMI)

Our PMI service includes fluid checks, filter inspections, brake testing, and a complete multi-point inspection tailored to your vehicle usage. Clients trust our structured PM routines to stay ahead of unexpected breakdowns. We also inspect belts, hoses, suspension, and lights to ensure every component is road-ready. By identifying potential issues early, we reduce downtime and extend the lifespan of your fleet assets.

Engine Diagnostics and Tune-Ups

Using advanced diagnostic tools, we quickly identify issues affecting engine performance. This ensures smoother operation, especially for long-haul routes. Our technicians scan for error codes, inspect sensors, and verify emissions systems to ensure compliance and optimal performance. Whether it's a faulty injector or EGR valve, we quickly identify the root of engine concerns.

Transmission and Drivetrain Maintenance

We inspect and service gear systems, transfer cases, and drivetrains to prevent overheating or gear failure, helping maintain power transmission under heavy traffic and high temperatures. Our technicians address issues like fluid degradation, clutch wear, and axle imbalance. For fleets operating in hilly areas, drivetrain health is crucial for maintaining towing capacity and powertrain integrity.

Brake System Services

From air brake testing to complete system replacements, we prioritize safety for fleets traversing highways and mountain routes. We inspect pads, drums, rotors, lines, and air compressors to ensure responsive stopping power. Brake failure is one of the top causes of roadside violations, which is why timely service is essential for both safety and DOT compliance.

Fluid Replacements and Oil Changes

We perform complete fluid replacements—transmission, coolant, brake, and differential—based on manufacturer specifications and real-world fleet conditions. Our service also includes filter replacements and fluid analysis to detect early signs of contamination or system wear. Maintaining proper fluid levels reduces friction, prevents overheating, and boosts overall mechanical performance.

Tire Rotation, Balancing, and Alignment

Proper tire care helps reduce wear and improve fuel efficiency. Our team provides alignment and rotation services tailored for city-wide deliveries. Uneven tread wear can lead to blowouts and lower fuel economy, especially on long-distance routes. We utilize computerized systems for precise alignment and balancing, which maximize traction and stability.

Benefits of Professional Fleet Maintenance Services

Maximized Vehicle Uptime

Regular fleet maintenance significantly reduces the likelihood of unexpected breakdowns. This ensures that your commercial vehicles remain operational and on schedule, minimizing disruptions in service delivery. Maximizing uptime is crucial for logistics, construction, and service companies that rely on reliable daily transportation to fulfill operational commitments and meet client expectations.

Lower Long-Term Repair Costs

Preventive maintenance detects early signs of wear and mechanical issues before they escalate. Addressing problems proactively reduces the need for expensive emergency repairs, component failures, and vehicle replacements, enabling fleet managers to allocate budgets more effectively and extend the lifecycle of their trucks and equipment.

Improved Fuel Efficiency

Fleet maintenance encompasses critical services, including engine tune-ups, fluid checks, and filter replacements. These practices keep engines running smoothly and efficiently, lowering fuel consumption and emissions. Over time, even small improvements in fuel economy can deliver significant cost savings, especially for high-mileage or regional fleet operations.

Enhanced Safety and Compliance

Routine inspections and system diagnostics help maintain compliance with DOT and FMCSA regulations. Maintenance ensures safe braking, proper lighting, and roadworthiness, reducing accident risks and avoiding costly fines or penalties during roadside inspections and regulatory audits.

Extended Equipment Lifespan

Consistent maintenance improves overall vehicle health. Regular oil changes, transmission servicing, and proper tire care help prevent premature wear and extend the lifespan of major components. This enables fleet operators to maximize their return on investment and delay the capital costs of vehicle replacements.

Stronger Operational Reliability

Fleet reliability supports consistent delivery schedules and client satisfaction. Whether transporting goods, materials, or personnel, a well-maintained fleet minimizes disruptions. Operational reliability enhances your brand reputation, supports contract fulfillment, and provides your business with a competitive edge in service-driven industries.
