More About Our Expertise
With 40+ years of experience, Thomac Services is a trusted name in industrial leak repair. We help reduce downtime, maintain safety, and extend equipment life — all without interrupting your operation.
We stop leaks fast—whether it’s steam, water, chemical, or valve-related. Our team designs and applies custom containment systems for each situation, delivering solutions that withstand pressure and temperature extremes.
If you’re facing a leaking valve gland, damaged gasket, or corroded flange, we can help—without interrupting your production line.
We repair pressure piping systems under full operating conditions. This includes flanges, elbows, expansion joints, unions, and pinholes.
Because every second counts, our technicians bring the tools and training to resolve these problems on-site and without delay.
Our bolt tensioning services are critical for maintaining high-pressure integrity. Using calibrated torque tools and hydraulic tensioners, we apply uniform force across all fasteners.
This prevents uneven gasket loading, minimizes future leaks, and ensures structural reliability—all while your system remains online.
Our in-house engineering team designs and manufactures custom containment devices for complex and high-risk leak situations. All containment systems are built in our machine shop, tested for safety, and registered with a Canadian Registration Number (CRN) where required.
These devices are used to control leaks from valve bodies, flange assemblies, pipe welds, packing glands, and other pressurized components. We tailor each device to the specific geometry, temperature, and pressure profile of the equipment, ensuring safe installation and reliable performance—even in hazardous environments.
Our steam loss survey services help clients identify and address inefficiencies in their steam distribution systems. Using specialized instruments, we detect live leaks, faulty traps, and degraded insulation, providing an itemized report that outlines the energy cost of each issue.
These surveys are a cost-effective way to reduce energy waste, improve system efficiency, and plan for targeted maintenance. Common clients include food processors, chemical manufacturers, power plants, and pulp and paper facilities that rely on steam for operations.
Thomac provides comprehensive valve lapping and remediation services to support safe and efficient plant operation. Our inline valve lapping services restore the sealing surfaces of gate and slide valves, improving flow control and extending valve life.
We also perform asbestos abatement and remediation, including removal and encapsulation of hazardous materials in compliance with all provincial safety and environmental regulations. These services are often performed in tandem during shutdowns or repair projects to ensure safe working environments and long-term system integrity.
