National Boiler Service Is Now National — And Here's What That Means for You

For over 35 years, our clients have known us as National Boiler Service: a company built on technical precision, safety-first execution, and a commitment to showing up when it matters most. That reputation isn't changing. Our name is.

We are now National.

This isn't a rebranding for its own sake. It's recognition of a reality our clients have already been living: we have been delivering far more than boiler services for years. Today, we're making that official, and building the infrastructure to do it at greater scale.

A single partner. Four divisions. One standard of excellence.

Under the National name, we operate as a full-stack industrial contractor across four integrated divisions:

Boiler Services The foundation we've built over three decades. We handle repairs, maintenance, and installations across a full range of boiler types, including recovery, package, fossil-fired, and Heat Recovery Steam Generators (HRSG). This is where our legacy lives, and where our standards were set.

Mechanical Services Precision repairs, maintenance, and installation of industrial piping, equipment, and components. For clients who need mechanical work executed with the same rigor they've come to expect from our boiler teams, this division delivers exactly that.

Construction Services Full-scope capital project support from pre-construction through execution and project management. We don't just show up for maintenance windows. We build.

Specialty Services Chimney and stack inspection and repair, vessel and tank design, installation and repair, and specialized welding services. Work that demands a level of expertise most contractors can't offer. We can.

What this means in practice: industrial project owners, plant managers, and EPCs can consolidate complex, multi-scope work under a single accountable partner, eliminating the fragmentation, coordination overhead, and accountability gaps that come with managing multiple contractors.

Built for the industries that can't afford to stop.

National operates at the intersection of complexity and consequence. We serve clients in Pulp & Paper, Power Generation, Petrochemical, and Industrial Manufacturing: environments where downtime is measured in lost production, where safety is non-negotiable, and where the margin for execution error is zero. That's the standard we've operated at since 1989, across more than one million manhours performed annually. See how we serve each industry.

The same people. Significantly more capability.

“We’re excited to introduce the National brand — a reflection of who we’ve already become and where we’re headed. While our name is evolving, the strength of our team remains the foundation of everything we do. Our clients will continue working with the same experienced professionals they’ve trusted for decades, backed by a deep bench of long-tenured talent. With expanded service capabilities, we’re now able to deliver an even broader range of solutions — all while maintaining the same high level of service, reliability, and reputation that National has always been known for.”

Michael Hannaford, CEO, National

Our promise remains the same: to be the single, reliable partner you can rely on for execution at the highest standard. We look forward to continuing to serve you under the National name, bringing expanded capabilities and the same dedicated teams to every project.
