TSSA Certification: More Than a Checkbox

When safety, reliability, and compliance are non-negotiable, TSSA Certification should never be treated as a formality. Unfortunately, some contractors still cut corners submitting bids without proper credentials or relying on licensed subcontractors to carry their work. At Patrick Mechanical Ltd., we take a different approach. Our certification isn’t just a requirement, it’s built into how we protect your project from day one.

Why Unlicensed Work Still Happens

Despite the risks, unlicensed or partially licensed work still shows up on job sites. Often, it goes unnoticed until a code violation, equipment failure, or audit flags the issue. By then, the damage is done.

Here’s where problems usually begin:

  • Contractors outsource certified tasks without disclosing it
  • Unlicensed workers perform regulated work during tight timelines
  • TSSA-required documentation is missing or incomplete

These shortcuts put clients at risk—not just legally, but operationally.

What Full-Scope TSSA Certification Actually Protects You From

When a contractor holds full-scope TSSA certification, you’re not just getting a qualified installer—you’re getting full assurance that every part of the job is accountable, trackable, and code-compliant.

With PML, TSSA coverage includes:

  • Fabrication and installation of boilers, pressure piping, and vessels
  • Shop and field work under the same quality system
  • Documentation that’s audit-ready, from materials to inspection reports

This isn’t just about passing inspections. It’s about protecting your investment and reducing project risk before it starts.

PML’s Audit-Ready Model: From Shop to Site

Every part we fabricate, and every system we install, follows the same standard—whether it’s in our shop or on your site. Our teams are trained, our processes are documented, and our records are always ready for review.

Here’s how we stay prepared:

  • Standardized inspection and test plans for every certified project
  • Clear traceability of materials, welders, and procedures
  • Ongoing internal audits to ensure continuous compliance

This model gives clients peace of mind—and provides proof if issues ever arise down the road.

Certification Is a Commitment, Not a Shortcut

TSSA Certification isn’t a logo on a bid—it’s a signal of how seriously a contractor takes your project. At PML, we invest in full-scope compliance because we believe that safety, transparency, and quality should never be optional.
