CAPABILITIES
Industrial mechanical services to keep your facility running at optimum capacity
Are you dealing with razor-thin profit margins that can disappear with an equipment shutdown? With decades-long experience in troubleshooting and maintenance, Lee Industrial Contracting's mechanical services experts specialize in the systems that keep your facility running efficiently. We can install and service everything from process piping to HVAC and compressed air systems.
Qualified, Certified, Fully Supplied
Inventory: When we say fully supplied, we don't mean wait while we run to the store for parts. We pull stock from our massive in-house inventory every day. So, when we show up on your site, we're fully equipped and ready to work.
Self-Performing: Will installing piping or duct systems require changes to your facility? With most contractors, that means hiring subs. No matter the complexity of your project, Lee Contracting's in-house capabilities can handle every aspect of your job.
Value Engineering: Ever looked at a job specification and wondered if it was overdesigned? For years now, we've seen 'cut and paste' specs cost more than the benefit they deliver. Because we make every detail justify itself, you get better operational and financial performance.
Everyday Safety: Our Foremen are confined-space, OSHA 30 and First-Aid/CPR Trained. We require all of our Pipefitters to be OSHA 10 trained upon hire and we empower every employee on every job with stop work authority that is reinforced by our full-time dedicated safety department.

Pipefitting
Like the arteries and veins of the human body, piping systems keep things flowing. For years, commercial and industrial customers have relied on the knowledge and experience of Lee's pipefitters for professional installation and maintenance of those systems like no one else. Adherence to safety and compliance standards guards against system failures, secondary damages and downtime. Our certified installers deliver faster turnaround and rapid emergency response.
As one of the few single-source industrial mechanical services contractors in the industry, Lee Contracting self-performs every aspect of large and small projects. With our combination of a fully-stocked parts and equipment inventory and certified installers, we keep your job moving forward.
