LeDuc & Dexter’s commercial department covers a wide variety of projects and industries including tenant improvements for public facilities, offices and warehouses, and industrial manufacturing plants requiring special gas and compressed air piping.


No matter how big or small the job is, you can count on our experts to get it done correctly and as efficiently as possible. Over the years, we have done many projects for commercial remodels, ranging from replumbing entire buildings to just installing things like new sinks. With experience doing all of these jobs, we have gained valuable skills that help us tackle any project that comes at us.


Commercial plumbing systems are generally much more sophisticated than residential systems. Whether repairing, replacing, or expanding, our licensed and insured plumbers can assess, design, assemble, and install your new plumbing equipment to work perfectly with your existing plumbing system.
