In 2008, Landry Mechanical Inc Plumbing HVAC & Electric began serving residents throughout Worcester and Middlesex County. We started out just serving 20 systems a year and working on systems that our competitors ignored, such as wood systems or alternative energy systems. In putting our customers first, our reputation for quality work grew, as did our business.

"Very professional,on time and kept me informed.Did a great job, looks great!"
