On behalf of W.E. O’Neil, working with J & G System has been a successful and rewarding experience based on the GF III Project. They have gone beyond the call of duty with no interruptions regarding field operations and working alone side other trades. They are punctual and committed to provide the service which they were hired to perform. I would recommend J & G Service on any projects or client relations as a reference for them.

J&G Systems has completed six build-to-rent projects for us, and we can say, without hesitation, that they have been the best plumbing subcontractor we’ve worked with. Their team is consistent, reliable, professional, and takes true ownership of their work. Quality of work, effective communication, and responsiveness set them apart in an industry where those qualities are hard to find.
