Would not recommend. Our builder, Antares used them for new home builds.
The work was very poor quality from the start. Appeared rushed and/or unknowledgeable. They had to come back three times for repairs. First to fish loose pvc pipe out of the drain amongst other things. Brand new home- toilets backed up, shower wouldn't drain, etc. The guy who returned the first time, argued about fixing an upward (supposed to be downward) sloped drain hose. PVR present without expansion tanks. First guy came back and put on one expansion tank (for two hot water tanks on an non-connected system) that was not new and only one tank.
Had the city come out and inspect and confirm that it was supposed to be two expansion tanks and they needed to be new (city inspector confirmed expansion tank that was placed looked used.)
I Scheduled appointment during the 10-12 window. I never received a pre-appointment confirmation call so, I called to make sure it was still on. I was told the service crew could arrive anytime 9-10. I said, I have another appointment at 9 and wouldn't be home til 10 as my appointment time with GLG was 10-12 window. The office receptionist and I confirmed 10-12 window and she said it was taken care of. The plumber showed up at 9 am the next morning anyway. On the phone with him, I tried to explain my 10-12 appointment window and the fact I called to confirm the day prior. He was very very rude and unprofessional in conversation and hung up on me! He also noted that I would not receive service today and was very unapologetic. He was also very aggressive in both conversation and in person. I reviewed my video camera footage from my home and saw him throw his tool box and tools into the back of his truck. I mean very aggressively (imagine a long, appeared to be thick tool box. It appeared it wouldn't close or cooperate- he picked it up hastily and threw it so hard that It rotated at least 360 degrees and flung to the inside of his truck bed- (thank God it was the tool box and not me or my home.) I also had asked him his name during the call and he refused to tell me. It's a red flag when an employee refuses to identify themselves and their legitimacy.
I called the company. Office worker sounded surprised. I refuse to have the unprofessional, aggressive man back. They scheduled me with owner's brother and a lady for another day. They were professional, timely, and nice. They explained everything to me and were quick with repairs.
Per my request, I was told that the owner would call me so that I could talk about my experience and he never did. It's been a week at least.
For unprofessionalism and poor workmanship on multiple occasions, I give this company a one star.
