"The leak was worse than what we thought. Originally we were told by our general contractor who did kitchen remodeling 9months ago and we forgot about it. And 9 months later, the smell got really bad and asked Deep to repair. He was very flexible on schedule when he comes down to estimate and actual work. He came after my husband and I got home around 6pm and did estimate and did the repair and installation on Saturday of same week. The only thing I can mention about is his estimate was very abstract. He doesn’t even give me written estimate. He just texted me the total cost of repair from $450 and up and tank installation $1300 including tank. This is aster I asked him to send something in writing. But he keeps his word. After all the work is done, he sends me digital invoice. No increase except the leak work. This is understandable since nobody knew how bad our leaks was. He canceled afternoon appointment since our repair work took longer than he thought. So we paid him some extra as tips. We were glad we did after the week, when we went under the house to clean up the leaks and found out 6’x6’ pool of rotten sewerage water cooking on the vapor barrier in he crawl space and made the nest for bunch of tiny flies...yuk!!!! We wondered how he worked around the grossest sewerage water..."

"Our former heat pump had been a problem from the day it was installed by a "Discount" installer. G&S correctly diagnosed the many problems and gave us the option of either fixing or simply replacing the unit, which we did. They communicated extremely well and ensured we understood all our options. There was never any pressure to do this or do that. The installation crew was very professional and completed a customized installation (had to match up to our existing propane furnace) that was very neat in appearance (in stark contrast to the former installation that looked like it was a practice job for a Jr. High shop class). They took the time to ensure that we fully understood how to operate the system. They even sent out a "follow up inspector" a few days after the installation was complete to very that all the details of the project had been well handled. Given the level and quality of the service and equipment, the price was competitive and fair to both parties. They are Highly Recommended!

"They did a excellent job. I had 3 plumbing companies out to try and figure out why I had no hot water in my home but premier did. The first company said I had a faulty water heater. Heater was only 7 years old. They replaced it and told me to wait 2 hours and still no hot water. They came back out and said it was a defective unit. They replaced it and still same issue. I hired another company and they couldnt figure it out. Here comes the professionals. Premier checked everything and found I had a faulty shower cartridge. The cold was mixing into the hot. Easy fix and we had hot water again. Thanks again premier plumbing. Ask for the tech Chriss. He is awesome."
