"Gage has been excellent to work with. We will hire him any time we need something in the future. The work site is always clean, the new install always looks tidy. He has installed a water filter, fixed several leaks in old plumbing, replaced hose bibs, worked on our booster and expansion tank, replaced fixtures. It's always great work."

"I got a call from Mike right after placing the request. We set up a time to come out and fix the clog in my tub and he was early. Within 45 minutes he had the clogged drain fixed working properly and gave some professional advice on the drain system. I would highly recommend using them for all plumbing needs."

"The owner visited and provided an estimate in a timely manner and was very personable. The estimate was very reasonable and the work began on time. All workers were professional but it wasn't made clear most of the time, what time they could be expected to arrive on subsequent days after the start."

"Mike and his team did a solid job for us. The previous owners had punted on installing
the correct solution and lied about water entering the home. When we found ¼ inch of water in our back
room basement we called GMBS out and they were there within hours to do an
estimate.
This was one of the rainiest summers in recent memory and
GMBS had a ton of business so we had to wait, but it was worth the wait. They finished the job in under 3 days and the
work looks great.
They installed a brand new sump pump, the old one the previous owners had
installed was done poorly, was inefficient to the task and sounded like a jet
engine. They installed a sub floor
perimeter drainage system and vapor sealed our walls.
They were quick, professional, courteous and were easy to
work with. We paid up front and part of
the job was over estimated and they got a refund to us when we needed it.
I have more work I need done in the future and I plan on
using Mike and his team.

"The work was done neatly. It looks good. However, the plumber told me that condensation of this type can be acidic and we would need an alkaline filter. Because of circumstances we were in a hurry and had no time to discuss or verify this information. A previous contractor whom I called to ask about a new furnace told me he would add a simple pump and hose to the cost of the furnace for $60. The installed filter looks very sophisticated and I believe added a lot to the cost of the job. The invoice was not itemized. I neither asked for nor received a cost estimate of the work to be done. The work may be fairly priced and necessary. It seems excessive, but I did not investigate. The fault, if there is any, is partly mine."
