"Excellent service. I had a sump pump system put in 10 years ago by Rescon. Never had any problems with it, worked great. This weekend with all the rain the pump stopped working. I called there emergency line and a service technician called me back in less than an hour. They were at my house in less the 2 hours fixing my pump. They did charge me an emergency dispatch fee for the service call but I guess that s expected on a weekend. Overall it was excellent service and I am very happy I chose this company."

"This company did not do my work. I incorrectly reviewed them as their name was similar to the contractor who did do the work. Sorry for confusion."

"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."

"We were concerned with a couple of issues and they put our minds at ease. They were professional and efficient; George and Joe cleaned up after themselves, were very carefully to always use a drop cloth, and kept us in the loop on the installation. If we had one area we wished that Lake Sunapee Heating would improve it would be in the area of customer communication. However, we are more than satisfied with their work and would recommend this business.
Overall assessment: quality workmanship at a reasonable price.

"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.

"Excellent! He installed the railing on very short notice. He is very difficult to contact but if you get him on site, he will do a good job. He is inexpensive and worth the effort. I will use this provider again.
