"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"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."

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

"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.

Sump Pump Installation questions, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

A water pressure booster doesn't require special maintenance. Like any house system, inspections should be a regular part of your annual schedule. Check for leaks, faulty valves, pressure loss, and mineral build-up. Pressure loss could be a result of mineral build-up, and you can descale the system with a vinegar and water solution.

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.
