"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."

"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.

Sump Pump Installation questions, answered by experts

If you’re wondering if your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

You should be fine. Most high-grade grinder pumps have a 24-hour holding capacity within the tank. You can continue to use the facilities so long as the power outage does not stretch into days. In a worst-case scenario, attach a generator to the grinder pump, providing it has sufficient electric capacity.

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.
