"They were great to work with and came in with a competitive price. They were clean and efficient. Had 125 feet of French drains installed through our basement with 2 sump pumps done in one day. Came back a few days later to complete what was needed outside the house."

"Hi, I am an old customer of Select Basement for many years. This is my incredibly happy and satisfied review on the service call by Kenny M. First the backstory. The alarm went off on my battery backup on Wednesday early evening I called Select several times and no one got back to me. I just wanted to know if this was a serious problem. Considering all the rain we were having that week. This was unusual for Select not to return my call in a timely manner from the great service I had received from Select Basement for many years. I explained to the customer service representatives who took my calls who were very professional and tried to help but to no avail no one called me to answer my question. I received a called back Friday morning to set up an appointment for Monday to look at the alarm on the battery backup to the sump pump. I inquired if our annual maintenance check could be performed at the same time and was told yes. Monday morning Kenny called to say “He was on his way”. My appointment was at 8, he arrived 7:45. This was great because I had a 9:00 virtual business meeting. I explained my frustration with Select Basement and merging with Groundworks. Kenny took the time to explain the system changes and how things work now with Groundworks. Kenny proceeded to look at the battery and said it is working properly now. He asked how long we have had it. I said several years he recommend changing the battery, which he did. Kenny also performed the maintenance of flushing the French drain system to make sure that is still working fine. He took several pictures along the way to validate what he was doing. He addressed the dehumidifier that we have, he adjusted it so it would drain into the nearest little french drain hole. Kenny did a great job. He was careful to address all the issues that he thought needed to be addressed. Kenny was very professional and respectful technician leaving no mess behind. Our water has a lot of iron ore, Kenny cleaned the ore around the pump and also offered a recommendation on how to reduce the ore around the pump. He also explained the difference in the service pricing for the warranty offered. I appreciated Kenny taking the time to explain everything that Groundworks now offers to their customers. I know Select Basement and Groundworks merged only a few months back. However, the most important thing is customer service. If I called on Wednesday night thinking I am having an emergency, I should not have to wait for my call to be returned on Friday morning. I text Jason from Select Basement late that evening since no one got back to me right away . Jason responded right away and put my fears to rest and suggested a few options for the alarm shut off that did not work. He said he would pass the issue to the one of the managers. There has to be better response to customer when several calls are made with not even a touch point call back. Thank God by basement was not flooded. Select would have lost a customer."

"Erik and Chris were absolutely amazing. Erik’s communication is impeccable—he explained everything clearly, from cost to timing, and made the whole process stress-free. My gas steam boiler failed during one of the coldest winters in decades, and they handled the removal and installation quickly and professionally. The job was done in just a few hours. I couldn’t be happier and highly recommend them.!"

"Very prompt service. They came right on time. Explained consequences of clearing drain. They did everything to keep the bathtub and floor clean. I would hire again for plumbing needs! Price was great and they will come back if I experience another clog within the year."

Sump Pump Installation FAQs, answered by experts

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.

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 drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

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.
