"Shawn and his entire team were friendly, polite and took great care to keep our home clean and with little inconvenience during the project of drain tiling and installing a sump pump in our basement. They also fixed a crack in the wall that was discovered after the estimate was created."

"This is the second time we have hired Groundworks (formerly Bakers Waterproofing) to perform work at our house. The first project was in 2017 when we had the waterproofing system installed. We called Groundworks a few weeks ago to get an estimate on lifting our front sidewalk and stairs that have sunk a lot over the past year. The steps had sunk to the point that the railings were not connected to the house, making it very unsafe for anyone coming into the front of our home. Aaron Lenker & Corbin Gillichbover were very professional and knowledgeable when they arrived to assess our sidewalk and steps to lift them. They left our sidewalk and the surrounding area better than when they arrived. Our steps and sidewalk are now level, and the railings are securely attached to the house again. We are thrilled! I would highly recommend Groundworks if you need a basement waterproofing system or any concrete lifted."

"We had Flood Crew out to help when our hot water heater broke. Bill and his crew were great! From the water remediation to installing a whole new floor in the basement, the crew took care of every step. These are some of the hardest working guys I’ve ever seen! And they don’t play around, they get the job done. I recommend them to anyone needing this type of work done. Thanks a million, Bill & crew! ???"

"They were professional and timely, but they were also my highest bid. I hired them for their guarantees on the work and their sales rep was very good in that I never felt pushed, he showed me exactly what they would be doing and spoke to me as an intelligent human, not condescending. The guys doing the installation were courteous and workers, they didn't dawdle about or goof off, and it was hard work ripping out my basement floor and digging through all the underlying rock to make their trench. And they did it all in 3 and half days."

"The work was messy but The crew was very hard working. The jackhammer hit a pipe under our sink. They came back to fix that. While the amount of water was drastically reduced in our basement, I will never feel secure enough to finish it. They have returned 4-5 times to troubleshoot the problem because their service has a lifetime guarantee. The last time they came (2 years after original job) they added another sump pump and redug one of the ditches. It seems to have helped but I still see a very small amount of water seeping through a few cracks in the floor. With two small kids in the house, it's exhausting to keep having service people in and out of your house. I'm not happy it took so many visits, but I think overall that they were fairly quick in responding to my calls and getting out to our house."

"Great job, replaced old draining system from previous owner and placed a French Drain around the basement alleviating my water issues. Only issue I had is that they removed a 1 yr old Sump Pump and never gave it back after my request numerous times. That's been at least 3 months ago. Good group of guys!"

Sump Pump Installation FAQs, answered by experts

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

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.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

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.
