"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."

"Project: Repair sagging floor joists, installed footings, gravel and smart jacks. They were done in a few hours. They stared on time, kept in contact with us by email, phone and text. Will use them again if we have any other basement needs. Review by Leo C. in Dallas, Pa."

"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

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.

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.

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.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

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.
