"AFS took on our helical pier and sump pump installation on our new home and we were offered competitive pricing, efficient communication, and a timely/clean installation. Our sales rep was Ben who was always available and informed, Tanner installed our sump pump system and was equally impressive, and Peyton managed a crew installing our piers who left the jobsite as clean as they found it. I recommend AFS for all your helical pier and sump pump needs!"

"I called American Foundation and Waterproofing regarding a significant, but localized, leak in a basement foundation wall. Michael arrived on time for the inspection appointment and performed a thorough inspection. He identified the cause of the leak and suggested several fixes that I could try myself. If the suggestions do not work, I will definitely hire this company. I believe they are honest, professional, and know what they are doing."

"Donna and Jeff (owners) were hands on supervisors. They both patiently answered lots of questions and provided recommendations and resources out of their scope of business.  I felt confident that Jeff and Donna knew their business well and that my best interests were being well served.  I feel confident that they will respond quickly to any questions that I may have in the future regarding this project.  I would recommend them without any reservation.  I felt like I was fairly treated and charged a fair price for their services and the system installed.  Stated scheduled was maintained with proposed start and completion dates.

"Perfect! Charlie came immediately, hand dug down 4' to the tank, and pumped. Inlet was full of roots, which he cleared and told us how to avoid that problem in the future. Came back a few days later and installed riser on tank lid so that digging would not be necessary. have used several service companies in the past and there's none better. He returned and did 3 more for us as a preventive measure. If he's available, we won't use anyone else!"

"Called and made appt and plumber showed up on time, having called first.  He quickly determined the issue and fixed it and showed me how to fix it in the future if it happens again.  It did not need any parts or much labor so he charged me the minimum for coming and assessing the situation and then solving the problem.  He was very nice and professional.

Sump Pump Installation FAQs, answered by experts

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

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.

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.
