"In response to my initial email inquiry, Eric, the owner, came to the house and we discussed all of the issues and how they would deal with them. He took measurements and pictures and was very professional, polite and encouraging. Within a few days he emailed me a very precise and detailed proposal outlining all three jobs and the estimated cost. I immediately accepted. Adam came to the house and took some more measurements and pictures and said the work would begin the following week and take three days. The required permits were taken care of right away. As scheduled, Paul (the onsite foreman), Lloyd and TJ showed up and began to work. Braces were installed against the basement wall after the cracks were repaired. On the exterior a French drain was put in along the side of the house extending to the ditch out front. The old walkout was excavated and a new permentry door was installed. The work went as planned with no problems and was finished in three days. All debris was taken care of and they cleaned up when they were through. All of my questions and concerns were answered. Adam followed up the day after the work was completed to see if I was satisfied and to answer any additional questions. I also must give kudos to Cynthia, the office manager, who made the paperwork and payment process smooth and effortless. The quality of the work and the quality of the employees is just exceptional.

Foundation Drain Installation FAQs, answered by experts

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.

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.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.
