"My interaction with Jordan Gast (and later with the owner Jim Briley) was first rate. Jordan was very knowledgeable, thorough and helpful in designing a solution. He also allowed me to pester him at several later times with questions and concerns. The work done (with the company owner actually participating in the project) was absolutely first rate. They left the site having created a beautiful addition to the yard that I believe will provide the drainage relief that was needed. The owner actually spent several hours digging under a buried rock to ensure optimal drain pipe placement; it would have been very easy to just run the pipe over the top of the rock but he insisted on getting it right. I believe that Jordan and Jim are both honest and competent in their work. I would not recommend anyone but them for work of this nature. I stated NA on the pricing question because I got no other quotes with which to compare because I was completely satisfied about using this company after our first meeting. We are 100% satisfied with the results."

"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"Nick at Ethical Plumbing did a great job fixing our drain issues! We already had several plumbers out to our home to try to fix it but were unsuccessful. Nick fixed it AND saved us money. We will always use Ethical Plumbing from now on. Highly recommend!"

"From start to finish working with this company was a wonderful experience! DJ was our point of contact and he is very professional and knowledgeable. He ensured we were adhering to city coding as well. The team worked efficiently and our patio looks better than we could have imagined! They noted holes in our underground drain spout and purchased us a new one during the patio install! They went above and beyond and we could not be happier with the results! Highly recommend this company and all employees."

"We would highly recommend Sampson Concrete. Gideon made multiple trips to our home to help us determine the best design for our projects. The team arrived on time and were very professional. They took additional care to repair a French drain that had collapsed before pouring our patio. We had multiple projects today and are exceptionally happy with all of them. We will be hiring them again."

Foundation Drain Installation FAQs, answered by experts

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Costs range from $2,000 to $7,000, depending on system type and excavation requirements.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

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.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
