"We recently had a team work on our home to fix a variety of foundation problems. In short, good communication and friendly customer service. Our sales rep Michael Freddolino was great. He was quick to respond to my first call and followed up without pestering when my husband and I dropped the ball and explained everything in a way we could understand it. Austin, Johnathan, Chris and Isaiah were the crew who worked at the house and were the nicest and most respectful group of workers. They were careful with our home, inside and out and cleaned up any mess that was made. They communicated very well with us to let us know how the progress was going and other items they ran into so they could be resolved right away. And if you can believe it, we ended up spending less than was originally estimated! I would definitely recommend them."

"Had them replace a drain pipe in my foundation. They were timely and efficient. Price was very good as I have been through this nightmare before. Really appreciated Keith and Nico! When Keith arrived, I instantly knew I had the right guy advising me on this. Nico did a great job doing the job. Thank you both."

"I hired Canyon Dirt Works to redo my driveway with gravel. I needed a French drain in front of my garage to prevent runoff. Chris and his crew did an excellent job! Even redoing a parking area in front of my house. Work was beyond my expectations."

"We have been living with a sunken patio and a walkway that slopes the wrong way for years and we finally decided to do something about it. After a lengthy Google, Yelp, BBB and other site searches we solicited bids from four concrete contractors. We selected Legacy. From the initial estimate through final inspection, The owner, Robert, and the crew were fantastic. Our situation was a difficult one, and no other contractor could develop and execute a creative solution that addressed all of our many issues. Jacob and the work crew were great to work with, kept us informed throughout, and really produced a wonderful result. Legacy was not the lowest bid, but was by far the best design to do the job. We can’t recommend this family business highly enough."

Foundation Drain Installation FAQs, answered by experts

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 drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

DIY is possible for basic setups. Professional installation ensures proper drainage and reliability.

If you hire a professional, installing a new sewage ejector pump costs $850 to $3,500, or an average of $2,300. Otherwise, if you handle the installation yourself, you can expect to pay $500 to $1,000 for the sewage ejector pump, permits, and other supplies required for this DIY project.

No, you can’t drain your sump pump into your home’s sewer system. In fact, it’s against the law in many places because dumping extra water into a municipal water system can disrupt or overwhelm the treatment process. And for similar reasons, you shouldn’t discharge a sump pump into your septic system, either.
