"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."

"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

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Fortunately, there are ways to create drainage when adding a bathroom to a sunken garage. Plumbers will recommend using an upflush system that discharges into a pump from the back of the toilet.

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.

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.
