"Masle and his team did an excellent job, going above and beyond to repair the entire system, replacing all of the rotten sills, beams and floor joists in a 120 year old mill house. And since he was also able to do the encapsulation and drainage system installation, I was able to work with one company to get everything completed. His pricing was very good, and added additional piers when he found it necessary without charging extra. I would highly recommend Uneven Floor Solutions for any foundation issues you might have."

"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!"

"Johnny and his crew showed up at 7AM the morning they said they would. Stayed with my 10-yard pad pour with French drain for 2 more days. Very pleasant, professional and honest. Worth more than the $9,000 price. Totally IMPRESSED."

Foundation Drain Installation FAQs, answered by experts

Installation typically takes 3-7 days, depending on the system and site conditions.

A sump pump will drain a flooded basement if it has a horsepower strong enough to remove the water faster than it is entering the room. If you have the wrong type or size of sump pump installed–or if your sump pump has failed–you may need to take additional steps to stop the flow of water or remove it manually.

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

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

The cost to install landscape drainage varies widely based on the scope of the project and the severity of the drainage issues. Typically, this project’s cost falls somewhere between $2,000 and $7,000 overall. Small-scale projects or simple fixes may start at the lower end, while more extensive and complex solutions could reach the higher end of the range. To get an accurate estimate, you should obtain quotes from multiple companies, as they will assess your specific needs and provide a customized cost estimate based on the work required.
