"Our basement has a huge sloping rock in it-the foundation was built around it when the house was built in the 50's. Over the past 5-6 years, water has seeped in more and more at the top of the rock where it meets the ground right next to the foundation and rolled down the rock to the cellar floor, threatening to flow over to the finished side of the basement. First we put a new drainage system outside the house but that did not help. Five years ago we had another basement company come and they told us all we would need is a dehumidifier and that would dry up the water. We bought their big dehumidifier but nope, that did not make a dent in it, it has just gotten worse each year. I called CT Basement Systems late last fall and a very, very nice representative came, looked at the rock and the water flowing down it and was confident their system would take care of the problem. I have a friend that used them for water in her basement and she has raved about them and has never had a drop of water since her system was installed. I paid the deposit and the technicians came exactly when they said they would. They did a great job, were very professional and left the cellar area very clean in spite of all the dust that must have been generated by the jackhammering. I am very happy with the job they did. However, there has been one unexpected problem. Before the drain was put in, I had been buying absorbent socks, flood bags and all kinds of things to soak up the water. Now we just let the water course down the rock into the drain guard, which then funnels it to the sump. We discovered that some of the water drains down to our brick chimney, which abuts the big rock . Instead of continuing it's flow down the rock to the drain, some water is soaking into the gravel around the chimney and then coming out on the other side, where there is no drain guard, making puddles on the floor again. We think the rock needs a thin lip of cement to direct the flow down and away from the chimney area. So, I called the salesman. No call back. I emailed him. No reply. I called and left another message but nothing. I called the company and asked if they would give him a message to call me. No response. So, I can only surmise that they are completely uninterested in this, now that the job is done. I now have a mason coming to do the cement. It is too bad, because I was so impressed with the salesman when he came and also with the installers. I would recommend the product and the installation service beyond a shadow of a doubt. But the lack of customer service after the fact is a huge disappointment. I actually do not mind having our own mason come and do the job. If they had called me back, I would have told them that- I really just wanted to get their opinion on the problem. But they apparently just don't want to be bothered."

"Great experience with Jade Construction and would absolutely hire them again. I had a drainage issue in my backyard and it made it hard to get the equipment in without destroying my whole yard. Jason was patient even though I had to reschedule a meeting twice early on, and acted quickly when conditions were dry enough to do the job. He installed a drain system and leveled out the land and both have helped a ton. Professional, helpful, and did a great job."

"Elson and company did a great job replacing a garage apron and old patio block sidewalk. He was always prompt from the estimate to the final inspection. He kept in touch with me on his work schedule, even when he had to bump out the start date due to the weather. He kept to his word and quote. I'd hire him again without question."

Foundation Drain Installation FAQs, answered by experts

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

Yes, professionals ensure proper grading and drainage to prevent water pooling.

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.
