"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

"Terrence Spranger was my plumber. His quote was fair. He was on time to the job. He replaced my hot water tank and shut off valve. He suggested placing a tray under the tank that has a drain hose just in case the new tank eventually leaks then it won’t run all over my basement. He had the model and serial numbers added to my receipt for insurance purposes. He was very personable and put the customer first. He went beyond what was expected of him to do. Thank you"

"I had a slow drain, but the plumber said my drain was not a clog. The problem was a non-functioning stopper. He replaced the stopper. He did a good job, but I felt it was on the high end for the repair work. It cost me $365 just to replace it with a new stopper. The work was great, but the price I felt was on the very high end. I confirmed the average cost for this job online (Porch.com and A.I.) Attached is the stopper that was replaced with a new stopper."

"I would like to thank Mariano and crew from Chicago Basement Systems for the very efficient work they performed in my home crawl space. They replaced my failed sump pump and drain tile; installed a Sani-Dry Sedona dehumidifier; installed a backup battery; installed steel beams and piers; installed a waterproofing membrane on the crawl space floor; and encapsulated the entire crawl space. Now I don't smell odors seeping from my crawl space, and my house no longer shakes when cars drive over the city speed bump outside my house. Also, I can now use my clean dry crawl space for extra storage. Thank you Chicago Basement Systems for peace of mind knowing that this project has a lifetime transferrable warranty. I highly recommend Chicago Basement Systems for crawl space repairs!"

Foundation Drain Installation FAQs, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

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.

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.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.
