"We highly recommend US Waterproofing. Unfortunately, after repeated issues (we’ve had water getting through a basement door, water backing up from drain/sewer pipe, foundation cracks – all which were addressed) we now have had issues with hydrostatic water pressure delivering a great deal of water to our finished basement. Only one solution – drain tiles and sump pump installation. US Waterproofing was outstanding, every step of the way. They communicated clearly what was needed, and much to our surprise, what was not. They did not ever try to sell us anything that was not needed – only what was – installation of drain tile, window well drains, sump pump, and all work related. All of the crews involved were outstanding – in particular, the crews installing the drain tile and sump pump. The supervisor clearly and concisely explained every step – and when issues arose, they were dealt with promptly. The teams removing drywall and reinstalling also did very good work, and were very responsive. Everything was done correctly, and on schedule The work is now complete – and the basement is back to normal. I commend USW on all facets – they explained everything, did not try to oversell anything, and were responsive to issues as they arose. All the way around – sales, customer support, install teams – outstanding. If you have an issue with water in your home, please consider US Waterproofing."

"Out of the three basement waterproofing experts we called to offer solutions after getting a lot of water in the basement of our 1925 home, Joe at The Real Seal was the only one who seemed to take serious time in investigating the cause. He even came back a second time after we got more water in another spot to see what could be causing it and what a cost-effective solution might be. On top of that, the price was right! We never ever felt pressured into committing to the work, and they seemed confident in their skills to get the job done. Our partial interior drain tile job was finished in two days. While we can't yet vouch for the drain tile's efficacy since we haven't gotten a large spring rain yet and we're still in the process of refinishing our basement after it was demoed for this work, we expect we'll have a dry basement!"

"I worked with Austin Werner at Real Seal to get some basement sump pump work done. He came out initially and gave me a quote and different options for my basement sump pump. He was very knowledgeable and gave pros and cons of different options. The quote was priced very fairly. They were able to get us on the schedule quickly. On the day off, the Real Seal technician called me the morning to let me know what time they would be here. The job was done very professionally and they answered all my questions. They cleaned up after the install. Highly recommended."

"I needed the sill plate and rim joist replaced, sister in the joist in the front of our house. They had many jobs going on so they brought in a crew Anthony, Jerry and Jose from New Jersey so the could get mine done. Anthony let me know what they were doing as things progressed. He asked me if I had questions as he worked. Everyone in the crew where so considerate. The laid down tarps to walk on so as not to damage my floors and they cleaned up everything and the end of the day. I would recommend Chicago Basement Solutions to anyone who needs work done in their crawl of basement."

"We called Patrick to fix a sewer smell in our basement. After digging out a section of the floor, he found a pipe installed by the previous owner that had never been correctly attached to the sewer main. He and his crew worked on a Friday and Saturday to fix the issue. They jackhammered out the floor, dug up the old pipe and replaced it. Patrick was very attentive and showed me all the steps he was taking, carefully explaining everything that needed to be done. Cleaned up afterward and finished the job without issue. Highly recommended."

Basement Waterproofing FAQs, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.
