"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."

Basement Waterproofing questions, answered by experts

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
