"We contacted Indiana Foundation for a free inspection of our attached garage that we're turning into a bedroom for our handicapped son. We had several places that leaked where the wall meets the floor. A Mr John Hill did the inspection and then answered all our questions to our satisfaction. He was quite the professional but did not pressure us in any way, like most salesmen do. We decided to go ahead and schedule to get the waterproofing done. The cost was reasonable and it made sense to get it done now rather than wait for more damage to occur, making it more expensive. We look forward to meeting the crew. John Hill came as an inspector and left as a friend. Indiana Foundation is lucky to have him on their team."

"I know of no other contractor who has total customer satisfaction as his top priority like Mr. Flanagan does. He is absolutely the best.
My basement sustained ankle-deep water as the result of an outdoor basement stairwell drain that violently backed up because its circa-1951 drain line led to the street storm sewer (by design). That sewer was overcome with water during a storm in the summer of 2010 that featured a tornado in my western-suburbs area. Soon after pumping the water out of my basement with a mobile pump, the mess prompted me to (once again*) call Mr. Flanagan (*His crawlspace crew had done a beautiful job finishing my dirt-floor crawlspace with a concrete floor and wall insulation a couple of years earlier).
After the basement waterproofing project described in this review was complete, however, I was disappointed with the workmanship: The concrete work looked less-than-professional (out-of-flush with sump flange and the stairwell drain, plus way too many swirl marks and splattering) in the stairwell and basement's appearance areas. In short, it just didn't look like his business's flawless concrete job that was done in my crawlspace just years earlier.
Mr. Flanagan agreed. With no questions asked, he immediately had a different crew come to my home, tear out all of the previously laid concrete and drain lines and replace it with the workmanship that he would expect his crews to use in their own homes. The re-do of the project at least had met my high expectations for its cosmetics. And, of course, I hoped it was a sufficient waterproofing solution for my basement.
Fast forward just a few short years. Affter having perhaps sustaining that 100-year event with the Chicago-area rain storm of April 17-18, 2012, while my neighbors are pumping water out of their basements, mine remains bone dry. Thank you Mr. Flanagan and Crawlspace / Basement Waterproofing Solutions for a job (design and installation) well done. Your basement waterproofing solution indeed deserves an A+.

"Basement Seepage Solutions was my fifth quote. I almost canceled because I was sick of getting quotes and all the big companies charge about the same $70-90 per foot of drain tiles. Matthew's company beat these quotes hands down. He charges $50 a foot plus $10 off a foot for Angies list members (a savings of $1000 for me.). This company beat the next lowest quote by $3,600 so this was a no brainer. Matthew's company did excellent work. They were on time and professional and communicated with me the entire time. Also, Matt is on site during the process and is not just a sales man who comes for a quote then sends out a crew. The job took two days mainly due to the Villages inspection schedule. But I think this is preferable over the big companies that want to do it all in one day but are in your house from 8-8. Highly recommend if you need any sort of basement work done"

"David gave me what I thought was a fair price for the work to be done. He asked for 1/2 up front. As a previous small business owner I did not feel this was unreasonable so I paid him 500.00. He estimated the work would take 3 to four days and I thought the same. After several no shows the "mason" showed up. The first clue was he came in a car. According to my wife he was here 2 hours and left, came back for another 2 hours the next day and left again. He said nothing to my wife about leaving or when he would be back. David called a day later to ask about coming out to look over the job and get the rest of the other 500.00. I said he isn't finished and he's only been here 4 hours. So then I looked up the prevailing wage in IL for a mason and found out it is 28.50 an hour. The next day the guy comes back for another 3 hours. David came to look at the work and I walked him around and showed him all of the places that had not been done. So the guy comes back again for about an hour. All told it was 8 hours work, nothing to write home about but it was agreed up front that I wasn't looking for an exposed brick look. I need it tuck pointed well enough so that I could drylock and paint the exposed brick. I will say this was done in the end. The worker left a mess that I and my wife had to clean up, I pointed this out to David as well. I told him I felt he was overly paid for the amount of work preformed and that was the end of it. It's really to bad. It's difficult to get contractors to do small jobs and I had plenty for him to do. I'm not unhappy, just would not hire again"

"Scott had to repair/reinforce/replace floor joists in the crawl space and replace a basement window, repair cracks in the basement foundation, and replace a rotting wood post with a steel one. This was a complex job requiring Scott and his workman two days. They did an excellent job and did more than the contract specified, including wrapping foil tape around loose connections in the furnace ducts, shoring up unsupported floor joists in areas other than the original work order, etc. Scott is hardworking, knowledgeable, friendly and honest. I would recommend his company to anyone needing foundation, basement, and floor joist repair."

"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

Basement Waterproofing FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.
