"We were pleased with the customer service, skill set and careful attention provided by Indiana Foundation during last week's waterproofing work on our basement. Josh Solomon and Noah Salisbury were diligent in their attention to our questions and concerns, going the extra mile to ensure a quality installation that met our needs. Our basement is already drier and we hope to build it out for a play/rec room soon."

"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"

"I walked into my basement on Saturday afternoon to discover a pool of water on the floor.  Looking at the walls I traced it back to right above the window that sits below my kitchen sink.  I popped the paneling off the top of the window box and immediately saw that the galvanized pipe leading from the sink drain to the stack had corroded and a hole had formed.  Frantic because it was 4pm on a Saturday and I knew I couldn't use my kitchen sink or dishwasher until I got this fixed (no easy task with two toddlers to keep up with), I jumped onto Angie's List looking for a plumber with Saturday hours and a good rating. 
I called McDonagh and was told they could have someone at my place in an hour.  Todd showed up at 5:30 and immediately got to work.  Patrick (the owner) showed up with his son Nolan shortly thereafter to take a look and get Todd some parts off of his truck.  We gave Nolan a piece of the pizza my kids were having for dinner as an apology for interrupting his Saturday too.  Patrick came back with a price estimate that seemed fair to me for emergency short-notice service on a Saturday night.  Todd replaced the entire section of pipe from the sink drain to the stack and was finished and out the door by 7:30, leaving us with a fully functional kitchen again. 
Huge thanks to Patrick and Todd (and Nolan) who really saved the day for us.  These guys are absolute professionals and really saved us from some major inconvenience.  Would absolutely recommend and use them 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."

Basement Waterproofing FAQs, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.
