"We needed new gutters on our home and decided to hire MidAmerica Basement Systems. From start to finish the process was incredibly smooth and communication was great. Would hire them again any day!"

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"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"

"Our house had a water damage that ruined much of the drywall and floor on the first floor and the basement. For such a big repair job, I carefully looked up the reviews and recommendations from Angie's list and talked to 3 contractors that have the highest ratings. AOM was one of the three. David, the owner of AOM, quickly came to our house, assessed the damage, explained to me what need to be done, showed great empathy to our loss and current situation (having to stay in hotel waiting to go back to our house), and put a very competitive bid (about 2/3 the bid of another contractor). We picked them and signed the contract. AOM uses Trello, a cloud-based project tracking system that software companies often use, to effectively and promptly communicate task description and updates to all workers and house owners. AOM workers are professional, hard working, and friendly. For such a big project, expectedly there were some hiccups and AOM had to juggle ours with their other on-going projects. David kindly explained to me various aspects of the repair work and promptly fixed any faults that we identified. I became to completely trust David's professional skill and that he would treat our house like his. Several nights and weekends David came to work late so that we could move back to normal life as soon as possible. In the end, we are very happy with our remodeled house. I sincerely recommend David and AOM for any house remodeling and restoration job."

"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.

"During the quote phase I met with several contractors. Out of everyone the price was a bit higher but the character and quality was worth the slightly higher price. The project took longer to begin than expected but that was due to weather which I was fine with. Once work began it took only a few working days to complete the job.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
From average costs to expert advice, get all the answers you need to get your job done.
