"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"

"Since this is our first home we wanted it to be Perfect!. David promised to have the complete painting done before we moved in. He came on saturday morning and was working till sunday afternoon to have the house ready for us.Such dedication is difficult to find. He also helped us pick colors and the place has turned out to be better than we could have ever imagined. We have new flooring and he took care that there is not a drop of paint on it. All in all very professional and very good at what he does. We are already planning on few more projects with them!!!!

"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

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

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.
