After 30 years together, my wife and I bought our pickup and I am now looking to supplement my income by putting my pickup truck to work for me. Whether moving appliances or delivering purchases, I've got the tool for the job.

"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+.

"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!!!!

"Patrick had some trouble getting here because he was at another job when he called to find out what was wrong and was needed. He had to call two times knowing that he would be later than he said. When he arrived he spent 2 hours including checking other areas to make sure he was able to complete unplugging my bathroom sink. Think he even got basement sink running right. He did a good job.
