"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+.

"I was concerned that I had mold on my basement walls.  Rich assured me that it was not mold on my basement walls.  However, he did find some mold on the wood on the ceiling.  But he told me that I could wash that off myself and he told me how to do it.  I have medical issues  and my husband is 70 years old.  We are going to try to do this ourselves.  But if we are physically unable to do it, we will most certainly use Rich and his team.  Rich seemed very knowledgeable and was very friendly.  He did not charge me for the assessment even though he took time out of his schedule to come to my house and assess my basement.

"Three letters signal how it went: C C and H Competent in many different parts of home improvement and repair. Careful in all their work. It is not rushed, it is done meticulously. Honest. They will never tell you you need something done just so they can get work. If anything needs to be done, they show you pictures of it and explain it in detail, and then they give detailed items in billing."

Subcontractors FAQs, answered by experts

You have three options in terms of professionals who can draw up blueprints: a draftsperson, an architect, or a structural engineer. A draftsperson can sometimes draw up plans for new construction, but they more often work from approved plans for alterations or to provide 3D drawings. Architects are usually the best option for standard residential construction projects. Structural engineers might be necessary for custom home builds or for alterations that could affect your home’s structural integrity. Draftsmen cost the least of the three, followed by architects and then structural engineers.

Costs depend on project complexity, software requirements, and the draftsperson’s experience.

Regular meetings, reviewing drafts, and providing input on materials help align the project with your vision.

Yes, pros can offer guidance to achieve desired aesthetics and match existing decor.

Yes, new home construction will always require building permits, no matter where you live. In most cases, you’ll need a general construction permit, along with plumbing and electrical permits for the utility lines in your home. Depending on where you live, you’ll likely find that you also need permits for things like connection to a sewage system or installing exterior components, like decks, driveways, patios, and curb cutouts. Leave navigating the permits required for new home construction to a professional to ensure your home is built legally and safely.
