"In drilling holes in our laundry room floor they drilled two holes in a hot water pipe. The repair work and expense related to this was greater than the cost of their work. No verbal or written mention was ever made about identifying the location of water pipes. I assumed (mistakenly) that they were professional enough to either ask me to have this done or be able to do it themselves. Their response to my complaint was to send me a copy of my contract reminding me that they are not responsible for "cosmetic" damage and that complaints must be settled through arbitration. "

B-Dry System of Mid-State Illinois
B-Dry System of Mid-State Illinois
The B-Dry® System has been stopping basement water leakage for homeowners since 1958 – unlike the “others”, this system is not a band aid but a permanent solution. We at B-Dry of Mid State Illinois Waterproofing believe that waterproofing your basement is absolutely vital, and we feel so strongly about it, we built a business around it! Keeping your basement dry is of the utmost importance. Excessively moist, wet basements can cause all sorts of problems, aside from simply smelling funny Before you consider another company to solve your basement leakage problems, remember that structural waterproofing is a specialized industry that demands experience if you expect your waterproofing to last. Waterproofing discounters often use subcontractors. Controls over experience and workmanship are difficult to manage and maintain. We handle every aspect of your waterproofing solution.
"Both gentlemen were very friendly, nice and polite. One gentleman was a smoker, but he picked up all his butts before he left and did not smoke in either the truck, the house or near anyone. I found this remarkable and would like to be able to say thank you personally. The initial quote for the job was also very well done. The person that came out was professional, showed up on time, and explained all steps (including why the basement was leaking and how they would fix it). Over-all I would highly recommend B-Dry to anyone."
