  Certified Basement Systems (CBS) installed a tray system along the inside parameter of my lower level. My water problems are now a thing of the past! This was the second house I've owned in Bloomington that CBS has solved my water intrusion issues with their systems, which is why I was compelled to write a review. Additionally, Ricky was an above-and-beyond style foreman who made sure it was not only done right but also put back the way it was pre-construction. If you want to say goodbye to your water issues, give them a call to see what solution they have for you!

  Mark and his crew did an exceptional job installing a dewatering system in part of our basement. This is at least the third time they have helped us with varying water problems in our lower level. Each job was a different problem, calling for a different resolution. None of them were simple installations. They required innovative, complicated techniques that Mark and his crew were able to implement to solve the problem on the first attempt. They were messy, involved processes. Each was executed with minimal mess and a thorough cleanup after. They even found time to add an assist that wasn’t planned at the outset. We can’t compliment them enough or recommend them highly enough to anyone who has either a run-of-the mill job or a job that requires thinking outside the box.

  Mark and his crew did a great job. Professional, on time and courteous. They even dug up and replanted our hostas after they were done. 5 stars.

  I have used Mark / Certified for 3 different jobs: adding an egress window in our basement; installing a sub-slab dewatering system; and then expanding the system years later. The crew does fast, excellent, clean work that is reasonably priced and guaranteed to work. Today, Mark came out to solve a problem that was not even his to solve--helping my carpet installer choose the correct adhesive to hold down carpet tack strip (which needs to be adhered rather than screwed to avoid puncturing the system). He ended up doing the job himself--for free (I bought him lunch). He has helped us troubleshoot before each project, making sure that we were choosing the correct solution for the issues we were trying to resolve. I can't recommend Mark and Certified any more highly! It's no fun to need dewatering work, but this is the only company in the area worth trusting.

  Would highly recommend the work they did and especially the service they provided! They were very kind and willing to walk us through the processes and explain what all was happening. They helped address any issues that came up once the job started and showed a commitment to making sure our basement no longer had water in it.
