Mark and his crew from the initial phone call for a quote was professional from the start. As a Firefighter it's important to me to have honest and dedicated people in my home. I got quotes from others around town and Mark was only one willing to attempt the job I wanted done. I requested a window to be used that was not and has not been used in the area. Literally no one knew about this window to include window providers. Mark said no problem and they learned as they went and the finished product is perfection. To top it all off they were cheaper than other quotes. You can not go wrong with hiring this crew. Thanks for making my family safer.

Mark and his crew did a great job of fixing our water issue in the Corn Crib Stadium! It was an issue for a few years and other companies did not seem to know how to fix it but Mark did! I would highly recommend him and Certified Basement Systems.

Mark and his crew at Certified Basement Systems cured a water problem that we had at the Corn Crib Stadium for years. He came in and did an assessment and had a plan that was reasonable and more importantly fixed our water issues!

We had several other companies come in and either had no answers for our water issues or would give us quotes that were out of this world to fix. Certified came in and got the job done at a reasonable cost.

Thank you to Mark and Certified Basement Systems!

Mark did a fantastic job! I had 7 leaks from cracks in my poured foundation walls. He took the time to not only determine how to fix the leaks inside, but fixed the cause of the leaks on the outside. NO EXCAVATING NEEDED! Simple things like proper grading to get water to run away from the house and burying the downspouts and draining them further away from the property. Plus I had water coming in from where my concrete patio met the house....and he sealed that too! It's been a year since all the repairs were made and have gone through some really heavy rainstorms. No leaking from anything he fixed, I couldn't be happier. I have found a new leak in the meantime and already have Mark from Certified Basement Systems scheduled to take care of it.
