Basement Finishing & Remodeling in Ottawa, IL

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Ottawa contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

W Madison in Ottawa
Looking to purchase a home. It has everything we like, but the basement walls have significant bowing. Looks like a perfect candidate for foundation wall anchors. Simple rectangular basement ~28x52'. Both long walls are in need of correction. Before I go through with the sale, I would like to get an estimate to correct the basement walls. And I would like to know if the house is generally structurally sound. All floors are flat and level, not creaking, or sinking. It feels really solid on the living floors, but the basement has a lot of water seepage due to the significant bowing walls. The house is not occupied, is for sale, and has our offer pending on it. The seller said he is selling the house "as is" - and after the inspection, I am a little scared now. I just want to know what the repair cost will be before we finalize the sale. Thank you. Please email me - I have very poor cell reception where I work.
