The installation crew was courteous, talkative and fast. Great pains were taken to keep the work area clean. Robbie Stoutenberg is obviously respected. I could see that he is taking care to teach his crew craftsmanship and customer relation. They are a very well organized trio.

Basement Finishing & Remodeling in Seneca, 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 Seneca 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.

Job Stories From Seneca, IL

ThermalDry Floors in Seneca, IL

Homeowner Ann and Gary contacted MidAmerica Basement Systems to learn more about the basement flooring options that they offer. The ThermalDry Flooring is made of all inorganic materials that will not mold or warp. The floors can be removed and replaced at any time. They fit together like a giant puzzle and can be pulled and easily replaced.

Flooding Basement Drain is Properly Addressed in Seneca, IL

During large rainfalls, Adam would have issues with water backing up through his basement drain causing large messes. He thought that contacting a plumber to fix the drain would solve his problem, but it continued to happen. When MidAmerica Basement Systems assessed his issue and they concluded that it was water seeping into his basement, and due to the drain being the easiest access to surfacing the floor, it was causing the drain to flood. A WaterGuard drainage system was installed along the perimeter of the basement to collect the seeping water, preventing it from reaching the drain, and redirecting it to a TripleSafe sump pump. Now instead of water seeping up through the floor drain during heavy rains, no water is noticeable because it is properly discharged from the home.
