Basement Finishing & Remodeling in Williamsburg, IA

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 Williamsburg 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.

Crack Injection Helps Prevent Basement Foundation from Leaking for Home in Williamsburg, IA

Trent was out doing yard work when he noticed a large foundation crack by his basement window. He was very concerned that it would leak causing damage to his finished basement. Members of MidAmerica Basement Systems proactively installed a Polyurethane Crack Injection to seal the crack. The Polyurethane Sealant is a high-viscosity polyurethane polymer that gets deep into the cracks, forms to the crack, and provides a durable, flexible seal, preventing water from entering the crack and into the basement. Trent can now rest easy, knowing that his basement will not be ruined from water entering the foundation crack.
