Basement Finishing Case Studies: New Basement Gets Flooded and Survives

Monday, July 9th, 2018 by Christine Natale


A homeowner in Seneca Falls called Marshall Exteriors to finish his basement space to create a relaxing yet fun space for family and friends. The Marshall Exteriors team remodeled the entire basement giving the family a theater space with stage seating. A kitchenette and full bathroom. The entire project was completed with the Total basement Finishing (TBF) system. The family was so happy and admittedly used this new space more than their living space upstairs. The homeowner told our team that they had to create a schedule of who was using the space and when. They were thrilled with the remodel. And then the inevitable happened; the basement flooded during a powerful rain.


Of course the homeowners were terrified after they had hjust invested so much into their basement. They walked around the basement taking pictures and holding their breaths waiting to find their space ruined. They knew they had purchased the installation of the best product on the market but they had hoped they would never have to find out how it held up against a flood of water. 

The homeowner immediatley contacted us and informed us of the flood. We reminded him that he made a smart investment and that he would have to wait for the basement to be dried out before an assesment of damanges could be made.

At Marshall Exteriors we knew that we installed the TBF system and we believe in it. The walls are not traditional drywall, traditional drywall simply does not survive a wet basement. The wall panels that were installed were EverLas wall panels. EverLast basement wall panels are engineered to never get moldy or rot. They cannot be damaged by moisture and won't support mold or mildew growth. Marshall Exteriors provided a 50-year transferable warranty on the EverLast Wall Panel System ensuring that the homeowner's investment was protected for years.

The concrete floors were covered in one of the best flooring solutions; carpeted tiles and vinyl-faced tiles designed that give the look of ceramic tile. These ThermalDry tiles, create a thermal break in the basement floor and a vapor barrier that prevents moisture from the concrete basement floor to reach your carpet or create humidity in your basement air under normal circumstances. During a flood like this, these tiles will dry quickly and thoroughly because they are made of completely inorganic materials meaning that they will never promote mold growth or rot like normal carpeting would.

One might never think that the ceiling could be affected in a basement flood but it can. Moisture rises and normal ceiling tiles grab and trap that moisture making them heavier and causing them to sag over time. With this basement, we knew to protect the ceiling like it was the floor. We installed TBF's Prestige ceiling tiles. These unique tiles are created out of an inorganic mineral fiber composition instead of wood fibers. The 2' x 2' x 3/4"-thick basement ceiling tiles are water resistant and have a 30-year warranty against mold and mildew. So this basement flood won't hurt the life of the new ceiling.

To complete the project a high-performance, ENERGY STAR certified SaniDry Sedona dehumidifier was installed in one of the unfinished areas to draw moisture out of the air. The water in the dehumidifier will never have to be manually drained because the system was installed to drain right into the sump pump. After the basement flood, this powerful dehumidifier will outperform any system that could have been purchased in store. The Sedona does more than just dehumidify. When it pulls air out of the remodeled basement air, it filters particles from the air as small as two microns- smaller than any mold spore or dust mite dropping. Now there is a second line of defense against mold!

All in all the new basement will out survive the waters that penetrated this new space. When the homeowner chose the Total Basement Finishing System he knew then and can be assured now that his investment is well protected.
