Crawl Space Repair in Tiffin, OH

Before, this Tiffin, OH crawl space was filthy, smelly and had a dirt floor. This combination led to a moist and unhealthy environment which would affect the rest of the home. The homeowner wanted to transfer her crawl space into a dry and healthier area. Now, this crawl space is transformed into a clean, dry and healthy area! CleanSpace liner was installed on top of the dirt floor which will act as a moisture barrier and give the crawl space a clean finish. SilverGlo insulation was installed on the walls of the crawl space. This 2 inch insulation with a radiant barrier will both insulate and reflect heat back into the crawl space. Lastly, a SaniDry Sedona was installed and placed into the area. This dehumidifier will keep humidity below 55% ensuring that the air quality will be cleaner and healthier. The combination of all of these products created the exact crawl space that this homeowner wanted!

Crawl Space Encapsulation and Support in Alexandria, OH

A homeowner in Alexandria, OH wanted to get his crawl space encapsulated and knew just who to call – Mid-Sate Basement Systems! His father had had us complete a similar project at his home a few months prior, and he highly recommended our company. So, his son decided to go with us as well. We used the CleanSpace vapor barrier to encapsulate the crawl space. There were also some sagging floors above the space, so we repaired that foundational issue with SmartJacks. The homeowner is happy with the results and now has a clean and safe home.

Crawl Space Encapsulation in Worthington, OH

Charles, the owner of a development company, was remodeling a house in Worthington, OH and needed to encapsulate the dirty crawl space. So, he called Mid-State Basement Systems for help! Our inspector, Mitch Mink, went out to do an inspection and provide a free quote for the service. Charles liked our products and warranties, so he chose to go with our company. One of our foremen, Byron Salinas, went out after that with his crew to install the CleanSpace vapor barrier, SilverGlo insulation, and a SaniDry Sedona dehumidifier. Charles is happy with the results and can continue with the rest of the remodeling.
