This Durham crawlspace clearly had a lot of issues before we arrived to transform this space. The traditional fiber glass insulation was falling apart, there was a dirt floor that made the area look unwelcoming, and there was air and moisture entering the crawl space. The homeowners wanted to upgrade their crawl space to have it be more welcoming and efficient so they would not have to worry about any consequences that happen with a poorly maintained crawl space. They decided to set an appointment with Connecticut Basement Systems who are the experts in crawl space repairs. 

Doug Wheeler was the Sales Representative who arrived at the home to give a free home evaluation. He concluded that CleanSpace Liner paired with a SaniDry Sedona would be the perfect solution for these Durham homeowners. After explaining the benefits of each product and having the homeowners understand how these products will improve their home’s efficiency, they quickly scheduled for a production date.  

Garfield Sanderson and his production team installed the products efficiently and professionally. The CleanSpace Liner acts as a moisture barrier to prevent any unwanted air or water from entering the crawl space. Wrapping the piers would also be beneficial to the crawlspace, as seen in the after photo. The SaniDry Sedona will keep the humidity low in the crawl space which will prevent any mold growth. 

The crawlspace is now a much healthier environment and the homeowners were impressed with the crawlspace transformation. The homeowners were very pleased with the work that was done by Connecticut Basement Systems.
