Before, this crawl space was dirty and filled with moisture which impacted the rest of the home. The dirt was unpleasant and the moisture was starting to grow mold. The homeowner was concerned for the filthy and unhealthy crawl space. He decided to contact the experts at CT Basement Systems.

Now, the crawl space is a more clean and healthy environment! CleanSpace liner was installed on the floors of the crawl space to prevent moisture to the area. Rim joist insulation was also installed to prevent unwanted air flow from coming through. This is exactly what the homeowner had wanted and is pleased with his transformed crawl space.

The house was built in 1899 and there are several cracks in the basement floor.when it rains and snows water seeps in and puddles. We have had the house tested for mold and the reports are very high. We're considering professionally sealing these cracks before proceeding with mold treatment and removal. Otherwise it'll just return. Thanks!
