Crawl Space Moisture Elimination in Sewickley, PA

A homeowner in Sewickley, PA struggled with moisture issues in their crawl space that led to musty odors seeping into the upper levels of their home. After providing a free, thorough crawl space assessment, it was decided to fully encapsulate the space using our CleanSpace Encapsulation System. This system helps to control humidity, reduce energy costs, and prevent mold growth. It also keeps pests out of the crawl space, making it a safer and healthier place to be.

Waterproofing in Sewickley, PA

A homeowner living in Sewickley, PA noticed that water was seeping through the floors of their basement, so they contacted Keystone Basement Systems. A wet basement can cause structural damage and health risks to your home. Installing a durable waterproofing system prevents these issues from happening. 


Our Field Inspector Brian provided a thorough inspection of the basement. After, he presented his findings to the homeowner and recommended the WaterGuard coupled with a TripleSafe sump pump system as the best solution. WaterGuard will collect any outside water seeping into the basement. The water is then directed to the SmartSump Pump System where it's pumped back to the outside. Our crew, led by foreman Austin Stone installed the systems a few weeks after the estimate was provided. Peace of mind was restored to the homeowner knowing their basement is fully protected.

Leaking Basement in Sewickley, PA

The homeowner called us because of a leaking basement and high humidity that was causing a musty odor.  Inspector Andrew McIntire was sent to the home to inspect the issues that it was having.  The basement odor was strong and it was obvious that there was a lot of water damage.  A Sedona High Performance Dehumidifier was proposed to address this aspect of the problem.  The wet basement was caused by an age related foundation leak.  WaterGuard was proposed to address this problem.  The client was pleased with the plan and wrote a kind review online.
