Job Stories From Wilmerding, PA
Mold in Wilmerding

This homeowner called into Keystone Basement Systems after going to HomeAdvisor and not feeling comfortable with some of the other companies she saw. She was concerned for her health as her wet basement was now getting moldy. Keystone sent out one of their finest field inspectors to evaluate the issue at hand and come up with a plan to put her mind at ease and make sure the house was safe again. Keystone's field inspector performed a in-depth inspection of the area and came up with the plan to install a internal french drain system along with Jopax mold wash and a window guard to prevent the water from coming in through the window. The plan also included to install a sump pump and a external discharge line.   

Internal french drain

This homeowner called Keystone Basement Systems because she noticed her basement was getting a odd odor and was a little moist. Keystone then sent out their best field inspector to evaluate the issue at hand in order to come up with a plan to fix it. Once the field inspector was complete in his findings he sat down with the homeowner to discuss the plan and answer any questions they might have had. The plan was to install a internal french drain with 1 cleanout and some new downspouts with extensions, and also a Sedona dehumidifier.  This plan was accurately executed and the basement was dry again and the homeowner was thrilled.   

Banquet hall in need of help

This commercial property owner got onto HomeAdvisor in search of a company that could help his banquet hall. He had some minor cracks in a wall and was taking on a trickle of water when it rained, but seeing as how he served food he knew this was not healthy and needed help as soon as possible! Keystone Basement Systems sent out one of their filed inspectors to discuss this issue and to also perform a thorough inspection of the issue at hand. One he entered the area that was having the issue he noticed a smell of mildew. He knew that his plan needed to take care of that problem as well. The field inspector conducted his inspection and came up with a great plan to help this business owner. The plan included having the cracks filled and then installing some WaterGuard as well as having a Sedona dehumidifier.
