Job Stories From Mount Pleasant, PA
70 Year old home in Mount Pleasant

This homeowner called upon Keystone Basement Systems to help her with her 70 year old home that was now getting water up through the basement floor. Keystone sent out one of their best filed inspectors to sit with them and discuss the issue before conducting his very detailed inspection of the problem area. The field inspector knew how urgent this matter was to the homeowner after speaking with her, so he jumped right to work taking all the right very accurate measurements and conducting all the exact test that needed to be done. Once he was completed with his inspection and then returned upstairs to speak with the homeowners once again to go over everything. He explained that the plan to get this house dry again was to install a single sump pump and a 32 foot  internal french drain system that would have one cleanout.
