Job Stories From Fairmont, WV
I beam in Fairmont

This homeowner called Keystone Basement Systems because he had noticed his basement wall had some cracks in it and was also bowing. That concerned him as he knew this was a fix for a professional not just some do-it-yourself kind of project because this was the integrity of his structure that was at hand here. The customer service specialist knew that she had to schedule a field inspector out to this house right away, so she made the appointment for that very afternoon. The field inspector promptly showed up for his appointment and sat down to meet with the homeowner to go over the issue at hand and all of the homeowner's concerns as to what needed to be done so that he felt comfortable in his house again.  The field inspector knew that he had to come up with not only a custom fit plan but also a very accurate and complete plan to get this home fixed and structurally sound again. The field inspector then went to work conducting his very detailed inspection of the problem area. He took all the proper measurements as well as conducted all the moisture tests and other tasks that went along with coming up with this plan. The field inspector knew that the plan had to involve some point cracking to fix the cracks that were in the walls. The plan also consisted of installing a new I-beam to ensure the structure would be safe again. Keystone Basement Systems has a proprietary steel buttress that provides unparalleled reinforcement for inwardly bowed walls. Once the field inspector had completed his inspection he then returned upstairs to speak with the homeowner once again. They went over the field inspectors' findings as well as the solution to this problem. They even went over what might take place if the homeowner decided to not go through with this project. The homeowner was very pleased with the field inspector's plan and so it was then scheduled for installation. Upon completion of installation, the homeowner was very thrilled that his house was safe again and would not be undergoing any further decaying of the walls or sagging flooring. The homeowner was so happy that he gave Keystone Basement systems a great 5-star review!
