CarbonArmor in Sleepy Hollow, NY CarbonArmor in Sleepy Hollow, NY

This Sleepy Hollow, NY home had cracking and bowing walls that was caused from soil expansion. The homeowner was very concerned for the safety of his home and wanted to take care of the problem immediately. After doing some research, he decided to set an appointment with Connecticut Basement Systems to help find him a solution. 

Glen Kerpchar was the Sales Representative who arrived at the home the day of the appointment. He concluded that in order to fix the bowing of the walls, Carbon Armor would need to be installed. He explained the benefits of the product and the homeowner agreed that this was the best solution and quickly set an appointment for a production date.

On the day of production, Victor Alves and his crew installed the CarbonArmor. The CarbonArmor is a great product because it stabilizes your home’s foundation walls by using fiber-reinforced polymers which are 10-times stronger than steel. The ArmorLock brackets bind and secure the Carbon Armor straps to the floor joists making it a great solution, non-invasive, and ideal for stabilizing bowing and leaning walls.  

With the CarbonArmor fully installed, the homeowner now has a peace of mind of the structure of his home!
