Mr. Jeff Martello inspected the bowing foundation wall and it was determined the amount of movement was unacceptable and required medium-duty reinforcement.  CarbonArmor is an ideal product to permanently reinforced the bowed basement walls.  Foreman Austin Stone installed the straps and the customer was very satisfied.

This basement had a long standing basement water issue.  The client was a painter, so he didn’t want us to address the walls after repair.  He did, however, want us to stop the basement seepage and leaking the caused the basement wall deterioration.  After our system was installed the walls will take about 15-30 days to dry out based on ambient temperature and humidity.

Job Stories From Pittsburgh, PA
Dehumidifier for Damp Basement in Pittsburgh, PA

This client called our office because they had a wet basement and high humidity.  There was a musty smell in the basement and they also had a moldy smell.  The point of water penetration in the basement was not obvious at first.  Our office sent out Mr. Jeff Martello to determine the issue as he has a vast diagnostic knowledge and capability.


After Jeff listened to the needs of the customer he performed his inspection and fund that the water penetration was coming under a bench and drawer fixture.  The wood was rotting and producing the musty and moldy smell.  He designed a system to address the needs of the home and the homeowner hired Keystone to fix the issue.


Crew Foreman Juan Pantojas III and Co-Foreman Scott Booth installed the system and solved the issue using WaterGuard and a Sedona High Performance Dehumidifier.
