Customer had a stairwell that just didn't feel "safe". After I pulled the carpet I found the problem...the treads were rotted!
Because of budget concerns, gutting the stairwell and starting over was out of the question. To stay within the tight budget I re-built the stairwell from the underside, added addition bracing for additional structural integrity and re-installed the original carpet. Now the stairwell is safe and strong and the customer is very pleased.
