We hired Ron to install flagstone for our back patio May, 2010. No water protection was used on our cedar siding when the flagstone was attached with a cement-based grout.
We removed this cement grout In Sep 2015 to find rotted cedar siding and layers of rotten wood below that!
Ron admits his work is the cause, but he offers only to pay 1/2 his labour, and we pay all materials, saying we should have come to him sooner if we had a problem with his work.
