Sales representative quickly aided us in finding exact replacement (size/color) of replacement siding, the original manufacturer having gone out of business. However, when work started, their vendor provided them with wrong product. Within 1 day it was corrected and installed. A senior Manager from 123 Exterior made it right. The product was installed in 1 day by their 2 man crew who worked continuously from dawn to dusk. I would not hesitate using 123 Exteriors in the future.
