I've thought about purchasing a 5k gutter machine. We sell probably 450-600 feet per week. Aside from the initial gutter machine truck purchase, the coil, accessory and labor cost is really low. However, my current gutter sub only charges me $2.50/foot. After doing the cost factoring, I have a different question now; How does my gutter sub make any money or a living? Coil alone is almost $1.50/foot. Can Someone offer me some insight?
