These distributors offer contractor pricing on pipes, fittings, water heaters, HVAC equipment, electrical panels, and more. Most have will-call counters open as early as 6 AM so you can grab parts before heading to the job site.

Do I need a contractor license to buy from wholesale supply houses?

It depends on the supplier. Some wholesale distributors like Ferguson and Platt Electric sell to anyone who walks in, while others like Pace Supply and Hajoca require a contractor account. We mark this clearly on each listing — look for the "Account Required" tag. Even at open-to-public houses, having a contractor account usually unlocks better pricing.
