Any wholesaler can promise you a decent supply of parts. But Rundle-Spence isn't just any wholesaler. We're the wholesaler who has the contractor's back. We have a huge inventory of parts and products and a knowledgeable staff who will work with you to find the best solutions. What's more, we're locally owned, so we can make decisions quickly in order to respond to your needs.

All orders received between 7 a.m. and 5 p.m. will be delivered free the next day, within a 50-mile radius. But when you're in a pinch, our rapid response team is there for you with after-hours and emergency deliveries.
