Next Day Delivery Details

Doheny’s is pleased to offer free next day delivery at no additional charge to most of the US for all Doheny's brand chemicals and many of our most popular swimming pool supplies. Next Day Delivery Service does not mean Next Day Air, but simply that your qualifying products will be shipped from the warehouse closest to you resulting in delivery the next day.

Some details regarding this service:
Other than for Pleasant Prairie, Wisconsin, not all products are stocked at all locations and therefore not available for next day delivery. Only those items with a Next Day Delivery designation on the product page can be expected to arrive the next day and orders must be placed by 4 PM local time (exceptions include areas serviced by our Texas and Tennessee warehouses: Texas by 2:30 PM and Tennessee by 3 PM).

If you reside in the next day delivery area served by our Pleasant Prairie facility, order in-stock products and place your order by 4 PM CT you should receive your order the next day (except Saturday or Sunday). This applies to products even if they do not have a Next Day Delivery designation.

Because next day delivery is not guaranteed for standard service and residential deliveries are made only Monday through Saturday though Saturday delivery is not guaranteed, there is a chance that our product will not arrive the next day. While we try our best, unexpected demand can cause products to occasionally be out of stock or create a warehouse backlog that also can prevent shipment the day of the order.
