Great service, low prices, excellent hardware selection…read more The staff at Altadena Hardware are friendly, helpful, and much more knowledgeable than big box stores. They will ask you about the project you're doing, and help find the right products and materials to fit the application of your work. Need to attach something to something else? They will guide you through the a-la-carte screws, nails, nuts, and bolts with expertness, making sure that the style, strength, and size of the hardware fits your project's needs. The prices for most items are competitive with big box stores-- items like PVC pipe, wood filler, and hardware are cheaper at Altadena Hardware in a side-by-side comparison to big box stores. If you purchase materials like wood or pipe, they can cut it for you for transport! The selection of paint, hardware, garden supplies, light bulbs, power tools, adhesives, and most other typical household hardware needs are excellent. Based on size, they don't stock as much lumber or appliances as big box stores. Very helpful -- they do cartridge exchange for Soda Stream!! And have many options of Soda Stream flavorings. They also sell local honey up at the cash register! Altadena Hardware is my first choice for hardware needs!

It would be good if they can use the hollow / loop pull tab which makes us easier to remove the window screen. The price has almost doubled comparing with the price before the pandemic. Today 5/26/2026, I am greatly appreciated by the excellent service provided by the staff Arron S. . He carried the window screens to our car as some of them are big. He helped to load our purchased stuff into the car. The cashier accidentally made an input error by charging us the regular price of the bark nuggets instead of the sales price, Arron helped to solve this issue quick. He was so friendly, so helpful. Arron, thanks again for your great service.
