A month ago the doorknob on our front door came off in my hand. I was told it would be impossible to repair without sourcing an identical 100 year old front doorknob. They could replace the whole lock/doorknob system with new parts but said it would probably be cheaper to buy a new door!!!! However, just with this $5 part I was able to fix my doorknob myself. I did reach out to Hardwick’s for assistance with the purchase and they were responsive and knowledgeable. I’m very glad to have found this business!

Exceptional experience
I ordered different two split doorknob spindles. a few minutes later, I decided to order a third version s as to enhance the odds that at least one would fit. To my pleasant surprise, the folks at Hardwick somehow recognized that the two orders were from the same person and going to the same place and combined orders thereby saving a good % of the order total on shipping costs. That was above and beyond expectations. I will return as a customer for sure! - Paul

Our door works now!
I bought a split spindle online from Hardwicks to replace the worn out original. Sent them a picture of the old one and they sent the new one. Fit like a charm… or at least good enough to charm me. Before I knew it, presto our front door was working again. A picture is worth a thousand words and someone on the other end interpreting it correctly, is worth more than the cost of mailing it back. Thank you. Larry Jenkins, rural NH, very rural!
