Customers often ask if they should change out their cabinet pulls or knobs as part of a cabinet refinishing job. You can dramatically change the look of your cabinets by doing so and the cost can be minimal. I have found one of the best places to get new hardware from is Amazon. The prices are dramatically less.
If you have single hole knobs then it is easy. If you have double hole pulls then either find the same spacing between the holes that you have now or pick something completely different and we can fill the existing holes and drill new ones.
Be careful. Often packaging says a particular spacing dimension and it actually turns out to be different. If for example you find a cabinet pull at Lowes that you like, I would buy one, take it home and make sure it lines up correctly before buying a box full. I bought an entire box of cabinet pulls at Menards once and every package in that box was marked 3 and 1/2 inches but every one was a different size. Can be very frustrating.
If you are changing the spacing of the knob or pull, it is one of the first things that is done in the shop so you will want to make that decision before having the cabinet refinishing process started so the holes can be filled with an epoxy filler and sanded down.
