Yes, it is possible to install hidden hinges on old cabinets. However, the process may vary depending on the type of cabinets you have and the existing hinge configuration. Here's a general overview of how you can go about it:
Assess your cabinets: Determine if your cabinets are suitable for hidden hinges. Hidden hinges, also known as European hinges or concealed hinges, require a specific type of door construction and thickness. Check if your cabinets have a frameless design or a face frame with an overlay door style. Frameless cabinets are typically more compatible with hidden hinges, but certain face frame cabinets can be retrofitted as well.
Choose the right hinges: There are different types of hidden hinges available, such as full overlay, half overlay, and inset hinges. Select the appropriate type based on the style and design of your cabinet doors.
Remove existing hinges: If your cabinets already have hinges, you'll need to remove them before installing the hidden hinges. Unscrew the old hinges from both the cabinet frame and the door.
Prepare the doors and cabinets: Measure and mark the location for the hidden hinges on both the doors and the cabinet frame. Use a template or a marking tool that comes with the hinges to ensure accurate placement. Make sure the markings are consistent on all doors and cabinet frames.
Install the hinges: Following the manufacturer's instructions, attach the hinges to the doors and the cabinet frames. Most hidden hinges require drilling pilot holes for the screws. Use a screwdriver or a drill with a screwdriver bit to secure the hinges in place. Make sure the hinges are aligned properly and the doors open and close smoothly.
Adjustments and alignment: After installing the hinges, check if the doors are properly aligned and level. If needed, adjust the hinges by loosening or tightening the screws. This will ensure that the doors hang straight and close evenly.
Test and finalize: Open and close the doors several times to ensure they operate smoothly. Check if they align properly with the cabinet openings. Make any necessary adjustments until you are satisfied with the fit and functionality.
Keep in mind that retrofitting old cabinets with hidden hinges may require some additional woodworking skills and tools. If you're not confident in your abilities, it might be helpful to consult a professional carpenter or cabinet installer for assistance.
