Not all cabinets need to be new to support new countertops. What matters most is their condition, not their age.
Cabinets are usually suitable if they meet these conditions:
- They are solid and do not wobble
- Doors and drawers open and close properly
- The cabinet boxes are not sagging or cracked
- They are firmly attached to the wall and floor
- The tops of the cabinets are level or can be leveled
Even cabinets that are ten or twenty years old can be strong enough if they were well built and well maintained.
A professional installer will usually check cabinet stability and level before taking measurements. This step is important because stone countertops need a solid and even base to prevent cracking over time.
