Well-built custom cabinets should last 30 years or more, regardless of who installs them.
Longevity is driven by construction quality, materials, and finish, not installation method.
Custom cabinets built with plywood boxes, durable joinery, and quality hardware are designed to withstand decades of use. Proper finishes protect against moisture, wear, and cleaning products, while modern soft-close hardware reduces stress on cabinet components over time.
Installation quality does matter in the sense that cabinets must be installed level, secure, and properly supported. However, that doesn’t require specialized cabinet installers — it requires care and attention.
When cabinets are installed correctly, their lifespan is determined almost entirely by how they’re built. That’s why investing in solid design and fabrication upfront pays off long-term.
Custom cabinets aren’t a disposable product. When done right, they’re a long-term part of the home.
