Why are my kitchen cabinets peeling?

Kitchen cabinet peeling is typically caused by moisture damage, poor-quality finishes, or age-related deterioration of the cabinet surface. In Ottawa's climate with our humid summers and dry winters, this is a common issue that can often be addressed without full cabinet replacement.

The most frequent culprit is moisture infiltration around sinks, dishwashers, and cooking areas. Steam from cooking, minor plumbing leaks, or even high humidity can cause laminate to lift or painted surfaces to bubble and peel. This is especially common in older Ottawa homes where kitchen ventilation may be inadequate. Heat damage from appliances, particularly around the stove or dishwasher, can also cause adhesives to fail and surfaces to separate.

Poor-quality finishes or improper preparation during original installation often leads to premature peeling. If cabinets were painted without proper primer or if low-grade laminate was used, the coating may start failing within 5-10 years. Ottawa's temperature fluctuations - from -30°C winters to +30°C summers - create expansion and contraction that can stress poorly adhered finishes.

Age and normal wear also play a role. Most kitchen cabinets in Ottawa homes are designed to last 15-20 years, but high-use areas like handles and doors near the sink often show wear earlier. If your cabinets are approaching this age range, peeling may indicate it's time for either refinishing or replacement.

For minor peeling on painted cabinets, you might sand the affected areas, apply quality primer, and repaint - but this is temporary if moisture issues aren't addressed first. Laminate peeling often requires professional attention, as proper adhesion and edge sealing are critical for lasting results.

However, extensive peeling throughout the kitchen usually indicates underlying moisture problems or finish failure that requires professional assessment. Attempting DIY repairs without addressing root causes often leads to recurring problems within months.

Improving kitchen ventilation is crucial - ensure your range hood vents outside (not into the attic) and consider running it longer after cooking. Check for plumbing leaks around the sink and dishwasher, and ensure proper caulking around these areas.
