Are my new kitchen cabinets warping normally in Vancouver?

Kitchen cabinet warping in Vancouver is unfortunately common due to our high humidity climate, but it's not necessarily "normal" and often indicates moisture management issues that need addressing.

Vancouver's coastal climate creates challenging conditions for wood cabinets. With humidity levels regularly exceeding 70% during our long rainy season (October through March), wood naturally expands and contracts. However, significant warping usually signals deeper problems rather than just normal seasonal movement.

Common causes of cabinet warping in Vancouver homes include inadequate ventilation around the kitchen sink and dishwasher areas, missing or failed vapor barriers behind cabinets, and poor-quality cabinet construction that can't handle our moisture levels. Older Vancouver homes, particularly those built before modern moisture management standards, are especially susceptible. If your cabinets are near exterior walls without proper rain screen assemblies, moisture infiltration from Vancouver's 1200mm+ annual rainfall could be a factor.

The type and timing of warping matters significantly. New cabinets warping within the first few months often indicate manufacturing defects or improper acclimatization before installation. Quality cabinets should be stored in your home for 48-72 hours before installation to adjust to local conditions. Gradual warping over 1-2 years might be normal settling, but dramatic changes suggest moisture problems that will only worsen.

Professional assessment is recommended if you notice doors not closing properly, visible gaps appearing, or any signs of water damage. A qualified cabinet installer can determine whether this is normal settling or requires warranty work. For moisture issues, you may need a building envelope specialist to assess your home's vapor management systems.

Next steps: Document the warping with photos and contact your cabinet supplier about warranty coverage. Check around sinks, dishwashers, and exterior walls for any signs of water infiltration. Consider running a dehumidifier during Vancouver's wet months to maintain 30-50% indoor humidity levels.
