Toronto experiences high humidity levels, especially during the summer months. While this may not seem like a major concern for homeowners, excessive moisture can significantly impact kitchen cabinetry. Wood is a natural material that expands and contracts with humidity changes, leading to warping, cracking, and even mold growth. If you’ve noticed cabinet doors sticking, peeling finishes, or an overall decline in quality, your kitchen cabinets might be suffering from moisture-related damage.

At Magna Custom Cabinetry & Design, we understand the importance of maintaining high-quality cabinets that last for years. In this guide, we’ll explore how Toronto’s humidity affects your kitchen cabinetry and what steps you can take to protect your investment.

How Humidity Affects Kitchen Cabinets?

Moisture-resistant custom kitchen cabinetry in Toronto

Wood is hygroscopic, meaning it absorbs and releases moisture depending on the surrounding environment. In a city like Toronto, where humidity levels fluctuate throughout the year, kitchen cabinetry is constantly exposed to varying conditions. Here’s how humidity impacts your cabinets:

1. Expansion and Contraction

When humidity levels rise, wood absorbs moisture and expands. This can cause cabinet doors to swell, making them difficult to close properly. During winter, when the air becomes drier, the wood contracts, potentially leading to gaps and cracks in the material.

2. Warping and Buckling

Prolonged exposure to high humidity can cause cabinet panels to warp, twist, or buckle. This affects both the appearance and functionality of your cabinetry, making it difficult to maintain a seamless kitchen aesthetic.

3. Peeling and Delamination

Humidity can cause the finish or veneer on cabinets to peel or separate. If you have laminated cabinets, excessive moisture can weaken the adhesive, leading to unsightly bubbling and peeling.

4. Mold and Mildew Growth

A humid environment creates the perfect breeding ground for mold and mildew. If left unchecked, mold can damage the integrity of your cabinetry and pose health risks to your family.

Ways to Protect Your Kitchen Cabinets from Humidity Damage

While Toronto’s climate is beyond your control, there are several steps you can take to prevent humidity from damaging your kitchen cabinetry:

1. Maintain Indoor Humidity Levels

Keeping your home’s humidity levels between 35% and 50% can help prevent excessive moisture absorption. Use a hygrometer to monitor humidity levels and adjust accordingly.

2. Use a Dehumidifier

A dehumidifier is an excellent investment, especially during summer when Toronto’s humidity is at its peak. It helps reduce moisture levels in the air, keeping your cabinets dry and in good condition.

3. Ensure Proper Ventilation

Good airflow is essential in preventing humidity buildup in the kitchen. Install an exhaust fan above the stove and ensure it vents outside, not into the attic. Open windows when cooking or running the dishwasher to allow excess moisture to escape.

4. Go for High-Quality Materials and Finishes

When choosing kitchen cabinetry, opt for moisture-resistant materials like plywood instead of particleboard, which is more susceptible to swelling. Magna Custom Cabinetry & Design uses premium finishes and sealants to enhance durability and moisture resistance.

5. Wipe Down Surfaces Regularly

Spills and steam from cooking contribute to kitchen humidity. Regularly wipe down cabinet surfaces to prevent moisture buildup. Avoid using excessive water when cleaning and opt for a damp cloth instead.

6. Seal Gaps and Edges

Over time, small gaps may form in cabinetry due to contraction. Sealing these gaps with caulking or wood filler prevents excess moisture from seeping into the material.

7. Keep Cabinets Away from Direct Heat Sources

Placing cabinets too close to ovens, dishwashers, or steam-generating appliances can expose them to excess heat and moisture. Ensure there is adequate spacing to minimize damage.

Signs It’s Time to Repair or Replace Your Kitchen Cabinets

Even with the best care, prolonged exposure to humidity may require cabinet repair or replacement. Here are some signs that indicate it’s time to upgrade:

  • Persistent warping or swelling that affects functionality
  • Visible mold or mildew damage
  • Peeling or bubbling finishes that cannot be restored
  • Cabinet doors that no longer close properly
  • Structural weakening due to prolonged moisture exposure
