Preventing Interior and Exterior Moisture Damage to Hardwood

Moisture Problems – Interior vs. Exterior

Protecting Hardwood Floors from Water Damage

Moisture is the number one enemy of hardwood flooring. Whether it comes from outside the home or from within, excess water can cause swelling, cupping, buckling, and even permanent damage to the wood.

At Artistry Hardwood Flooring, we emphasize both proper installation and preventive maintenance to help protect your investment. Here’s how moisture issues differ between interior sources and exterior sources, and how to address them.

 

 

1. Exterior Moisture Problems

These issues occur when water from the outside enters the home and reaches your hardwood floors.

  • Sliding Glass Doors & Entryways: Rainwater tracked in or blown in during storms.

  • Windows: Leaks from failed seals or poor flashing.

  • Roofs & Gutters: Water intrusion from roof leaks or overflowing gutters can run down walls and seep into flooring.

Prevention Tips:

  • Install proper flashing and weatherproof seals.

  • Use moisture‑resistant mats at entrances.

  • Inspect and maintain window and door seals annually.

  • Keep gutters and downspouts clear to prevent water pooling near the home’s foundation.

 

 

2. Interior Moisture Problems

These are caused by plumbing, appliances, or HVAC issues inside the home.

  • Plumbing Leaks: Broken or loose pipes in kitchens, bathrooms, or laundry rooms.

  • Appliance Leaks: Refrigerators, dishwashers, washing machines, or ice makers.

  • Bathroom Fixtures: Overflowing sinks, tubs, or toilets.

  • HVAC Issues: Condensation from air handlers or faulty humidifiers.

Prevention Tips:

  • Inspect appliances regularly for leaks or worn hoses.

  • Turn off the main water supply when leaving home for extended periods.

  • Use drip pans under appliances when possible.

 

 

3. Why Moisture is So Damaging

  • Wood naturally expands when it absorbs water and contracts as it dries.

  • Rapid or uneven moisture changes cause cupping, crowning, or gapping.

  • Severe cases can require full replacement of affected boards or sections.

 

 

4. Artistry’s Perspective

  • Our SawnPly+ Solid-Balanced Construction helps minimize movement caused by humidity changes, but no hardwood floor is waterproof.

  • Prevention, proper maintenance, and quick response to leaks are essential for protecting your investment.

 

 


Hardwood flooring can last for decades when kept in a stable, dry environment. Moisture control — both inside and outside the home — is one of the most important factors in ensuring your floors remain beautiful for years to come.
