If you have solid hardwood floors in your home in Waterville or Jordan, you have likely noticed that your flooring changes slightly throughout the year. Tiny gaps might appear between planks in the winter, only to close up again in the summer. This phenomenon is completely normal, especially in a climate like ours, but understanding the causes is key to managing it.
The Culprit: Moisture and the Climate Cycle
Solid hardwood is an organic material, and it reacts to changes in ambient humidity and temperature. This process is called expansion and contraction:
-
Winter (Contraction): During the colder months, the furnace runs constantly, drawing moisture out of the air. As the indoor air becomes dry, the wood loses moisture and shrinks. This shrinkage causes the planks to pull slightly apart, creating those noticeable gaps.
-
Summer (Expansion): During the warmer, more humid months, the wood absorbs moisture from the air, causing the planks to swell and push back together, closing the gaps.
This seasonal movement is why professionals always leave an expansion gap around the perimeter of the room during installation in homes across New Prague.
Seasonal Solutions for Minimizing Gaps
While you can't stop wood from moving, you can drastically minimize the movement by controlling the environment.
-
Invest in a Humidifier: This is the single most effective tool for managing seasonal gaps. During the dry winter months, using a whole-house or room-specific humidifier to maintain an indoor humidity level between 35% and 55% is ideal. This consistency keeps the wood from drying out excessively and shrinking.
-
Use Dehumidifiers in Summer: Conversely, if your home is excessively humid in the summer, a dehumidifier can prevent the wood from swelling too much, which could lead to cupping or buckling.
-
Avoid Quick Fixes: Resist the urge to fill gaps during the winter with putty or wood filler. When the humidity returns and the planks swell, the filler will be compressed or pushed out, leading to other, more difficult-to-fix issues. Wait until the wood is at its average moisture content (usually in spring or fall) before considering minor cosmetic repairs.
If you have large, structural gaps that persist year-round, it could indicate a more serious issue with the subfloor or installation, and it's time to call the experts at Bisek Interiors in Montgomery, MN, for an inspection.
