During the winter, when homes are heated and the air is dry, wood flooring loses some of its moisture and contracts or shrinks as a result. It is normal that when relative humidity is lower than recommended, wood plank shrinks, therefore thin gaps can appear between wood planks.
Does wood flooring expand in winter or summer?
Solid hardwood floors move in sync with fluctuating conditions in their environment. They expand when the humidity increases, and contract when it decreases. During the winter months, contracting floors will often leave thin cracks or gaps between the planks.
What happens to wood floors in the winter?
During the winter, even the most carefully installed wood floors tend to dry out and shrink. … Air with a low moisture content, or low relative humidity (RH), causes wood to lose moisture. When wood loses moisture, it shrinks.
How do I keep my hardwood floors from shrinking?
Conversely, in the summertime when it becomes more humid, those same wood planks will reabsorb some of that moisture and will often return to their previous state.

Do wood floors creak more in the winter?
Creaking can have various causes, some of which are more serious than others. Hardwood floors creak more in the winter because wood expands with heat and shrinks with cold.

Do hardwood floors expand in summer?During the summer, all wood floors tend to expand because wood reacts to moisture. Air with a high moisture content (MC) or high relative humidity (RH) causes wood to gain moisture. Extreme moisture can cause cupping (when the edges raise higher than the middle of the wood planks) or even buckling.
Article first time published onHow much does wood shrink in winter?
In general, the amount of shrinking and swelling which takes place is directly proportional to moisture content changes in the wood. Wood shrinks and swells the greatest amount in the tangential direction, about half as much in the radial direction, and about 0.1% to 0.2% in the longitudinal direction, Figure 4.
Do wood floors expand?
Solid wood floors take in moisture when there is a high level of humidity in the air and let that moisture go when the humidity reduces. High humidity in the wood causes it to expand. … In a domestic setting, particularly in centrally heated homes, floors expand and contract with the seasons.
Why are my wood floors gapping?

What happens when you freeze wood?
Get the wood too cold, below freezing, and the water that is still inside the air will freeze, which can push wood fibers apart. Those fibers get pushed too much, and cracks form. (Water expands when it freezes.)
How much does wood expand when wet?

What is the best time of year to install hardwood floors?
The best seasons of the year for hardwood floor installation are the spring and fall, when there is a moderate amount of moisture in the air but the climate is not overly damp. Whenever you decide to have the floor installed, an indoor humidity level between 45-65 percent is recommended.
Do hardwood floors expand and contract?
Solid hardwoods by far, will expand and contract more than engineered products. How much will depend on the layout involved, seasonal change in relative humidity, species selection, and type of hardwood cut. For smaller areas such as 10′ x 12′ rooms, leaving 3/8″ expansion would be satisfactory.
How do you fill holes in old wood floors?

Does a house shrink in winter?
Extreme cold air reduces the moisture content in the building materials, causing them to shrink, he says. In addition to that, temperature differences between the cold outside and a home’s inside warmth — heat causes materials to expand — also contribute to the contracting.
Does heat make wood shrink?
When moist wood is heated, it tends to expand because of normal thermal expansion and to shrink because of loss in moisture content. … Wood shrinkage/expansion occurs most notably perpendicular to the grain, meaning that a solid sawn wood stud or floor joist will change in width and depth.
