Why do hardwood floors separate in winter?

During the winter months, contracting floors will often leave thin cracks or gaps between the planks. This especially happens during harsher winters when more heating is used inside the home and the air is especially dry. There's no real solution to these gaps, but they're usually not cause for concern.

Is it normal for wood floors to separate in winter?

During warm, humid summers hardwood absorbs moisture and expands. Conversely, dry winter weather causes hardwood to lose moisture and contract. Gaps and separations often concern homeowners, but this seasonal movement is completely normal.

Why is my wood floor coming apart?

Why do floor boards separate? Wood is a completely natural product and as such expands and contracts when it comes in contact with moisture and temperature fluctuations. As a general rule of thumb, when temperatures are on the hot side and moisture levels are high in the air, wood takes in the moisture and expands.

How do you fix separating hardwood floors?

To prevent large gaps in your wood floors, stabilize your home's relative humidity by using a humidifier in the winter months. Use exhaust fans and dehumidifiers to prevent too much moisture in the summer months. Small gaps less than 3⁄32 inch in width can be filled with wood filler.

Is it normal to have gaps in hardwood floors?

Generally speaking, gaps in a wood floor are normal for boards up to 2¼ inches wide if the gaps close during more humid times of the year. Normal gaps can vary in width, ranging from hairline gaps to the thickness of a quarter.

How to Keep Winter from Ruining Your Hardwood Floor

Does wood floor expand in summer or winter?

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.

Why is my floor separating from the wall?

Gaps between your walls are often caused by a home's foundation settling into poorly compacted, moisture-softened, or shrunken soils below the structure. Few issues can make a homeowner's heart drop quite like noticing a gap between the walls and floor (or ceiling) of a property.

Why are my floor boards moving?

Humidity can make your laminate floor boards shrink or expand a bit. This fluctuation in humidity levels can cause them to click loose and move, resulting in openings between the boards. Fortunately, you don't have to remove the entire floor to close these open joints.

Should you fill gaps between floorboards?

If you find that the gaps are large enough so that a nickel standing upright can slide into the gaps, then you have a problem that needs correction. If you're certain the gaps are there year-round, it's probably safe to fill them. It's best to do this during the humid season, when the gaps are most narrow.

How do you fix a floating floor that is separating?

But if damages are few, you can use caulk putty, filler, wood, or long pieces of string. These will fix the gaps and prevent drafts from through the floor at the same time. These fillers will fill in the gaps resulting to your floor's original smooth finish if done right.

Is it normal for floors to creak in winter?

In the winter floor squeaks are more prevalent because the drier conditions inside a house cause materials like wood to contract which may result in movement between floor components. The drier conditions are often the same reason trim gaps and nail pops are more common in winter as well.

Why is my wooden floor lifting?

Here's the most common reasons: Solid wood is a natural material, and as such it is very susceptible to moisture in the air and walls. If you have a damp problem in your house, or there is otherwise too much moisture in the room, the wooden floor can absorb this, and over time it will cause the boards to buckle.

Why is my floor separating from baseboard?

There are several reasons that a gap might be forming. Perhaps the contractors who built your home were inexperienced. Or maybe your floor joists are rotting due to excess moisture, causing your floors to sag. Baseboards that are separating from walls are also an early sign of foundation settlement.

What causes gap between floor and baseboard?

The gap might be because the baseboard itself is uneven. This can happen if it is badly cut such that some parts are wider than others or if there are indentations along the length of the wood. If this happens, when the baseboard is installed on the wall, there would be gaps to match the irregularities in the wood.

How much do wood floors shrink in winter?

A 5-inch-wide plank will shrink twice as much as a 2¼-inch-strip. So the size of the gap between 5-inch boards will be twice as big as the gap between 2¼-inch boards. More joints means more places to distribute gapping. Some species are more dimensionally stable than other species.

How does weather affect hardwood floors?

Believe it or not, hot weather damages your hardwood floors just as much as cold weather. The high humidity levels cause your floor to absorb moisture which causes the boards to warp, cup, or crack. The cupping is especially true if there are gaps in your floor due to the cold and lack of humidity during the winter.

Are squeaky floors a structural problem?

Are squeaky floors a structural problem? There's no need to panic. In real life, a creak or squeak is no big deal—that is, they don't signal structural damage, like termites, that could cause your floor or joist to collapse. And fixing creaky floors is fairly simple.

Will a humidifier help creaking floors?

For just a few hundred dollars, you can equip your HVAC unit with a whole-home humidifier designed to add humidity to the air when it gets dry. Keeping your home consistently between 35-55% relative humidity is the best way to protect your wood floors from shrinking, expanding, cupping, cracking, squeaking or gapping.

Can you fix squeaky hardwood floors?

Creaky floors occur when the subfloor has been separated from floor joists. You can solve this by shimming the subfloor. Wedge shims between the joist and subfloor, and use a clawhammer to tap them into place. Don't pound the shims because they could lift the floorboards and cause more squeaking.

Should floating floors move when walking on them?

Making sure the subfloor is relatively flat minimizes vertical movement of the floor when people walk on it. Note, though, that with a floating floor you will always have a certain amount of movement, as it is installed over a pad. When you walk, the pad compresses and the floor will move.
