When you ask the hardwood flooring experts what the most common cause of floor gapping is, they will tell you – moisture. Whether it is too much moisture or not enough, the level of humidity in your home can have a major effect on your hardwood floors.
Water Underneath The Floor
The moisture level doesn’t end within the individual wood planks. Access moisture and water can actually seep underneath the hardwood floor as well. When water or moisture gets under hardwood floors, it can cause damage to the flooring surface and cause flooring gapping.

What About Wide Gaps?
For wide floor gaps it may be necessary to fix them with wood shims, narrow strips of wood or rope. Each of these processes are a little more time consuming but are a more permanent and are often more attractive looking than using a putty or paste. In any of these options, be sure the floorboards are secure before proceeding. Measure narrow strips of wood or rope to the length of the gap and using an adhesive. Then place the wood or rope in the gap. If using wood, weight it to dry.
How to stop gaps in hardwood floors?
You can choose to use room humidifiers or furnace humidifiers; both will help minimize the chance of gaps showing up in your hardwood floors down the road.
What filler to use for gaps?
Using fillers – such as putty, powdered filler, which is mixed to a putty or paste form, or even caulking – resolves gaps if done properly. It is best to use fillers with few narrow gaps. However, as humidity changes and the floor expands and contracts, the filler may actually be forced out.
What does it mean when a floor has too many gaps?
Too many gaps, extremely wide gaps, or a floor that has movement (creaking or loose boards) may require extensive repair. One thing to be aware of when determining the extent of a floor gap is to know whether or not the gap is considered normal. This means it may close when the weather changes.

Can you use wood strips to fill gaps?
Further, if you’re using wood strips or shims as the filler for fixing a floor gap, be sure to fill the floor gap when the weather is most humid, as this will be when the gap is the smallest and will lessen the likelihood of the wood pieces or shims from splitting or cracking when the wood expands. Once the wood or rope fillers have dried you can finish off with sanding, in the case of the wood strips, and stain to match the finish of the hardwood floor.
What Causes Hardwood Gaps in Winter?
Gaps first occur in winter because this is the first time humidity is very low, which draws all excess moisture out of the wood. During installation, the moisture content on the surface hardwood wood is usually higher than the subfloor, which has been through many seasonal cycles.
How to keep humidity in house?
To avoid seasonal gaps, you can limit the variation in humidity in the house. In the winter, this can be achieved with a whole house humidifier that connects to the furnace. Note that these systems can have drawbacks if they put too much humidity in the air, including promoting mold growth in vents. You will want to make sure your ductwork is very clean before installing a whole house humidifier, but once installed, they can work wonders. During the summer, make sure to run your air conditioner system to draw humidity out of the air, keeping the hardwoods at a relative constant point all year. A good target humidity level is 40-50%.
What happens if you don't acclimate wood?
If you did not properly acclimate the woods, the winter may have pulled a very large amount of moisture out of the boards – an amount that will never fully return to the wood in the spring and summer. In this case, gaps may become smaller in spring and summer, but they will persist, and may get even larger in the following year. ...
When do gaps in wood become smaller?
In this case, gaps may become smaller in spring and summer, but they will persist, and may get even larger in the following year. After two full seasonal cycles, the hardwood will reach an equilibrium with the subfloor and environment and the gaps in the wood will be minimized.
Can you get gaps in a subfloor?
It is useful to note at this point that some web sites will suggest that if you have perfectly matched subfloor and hard wood moisture levels at installation, you will not get any gaps. This is not entirely true. Not all wood types respond the same way to moisture, and it is possible that when moisture levels drop, your subfloor could contract at a slower rate than the surface hardwoods, leaving gaps.
Do you need to clean ductwork before installing a humidifier?
You will want to make sure your ductwork is very clean before installing a whole house humidifier, but once installed, they can work wonders. During the summer, make sure to run your air conditioner system to draw humidity out of the air, keeping the hardwoods at a relative constant point all year.
How to prevent cracks in hardwood floors?

Why does wood expand?
Wood is a natural material that responds to changes in humidity and temperatures. Higher levels of humidity during the summer or rainy season causes wood to absorb moisture and expand.
How does wood flooring respond to humidity?
When wood absorbs moisture, it expands, or swells up, and when it loses moisture, it shrinks, or contracts. Wood flooring responds to the conditions immediately surrounding it. It takes in moisture from the air in your home, or loses it if the Relative Humidity (RH) of the home drops. What is Relative Humidity? Relative humidity is the amount of water vapor that is in the air, expressed as a percentage of the maximum amount of water the air can hold at the same temperature. Warm air holds more water than cold air, so hot days are typically far more humid than cold days. In winter, the air outside is generally dry and cold and the RH inside of people’s homes drops, which is why I get more calls about this issue at this time of year. Not only do RH swings affect wood flooring, but they can also affect cabinetry and trim.
What is the RH of wood flooring?
The acceptable RH range for wood flooring in the Northeast USA is between 30% - 50%. If the RH in your home is below 30%, you can be certain that you will see gaps in your wood flooring, and probably cracks as well! Humidity controls can be installed in your HVAC system to control the RH level, which can greatly improve the low RH that most people experience in their homes in the winter time. If you don’t have an HVAC system, Humidifiers can help to bring up the RH inside the home in the winter. Humidifiers are not a permanent solution to winter-time dryness because a high interior RH when it is very cold outside can be bad for a home as it can lead to condensation and mold formation. Some simple ways to at least increase the RH levels in your home in the winter are to leave the dishwasher open after running it, and after showering, to leave the bathroom door open! If you have problems with excessive ventilation (lots of air entering home from outside), weatherization and home energy audits can help to identify leaky areas, and they will suggest sealing efforts to reduce ventilation and the drying effect it has in the home in winter.
What does "if you change the conditions, you change the dimensions" mean?
Dimensions refers to the actual dimensions (measurements) of the individual boards themselves. Maintaining constant conditions in the home is critical to the success of a hardwood floor.
How does cold weather affect heating?
Cold winter months require more heating. Dry air is forced into the environment. Moisture is now removed from not only the environment but the cells or pores of the hardwood. Contraction occurs. Ventilation also plays a major role in this winter-time drying. When you bring cold outside winter air into a house and then warm it up, the RH of that air drops significantly. Old, leaky homes with old windows will present a real challenge keeping the RH inside the home at a constant level. Oftentimes people don’t realize how dry the air in their house becomes in winter!
What is relative humidity?
Relative humidity is the amount of water vapor that is in the air, expressed as a percentage of the maximum amount of water the air can hold at the same temperature. Warm air holds more water than cold air, so hot days are typically far more humid than cold days. In winter, the air outside is generally dry and cold and the RH inside ...
Can you rip out old hardwood flooring?
If you own an old house that had old, gapped flooring when you purchased it, there is not really too much to do about it unless you want to rip out the floor and install a new one. Incorrect nail spacing, improper acclimation and species/board width selection all can contribute to seasonal gapping and floor movement, all of which which you cannot do anything about if you have purchased a home with existing hardwood flooring.
Can you prevent wood flooring from losing moisture?
Purchase an inexpensive hygrometer to keep track of the Relative Humidity (RH) in your home! At the end of it all, hardwood flooring is made from wood, an organic material, and science is science. There is no way to prevent winter and there is no way to prevent wood from losing some moisture in the winter.
What to use to fill gaps in plank floor?
Filling large gaps with natural-fiber rope is a traditional method commonly used on wide plank floorboards in very old homes. While the rope doesn't look like wood, you can stain it to blend with the floorboards, and the filled gaps will be much less noticeable than the dark, empty gaps. Be sure to use natural rope, such as jute or cotton, because synthetic rope won't accept a stain.
How to secure rope to wood?
String out the rope along the gap, then force it into the gap with the 5-in-1 tool or a putty knife, stopping when the rope is flush with (or slightly below) the wood surface. Trim the rope as needed with a sharp utility knife. To help secure the rope, apply a bead of wood glue in the crack prior to placing the rope.
When to check for gaps in wood flooring?
Check your flooring during the humid season, when the wood is most swollen and the boards are at their tightest. 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.
Why does wood shrink when it dries out?
