Hardwood flooring adds timeless beauty and value to any home. However, as floors age, they may develop gaps between the boards, which can become unsightly and lead to additional issues such as drafts, dirt accumulation, or even damage to the wood. Homeowners often wonder whether they can fill these gaps and, if so, how to do it properly. In this blog, we will explore why gaps form in hardwood flooring, how to fill them, and the best practices to maintain the integrity of your floor.
Why Do Gaps Form in Hardwood Floors?
Hardwood floors are made of natural wood, which reacts to changes in temperature and humidity. As the environment shifts, the wood contracts and expands. This natural movement causes gaps to form over time, especially in older floors. Understanding the causes behind these gaps can help you decide whether they can or should be filled.
Environmental Changes
One of the primary reasons gaps appear in hardwood flooring is environmental change. Wood naturally absorbs and releases moisture based on the humidity levels in the room. In colder, drier months, the boards shrink, which creates visible gaps between them. During more humid seasons, the wood may expand and the gaps could disappear temporarily, only to return when the air dries again.
Age and Wear
Older hardwood floors are more likely to develop gaps due to decades of contraction and expansion. Additionally, everyday wear and tear, such as foot traffic, furniture movement, and cleaning routines, may exacerbate these gaps.
Poor Installation
In some cases, gaps can result from improper installation. If the floorboards were not spaced correctly or acclimated before installation, the wood might shift more than usual, leading to more prominent gaps over time.
How to Fill Gaps in Hardwood Floors
Filling gaps in hardwood flooring is possible and can restore the appearance of your floors while minimizing drafts and debris buildup. However, the method you choose depends on the size of the gaps and the overall condition of the floor. Below are the most common techniques for filling gaps in hardwood flooring.
Wood Filler or Putty
One of the easiest and most effective solutions for filling small to medium gaps is wood filler or putty. Available in various colors to match your floor, wood filler is an inexpensive option for DIY repairs.
How to Use Wood Filler
- Clean the Gaps: Use a vacuum or soft brush to remove any dust, dirt, or debris from the gaps.
- Apply the Filler: Using a putty knife, press the filler into the gaps. Make sure to overfill the gap slightly, as the filler may shrink slightly as it dries.
- Smooth the Surface: Once the filler has been applied, use the putty knife to smooth out the surface and remove any excess material.
- Allow the Filler to Dry: Follow the manufacturer's drying instructions. Most wood fillers take 24-48 hours to fully dry.
- Sand and Finish: After the filler is dry, sand the filled areas lightly to ensure the floor is smooth. If necessary, apply a matching finish to blend the filler with the surrounding wood.
Rope or String
For larger gaps, rope or string might be a better option. This method is particularly useful for older floors with wide gaps that cannot be easily filled with wood filler alone.
How to Use Rope or String
- Select the Right Size Rope: Choose a natural fiber rope or string that is slightly larger than the gap width.
- Apply Glue: Place a small amount of wood glue into the gap to help the rope adhere to the wood.
- Insert the Rope: Press the rope firmly into the gap using a putty knife or another flat tool. Make sure it is tight and flush with the surface of the floor.
- Trim Excess: Once the rope is in place, trim any excess that sticks out above the floor.
- Finish the Repair: You may need to stain or seal the rope to match the wood floor’s finish. This step helps blend the repair with the surrounding wood and ensures durability.
Wood Slivers
Another option for filling larger gaps is to use wood slivers. These thin strips of wood are cut to fit into the gaps, offering a more permanent solution.
How to Use Wood Slivers
- Prepare the Slivers: Cut the wood slivers from matching hardwood species, making sure they are slightly wider than the gap.
- Apply Glue: Place a small amount of wood glue in the gap.
- Insert the Sliver: Gently tap the wood sliver into the gap using a hammer or mallet. Be sure not to force it, as this could damage the surrounding wood.
- Sand and Finish: After the glue dries, sand down the sliver so that it is flush with the floor. Apply a matching finish to ensure the repair blends seamlessly with the rest of the floor.
When Should You Hire a Professional?
While many homeowners may attempt to fill gaps themselves, there are times when calling in a professional is the best option. If your floor has numerous large gaps or other significant issues like warping, buckling, or extensive damage, a professional can assess the condition of your flooring and determine the most effective repair methods.
Additionally, if your home experiences extreme fluctuations in humidity, a professional might recommend installing a humidifier or dehumidifier to stabilize the moisture levels and prevent further damage to your hardwood floors.
Preventing Gaps in the Future
Once your gaps are filled, it's important to take steps to prevent new gaps from forming. Regular maintenance, such as cleaning and proper climate control, can significantly reduce the likelihood of new gaps developing in the future.
Keep Humidity Consistent
Maintaining a consistent humidity level in your home is crucial to preventing future gaps in your hardwood flooring. Aim to keep the humidity between 30% and 50% year-round to minimize wood expansion and contraction.
Regular Cleaning
Dust, dirt, and debris can settle into gaps and cause them to widen over time. Regularly cleaning your hardwood floors with a vacuum or broom can help prevent this buildup and keep your floor looking its best.
