Hardwood flooring is a timeless choice for homes, admired for its natural beauty and durability. However, as hardwood floors age, gaps between the planks can start to appear, often due to changes in humidity, natural wear and tear, or the settling of a house. These gaps can be both unsightly and problematic, potentially leading to drafts, dirt accumulation, and further damage. The good news is that gaps in old hardwood flooring can often be filled, restoring both the appearance and functionality of the floor. In this blog, we'll explore why these gaps occur, the best methods for filling them, and how to maintain your hardwood floors to prevent future gaps.
Why Do Gaps Appear in Hardwood Floors?
Understanding why gaps develop in hardwood flooring is the first step in determining the best way to address them. Gaps are a common issue in older hardwood floors, and they can result from several factors.
Seasonal Changes and Humidity
One of the most common reasons for gaps in hardwood floors is seasonal changes in humidity. Wood is a natural material that expands and contracts with changes in moisture levels. During the dry winter months, the wood can shrink, causing gaps to appear between the planks. In the humid summer months, the wood may expand again, sometimes reducing the gaps but not always eliminating them entirely.
Settling of the House
Over time, houses settle into their foundations, which can cause the flooring to shift slightly. This settling can create gaps between the planks, especially in older homes where the floors have been in place for many years.
Wear and Tear
Daily wear and tear can also contribute to the development of gaps in hardwood flooring. As people walk on the floors, the constant pressure and movement can cause the wood to shift slightly, leading to gaps over time.
Methods for Filling Gaps in Hardwood Flooring
If your hardwood floors have developed gaps, there are several methods you can use to fill them. The right method will depend on the size and cause of the gaps, as well as your personal preferences for the appearance of the finished floor.
Wood Filler
Wood filler is a popular choice for filling small to medium-sized gaps in hardwood flooring. Available in a variety of colors, wood filler can be matched to the color of your floor for a seamless look. To apply wood filler, simply squeeze it into the gaps, smooth it with a putty knife, and allow it to dry. Once the filler is dry, you can sand it down to ensure it is flush with the surrounding wood and apply a finish if necessary.
Pros and Cons of Wood Filler
The main advantage of wood filler is its ease of use and ability to blend with the existing floor color. However, wood filler is not flexible, so it may crack or fall out if the floor continues to expand and contract. This method is best for filling gaps that are unlikely to change size significantly over time.
Rope and Stain
For larger gaps, some homeowners opt for a more traditional method: filling the gaps with a thin rope, often referred to as jute or sisal rope, and then staining the rope to match the floor. This method works well for wider gaps where wood filler might not be sufficient. The rope is flexible, allowing it to expand and contract with the floor, which helps prevent it from falling out or cracking.
How to Use Rope and Stain
To fill gaps with rope, select a rope that is slightly larger than the gap to ensure a snug fit. Press the rope into the gap, using a putty knife to push it down if necessary. Once the rope is in place, stain it to match the color of your floor. This method creates a rustic, textured look that can add character to older floors.
Sawdust and Glue
Another effective method for filling gaps in hardwood flooring is to create a homemade wood filler using sawdust and wood glue. This method is particularly useful for narrow gaps and allows for a custom color match, as you’ll be using sawdust from the actual floor.
Mixing Sawdust and Glue
To create this filler, collect sawdust from sanding the floor or from a similar species of wood. Mix the sawdust with wood glue until it forms a thick paste, then press the mixture into the gaps. Allow it to dry thoroughly before sanding the area smooth and applying a finish. This method works well for small gaps and offers a durable, flexible solution.
Maintaining Hardwood Floors to Prevent Gaps
Once you've filled the gaps in your hardwood floors, it's important to take steps to maintain them and prevent new gaps from forming.
Control Humidity Levels
Since changes in humidity are a major cause of gaps in hardwood floors, controlling the humidity levels in your home is key. Use a humidifier in the winter to add moisture to the air and prevent the wood from shrinking. In the summer, an air conditioner or dehumidifier can help reduce excess moisture and prevent the wood from expanding too much.
Regular Cleaning and Maintenance
Keep your hardwood floors clean and well-maintained to reduce the risk of damage. Sweep or vacuum regularly to remove dirt and debris that can scratch the floor or get lodged in gaps. Use a hardwood floor cleaner to remove stains and protect the finish.
Avoid Excessive Moisture
Water is the enemy of hardwood flooring, so be careful to avoid excessive moisture. Wipe up spills immediately and avoid using a wet mop on hardwood floors. If your floors are in a high-moisture area, such as a kitchen or bathroom, consider placing rugs or mats in strategic locations to protect the wood.
