How to Fix Gaps in Hardwood Floors

Hardwood floors are known for their timeless beauty and durability, but over time, they can develop gaps due to various factors such as humidity changes, settling of the house, or natural wood shrinkage. These gaps not only affect the appearance of your floors but can also lead to issues like drafts and increased dust accumulation. Fortunately, there are several effective methods for fixing gaps in hardwood floors, ranging from simple DIY solutions such as Redifill Putty Hardwood or Loba Easy Prime to more involved professional techniques. Here’s a comprehensive guide to help you address and repair gaps in your hardwood floors.

Understanding the Causes of Gaps.

Before addressing how to fix gaps in hardwood floors, it’s essential to understand why these gaps occur:

- Seasonal Changes: Wood naturally expands and contracts with changes in humidity and temperature. During humid seasons, wood absorbs moisture and expands, while in dry seasons, it releases moisture and contracts, potentially causing gaps.

- Age and Settling: Older homes or areas with significant settling can experience floorboards shifting and creating gaps over time.

- Improper Installation: Insufficient acclimation of wood to the environment before installation or inadequate spacing between floorboards during installation can lead to gaps as the wood adjusts.

Methods to Fix Gaps in Hardwood Floors.

1. Wood Filler

Wood filleris a quick and cost-effective solution for smaller gaps in hardwood floors:

- Choose the Right Filler: Opt for a high-quality wood filler that matches the colour of your hardwood floors. Some fillers are specifically designed for hardwood and expand or contract with the wood.

- Application: Clean the gap thoroughly to remove dust and debris. Apply the wood filler generously into the gap using a putty knife, ensuring it fills the entire space. Allow it to dry according to the manufacturer’s instructions.

- Sand and Finish: Once the filler is dry, sand the area gently to level it with the surrounding floor. Apply a matching finish or sealant to blend the repaired area with the rest of the floor.

2. Rope or Cord Filler

Rope or cord filleris ideal for larger gaps where wood filler may not be sufficient:

- Choose the Material: Select a natural fibre rope or cord that matches the size of the gap. The rope should compress easily to fit snugly into the gap.

- Installation: Clean the gap and press the rope or cord into the space, ensuring it sits just below the surface of the floorboards. Use a putty knife or similar tool to press it down evenly.

- Seal and Finish: Once in place, apply a wood sealant or finish over the repaired area. Sand lightly if necessary to ensure a smooth transition between the filler and the floor.

3. Humidifier or Dehumidifier

Addressing the underlying humidity issues can prevent future gaps from forming:

- Use a Humidifier: During dry seasons, use a humidifier to maintain a consistent level of humidity in your home. This helps minimize wood shrinkage and reduces the likelihood of gaps developing.

- Use a Dehumidifier: In humid climates or during humid seasons, a dehumidifier can help reduce excess moisture in the air, preventing wood expansion and potential floorboard movement.

4. Professional Refinishing

For more extensive gaps or floors with significant issues, professional refinishing may be necessary:

- Assessment: Hire a professional flooring contractor to assess the extent of the gaps and any underlying issues such as floorboard movement or settlement.

- Repair and Refinish: Depending on the assessment, the contractor may recommend replacing damaged floorboards, adjusting floorboard spacing, or refinishing the entire floor to ensure a seamless and durable repair.

Preventive Maintenance Tips

To minimize the occurrence of gaps and prolong the life of your hardwood floors, consider these preventive maintenance tips:

- Regular Cleaning: Keep your hardwood floors clean and free from debris that can settle into gaps and exacerbate issues.

- Avoid Water Damage: Clean up spills promptly and avoid excessive moisture on hardwood floors, as water can cause wood to swell and warp.

- Monitor Humidity: Use a hygrometer to monitor indoor humidity levels and take appropriate measures to maintain a stable environment for your hardwood floors.

Fixing gaps in hardwood floors is essential for maintaining their beauty and structural integrity. Whether you opt for DIY methods like wood filler or rope filler, address underlying humidity issues with a humidifier or dehumidifier, or seek professional refinishing services, timely repairs can prevent gaps from worsening and extend the lifespan of your hardwood floors. By understanding the causes of gaps and choosing the appropriate repair method, you can enjoy beautiful and gap-free hardwood floors for years to come.
