Understanding the causes of LVP flooring gaps
Before diving into the solutions, it's essential to understand the common causes of gaps in LVP flooring. These gaps can be attributed to several factors, including:
Temperature and Humidity Changes: LVP is sensitive to temperature and humidity variations. As these conditions fluctuate, the flooring may expand or contract, leading to gaps.
Improper Installation: Incorrect installation techniques, such as inadequate acclimatization or failure to leave proper expansion gaps, can result in gaps appearing over time.
Subfloor Issues: An uneven or unstable subfloor can cause gaps in the LVP. Addressing subfloor problems is crucial for preventing recurring gaps.
Now that we know the potential causes let's explore how to fix gaps in vinyl plank flooring.
How to fix gaps in LVP flooring
Climate Control
While there are many DIY methods for fixing gaps in Luxury Vinyl Plank (LVP) flooring, understanding the root cause is crucial for a lasting solution. One of the most common culprits for these gaps is a lack of proper climate control in your home.
Vinyl plank flooring, including LVP, is designed to be a durable and resilient option. However, it is still susceptible to expansion and contraction, just like other flooring types. The material reacts to changes in temperature and humidity, and when these fluctuations are significant, gaps can appear.
How it works:
-
Dry Seasons (Winter): When the air becomes dry, often due to heating systems, the vinyl planks can lose moisture and contract. This causes the planks to pull away from each other, creating noticeable gaps, especially at the ends.
-
Humid Seasons (Summer): Conversely, in a humid environment, the planks can absorb moisture and expand. If the expansion is uneven or if the planks are already tightly installed, this can also lead to gaps or buckling.
Proper Installation:
Problem: If the gaps are a result of improper installation, it's best to consult a professional. They can identify the installation issues and provide the necessary corrections to ensure a tight fit. One of the most common installation errors that leads to gaps, especially how to fix long side gaps in vinyl plank flooring, is not properly "locking" the planks together. LVP flooring uses a tongue-and-groove or click-and-lock system. If the installer doesn't ensure that each plank is fully engaged and locked with its neighboring planks, small gaps can appear immediately or over time.
Solution: A professional flooring installer will have the tools and expertise to address these issues. They may need to carefully remove and reinstall sections of the flooring, making sure each plank is properly clicked into place. They might use a tapping block and a rubber mallet to gently but firmly tap the planks together, ensuring the locking mechanism is fully engaged. Additionally, a professional can check for other installation errors, such as:
-
Uneven Subfloor: If the subfloor isn't flat, the LVP planks won't lie flush, which can cause them to separate.
-
Insufficient Expansion Gaps: LVP, like many flooring materials, needs room to expand and contract with temperature and humidity changes. If the installer didn't leave a proper expansion gap around the perimeter of the room, the flooring can buckle or push against itself, creating gaps elsewhere.
-
Incorrect Layout: Starting the installation with the wrong alignment can lead to misfits and gaps down the line.

Filler Strips:
Solution: A practical approach for small to medium gaps is to use color-matched filler strips or shims. These are specifically designed for LVP flooring and can be found at most home improvement stores. Carefully insert a thin, wedge-shaped strip into the gap. You may need to gently tap it in with a rubber mallet. Once the strip is in place and the gap is closed, use a utility knife to trim any excess material flush with the floor, creating a smooth and seamless finish.
Reinstalling Planks:
Solution: When gaps are extensive or a significant section of the flooring has shifted, the most permanent solution is to remove and reinstall the affected planks. This allows you to address the root cause, which is often improper installation or a lack of sufficient expansion gaps.
To do this, use a pull bar and a tapping block to carefully disengage the interlocking planks. Once the planks are loose, you can realign them and re-engage the locking mechanism, ensuring they are tightly fitted together. As you reinstall them, make sure to leave the recommended expansion gaps (typically 1/4 to 1/2 inch) around the perimeter of the room and against any fixed objects. This will prevent future shifting and gap formation. This is an effective method for addressing how to fix long side gaps in vinyl plank flooring.
Flooring Adhesive:
Solution: For gaps that have formed due to planks separating, a specialized flooring adhesive can provide a secure and long-lasting fix. Apply a small bead of LVP-specific adhesive along the edge of one of the planks with a gap.
Push the planks together and apply pressure to ensure a secure bond. You can use weights, heavy books, or even painter's tape to hold the planks in place while the adhesive cures. Immediately wipe away any excess adhesive with a damp cloth to prevent a sticky residue from being left on the surface of your flooring.
Seam Fillers:
Solution: Another option is to use a seam filler designed for vinyl flooring. These products are often available in a tube or a kit and come in a variety of colors to match your LVP. Squeeze or apply the filler into the gap, making sure it fills the void completely.
Use a putty knife or a plastic spreader to smooth the filler and ensure it is level with the surrounding planks. Once the filler has dried, you can use a fine-grit sandpaper to carefully smooth out any rough spots or excess filler, leaving a professional-looking and smooth surface. This method is particularly useful for minor gaps and seams that have separated.
