Our vinyl plank joints are collecting dirt — is that install gap or product issue?

Dirt collecting in vinyl plank joints is typically an installation issue - either the planks weren't properly locked together during installation or the subfloor preparation wasn't adequate, creating uneven surfaces that prevent tight seams.

Proper vinyl plank installation requires planks to be fully engaged with no visible gaps between pieces. When installed correctly, the locking mechanism creates a virtually seamless surface where dirt can't penetrate. However, if planks weren't completely clicked together or if the subfloor had high/low spots that weren't corrected, you'll get gaps that act like dirt magnets. Temperature changes can also cause poorly installed planks to separate slightly, especially if the flooring wasn't properly acclimated before installation.

Subfloor preparation is critical for vinyl plank success in Ottawa's climate. The subfloor must be level within 3/16" over 10 feet, clean, and dry. Any debris, old adhesive, or uneven areas will prevent planks from seating properly. Additionally, if the installation didn't include proper expansion gaps at walls (typically 1/4"), the flooring might be binding and creating stress that opens seams.

Product quality can also be a factor - lower-grade vinyl planks may have inconsistent locking mechanisms or may shrink more than expected. However, premium LVP products like those we typically install are engineered to maintain tight seams even with normal expansion and contraction.

To address this issue, you'll likely need a professional assessment to determine if planks can be re-engaged or if sections need reinstallation. Attempting to force planks back together without addressing the root cause often leads to buckling or damage. For a proper evaluation of your vinyl plank installation, request a consultation from Ottawa Floor Install to determine the best repair approach.
