You should regrout tile every 10 to 15 years, provided it is well-maintained with regular cleaning and sealing. Over time, grout can deteriorate due to exposure to moisture, foot traffic, and the use of cleaning agents. If you start to see cracks, discoloration, crumbling grout, or loose tiles, it’s a sign that regrouting is needed sooner.
The most effective way to clean grout involves a combination of powerful cleaning agents and the right tools. Using a dedicated grout brush intensifies the cleaning process, ensuring a deep clean. Create a powerful homemade solution by mixing baking soda, hydrogen peroxide, and dish soap to break down deeply embedded dirt. After cleaning, reseal the grout to lock in protection and maintain its appearance.
You can't regrout tile without removing the existing grout and expect good, long-lasting results. You must replace the old grout when it begins to crumble and fail. New grout cannot properly adhere to existing grout, meaning moisture will still reach the damaged layer and cause additional water damage, which will be more costly to deal with in the long run.
Visible indicators, such as cracks, stains, chipping, and mold growth, signal that your grout is compromised and no longer maintains its bonding strength. If you notice these issues, cleaning alone won't restore the grout's integrity. In such cases, consider complete or partial regrouting to preserve your surfaces and prevent further damage.
