Re-grouting is something you wouldn’t want to do very soon. It’s difficult especially if you are staying in the house. While there are no fixed criteria to determine, there are a number of factors which can impact the need or frequency for re-grouting. This usually involves the number of family members, the frequency of usage, presence of kids or pets, the foot traffic etc. All these things must be considered along with the quality of grouts you have at your home. As a general suggestion, you must daily clean your floor with a natural cleaning solution.
