No, when done correctly, removing the tile shouldn’t damage the subfloor. However, if there was pre-existing damage to the subfloor from standard use or lack of maintenance, the subfloor may need repairs. For example, if the contractors notice mold growth on the subfloor or an uneven surface, you may need more extensive services before installing new tile.

If you DIY tile removal, remove the tiles one step at a time, individually removing the tile, grout, and mortar to prevent unnecessarily damaging the subfloor. Depending on the age of your home, consider having a professional inspect the subfloor to ensure it’s in good enough condition to lay new tile.

Yes, it’s always a good idea to keep a box or two of spare tiles after a home renovation project. Tiles can crack from improper installation, heavy foot traffic, and impact from drops. Having some extra tile on hand can make replacement fast, easy, and affordable. Plus, some manufacturers might discontinue particular colors or styles, and slight variations in tile colors between batches could mean mismatched tiles even if your product isn’t discontinued. Having a few spare tiles in storage can help avoid these issues, as well.

Yes, you can install a backsplash directly onto drywall, provided the wall is properly prepped, clean, and dry. For best results, especially in kitchen areas, your walls should be made of moisture-resistant drywall, often called green board. If your current wall isn't moisture-resistant, it's recommended to replace it before installing the backsplash. For even greater protection against water damage, you can remove the existing drywall and install a tile backer board or cement board instead. While properly installed standard drywall is typically strong enough to support a backsplash, some local building codes may require water-resistant materials in kitchen areas, so it's a good idea to check.

You can attach tiles to a wall using thin-set mortar. You’ll also need a notched trowel to create grooves within the adhesive so it flattens completely when pressed in and securely holds the wall tiles. Finally, you’ll need grout to smooth the gaps between the tiles and, ideally, a grout sealer to prevent mold. While it sounds simple enough, proper planning and execution are crucial, so carefully review the steps in this guide or hire a pro tile installer to complete this project.
