Small details make a big difference.
The old caulking around this vanity backsplash was cracked, separating from the wall, and already collecting dirt and moisture. Everything was cleaned properly, old material removed, and fresh silicone applied for a cleaner finish and better water protection.
A lot of homeowners underestimate bathroom caulking, but water behind a backsplash can slowly damage drywall, vanity sides, and even create hidden mold problems over time.
Quick DIY tip:
1. Never apply new caulk over loose or dirty old caulk
2. The surface must be completely dry before applying silicone
3. Smooth the bead right away before it skins over
4. Less caulk usually looks better than too much caulk
Small repair. Cleaner look. Better protection.
