7. Re-Caulk Kitchen and Bathroom

Re-caulking sinks, bathtubs, and countertops is a simple project that prevents water damage and instantly refreshes the look of kitchens and bathrooms. Start by removing old, cracked caulk with a utility knife.
Choose silicone caulk for areas exposed to moisture, while acrylic latex works well around sinks and backsplashes. Apply a steady bead, then smooth with a damp finger or caulk tool. This quick update helps seal out water and mold, preserving surfaces. For a detailed, step-by-step guide, refer to This Old House’s caulking tutorial.
