A running toilet usually means the flapper isn’t sealing properly. Turn off the water, drain the tank, and replace the flapper (cheap and easy to find at any hardware store).

If a door sticks, it may be due to loose hinges. Tighten the hinge screws or replace them with longer ones for a stronger hold. Sometimes a light sanding on the edge of the door helps too.

Use a putty knife to apply spackle or joint compound over the hole. Once dry, sand it smooth and touch up with paint. For holes larger than a quarter, use a mesh patch first.

Old, cracked caulk lets in drafts. Remove the old caulk with a scraper, clean the area, then apply a fresh, clean bead with a caulking gun. Smooth it with your finger or a caulk tool.

Pour a mix of baking soda and vinegar down the drain, let it fizz for 10-15 minutes, then flush with hot water. For tougher clogs, use a drain snake or plunger.

Cabinet hinges loosen over time. Tighten the screws or, if they’ve stripped the wood, use longer screws or insert toothpicks with wood glue into the hole before screwing back in.
