Here is a list of the top 10 common household repairs, along with advice on when it might be time to call a professional:

1. **Clogged Drains**
*DIY Tips:* Use a plunger or a drain snake for minor clogs. Baking soda and vinegar can also help clear drains.
*Call a Pro:* If the clog persists or multiple drains are affected, it might be a sign of a more serious blockage or issue, such as tree root intrusion, requiring a professional plumber.

2. **Leaky Faucets**
*DIY Tips:* Often caused by worn-out washers or seals. Turn off the water supply and replace the washer or o-ring.
*Call a Pro:* If the leak continues after replacing parts, or if you're uncomfortable disassembling the faucet, it’s best to consult a plumber.

3. **Running Toilet**
*DIY Tips:* Check the flapper, fill valve, and float for damage and replace as necessary.
*Call a Pro:* If the toilet continues to run despite troubleshooting, or if there are leaks around the base, it's wise to call a plumber.

4. **Wall Cracks**
*DIY Tips:* Small cracks can often be filled with spackle, sanded, and painted over.
*Call a Pro:* If the cracks are large, growing, or accompanied by structural issues like doors or windows sticking, consult a structural engineer or professional contractor.

5. **Flickering Lights**
*DIY Tips:* Check and tighten loose bulbs or replace them if necessary. Ensure all connections are secure.
*Call a Pro:* If multiple lights flicker or there is a buzzing sound, this could indicate an electrical issue, which should be handled by an electrician.

6. **Broken Garbage Disposal**
*DIY Tips:* Check for jams and use a hex wrench to manually turn the blades if necessary. Press the reset button.
*Call a Pro:* If it's not working or making unusual noises even after troubleshooting, you might need a professional’s help.

7. **Heating/Cooling Issues**
*DIY Tips:* Change filters and check thermostat settings for basic issues.
*Call a Pro:* For persistent problems or if the system isn’t functioning properly after basic maintenance, hire an HVAC technician.

8. **Peeling Paint**
*DIY Tips:* Sand down the peeling areas, prime, and repaint with quality paint.
*Call a Pro:* For large areas or high walls/ceilings, professional painters can ensure a safer and more polished job.

9. **Faulty Outlets/Switches**
*DIY Tips:* Ensure breakers are on and outlets are not overloaded before testing or replacing defective receptacles.
*Call a Pro:* For persistent issues, frequent tripping, or if you are not comfortable working with electricity, contact an electrician.

10. **Roof Leaks**
*DIY Tips:* Temporarily patch leaks with roof tape or tarping until a more permanent fix can be made.
*Call a Pro:* Roof repairs can be dangerous and complicated. It’s best to hire a roofing professional for a thorough inspection and repair.

When in doubt, always prioritize safety and consider hiring a professional to avoid injury or further damage.
