10 Common Home Repairs You Can Actually Do Yourself (And When to Call a Pro)

Owning a home means dealing with little problems before they turn into big, expensive ones. This guide walks through 10 common issues you can usually handle yourself—and where the line is for calling a professional.

1. Leaky Faucet

A slow drip is annoying and wastes water, but it’s often a simple fix.

DIY:

Most leaks come from worn washers, O‑rings, or cartridges. Turn off the water under the sink, plug the drain, take pictures as you disassemble the faucet, and replace the worn parts using a matching kit from the hardware store.

Call a Pro When: You see corrosion on the valve body, the shutoff valves won’t turn, or you have very old plumbing and are worried about snapping something.

2. Running Toilet

That toilet that never stops hissing is usually more irritating than dangerous—but it drives up your water bill.

DIY: Take the tank lid off and flush once to see how things move. In many cases, you can fix it by adjusting or replacing the flapper, fill valve, or float. Universal “toilet repair kits” make this straightforward.

Call a Pro When: There are cracks in the tank or bowl, you see water around the base, or the shutoff valve or supply line is corroded.

3. Squeaky Doors

Squeaky hinges are a classic easy win for DIY.

DIY: Hold a rag under the hinges and apply a small amount of lubricant (like silicone spray or a dab of petroleum jelly). Open and close the door a few times to work it in. Tighten loose hinge screws if the door is sagging.

Call a Pro When: The door is out of square, scraping badly, or the frame is warped or damaged.

4. Slow or Clogged Sink Drain

A slow drain is often caused by hair, soap scum, or grease near the top of the drain.

DIY: Try a plastic drain snake, remove and clean the stopper, and flush with hot water. If you’re comfortable, you can remove the P‑trap under the sink (with a bucket underneath) and clear it.

Call a Pro When: Multiple drains back up at once, you notice sewage smell, or plunging/snaking doesn’t help—those can signal a deeper clog or sewer issue.

5. Loose or Sticking Door Handles

Loose knobs and latches are basic but annoying problems.

DIY: Tighten the visible screws on the door handle and strike plate. If the latch doesn’t catch, adjust the strike plate slightly or deepen the mortise with a chisel.

Call a Pro When: The door is part of your main exterior security and you’re dealing with a damaged lock mechanism you’re not comfortable disassembling.

6. Small Drywall Holes

From picture hooks to doorknob dents, small drywall damage is a perfect beginner project.

DIY: For nail and screw holes, use lightweight spackle, let it dry, sand lightly, and touch up paint. For larger holes (up to a few inches), use a self‑adhesive patch kit, joint compound, sanding, and paint.

Call a Pro When: You have large cracks, bulging, or sagging drywall that might signal moisture damage or structural movement.

7. Loose or Noisy Cabinet Doors

Cabinet doors that slam or hang crooked make a kitchen feel tired fast.

DIY: Tighten or adjust hinge screws so the doors line up. Add stick‑on soft‑close bumpers to quiet slams. Replace worn door dampers if your hinges support them.

Call a Pro When: Cabinet boxes themselves are pulling away from the wall or you see rot or water damage.

8. Wobbly Toilet Seat

A shifting toilet seat feels gross but is usually a simple fix.

DIY: Pop up the plastic caps at the back of the seat and tighten the mounting bolts. If they’re stripped or corroded, replace them with a new seat kit.

Call a Pro When: The toilet itself rocks on the floor—this often means a loose flange or deteriorated wax ring.

9. Drafty Windows and Doors

Feeling a cold draft doesn’t always mean you need new windows.

DIY: Install adhesive weatherstripping around door frames, add a door sweep, and use caulk or foam sealant to close obvious gaps around window and door trim. Heavy curtains also help.

Call a Pro When: Windows are rotting, the glass is cracked, or you see moisture between double‑panes.

10. Tripped Breakers and Dead Outlets

Some electrical issues are simple; others are not DIY territory.

DIY (Only If You’re Comfortable): If a breaker trips, unplug a few devices, reset the breaker, and see if it holds. For GFCI outlets (often in kitchens and bathrooms), press the “Reset” button.

Call a Pro When: Breakers repeatedly trip, outlets are warm, you smell burning, see scorch marks, or are unsure at all. Electricity is where you should lean heavily on a licensed electrician.
