10 Small Home Repairs You Should Never DIY
DIY is great — until the video skipped the part where the drywall crumbles, the shutoff valve won't close, or the light fixture wire is unlabeled. Here are ten common small projects where the DIY math almost never works out, and what to hire out instead.
1. Anchoring a heavy TV or mirror to drywall
The failure mode isn't the mount — it's the drywall. Anything over 40 lbs needs to hit at least one stud, and stud spacing rarely matches the mount holes. A handyman does this in 30 minutes with the right anchors and a stud finder for $150–$275.
2. Patching a drywall hole larger than a fist
Small nail holes are easy. Anything bigger requires a backer, mesh tape, three coats of compound with dry time between each, and paint blending. The DIY version is almost always visible from across the room.
3. Replacing a toilet
The physical install is easy. The problem is the wax ring, the flange condition, and the shutoff valve — any of which can turn a two-hour job into a plumber emergency. Hire this out for $250–$450 and it's done right.
4. Hanging a chandelier or heavy light fixture
Above 25 lbs, the electrical box has to be rated for the weight. The DIY version usually skips that check, and the fixture eventually pulls the box out of the ceiling. This is a $125–$225 handyman visit for peace of mind.
5. Faucet replacement
The stop valves under a 15-year-old sink are the danger. If they don't turn off, or the packing gives out when you touch them, you now have a plumbing project instead of a faucet swap.
6. Installing a garbage disposal
The mount is fine — it's the drain plumbing that gets you. Getting the outlet, dishwasher inlet, and trap heights to line up almost always requires cutting new PVC.
7. Repairing rotted exterior trim
By the time you can see the rot, it's spread. Proper repair means removing the affected trim, checking the sheathing, priming all six sides of the replacement piece, and back-caulking the joint. YouTube skips most of that.
8. Recaulking a shower or tub surround
Removing old caulk cleanly is 80% of the job, and it's tedious. Skip it and the new caulk fails in six months. A pro does it in an hour with the right tools.
9. Replacing an exterior door threshold
The threshold sits in a bed of sealant, and modern doors have adjustable sweeps that need to be dialed in against the weatherstripping. Miss it and you have air and water leaks all winter.
10. Anything involving "just a little" electrical
Swapping a fixture on existing wiring is fine for a handyman. Adding a new outlet, moving a switch, or troubleshooting a dead circuit is licensed electrical work. Don't chase a dead circuit in your basement on a Saturday.

- Isn't DIY always cheaper?
- Only if the DIY works. When it doesn't, you pay for both the failed materials and a pro to fix the damage. On small home repairs, hiring out is often the same cost or less than a botched DIY.
- What small projects are actually good for DIY?
- Cosmetic paint touch-up, changing outlet cover plates, minor caulking, switching to smart bulbs, tightening cabinet hardware, and swapping a showerhead are all reasonable weekend projects.
