A toilet that won't stop running is usually a flapper or a fill valve. Most homeowners can fix it in under an hour if the shutoff valve works.
Setting a new toilet on a sound flange is a realistic DIY. A broken flange, a rotten subfloor, or a nonstandard rough-in is a plumber's job.
A drip from the spout or a leak at the handle is usually a cartridge, washer, or O-ring. The trick is matching the parts, not the plumbing.
Swapping a plug-in disposal on an existing sink is a realistic DIY. Hardwiring a new circuit, or a unit that leaks from the bottom, changes the call.
This is the project where the permit and the fuel type matter more than the tank. Gas, venting, and a new circuit are pro work for almost everyone.
One slow sink is a plunger and maybe a snake. Several fixtures backing up at once is a main-line problem, and that is a plumber.
Nail holes and doorknob dings are a beginner job. A large hole, or any hole from water, is where people get into trouble.
Floating vinyl plank is one of the better weekend floor projects, as long as the subfloor is flat, dry, and you leave the expansion gap.
Fresh grout makes old tile look new. It does not fix loose tile or a failed shower pan. Know which problem you have before you buy a bag.
Recaulking is cheap and worth doing before water gets behind the tile. The job fails when the old caulk is still in the joint.
The fan is the easy part. The box holding it up is the part that decides DIY versus an electrician.
A straight swap of a standard outlet or GFCI is a common DIY. Scorched wires, aluminum, or a missing ground are not.
A straight wood fence on a flat lot is a hard weekend, not a mystery. The property line, the frost depth, and a pool change the project.
A deck attached to the house carries people and needs a real footing and ledger. A small shed kit is a different, smaller decision.
