๐ What actually happened
Tried to replace a faucet washer, ended up dismantling the whole faucet. Reassembled it wrong, leaking into the in-wall pipe. Ended up tearing the wall and replacing the pipe — first repair ₩30k → final ₩900k.
Replaced an outlet themselves, caused a short → breaker damage. A ₩20k outlet became ₩150k for breaker replacement + electrical inspection.
Did wallpaper themselves, crooked from the first sheet. Peeled and re-stuck until the paper tore. New wallpaper + pro re-work — double the cost.
In contrast, the pro case: called for a faucet washer swap → partner visit 15 min → done, ₩28k. "I should have just called right away."
A job a pro finishes in 15 minutes,
we ruin in 4 hours.
It's not a difference of talent.
It's the difference between someone who's done it 500 times and someone doing it for the first time.

② 3 real reasons a pro is cheaper
500 times of experience
What you're doing for the first time, he's done 500 times. The failure odds are fundamentally different.
Failure rate <1%
Tools already owned
He already owns pro tools. You don't need to buy any. Tool costs often exceed the labor fee.
Reusable forever
Speed = cost
Your 4 hours = his 20 minutes. Even at ₩10k/hr, 4 hours is ₩40k. You already lose.

④ Ask these 3 questions before starting DIY
QUESTION 01
How bad is the loss if it fails?
A failed bulb swap = ₩5,000 bulb. A failed pipe repair = up to ₩1M. If the failure cost exceeds the pro's fee, calling a pro from the start is rational.
๐ก If failure cost > pro cost → call a pro right away
What is your time worth?
Someone earning ₩10k/hr spending 4 hours = ₩40k already. If the pro's fee is ₩30k, DIY is more expensive. Count the value of your weekend and free time too.
๐จ If your time + tool cost > labor fee → the pro is cheaper
Is there a safety issue?
Electricity, gas, and height work must not be DIY. There's danger to life, unlicensed work is illegal, and insurance won't cover a fire.
๐ Electricity·gas·height work → always a pro. No exceptions
