Our shop is near Bupyeong Station. They came after closing time, so the next day's business wasn't affected at all.

Worried about calling someone in Korea? Here's the honest answer.
"Will I be charged more because I'm a foreigner?"
The price comes from the fixture and the blockage, not from who you are. Send a photo and you get the same price range anyone else would get — in writing, before we come. The final amount is agreed with you on site before any work starts.
"The technician won't speak English. How will I know what's happening?"
Chat support is fully in English, 24 hours a day. On site, the technician keeps using that same KakaoTalk or WhatsApp chat with live translation to show you what they found and confirm the price. You will not be left guessing.
"Will they only take cash?"
No. Card, cash and bank transfer are all fine, and we can issue a cash receipt or tax invoice. You pay after the work is done and checked together.
"Is it more expensive at 2am?"
No. There is no night, weekend or public-holiday surcharge. The price is the same 24 hours a day, every day.

"I can't write my address in Korean."
You don't need to. Send a map pin, or a photo of your building entrance and the address label — that is enough for us to find you.
"Will they start breaking open walls?"
Not without telling you. We diagnose first — camera inspection for drains, thermal and acoustic detection for leaks — precisely so that we know where the problem is before anything is opened.
"Who am I letting into my home?"
A registered business, not a call centre. Our business registration number, representative and office address are at the bottom of this page, and you can read our reviews on Google Maps.
"What if it doesn't work?"
No fix, no charge. If we cannot resolve it, you pay nothing — and completed work carries a 1-year free warranty.
Not sure if it's your problem or the building's?
A slow drain can have three completely different causes: your own trap, your unit's branch line, or the building's shared stack. Someone pays a different bill in each case — and you cannot tell them apart by looking. Anyone who says on the phone which one it is, without seeing inside the pipe, is guessing.
- We put a camera in the pipe and look at the blockage with you, so the cause is confirmed, not assumed.
- Send a photo first and we give you a price range before anyone is dispatched. If we cannot fix it, you pay nothing.
- If it turns out to be the building's shared pipe, we tell you — and give you a written report in English and Korean, with photos and camera footage, so you can hand it to your landlord or building management instead of paying for someone else's pipe.
Finding out what it actually is costs you nothing to ask.
Renting? We'll help you sort out who pays
In Korea, whether a blockage is the tenant's cost or the landlord's often depends on where in the pipe the problem is — and that is exactly what our camera inspection shows.
- We tell you on site whether it looks like a tenant issue or a landlord / building issue.
- We can issue a written work report in both English and Korean, with photos and camera footage, that you can forward straight to your landlord, agent or building management.
- Just ask for it on KakaoTalk or WhatsApp before we arrive, and we'll prepare it.

Waiting makes it more expensive
Caught early, a slow bathroom drain is usually 55,000–80,000 KRW. Left until several drains back up at once, the same pipe becomes a main-line job at 150,000–400,000 KRW. The blockage does not clear itself — it narrows the pipe a little more every week.
Sending a photo costs nothing and takes ten seconds.
No surprises on the bill
- Credit / debit card, cash and bank transfer all accepted
- Cash receipt and tax invoice issued on request
- No night, weekend or public-holiday surcharge — the same price 24/7

Drain, toilet and sink clogs explained
Clogged drain (bathroom, balcony, floor drain)
A drain that empties slowly is usually a trap full of hair and soap scum. When several drains in the home slow down at the same time, the blockage is deeper — in the branch or main line — and needs a camera inspection.
Typical price: 55,000 – 400,000 KRW (≈ US$40–290)
Causes, what to try first, and how we fix it
Common causes
- · Hair and soap scum in the trap
- · Grease and sludge coating the pipe wall
- · Shared vertical stack blocked (apartments)
- · Dry trap causing sewer smell
Try this first
- · Remove the strainer and pull out visible hair
- · Flush with hot (not boiling) water
- · Pour water into unused floor drains weekly
- · Avoid repeated chemical drain cleaner
How we fix it
- · Trap dismantled and washed
- · Motorised spring auger through the branch line
- · 150 bar high-pressure jetting
- · Endoscope camera check before and after
Clogged toilet
Most Korean toilets block in the trapway right behind the bowl. Wet wipes are the number one cause — they do not break down. If the water level rises after a flush, stop flushing and close the valve behind the toilet.
Typical price: 55,000 – 300,000 KRW (≈ US$40–210)
Causes, what to try first, and how we fix it
Common causes
- · Wet wipes and paper towels
- · Objects dropped in: phones, toys, brushes
- · Too much toilet paper at once
- · Blocked soil stack causing sewage backflow
Try this first
- · Flush only once, then stop
- · Close the angle valve behind the toilet
- · Use a flange plunger with a full seal
- · Do not pour boiling water — ceramic can crack
How we fix it
- · Closet auger through the trapway
- · Wet vacuum for water and debris
- · Toilet lifted and refitted for object retrieval
- · Soil stack jetting if sewage is backing up
Clogged kitchen sink
Kitchen lines block from cooking oil that cools and hardens on the pipe wall, then traps food waste. A sink that gurgles or backs up when the neighbour drains water usually points to the shared kitchen line.
Typical price: 55,000 – 250,000 KRW (≈ US$40–180)
Causes, what to try first, and how we fix it
Common causes
- · Cooking oil hardening inside the pipe
- · Food waste past the strainer
- · Corrugated hose sagging under the sink
- · Shared kitchen stack blocked
Try this first
- · Wipe oily pans with paper before washing
- · Keep the mesh strainer in place
- · Run hot water and detergent after cooking
- · Check the hose under the sink is not kinked
How we fix it
- · Trap and hose dismantled and degreased
- · Spring auger through the branch line
- · 150 bar jetting for hardened grease
- · Leaking connectors replaced on the spot
