Mold Removal in Gangnam & Seocho

English-friendly mold removal. We find the cause, remove mold down to the wall and stop it coming back. Free on-site inspection.

Gangnam-gu and Seocho-gu mix older apartment complexes from the 1980s and 1990s with new high-rises and officetels. Expat families often rent in Banpo, Seorae Village, Daechi and Samseong, and professionals live in officetels around Yeoksam and Gangnam Station.

The mold we see here is mostly condensation: older complexes with aging window frames and thin insulation, and new airtight buildings where moisture has nowhere to go.

Where mold shows up in Gangnam homes

Window walls in older complexes

Aging frames and cold concrete around the window collect condensation every winter. The wallpaper under the window turns grey first.

Ceilings and top corners

Top-floor and corner units lose heat through the ceiling. Moisture condenses in the corner where wall meets ceiling, usually above a bed or desk.

Officetel bathrooms and closets

Small officetels with a single window and an enclosed bathroom trap humidity. Mold appears on silicone, closet backs and behind the shoe cabinet.

Why it keeps coming back

In older complexes the problem is cold walls; in new towers and officetels it is moisture that cannot escape. Both lead to condensation behind the wallpaper. We treat the wall and, where needed, add insulation so the surface stays warm enough not to sweat.

How we treat it

1. Removal

Strip mold-infested wallpaper and damaged material down to the wall.

2. Sterilization

Treat the wall to kill spores and roots deep in the surface.

3. Anti-mold coating

Seal the surface against moisture so mold cannot settle again.

4. Insulation & finish

Insulate cold walls where needed, then finish with diatomite or wallpaper.

Questions from Gangnam residents

I'm in an officetel with very little ventilation. Will treatment help?

Yes, combined with a few habit changes. We remove and treat the mold, then show you where moisture builds up so it doesn't return.

Can you work while we're still living in the apartment?

Usually yes. We protect furniture and floors, and plan the work room by room.

The mold is on the ceiling. Is that a leak?

Not always. Ceiling corners on top floors often have condensation, not leaks. We check the pattern and moisture before deciding.
