Mold is extremely common in Korean housing — you’re not alone

Mold Removal Cleaning — Bathrooms, Walls & Wallpaper

Home cleaningMove-out cleaningMove-in cleaning

Black spots in the bathroom? A damp smell in the closet? Mold along the window frames? Korea’s humidity makes this very common, especially in officetels, one-rooms, and semi-basement homes. We remove it — and explain how to stop it coming back.

Mold & Korean Housing

Why Korean homes get so much mold. Humid summers and the monsoon (장마) season, compact units with little airflow, condensation where warm indoor air meets cold exterior walls, and semi-basement (반지하) housing all feed mold growth — most often in bathrooms, closets, behind furniture, and along window frames. Many foreigners are surprised by it; it’s normal here, and it’s treatable. Homes, companies, property managers, and multi-unit buildings are all welcome. Night, dawn, and weekend visits are charged at the same rate. A tax invoice (세금계산서) is available, and we work discreetly so your neighbors won’t know.

Who this is for

Residents finding black mold in the bathroom or on silicone seals, mold on wallpaper or closet walls, a musty/damp smell that won’t go away, or condensation problems in an officetel, one-room, villa, apartment, or semi-basement.

How We Treat Mold

Our cleaning approach:

  • Remove visible mold from tiles, silicone, walls & frames
  • High-temperature steam on affected surfaces
  • Food-safety approved cleaning agents
  • HEPA vacuum to capture loosened spores
  • Odor neutralization for the damp/musty smell
  • Practical advice on ventilation & moisture control

How It Works

⚠️ Important & honest: mold is caused by moisture. Cleaning removes the mold that’s there now, but if the source — a leak, condensation, or poor ventilation — isn’t addressed, it can grow back. We’ll identify the likely cause and tell you what to change. If wallpaper or drywall is soaked or rotted, that section is usually replaced by an interior contractor rather than cleaned, and we’ll let you know clearly. We do not use ozone or apply any coating — our work is thorough cleaning and treatment.
