Condensation and mould treatment

Black mould in corners, around windows and above the shower is a condensation problem. We treat the mould, fix the cause and stop it coming back.

Black mould spots growing in the top corner of a bedroom wall, a classic sign of condensation

What’s included

  • Mould cleaned and treated with a fungicidal wash
  • Cause identified, usually ventilation, insulation or heating
  • Cold walls insulated or lined where needed
  • Damaged plaster made good and skimmed
  • Anti-mould paint system advice
  • Practical steps to keep the room dry

Noticed mould, staining or peeling paint above the shower or around your bathroom windows? These areas are common problem spots because of moisture and condensation. Do not let a small problem become a bigger one.

What condensation looks like

Black speckled mould in the top corners of rooms, along the bottom of windows and behind furniture on outside walls. Streaming windows on cold mornings. A musty smell in a bedroom. Peeling paint on a bathroom ceiling. It is the most common form of damp in Teesside homes and the one most often misdiagnosed as rising damp.

What causes it

Warm, moist air from cooking, showering, drying clothes and simply breathing needs somewhere to go. Without enough ventilation it settles on the coldest surfaces in the house. Poor insulation makes those surfaces colder still, so the same room in the same house gets worse every winter.

How we treat it

  1. Treat the mould with a proper fungicidal wash, not bleach, so the spores are dealt with.
  2. Fix the cause. That might mean an extractor fan that actually works, trickle vents, insulating a cold wall or lining a ceiling.
  3. Repair the damage. Blown or stained plaster is made good and skimmed so you can decorate.
  4. Keep it away. We tell you what to change day to day, and which paint to use, so the room stays dry.

Landlords and tenants

Condensation and mould complaints are the ones landlords get most. We can survey, treat, repair and give you a written report of what was done, which is useful if a tenant or letting agent has raised it.

Questions we get asked

Why does mould keep coming back after I clean it?

Because cleaning removes the mould, not the moisture that grows it. Warm, damp air hits a cold wall or window reveal, condenses and mould follows. Until the ventilation or the cold surface is dealt with it will return.

Is black mould dangerous?

It can affect breathing, especially for children, older people and anyone with asthma. It is worth taking seriously rather than painting over. We treat it properly and deal with what is causing it.

Will insulation help?

Often, yes. Poor insulation leaves walls and surfaces cold, which is where condensation forms. Lining a cold external wall or insulating a bathroom ceiling removes the cold surface the mould needs.

Do you do bathrooms?

Bathrooms and kitchens are where we see most condensation damage: staining and peeling paint above the shower, around the window and on the ceiling. We repair the plaster and advise on extraction so it stays fixed.
