Attic Cleaning & Mould Removal in South Dublin

From Rathfarnham and Terenure to Dundrum, Blackrock and Dalkey, BioClean cleans attics, treats mould and looks after roofs for homes across South Dublin and Dún Laoghaire-Rathdown.

Homes in South Dublin and what we find in their attics

South Dublin is full of solid, well-kept family homes, many of them built between the 1930s and the 1980s. Rathfarnham, Terenure, Templeogue, Churchtown and Stillorgan are home to thousands of semi-detached houses, while Blackrock, Monkstown, Dalkey and Killiney have older Victorian and Edwardian properties alongside newer developments in Sandyford, Leopardstown and Stepaside.

Over the years a lot of these houses have been extended, with rear kitchen extensions, attic conversions and dormer windows. Each change alters how air moves through the roof. A conversion can leave small, unventilated voids behind the walls, and new insulation is sometimes pushed tight into the eaves where air used to flow. These hidden corners are where condensation and mould usually start.

Homes near the coast from Booterstown to Killiney deal with damp sea air, while houses in the foothills around Ballinteer, Knocklyon and Kilternan get more rain and colder nights. In both cases, a roof space that cannot breathe will show it sooner or later.

The problems we see most often

• Attics that need clearing before a sale, a conversion or new insulation. See attic cleaning.
• Mould in attic voids and eaves after extensions or conversions. See attic mould treatment and roof vents.
• Mould on walls and ceilings in bedrooms and bathrooms. See mould removal and anti-mould paint.
• Green, dirty conservatory roofs on rear extensions. See conservatory roof cleaning.
• Moss on roofs and full gutters under mature trees. See roof cleaning and gutter cleaning.

What we do

Attic and mould work is our speciality, but we look after the whole house, from the roof space down to the gutters.

How it works

South Dublin questions

Do you cover Dún Laoghaire-Rathdown as well as South Dublin County?

Yes. We work across both council areas, from Rathfarnham and Templeogue to Dún Laoghaire, Dalkey, Killiney and Shankill.

We have an attic conversion. Can you still help?

Yes. Converted attics often have small storage voids and eaves spaces behind the walls, and those are exactly the places where mould and dust collect. Tell us about the layout when you get in touch.
