Immaculate Exteriors can easily wash away common surface grime from masonry surfaces with hot water or steam under pressure.

However, buildings in London can suffer from the more serious effects years of atmospheric pollution. Brick and stone can become stained black with carbon, either darkening the appearance of the entire building or creating unsightly and uneven patches on the façade. Water and detergent alone will not remove these stains.

As the degree of carbon staining varies greatly between
buildings we always view sites before providing a quotation.
A test area is sometimes necessary.

Immaculate Exteriors removes the unattractive effects of pollution by using specialist chemicals that dissolve the deposits. We apply the chemical, leave it for 5 minutes and then thoroughly rinse the surface with cold water. The process may need to be repeated two or three times on particularly blackened areas.

The effect of this process is dramatic. We are so used to seeing the effects of pollution in London that we forget that brick and stone can provide very attractive colour to our streets. Bringing these colours out from behind the grey really transforms the appearance of a property.

This process does not damage the brick or solid pointing,
as sand-blasting does.
