The façade, or the face of a building, plays a major part in the appearance & visual impact of a building.

The associated stonework can require comprehensive treatment; ranging from a sensitive cleaning process to full restoration and masonry works.


Brick and Stonework cleaning must be carried out with great care, as the masonry can be irreversibly damaged by inadequate repairs, replacement, re-pointing or cleaning. A careful cleaning process will enhance the appearance of Brick and Stonework a great deal, preserving the appearance and character of the building.

During our cleaning process, we treat all freshly cleaned brick and stonework with a clear masonry water repellent sealer. This allows the fabric of the building to breath and will also reduce the effect of further pollution hazards.

Our cleaning services are by no means limited to outer surfaces, with many of our clients contracting us to undertake projects on internal stonework, particularly in the restoration of older buildings. Our state of the art Rotec system allows us to undertake a low pressure, gentle rotary whirl jet cleaning of sensitive surfaces.

There are many different types of soiling that can affect brick and stonework: vegetation such as moss or algae, stains from corroded metal, chemical deposits and graffiti to name but a few.

Vegetation can grow on the surface of any damp masonry. Organic growths can be removed by applying a biocide; although they will usually die off naturally if the moisture source is eliminated.

Metal stains from corroding steelwork can be particularly difficult to remove successfully, due to the oxidisation created during the rust process.

Graffiti removal generally requires the use of solvent paint removers, and often combined with the use of a gentle abrasive cleaning.

Chemical deposits such as calcium sulphate or black gypsum crusts occur through atmospheric pollution. It is visually unattractive and in extreme cases can lead to a deterioration of the masonry itself.

McGuinness Building Preservation Ltd has decades of experience in the cleaning and restoration of façades and masonry work.

Restoration & Repair

The restoration of Brick and Stonework can range from re-pointing to the replacement of affected masonry using materials that are compatible and compliment the original fabric of the building.

Re-pointing should only be carried out when the existing pointing has failed and where water penetration is taking place. It is vital that the correct style of pointing is used along with the appropriate materials. The use of inappropriate joint finishes or mortars can seriously alter the appearance of a historic building, detract from its original character, and can result in accelerated decay of the stone over time.
