Soft Washing Belfast

Soft washing is a specialist exterior cleaning technique that uses low-pressure water combined with professional biocide solutions to safely clean delicate surfaces that could be damaged by traditional pressure washing.

At Diamond Property Maintenance NI, we use soft washing for surfaces including roofs (tiles, slate, and flat roofs), rendered walls, K-rend and monocouche, UPVC fascias, soffits, and cladding, painted surfaces, wooden cladding and fencing, conservatory roofs, and delicate stonework.

Unlike high-pressure washing which can damage mortar joints, strip paint, and force water into gaps, soft washing relies on the cleaning power of professional-grade biocides. These solutions kill moss, algae, lichen, and organic growth at the root, providing longer-lasting results than pressure washing alone.

Our soft washing process begins with a thorough assessment of your property and surfaces. We then apply our professional biocide solution which gets to work killing organic growth. For immediate visual improvement, we can rinse the treated areas. The biocide continues working over the following weeks, with results lasting 3-5 years depending on conditions.

Soft washing is particularly effective in Northern Ireland's damp climate where moss and algae thrive. Regular soft washing protects your property from the damage that organic growth can cause, including moisture retention, frost damage, and surface deterioration.
