Window Cleaning Belfast

Diamond Property Maintenance NI delivers professional window cleaning across Belfast and Northern Ireland for homes, offices, storefronts, schools and industrial units. We use a pure water, deionised system that leaves glass streak free and spot free without smears, detergent film or hard water marks.

How does pure water window cleaning work? The system filters all minerals out of the water so it dries clear with nothing left behind on the glass. We apply it through water-fed poles, which reach upper-floor windows safely from the ground with no ladders leaning against your walls or gutters. That means high windows, awkward stairwells and second-storey panes get cleaned properly rather than skipped.

Every clean includes the frames and sills, not just the glass. Dirt collects in the frame corners and runs back down onto clean glass if it is left, so we wash the whole unit each visit. For commercial clients we cover shopfronts, glazed entrances, office blocks, schools and factory glazing, and we can work around your opening hours.

Northern Ireland weather throws rain, salt air and grime at your glass all year, so windows dull faster here than in drier regions. A regular schedule keeps them consistently clear rather than letting build-up set in.

We offer one-off cleans and regular contracts on a weekly, fortnightly or monthly cycle. Residential visits typically run from £20 to £50 depending on the size and number of windows. Every job is covered by our £10M public liability insurance, and our team brings over 30 years of property maintenance experience to each visit.
