Commercial Exterior Cleaning for Construction and Development Projects

Project phase and sequencing

Exterior cleaning may be needed before practical completion, during a phased handover or after surrounding trades have finished. The best timing depends on trade completion, weather exposure, access, surface condition and the risk of renewed soiling, and it is agreed in the programme so cleaned areas are less likely to be affected by ongoing work.

Access and site logistics

Scaffolding, hoarding, plant, deliveries and incomplete external works may limit access to particular elevations or hard surfaces. These constraints are recorded at the survey and built into the specification of works and programme.

Plots and priorities

A single completed building or final project stage may need one visit. On a larger development, a show home, main entrance or first handover plot may need attention before later phases, and the work can follow sectional completion, marketing activity or a rolling handover programme. Prominent elevations, entrances, approaches and rooflines can come first, so agreed external areas are ready for the next inspection or occupation stage. The specification of works sets the order, so the project team can prioritise without applying one date to the entire development.

Construction residue

We identify each mark and the surface it sits on at the survey, and separate cleanable residue from defects or damage that need another trade. The approach depends on the residue, substrate, age and condition. Where complete removal cannot be guaranteed, this is identified before works begin and the expected improvement is set out clearly.

The work covers external building surfaces and suitable surrounding hard areas on new-build housing developments; office, retail, industrial and mixed-use developments; and refurbishments and conversions, where existing and newly installed materials sit side by side. It complements the wider builders' clean without replacing internal cleaning or specialist remedial works. The specification of works is set by the development, the surface condition, the residue, access and the handover priorities, and can deal with one focused issue or bring several services together.

Roofs

We identify the roof covering before any work is proposed and request the asbestos register. Asbestos-cement and fragile roofs are never pressure-washed or walked on.

Wash water

We plan wash-water control and drain protection for every site.

Listed and conservation buildings

We use test areas and low-pressure methods on listed and conservation-area buildings.
