In February 2025, we completed a full exterior clean of the Farmfoods supermarket at Plumer Road, Crownhill, Plymouth, PL6 5DZ. The scope included the corrugated metal roof, building sides/cladding, entrance canopy & frontage, plus sidewalks and surrounding hard surfaces.
This site had a corrugated roof with deep channels, which required significantly more time and detail work to lift embedded contamination and organic growth from the profiles. Access and safety were managed using a Mobile Elevated Work Platform (MEWP), allowing controlled, section-by-section cleaning with minimal disruption.
Public-facing entrance: work needed clear work zones and careful control around customer areas.
Our Approach (What we did, and why)
Access & safety setup MEWP positioned to reach roof edges, cladding, and entrance areas safely, with work zones managed at ground level.
Roof cleaning (corrugated metal) Targeted cleaning of the ridged profile and deep channels, removing organic growth and built-up grime with controlled pressure and consistent rinse-down.
Cladding/sides & facade washdown Systematic cleaning across elevations to remove weathering and staining and restore a uniform finish.
Entrance and storefront detailing Focus on high-visibility areas: entrance panels, canopy, glazing/frames and surrounding frontage, using pressure washing and extension-pole detailing where appropriate.
Sidewalks / hard surfaces Cleaning of pedestrian areas to lift staining and improve overall site presentation.
Results
Roof: visible reduction of moss/organic growth and restored appearance across the corrugated panels.
Cladding & walls: brighter, more consistent finish (clear before/after contrast on white sections).
Maintenance note: For retail sites, periodic exterior washing helps prevent long-term staining and keeps the building presentation consistent year-round.
