DOFF Chemical Cleaning in Plymouth

The Moore & Franks approach in Plymouth

Plymouth's exposed coastal position and big stock of rendered post-war and limestone-built housing make for a lot of green walls — the wind off the Sound carries damp deep into the city, and shaded frontages stay algae-marked year-round. DOFF chemical cleaning clears it with superheated steam at low pressure, sparing soft render and old mortar the damage a jet wash would do. The heat kills to the root, and a biocide top-coat where it suits keeps the wall clean longer. Moore & Franks travel west from Exeter for Plymouth work — a family firm, twenty-five years on, insured to £5m. Fair pricing and a properly clean, lasting finish.

The Edwardian villas along the tree-lined avenues of Mannamead and Mutley, and the rendered stock across Peverell and Hartley, sit shaded enough that their walls stay damp for weeks at a time. That's ideal ground for the green moss and black algae that coat render and masonry here. Steam lifts it off the wall by heat at low pressure, clearing years of growth from soft render and old stone without the scarring a pressure jet risks on tired city fabric.

The Barbican and Stoke hold the city's oldest limestone and render, wearing decades of soot on top of the usual coastal growth. Soft limestone and lime render like this can't take pressure without harm. Temperature-led steam lifts the soot, algae and crust off historic masonry while the heat, not force, does the work, and on genuinely delicate heritage fabric we agree a discreet test patch before treating a full elevation.

Out at Sherford and Saltram Meadow the render is new but already marking, sealed coatings picking up streaks early in the maritime damp, and surfaces like these often suit a soft wash better than full DOFF heat — we'll advise which we'd use. On the most exposed, salt-driven elevations across the city, an optional biocide top-coat after cleaning slows how quickly the green returns, though we only suggest it where the aspect earns it.
