DOFF Chemical Cleaning in Newton Abbot
Stonehealth DOFF system — pressurised steam up to 150°C for listed and heritage stone. We work all over Newton Abbot and the surrounding Devon area — Wolborough, Highweek, Milber and the towns between.

The Moore & Franks approach in Newton Abbot
Sitting low in the Teign valley, Newton Abbot holds the damp — and the town's solid Victorian terraces and rendered post-war housing show it in green streaking and stubborn lichen on south-shaded walls. DOFF chemical cleaning handles that growth without the collateral damage a jet wash brings to older mortar joints. Superheated steam works right down into the surface — temperature rather than pressure — and a biocide top-coat where it's wanted keeps regrowth at bay for longer. Moore & Franks are a Devon family firm, twenty-five years in, insured to £5m public liability. Plain quote, tidy work, no upselling you something you don't need.
Below the wooded slopes at Decoy and Bradley, walls sit in shade and dry slowly for much of the year, and the rendered elevations through Wolborough and Highweek green and streak worst on their north faces. Low-pressure steam lifts that growth off render and masonry by heat, so soft post-war render and older stonework come up clean without the collateral a pressure jet brings to tired mortar joints.
The render estates climbing Mile End and Decoy are a newer problem for the town — silicone and monocouche finishes that streak black within a few seasons in this damp basin. Modern coatings like these often clean up best with a soft wash rather than full DOFF heat, and we'll recommend whichever suits the wall. Where steam is right, the heat lifts the algae without saturating a render system designed to shed water, not soak it up.
Nearer the centre, the older terraced stock around Courtenay Street and the station has tired pointing and painted render that won't take a pressure lance, set on tight streets where care matters. The steam's temperature does the cleaning, so soft old brickwork and rendered frontages come up clean without being knocked about, and we work methodically down each elevation rather than rushing a lance across the lot.
Our Newton Abbot customers are typically within 30 minutes of our Exeter base. We cover the wider TQ12 postcode area and the surrounding villages (Wolborough, Highweek, Milber, Kingsteignton, Decoy Country Park, Bradley Manor).
A clear, repeatable process.
No surprises, no upsells. The same method every job — that's how you get the same result every time.

Frequently asked questions
Quick answers to the questions we get asked the most. If yours isn't here, drop us a line — we reply same day.
Every DOFF job is priced on a free written quote after we've seen it, with no standard rate. In Newton Abbot the depth of growth is often the cost driver — years of valley-damp moss and lichen on a shaded north wall takes more steam time to clear fully than a surface that's only lightly greened.
Yes — Wolborough, Highweek, Milber and Buckland in town, plus Kingsteignton and out toward Decoy and the Bradley Manor side. Newton Abbot and the TQ12 postcode are around thirty minutes from our Topsham base, well within our regular patch.
Yes. The heat of the DOFF steam kills algae, moss and lichen right through rather than just skimming the surface, which matters on the long-shaded render the Teign valley produces here. A biocide top-coat afterwards can slow the regrowth where the aspect is particularly bad.
