DOFF Chemical Cleaning in Honiton
Stonehealth DOFF system — pressurised steam up to 150°C for listed and heritage stone. We work all over Honiton and the surrounding Devon area — Honiton High Street, St Michael's Church, Heathpark and the towns between.

The Moore & Franks approach in Honiton
Honiton's long Georgian high street and the rendered and rough-stone homes around it sit on heavy East Devon clay, and that damp ground keeps masonry greening through the cooler months. DOFF chemical cleaning suits the older town stock — superheated steam at low pressure that clears algae, lichen and moss without the surface damage pressure washing brings to period frontages. The temperature works to the root so the clean actually lasts, and old fabric is dry again within minutes. Moore & Franks are a Devon family firm with twenty-five years behind them and £5m public liability cover. Fair quote, careful hands, and a straight answer on what your walls need.
Out in the lanes toward Gittisham and Combe Raleigh, the farmhouses and barn conversions often carry large roof spans on exposed ground, and the cob and lime render below needs breathable, gentle cleaning rather than anything aggressive. These are properties where a careless wash does lasting harm. Low-pressure steam clears the moss and algae off the render by heat, and on big rural properties we plan access and water before the day so the job runs without fuss.
The 1990s and modern brick semis around Heathpark and off Hayne Lane are a different proposition from the old town core. Brick and modern render greened by the damp clay air can often be cleaned with a soft wash as readily as with full DOFF heat, and we'll advise which we'd choose. Where steam is the right call, the temperature lifts the algae film without forcing water into pointing or behind a modern coating.
Off the high street along New Street and Silver Street, Victorian terraces stand shoulder to shoulder with far older cob and thatch, under mature trees that shed straight onto them every autumn. Thatch and soft render close together call for real care, and we keep steam well away from anything it shouldn't touch. Cleaned properly by heat rather than pressure, these period frontages come up without the surface being disturbed.

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.
DOFF work is quoted free after a look, with no set price list. In Honiton the size of the frontage is often the cost factor — the large farmhouse and barn-conversion elevations out toward Gittisham take considerably more steam time than a terraced wall off the high street.
The town and the outlying lanes — the high street and St Michael's Church, New Street and Silver Street, Heathpark, and out toward Gittisham, Combe Raleigh and Dumpdon Hill. Honiton and the EX14 postcode are around twenty-five minutes from our Topsham base.
Yes. Because it works by temperature at low pressure, DOFF lifts moss and algae from soft cob and lime-rendered walls without scouring them or driving damp inside. Near thatch and other delicate detail we work carefully and agree a test patch first on anything fragile.
