DOFF Chemical Cleaning in Topsham

The Moore & Franks approach in Topsham

Topsham's Dutch-gabled merchant houses and listed riverside frontages are exactly the sort of fabric that punishes a careless wash — old brick, lime pointing and painted render don't take kindly to high pressure. DOFF chemical cleaning is the careful route: superheated steam at low pressure that lifts algae, lichen and moss while leaving historic surfaces undisturbed. Our yard is on Ferryman Way in Topsham, so this is our doorstep and we know the conservation stock well. Twenty-five years on the tools, fully insured to £5m, and a real respect for older buildings. We'll tell you straight if DOFF is right for your property — or if it isn't.

Along the Exeter Road and the Riverside estates, silicone and monocouche render that's barely ten years old is often already carrying a visible film of estuary grime. These sealed coatings often want a gentler soft wash rather than full steam heat, and we'll say so up front. Where DOFF is the right tool, the heat clears the greening without pushing water behind a render system that relies on staying watertight to do its job.

The period terraces and brick frontages around The Strand, Fore Street and the Quay take the brunt of the salt-laden mist rolling off the tidal Exe, and black algae, green growth and the rust-red gloeocapsa bloom all dig in on walls that rarely get a drying wind. Steam, working by heat rather than force, lifts that growth off brick, pointing and painted render without the surface damage a pressure jet would leave on aged, mist-facing fabric.

Being based a few streets away on the estuary side of town, we know how tight some of the lanes and back gutters around Fore Street and the Quay can be, and we plan access accordingly. After a clean, an optional biocide top-coat can be worth it on the shaded, mist-facing elevations that green back quickest, though on many Topsham frontages a simple steam clean at a sensible interval keeps things in hand.
