Soft Wash in Cullompton
Low-pressure biocide treatment for any exterior surface that can't take a jet wash. We work all over Cullompton and the surrounding Devon area — St Andrew's Church, Fore Street conservation area, The Walronds and the towns between.

The Moore & Franks approach in Cullompton
Cullompton's mix of old wool-town cottages, rendered terraces and the newer estates out toward the motorway all share the same problem: a damp Culm valley setting that grows algae and moss on render and painted walls year-round. The traditional cob and lime finishes around the centre are far too soft for a pressure washer, and even modern render suffers when it's blasted. Soft washing is the right tool: low pressure, a biocide matched to the surface, and growth killed at source rather than scrubbed off. We cover Cullompton easily from Exeter, give a fixed price before we start, and carry full public liability. Straight-dealing, careful, tidy.
The listed cob and lime render around Fore Street, St Andrew's and The Walronds is some of the most delicate work in Cullompton. This is protected, centuries-old fabric where harsh cleaning does genuine and lasting harm, and pressure washing is simply out of the question. Soft washing is built for exactly this: a low-pressure biocide matched to cob and lime, worked into the surface to kill the growth at root while leaving the historic wall breathing and completely undisturbed.
Out toward Honiton Road, Colebrook and the Knightswood estate, the housing is modern render on K-Rend and silicone systems, and it streaks and greens within a few years of being built. Sitting low in the Culm valley traps morning damp against these coated walls, so they discolour faster than owners expect. We lift the staining with a root-level treatment that leaves the coating sound, then suggest a repeat interval to keep the render clear rather than watching it green over again.
The prevailing south-westerlies push rain hard against exposed gables here, and the farmland wrapped around every edge of town throws pollen, dust and organic muck onto walls all season. Add the mature trees along the Culm shading north-facing frontages, and render gets grubby quickly. A low-pressure biocide treatment reaches the algae and grime in the surface and holds it back far longer than blasting, which only cleans the top and lets the growth creep straight back.
Our Cullompton customers are typically within 20 minutes of our Exeter base. We cover the wider EX15 postcode area and the surrounding villages (St Andrew's Church, Fore Street conservation area, The Walronds, Culm Valley, Knightswood estate, Colebrook).
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.
Each job is quoted after a free visit rather than from a fixed rate. Listed cob and lime work in the conservation area needs extra care and time compared with an open estate house, so the property type matters. We look first, then give you one written price with nothing added later.
The whole town and its edges, all of EX15. We soft wash from Fore Street and around St Andrew's out to the Knightswood and Colebrook estates and along Honiton Road. The outlying farms and cottages down the Culm valley lanes are all within easy reach from our Topsham base.
Yes, it is the only method we would use in the conservation area. Cob and lime render must breathe, and pressure forces water into walls that need to dry outward. A low-pressure biocide kills the growth on the surface without wetting the core, keeping protected Fore Street fabric both clean and sound.
Give us a ring or send a message and we will arrange to come and price the work, usually within a couple of days, with a same-day reply guaranteed. Once the written quote is agreed we fix a date. Weekdays, eight to five, and you deal with father and son direct.
