The Moore & Franks approach in Cullompton
Cullompton sits in the Culm valley, and that's the heart of the problem for render here — low-lying, damp, and prone to morning mist that keeps walls wet for hours. The old wool-town render along Fore Street and the big newer estates out by the motorway junction both green up on their north sides. Damp inland air breeds algae just as readily as coastal salt, and a pressure washer only drives the moisture deeper. Moore & Franks soft-wash render properly: low pressure, the right biocide, no harm to the coating. Family-run, fully insured to £5m, and a straight run down the M5 from our Exeter yard.
Cullompton's newer render estates — Knightswood, Colebrook and the growing edges off Honiton Road — are where render greens fastest here. They went up on K-Rend and silicone systems that streak within a few years, and sitting low in the Culm valley they get little of the drying wind that keeps growth down. We clear these at low pressure and treat them, so the colour comes back without the thin coating taking any damage from a lance.
The historic heart around Fore Street and St Andrew's is another matter — cob, lime render and old clay tile, much of it listed or inside the conservation area, with buildings like The Walronds needing real care. Harsh cleaning damages this fabric outright. We use a gentle, breathable biocide at minimal pressure, lifting the ingrained green growth without sealing walls that have stood for centuries and must be left to breathe.
With farmland on every edge, Cullompton render collects more than algae — pollen, field dust and organic muck all settle into it, and the south-westerlies drive rain hard against exposed gables. Mature trees along the Culm shade the north-facing walls and slow their drying further. A soft-wash resets it, and the biocide carries on working on regrowth for months, though we are honest that a wall this close to open fields will grub up again quicker than a town-centre one.
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).

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.
Cullompton render is quoted per job. A modern semi on the Knightswood estate is quick; a large or listed property around Fore Street needs slower, gentler work and takes longer. Wall area, height and access set the figure, and the survey and quote are free.
Yes — Fore Street and the conservation core, out to Knightswood, Colebrook and the estates off Honiton Road. We cover the EX15 postcode and its edges, a 20-minute run up the M5 from Topsham.
No — that's exactly why we use it. The cob and lime render on Cullompton's listed buildings must breathe, so a low-pressure biocide clears the growth without sealing or scarring the fabric. Pressure or coatings would cause real, lasting damage.
Message us and you'll get a same-day reply. Quotes and cleans run weekdays, eight until five, and the visit is free. With the M5 junction on the doorstep, Cullompton is a quick 20 minutes from us.
