Moss Removal Eastbourne

A standard 3-bed semi in Eastbourne costs £300–£550 for a full soft-wash treatment and biocide application. Larger detached properties run £500–£900. We do not use pressure washing — it strips granules from tiles and voids material warranties. Soft wash and biocide is the only method we use, and the one recommended by tile manufacturers.

Two reasons: the coastal damp air and the town's established tree cover. Eastbourne's position on the Channel coast means sustained high humidity for much of the year — moss and lichen thrive in these conditions. Properties in Meads, Old Town and Hampden Park are worst affected due to the canopy cover of mature trees along these streets. North-facing roof slopes across the whole town are particularly vulnerable.

Both. Aesthetically it devalues the property — estate agents consistently report moss growth as a factor in survey reductions in Eastbourne. Structurally, moss retains moisture against tiles and mortar, accelerating decay. As root systems develop between tile overlaps, they physically lift tiles slightly — enough to allow wind-driven rain to penetrate on exposed coastal Eastbourne properties. Long-term it accelerates tile and mortar failure.

A correctly applied biocide treatment will kill existing moss and lichen and inhibit regrowth for 3–5 years in Eastbourne conditions. North-facing slopes with heavy tree cover may need retreatment at the 3-year mark. We apply a post-treatment biocide wash that continues working for months after application, breaking down dead material and washing it off naturally in rainfall.

A properly applied biocide soft wash treatment typically keeps moss and lichen at bay for 3–5 years on most Eastbourne properties. The Pevensey Levels properties in Westham and the wooded areas around Willingdon and Old Town tend towards the lower end of this range due to persistent ground humidity and tree canopy. We recommend scheduling re-treatment before visible regrowth returns.

No — we do not use pressure washing on roof tiles and we do not recommend it. High-pressure water strips the surface coating from concrete tiles, erodes the surface of clay and slate, and forces water into lap joints and under flashings. Our soft wash approach uses low-pressure application of a biodegradable biocide, which kills moss and lichen at the root without damaging the tile surface.

Moss removal treats the symptom of blocked valleys and gutters, and prevents future moss-related water ingress — but it will not repair existing damage. If your roof is actively leaking, the leak needs to be diagnosed and repaired first. We carry out a full roof condition check as part of any moss removal visit and will report any underlying repairs needed before treatment begins.
