Soft wash biocide treatment — no high-pressure washing. Covering all SO50 postcodes. Free quotes.
Tell us the job in 30 seconds. No pushy sales, no call-out fee.
Eastleigh's tree-lined Victorian streets around Campbell Road and Leigh Road, combined with the Itchen valley humidity from Bishopstoke, create consistent moss growth on north-facing slopes. The older properties near Eastleigh Station see faster regrowth than the 1980s estates further out. We carry out soft wash biocide treatment across all of SO50 — moss killed at the root, not pressure-blasted off. Valley clearing is the most time-critical moss job in Eastleigh: the established tree canopy along the older roads fills valleys quickly every autumn.

Request Free QuoteMoss thrives in persistent moisture. In Itchen valley humidity from Bishopstoke, north-facing slopes and valley areas remain damp for extended periods — ideal conditions for rapid moss establishment. The Victorian terraces near Eastleigh Station and 1950s to 1980s semis in Bishopstoke and Fair Oak means that Welsh slate on Victorian stock, concrete interlocking on post-war estates roofs are the primary substrate across Eastleigh. Concrete interlocking tile is more susceptible to surface moss growth than clay or slate — the surface texture retains moisture better and provides better anchorage for moss roots.
We use soft wash biocide application — low-pressure delivery of moss-killing solution that kills growth at the root without the surface damage that high-pressure washing causes. On concrete tile roofs across Eastleigh, high-pressure washing strips the tile surface and erodes pointing. Dead moss weathers away over 3 to 6 months after treatment, leaving a biocide residue that suppresses regrowth for 2 to 4 years in Itchen valley humidity from Bishopstoke.
Valley blockage is the most urgent moss-related issue in Eastleigh. Debris accumulating in valleys — moss growth, leaf fall, lichen material — blocks the drainage channel and causes water to back up under the tile covering. In Itchen valley humidity from Bishopstoke, a blocked valley in October typically causes a visible damp patch before Christmas. We carry out valley clearing as a standalone service or as part of a full roof treatment, with inspection of tile condition included.

In Eastleigh, moss is a constant rather than a one-off — the question is whether yours is cosmetic or is starting to hold water and block the gutters.
When it is not the answer: A light dusting of moss on a sound roof is cosmetic and can be left; we never pressure-wash a tiled Southampton roof, which drives water under the laps and strips the tile surface Read the full guide.
We come out, go up on the roof and into the loft, and trace the fault to its real cause on your Eastleigh property before quoting a penny.
Your quote is itemised and plain — access and scaffold priced as separate lines — so you can see exactly what you are paying for. No obligation.
We agree a time that suits you, and we attend the same day for genuine Eastleigh emergencies.
We hand-scrape and soft-brush the moss (never pressure-wash tiles), clear it from the gutters and valleys, and apply a biocide to slow regrowth.
Everything is cleared away, we walk you through the finished job, and you get the written guarantee.
| Job | Typical duration |
|---|---|
| Moss removal + biocide — semi | 1 day |
| Full clean — detached | 1–2 days |
| Gutter clear add-on | 1–2 hours |
| Biocide-only re-treatment | Half a day |
Wet or high-wind days pause work at height safely — we build weather margin into every Eastleigh booking.
Moss work runs from towers, roof ladders or scaffold depending on pitch and height, always itemised in the quote. Scaffold is specified for: steep or high roofs where safe standing time is needed for the full slope - always itemised in your written quote, never a hidden extra, and we arrange it.
Eastleigh’s railway-era terraces around the town centre have tight rear access, so scaffold and skip permits go through Eastleigh Borough Council. Pavement scaffold and skip permits go through Eastleigh Borough Council; allow a few working days on streets like Leigh Road, Market Street, the streets around Eastleigh station where space is tight.

The removal work is guaranteed; biocide slows regrowth for a season or two, though moss returns naturally on shaded Southampton roofs.
The workmanship is guaranteed for 10 years in writing across Eastleigh, with manufacturer material warranties on top of that.
“NFRC maintenance guidance identifies blocked rainwater goods as a leading avoidable cause of water ingress and fascia decay, recommending clearing before winter as basic preventive roof care.”— NFRC maintenance guidance / HSE work-at-height
Quiet, external work — some scraping noise and bagged moss removed at the end — with no need to be home. You do not need to stay home for external work - we just need power and access agreed in advance.
Removal runs year-round; biocide is applied in a dry window so it is not washed off before it works. Eastleigh sits inland of Southampton Water with slightly less salt exposure but the same south-westerly rain-bearing winds.
