Softwashing & Biocide Treatment · Hertfordshire

Softwash roof treatment across Stevenage — Hertfordshire

Stevenage is about 5 miles from Hitchin, and we cover it alongside Knebworth, Hitchin and Walkern. We are based in Ampthill, roughly 20 road miles away, which keeps softwashing and biocide treatment bookings here practical to schedule.

The neighbourhood layout put dense shelter-belt planting between estates, so back gardens are shaded and mature — and the original tiles are now old enough that surface porosity holds moss firmly.

What Stevenage customers usually call about

The recurring issues we are asked to deal with in Stevenage are green algae film returning within months of a clean, black streaking down light-coloured tiles, lichen spotting across the whole pitch and render and cladding greening on the shaded elevation.

The neighbourhood layout put dense shelter-belt planting between estates, so back gardens are shaded and mature — and the original tiles are now old enough that surface porosity holds moss firmly. That mix determines the kind of enquiry we get — and it is why we quote on the actual property rather than a per-square-metre rate.

Working in SG1 and SG2

Water for softwashing and biocide treatment comes from an outside tap where there is one; if there is not, tell us and we bring our own supply to Stevenage.

We work Stevenage alongside Knebworth, Hitchin and Walkern, so if a neighbour wants the same softwashing and biocide treatment done we can usually fit both into one visit.

What softwashing and biocide treatment actually involves

Low-pressure softwash and biocide treatment that keeps roofs cleaner for longer.

Softwashing applies the cleaning solution at low pressure and lets the chemistry do the work, rather than relying on force.
Biocide kills the algae, lichen and spore load left behind after physical cleaning, which is what actually slows the return of green staining.
Low pressure throughout — nothing is blasted.

Which parts of Stevenage we know best

We plan softwashing and biocide treatment runs so that Old Town and Shephall and the outlying lanes are covered on the same day where possible.

We have worked enough Stevenage streets to know which roofs carry green algae film returning within months of a clean before we get the ladder off the van.

Booking rhythm in SG1

Dry spells matter more than warm ones for softwashing and biocide treatment: we would rather move a Stevenage date by a week than work a soaked roof.

Roofs on the Old Town, Shephall and Bedwell side of Stevenage tend to need softwashing and biocide treatment sooner than the more exposed newer estates, simply because of shade and leaf fall.

Stevenage and the surrounding villages

Stevenage sits roughly 5 miles from Hitchin and about 8 miles from Letchworth Garden City, so these all fall on the same softwashing and biocide treatment runs:

Knebworth
Hitchin
Walkern
Aston
Graveley
Shephall

Questions we get asked

Does the softwashing and biocide treatment method change by covering type?

Yes. Light-coloured interlocking tiles: show algae first and benefit most from routine biocide treatment. We identify the covering before quoting anything in Stevenage.

What do commercial owners and site managers in Stevenage usually ask you for?

Mostly safe access planning, out-of-hours options and a written record of what was done. Commercial sites usually need the visit planned around opening hours — say so when you enquire and we will work to it.

Can you work outside business hours on commercial premises?

Often, yes. It depends on safe daylight working and access, but early starts and weekend visits are both possible on commercial sites.

Will you tell me if softwashing and biocide treatment is not needed yet?

Yes, and we do it regularly in Stevenage. If the honest answer is to leave it another season, that is what you will be told.

How is softwashing different from pressure washing?

Softwashing uses low pressure and a cleaning solution. Pressure washing uses force. On roofs, force is what causes the damage, which is why we do not use it.
