Soft Wash Treatment

Gentle on Surfaces. Tough on Growth.

Soft washing refers to the use of specialist cleaning treatments applied at low pressure, rather than relying on high-pressure cleaning. It is suitable for a wide range of exterior surfaces affected by algae, moss, lichen and other organic growth.

What the job involves

Preparation, Application, Rinse

Planting, lawns, glass and paintwork are covered or wetted down, the solution is applied evenly at low pressure, it is given the time it needs to work, and then the surface is rinsed down.

Most of the time on site goes into the preparation and the rinse rather than into the application, and we build that into the job.

How we work

Our working principle

Use the lowest possible pressure and the least amount of chemical necessary to achieve the right result. This may sometimes require additional applications or a more considered process, but we believe that is always preferable to taking the quickest or most aggressive approach. Our priority is to achieve the best possible result while protecting the surface and surrounding environment.

The surfaces

What soft washing is for

  • Render

    Render is what soft washing is for. Low-pressure application, given time to work, then rinsed down.

  • Brick & Masonry

    Organic staining and efflorescence are lifted with the solution rather than with pressure, so the mortar joints are left alone.

  • Cladding & Timber

    Composite, timber and fibre-cement boards are treated gently — gentle application, gentle rinse.

  • Roofline & uPVC

    The black streaking down fascias, soffits and gutters comes off with the right solution, leaving an even finish along the whole run.

What we do

Surface-Specific Soft Wash Treatments

We most commonly recommend soft washing for render and painted masonry, timber and composite decking, cladding, soffits and fascias, and brickwork, fencing and exterior plastics.

During your free site assessment, we will inspect the surface, assess its condition and identify the type of contamination present. We will then explain whether soft washing is the most suitable option and recommend a treatment specifically suited to your property.

Planting and paintwork are protected first, the solution is applied and left to act, the surface is rinsed down, and Chiltern EverGuard™ is applied at the end.

What we soft wash

  • Render and painted masonry
  • Timber and composite decking
  • Cladding, soffits and fascias
  • Brickwork, fencing and exterior plastics

Our soft wash treatment service

How we do it, step by step

Every property is different. We start with a free site visit, assess the surfaces, then choose the method and the pressure that suit them.

  1. 01

    Site visit & assessment

    We assess the surface, its condition and its detailing to confirm soft washing is the right approach before anything is applied.

  2. 02

    Property protected

    Planting, lawns, glass and paintwork are covered or wetted down before anything is applied.

  3. 03

    Low-pressure application

    A specialist solution is applied at low pressure and given time to work on the algae, mould and organic growth.

  4. 04

    Gentle rinse

    The surface is rinsed down carefully once the treatment has done its work, and the planting is rinsed off with it.

  5. 05

    Chiltern EverGuard™ treatment

    Chiltern EverGuard™ is applied once the surface is clean. Protection typically lasts between 12 and 24 months, depending on the property's location, surrounding environment, surface type and ongoing maintenance.

The issues

Common Exterior Problems We Solve

  • Algae and organic staining
  • Black streaking and surface discolouration
  • Moss and lichen build-up
  • Weathering across render and exterior finishes
  • Dirt and staining on gutters, soffits and fascias

The result

An Even Finish Across The Whole Elevation

The treatment is applied evenly across the whole elevation, so the finish comes back evenly.

That includes the parts nobody cleans: the gable you only see from the garden, the run of fascia above the conservatory, the shaded north wall. We quote the whole elevation rather than the easy part of it.

Why it matters

What a soft wash treatment includes

  • Low-Pressure Throughout

    Render, cladding and brick are cleaned by the solution rather than by pressure.

  • Tailored Cleaning Methods

    The method is matched to each surface and its condition.

  • Even Across The Elevation

    Algae, black streaking and organic growth removed across the whole wall.

  • Chiltern EverGuard™ Included

    Applied once the surface is clean. Protection typically lasts between 12 and 24 months.

Included with every soft wash

Chiltern EverGuard™ On Every Soft Wash

Chiltern EverGuard™ is applied to every soft wash once the surface is clean. Protection typically lasts between 12 and 24 months, depending on the property's location, surrounding environment, surface type and ongoing maintenance.

Questions

Soft Wash Treatment FAQs

What is soft washing?

Soft washing is the low-pressure application of a specialist treatment, rather than cleaning with high-pressure water. We use it on render, brickwork, cladding, and gutters, soffits and fascias.

Do you soft wash render?

Yes — render is one of the surfaces soft washing is meant for. We'll check the condition of yours at the site visit before anything is applied.

Can you remove black streaks from gutters and fascias?

Yes. Black streaking on uPVC gutters, soffits and fascias is removed with the correct cleaning solution, restoring a clean, uniform finish along the roofline.

How long does a soft wash last?

Chiltern EverGuard™ protection typically lasts between 12 and 24 months, depending on the property's location, surrounding environment, surface type and ongoing maintenance. We'll advise on a maintenance interval for your property.

Will the treatment harm my plants or lawn?

Planting is covered or thoroughly wetted down before we start and rinsed off afterwards. We build the time for that into every job.

My render is cracked. Can you still clean it?

Usually. We'll look at it at the site visit, keep the pressure low, and point out anything we think wants a renderer's attention rather than washing over it.
