Green Render or House Walls? We Clean Them Properly.

Render often stains from algae, mould and organic growth, especially on shaded or damp walls. We use a 3 step softwashing method and targeted treatment to clean the surface without harsh pressure washing.

Step 1: Softwash Application

Professional softwash treatment applied to the render / walls, via gentle spray application and brush agitation to breakdown organic growth.

  • NO high pressure application

  • Chemically breaks down algae

  • Safer, cleaner treatment

Step 2: Low-Pressure Rinse

The surface is gently rinsed to remove loosened staining, dead organic growth and cleaning residue without damaging the render.

  • Gentle low-pressure rinse

  • Removes loosened staining

  • Safer for render & painted walls

Step 3: Future Protection

A professional biocide treatment is applied to target remaining organic spores and prevent algae re-growing for longer, prolonging the finish.

  • Targets remaining spores

  • Helps slow algae regrowth

  • Supports longer-lasting results

Why We Never Use High Pressure On Render

Render is a delicate exterior surface, so aggressive pressure washing can cause damage. Our process is designed to clean render safely, using softwash treatment, gentle rinsing and biocide protection designed to achieve the best result without unnecessary risk.

As with all of our work, we back the results with our industry unique👇

12 Month No Organic Re-Growth Guarantee

Where we have cleaned and treated a surface for organic growth, we guarantee the treated area against significant re-growth of algae, moss, lichen and black spot for 12 months from the date of service. If substantial re-growth occurs within that period, we will return and re-treat the affected area free of charge.

Pauline - Rochester

Joshua was prompt, polite and efficient and provided an excellent service. My neighbour also had her patio cleaned at the same time and was very impressed with the outcome

Michelle - Tonbridge

Not the cheapest quote, but by far the clearest. Everything measured and clearly explained. Glad we went with Elevated Exterior and the result was fantastic.

Philip - Sevenoaks

Josh is excellent and very professional. I feel he went above and beyond with our very large patio. His worked very hard and the patio and paths look fantastic

Frequently
 asked questions

How much does it cost?

Render cleaning prices depend on the size of the property, the amount of algae or staining, access requirements and the type of render. As a rough guide, a typical two-storey semi-detached render clean starts from around £165 per side.

We’re not usually the cheapest option because we don’t just blast the surface and leave. Our render cleaning process uses softwash treatment, gentle rinsing and biocide protection where suitable to clean algae, mould and organic staining safely.

For the most accurate quote, send a few clear photos of the affected walls and your postcode. We can usually give you a fast estimate without needing to visit first.

Why is my render green & stained?

Render usually turns green or stained because of algae, mould, lichen and organic growth building up on the surface. This is especially common on shaded, damp or north-facing walls where sunlight and airflow are limited. Over time, dirt, pollution, rainwater marks and biological growth can make render look tired, patchy and neglected. Professional render cleaning and softwashing helps remove the staining safely without harsh pressure washing, then biocide treatment can help slow future algae and mould regrowth.

Why do you use softwashing vs pressure washing?

Pressure washing can damage render, especially if the surface is cracked, blown, painted or delicate. High pressure can leave patchy marks, force water behind the render or damage the finish. That’s why we use render softwashing, gentle rinsing and targeted treatment instead of harsh jet washing.

Is there a best time of year to clean render?

Render cleaning can be carried out year round, but spring, summer and autumn are generally best. Warmer, drier weather helps softwash treatment and biocide protection work more effectively. If your render is already green, stained or covered in algae, mould or organic growth, it is usually better to clean it sooner rather than letting the staining get worse.

Can render cleaning damage plants or windows?

We take care around plants, windows, doors, painted surfaces and surrounding areas before applying any render cleaning treatment. Where needed, we pre-rinse, protect and rinse down nearby areas to reduce risk. Render softwashing should always be carried out carefully, especially around delicate finishes, glass, frames, lead flashing and garden areas.

How long does render cleaning last?

Results depend on the render type, weather exposure, shade, airflow and nearby trees or plants. Treated render usually stays cleaner for much longer than a simple rinse because biocide protection helps slow algae, mould and organic regrowth. Where we clean and treat render for organic growth, it is backed by our minimum 12-month no organic re-growth guarantee and we also offer 6-12 monthly biocide re-applications.
