How We Approach Red Algae Removal
Good exterior cleaning is about choosing the correct process for the surface, not just turning up with a pressure washer. This is especially important for render, sandstone, porcelain, tarmac, block paving and stain removal.
1. Assess the surface
We check the material, staining, drainage and access so the cleaning method is suitable before starting.
2. Prepare and clear
Loose furniture, debris and obvious loose dirt are moved or cleared where practical.
3. Clean with the right method
Pressure, flow, surface cleaner, soft wash or treatment is chosen based on the job rather than a one-method-fits-all approach.
4. Treat specific staining
Black spot, algae, oil, rust, grease or render staining may need targeted treatment rather than water alone.
5. Rinse and check
The surface is rinsed, checked and touched up where needed so the final result is clean and consistent.
Price Guide & What Affects Cost
Red algae removal is quoted based on wall size, height, access and severity. Low-pressure treatment is usually used rather than aggressive pressure washing.
- Size of the area to be cleaned
- Surface type and how delicate it is

FAQs About Red Algae Removal
How much does red algae removal from render cost in Devon?
The cost depends on the area size, surface, access and level of staining. For Devon jobs, we usually price from photos first and confirm anything unusual before booking.
Can you quote red algae removal from render from photos?
Yes. Clear photos or a short WhatsApp video are normally enough for an initial fixed quote, especially for patios, driveways, paths and smaller exterior cleaning jobs.
Is red algae removal from render safe for the surface?
Yes, when the correct method is used. We adjust pressure, nozzles, flow rate and treatment depending on the surface rather than treating every red algae removal from render job the same.
Do you use chemicals?
Only where they are useful and suitable. Organic growth, black spot, oil, rust, grease and render staining often need different treatments. We avoid unnecessary chemical use where a water-only clean is sufficient.
How long does red algae removal from render take?
Small areas may be completed in a few hours, while larger or heavily stained surfaces can take a full day or more. The quote will explain what is involved.
Do I need to be home?
Not always. If access and water are available and everything has been agreed beforehand, many jobs can be completed while you are out.
Do you cover Exeter and Devon?
Yes. Pressure Washing Exeter is based in Exeter and covers Exeter, East Devon, Mid Devon, Teignbridge, Torbay and wider Devon depending on the job size.

Professional cleaning uses higher water flow, better surface cleaners, appropriate treatments and experience with delicate or stained surfaces. This usually gives a deeper and more even result than a domestic machine.
Can render be pressure washed?
Render should usually be cleaned with low pressure and suitable treatment rather than aggressive pressure washing. High pressure can mark or damage some render systems.
