How We Approach Render Stain 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
Black staining on render is priced by access, surface area and stain type. Some marks are organic and treatable; others may need specialist stain removal or careful expectation setting.
- Size of the area to be cleaned
- Surface type and how delicate it is

How much does black stain removal from render cost in Exeter?
The cost depends on the area size, surface, access and level of staining. For Exeter jobs, we usually price from photos first and confirm anything unusual before booking.
Can you quote black stain 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.

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.
