Render cleaning FAQs — Portsmouth
- How long does a render clean take in Portsmouth?
- Most semi-detached properties in Portsmouth are treated in a single day. Larger detached homes may need a second visit to give the biocide time to fully work through heavier staining.
- How long will the results last?
- Soft wash kills algae at the root, so results in Portsmouth typically stay clean for 2 to 4 years depending on aspect, tree cover and the South East climate. Every clean is backed by our 12-month finish guarantee.
- Do you clean K-Rend in Portsmouth?
- Yes — K-Rend is one of the most common surfaces we treat in Portsmouth. We use a manufacturer-approved biocide that lifts black algae and red K-Rend dust without damaging the silicone finish.
- Will high pressure damage my render?
- Yes. High pressure can blow the colour layer from modern silicone and acrylic renders and force water behind the system. Every job we do in Portsmouth uses the soft wash method instead — low pressure, chemistry-led.
