FAQ

Frequently Asked Questions

Answers to common questions about our professional K Rend rendering, through-coloured finishes, and external wall insulation services in South Wales and South West England and across South Wales.

Does K Rend help with damp walls?

+

Yes, it is excellent for tackling damp. Because K Rend is silicone-enriched, it creates a water-repellent surface that stops rain from soaking into your masonry. However, it is also breathable, which means it allows moisture from inside the house to pass through the wall, reducing the risk of internal condensation and mould.

How long does K Rend last compared to traditional render?

+

Traditional sand and cement render often cracks and peels within 5–10 years because it is rigid and brittle. K Rend is designed to be flexible and durable. With professional installation and basic cleaning, it can last 30 years or more, and because the colour is through-and-through, it won't fade or peel like paint.

Will I need planning permission to render my house in Ferndale?

+

In most cases, rendering your home falls under "Permitted Development," meaning you don't need planning permission. However, if your home is a listed building or located in a conservation area, you will likely need approval. If you are also adding External Wall Insulation (EWI), which increases the thickness of the walls, we can help you check with the Rhondda Cynon Taf council or your local authority to make sure everything is above board.
