Which options suit homes in Castle Vale?

Through-coloured render (K Rend type)

Single-coat or two-coat renders coloured through their whole depth, sprayed or trowelled and then scraped to a textured finish. Brands such as K Rend are widely used on new and existing homes. They don't need painting and hide small marks well, though they're best on walls with consistent backgrounds.

Sand and cement render

The traditional two-coat render of sand, cement and lime or plasticiser, finished smooth or textured and then painted with masonry paint. It's the most affordable system and easy to patch. It needs repainting every several years, and on older solid walls a breathable, lime-based mix is often better than a hard cement render.

What does your render cost in Castle Vale?

Guide prices start at £40 and run to £160 per m². Silicone render with base coat and mesh over sound brickwork, including beads: around £70–£100 per m².

Your questions answered

Can you render over my old render or pebbledash?

Sometimes. If the existing render is firmly bonded, some systems can go over it after cleaning and a key coat. Hollow, cracked or loose render must come off first, because new render won't hold a failing background. We tap-test the whole wall at survey and tell you which areas can stay.

Do I need to repaint render?

Sand and cement render needs painting with masonry paint, and repainting every several years. Silicone and through-coloured renders don't need painting, because the colour runs through the material. They may need an occasional gentle clean, especially on north-facing or shaded walls where algae can grow.

Does Birmingham City Council need to approve my render?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Castle Vale is provided by Birmingham City Council or a registered building control approver, and some work is self-certified by registered installers.
