Rendering in Knowle

Before your render in Knowle

This kind of work rarely needs planning permission, but it does have to comply with Building Regulations, and some parts must be certified by a registered installer or signed off by building control. In Knowle, building control is provided by Solihull Council or a registered building control approver (formerly an approved inspector).

Hard cement render on old solid walls can trap moisture inside.
New render should stop above the damp-proof course with a bell-cast bead.
Downpipes, lights and satellite dishes on Knowle homes are removed and refitted around the new render.

Which options suit homes in Knowle?

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.

Render repairs

Cutting out hollow, cracked or blown render, treating any cause such as a leaking gutter or failed bead, and patching to match. Exact colour and texture matches are hard on painted or weathered render, so a repaired wall may need repainting or a full re-coat to look even. We'll be honest about whether a patch will blend.

Your questions answered

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.

How long does rendering take?

A typical semi takes one to three weeks, depending on how much old render comes off, the system and the weather. Each coat needs time to cure, and render can't be applied in frost, heavy rain or very hot sun. We plan the programme around the forecast and tell you about any delays.

Who approves rendering in Knowle?

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