FAQs
Why do homeowners choose to render their home?
People choose to render their homes for a variety of reasons. Some want to improve the curb appeal of their home, which the right render will certainly do. Others want to solve the problem they have with moisture penetrating their exterior walls damaging framing, insulation, wiring and other things. Some are most concerned with making their home more energy efficient. While still others are looking for a cost-effective way to extend the life of their home. Some people do it for all the above reasons and more.
Do you need planning permission to apply external rendering?
In some cases, a rendering project will be considered “permitted development”. This is usually the case if the render will not fundamentally change the appearance of the house. In other cases, however, planning permission will be required. For example: if the home is a Listed Building, or if it is located in a National Park or other Conservation Area. Planning permission will also likely be required if the render will significantly change the look of the house.
What’s the best type of external wall insulation for a moisture problem?
It is generally agreed that a silicone render is best for alleviating a moisture problem. Silicone rendering is extremely hydrophobic and quite breathable. They are also flexible so cracks that might let in moisture are unlikely to appear even if the house settles. If there is a downside to silicone renders it’s that they are among the most expensive types of render. But in this instance, it’s a case of getting what you pay for.
What’s the best type of render for an old house?
Old homes present unique problems when it comes to rendering, but most professional renderers agree that a lime render is your best choice for an old house. Lime is very flexible (important since most old houses tend to settle). It’s also quite breathable, which prevents moisture from collecting behind the render layer causing slow-motion damage. A lime render also tends to produce a more traditional look than other renders. And because it’s a natural material it is one of the most eco-friendly render types.
