6 benefits of re rendering your house

Considering re-rendering your house? Like any home improvement, it’s worth weighing up the benefits and considering whether they’re worth the cost. To make things easier, we’ve put together a list of six benefits of a house re-render and how the benefits of rendering with SprayCork go even further.

1. Appearance

Nothing beats the smooth, uniform finish you get from re-rendering your house. That’s a stark contrast to the visual impact of old, faded or cracked render. Even if your home is stunning on the inside, people can get a bad first impression from tired walls.

As you can see from the before and after images in the CorkSol gallery, a high-quality re-render can truly transform the appearance of your house – from old and worn to fresh and new. This is definitely one of the clearest rendering benefits.

On top of that, you can find render in a wide range of colours. With CorkSol, you can choose from over 30 colours of render to really give your house a makeover. Or simply opt for a shade similar to your existing render, to get the same look with a smooth, new finish.

2. Less hassle

When old render starts to crack, it’s only natural you want to fix or fill those cracks to stop water getting through and maintain your property’s appearance. But arranging and paying for those repairs (or even filling them yourself) can soon become tiresome and costly.

You can patch render by filling cracks or applying new render to blown sections. Unfortunately, this is more labour intensive than it sounds because areas need to be well prepared before filler or new render is applied. Additionally, the results rarely match the rest of the wall.

Alternatively, you can strip off the existing render and apply a fresh new coat. But that takes lots of time and effort, which in turn means higher costs from contractors. This is one area where the benefits of rendering with SprayCork are distinct.


A CorkSol re-coating will eliminate the need for crack repairs for several years, saving you plenty of time and money in the process. There’s no need to remove existing render as long as it’s structurally intact, meaning cracks can be eliminated without the lengthy removal process.

3. Thermal retention

With render typically lasting between 20 to 40 years, many houses will have render that was originally applied in the 2000s, 1990s or even the 1980s. Building materials have advanced significantly since then, meaning that render can now offer much more in the way of thermal efficiency.

Re-rendering your house will add an insulative layer on the outside of your walls, which makes it harder for heat to pass through while still keeping walls breathable. The result is a warmer home in winter and cooler in summer, so it’s easier to maintain a comfortable temperature. You could even save money on your heating bills over time.

Those rendering benefits get amplified with a high-performance product like SprayCork. Applied as an exterior wall coating, it’s proven to be 7-8 times more insulative than traditional render. As such, it can reduce your heating bills by up to 15%.

4. Noise insulation

It’s not just heat that modern render can block. With the right product, noise will find it harder to pass through too. Drawing on the properties of cork, SprayCork render can provide a reduction of up to 12dB in noise.

The result is a more peaceful environment with less noise from traffic, neighbours and any other noise outside your home. Whether you need to concentrate in your home office, relax in the living room or enjoy dinner in peace at the dining table, rendering benefits you and your family no end.

5. Weatherproofing

Let’s not forget one of the primary purposes of render – weatherproofing. When render becomes worn and cracked, it provides less protection for the brick walls underneath it. Over time, water can start to seep through, which creates a vicious cycle with even more cracks and holes.

When water gets through your render, it leaves your walls exposed. Over time, this can lead to penetrating damp. In short, water soaks the brickwork and gets inside your property. Untreated damp becomes mould, which can even cause health problems. Not to mention the eyesore on your internal walls, which will eventually need redecorating.

A CorkSol re-coating will ensure your walls are fully sealed from the elements, so you can wave goodbye to problems with water ingress and damp. We’re sure you’ll agree that’s a much better option than risking health complications and redecorating internally!

6. Longevity

There’s no two ways about it – re-rendering lasts longer than any makeshift solution like patching render or filling cracks as they emerge. A fresh coat of render will last decades rather than months or years.

As we mentioned earlier, this doesn’t have to mean stripping off old render and starting from square one. Despite there being no need to remove render before applying, SprayCork still stands the test of time with an impressive 25-year guarantee.

In other words, you can enjoy the benefits of rendering for years to come – such as thermal insulation, noise insulation, weather resistance and a stylish look. That’s paired with peace of mind, so you don’t have to keep checking on the condition of your render from year to year.

7. Value

Finally, there’s the value. Re-rendering your house with a modern render product like SprayCork helps you create a low-maintenance property with great kerb appeal that’s well insulated from heat and noise and protected from the weather.

As you can imagine, that’s a pretty attractive prospect for any buyer, which could result in increased value for your property.
