What to do if you spot a crack in your home’s exterior


The most unwelcome of house guests, cracked render is only ever greeted with a grimace. As with any other failing fixture in your home, it doesn’t take all that much for a great deal of anxiety about the sure-to-be costly solution to the problem to creep in. It doesn’t help that a crack in your home’s exterior seems like as major a problem as you are likely to encounter; it is literally a hole in your home’s defenses.  

Panicking, ill-advised on the matter and desperate for a short-term fix, it is far too easy to fall into the trap of paying an exorbitant sum for an ultimately unhelpful stopgap solution. At All Weather Coating, our twenty years’ experience repairing external rendered walls have allowed us to perfect a definitive response that will not only repair the affected area, but keep it from returning for a minimum of 25 years. To guide you through this process, from the initial shock of spotting cracked render, right through to the paint drying on your new, glossy, reinforced exterior, we have put together this guide to repairing cracked render walls.

Once you have successfully identified a crack in your home’s exterior render, there isn’t much time to spare. Left unattended, an insignificant looking tear in your exterior wall can quite quickly escalate into a more serious structural flaw. Even a tiny crack can allow water to seep into your home, which can cause thousands of pounds worth of damage to your home – damp can be absolutely devastating. And once water has been granted access, you can’t exactly ask it to politely leave, the damage is already done. All of these issues stem from the cracked render, which hopefully demonstrates the importance of acting as quickly as possible.

You can contact us by phone, email or through the contact form on our website, whichever you prefer. From there, we can organise a date for our team to visit your home, hear your concerns and fully assess the affected area. Mapping the presence of any flaws in your home’s exterior allows us to formulate a detailed plan of the work to be done. Upon your approval, work can begin.

Prior to work on the affected area commencing in full, the rest of your home has to be covered. With windows, doors and all other at-risk areas suitably outfitted in protective paper and tape, the team can then start repairing cracks in external rendered walls. A combination of special bonding primers, sand and cement account for larger cracks while epoxy resin is used to fill smaller ones.

Exterior wall rendering repair work having been completed, the area is then thoroughly cleaned. Grime, moss, algae and flaking paint are removed using a wire brush, leaving a paint-ready surface behind. With a pump that allows its wielder to meticulously control the ratio of air to the weatherproof coating applied to a surface, a member of our team will coat your home’s exterior in wall coatings of your preferred texture and colour.

The experience of our staff, the sophistication of our equipment and the quality of our wall coatings all combine to distinguish our own service from that of our competitors. If you are in need of house rendering in London, All Weather Coating is the only choice.

Why cracked render repair is so important

repairing cracks in external rendered walls

Walk almost any street in the UK, glance around, and you will see that many of the homes surrounding you are rendered. Here, we take this additional layer of cement, lime and sand almost for granted. To us, a home isn’t a home without it. But why is that the case? Does external render repair fulfil an aesthetic purpose or a practical one – or maybe even both? To answer these questions, and to explain the importance of repairing cracks in external rendered walls, we have put together this post.

Repairing external rendered walls improves the appearance of your home

When it comes to our homes, whether we’d like to admit it or not, often our first consideration is an aesthetic one. If it doesn’t look good, why would we be interested? As the outermost layer of our home, render certainly plays a defining role in shaping its appearance. Done correctly, repairing cracks in external rendered walls can have a transformative impact – taking a worn down, tired exterior and changing it into a gleaming surface. The external waterproof render used can be tailored to match both the texture and colour of your home.

Silicone render improves the durability of your home’s exterior

First and foremost, external render serves a protective purpose. Composed of the right blend of materials and minerals, an exterior render mix should be more than capable of deflecting whatever conditions the weather can inflict upon your home. Imbued with water-resistant silicone, our exterior render paint is able to emerge unscathed irrespective of conditions – whether temperatures are high and low or conditions are windy and rainy, they will fail to have an impact. Without render, you lose this layer of protection and your home is left vulnerable to the elements, which is why it is so important to conduct external wall crack repair as soon as even a hint of a problem materialises.

Exterior wall rendering helps insulate your home

A less important but nevertheless significant property of the best exterior render paints is their ability to insulate. As well as keeping the outside world out, it is also capable of helping your home keep heat in. By increasing the breadth of your home with another layer of material, it bolsters your home’s ability to retain heat – a quality that will help lessen the load on your finances by minimising the amount of resources you have to expend to maintain the temperature of your home. If your home’s render becomes damaged, you lose this crucial buffer zone that provides both warmth and protection.

Rendering a house: before and after

In summary then, a fully rendered home holds a number of advantages over one that isn’t. Aesthetically superior, more durable and financially sustainable, it is easy to see why rendered homes have become both the norm and the standard. Repairing cracked render walls can be completely painless with a wall coating specialist on side.

How to identify and repair cracked external render

How to repair cracked external render

‘Exterior rendering’. You may never have actually heard the term before, but if you want your home to have any chance whatsoever of standing up to the weather for years to come, you are going to want to get it acquainted with it – and fast.

Fortunately for you, we have put together this post that aims to outline everything you need to know. In this crash course on rendering you will learn how to identify whether your home’s render requires replacing as well as how and why getting the rendering process right is so important.

What is render?

Fundamentally, render is a mixture of cement. External render is the outermost layer of your home and – as the outermost layer of your home – it is tasked with braving rain, wind, sleet, snow and sun and emerging unscathed.

How do I know if my home needs rendering?

Identifying whether your home exterior needs a refresh can be relatively straightforward – it all depends on the current state of your home’s exterior. Cracks and crevices are of course an obvious signifier of a problem.

On the other end of the scale, less visible but just as serious, is an inadequate product coating your home. Unfortunately, most masonry paints aren’t designed in the same way as weatherproof coatings are, meaning that they are unable to mount a serious and sustained defence against the attacks of the weather.

So, unless your exterior surface is flawless or you have recently invested in a quality weatherproof coating for your home, it is well worth considering the merits of exterior wall rendering.

Why choose All Weather Coating to carry out the rendering process?

From the start of the external rendering process to the end, we take repairing cracks in external rendered walls very seriously. Before the actual work begins, a survey is conducted to uncover and document every flaw.

From there, using the original survey, every flaw is corrected with meticulous care and precision.

House rendering: Everything you need to know

external render repair

A tried and tested exterior wall rendering service can allow a property to withstand the elements for decades without accruing even a single blemish.  On the other hand, a building that is woefully under-equipped to deal with the everyday stresses of the weather can very quickly deteriorate. How exposed a property is will of course affect the rate at which it does so. But rather than blaming a property’s location for its demise, it is instead more important to accept that all home exteriors incur damage at the hands of the weather. For this reason, it is vital to have some kind of barrier or buffer zone between your home and the weather. The last, and arguably most important, line of defence against marauding weather is your home’s external render. To learn how to maximise its effectiveness – as well as how to repair external render – we have put together this guide to everything you need to know about external rendering.

Exterior wall rendering

As your home’s final line of defence against the elements, it is essential that your house exterior rendering is not only intact, but is also hardy enough to fend off whatever the weather can throw at it. Cracked render needs addressing as soon as it materialises. Rain can quickly accumulate in crevices and cracks before gradually seeping into your home over time. If you do not act swiftly, you can have a very serious penetrating damp situation on your hands. In order to combat penetrating damp, it is worth considering our penetrating damp treatment.  If you want to cut the problem off at its source however, you will need to consider external render repair. Rendering external walls is straight-forward with All Weather Coating on your side, you can simply relax while we do the work, safe in the knowledge that our team are specialists in their field using the best products available (like K Rend).

Pebbledash repair

Repairing pebbledash render meanwhile can be a slightly most cumbersome task. The haphazard arrangement of small stones and rocks makes pebbledash an incredibly unwieldy surface to address – no matter how you choose to do so. Whether you decide to completely remove the existing layer of pebbledash, add another layer of pebbledash on top of it, or decide merely to gloss over any glaring vulnerabilities with an additional layer of paint, you are likely to struggle equally.

All Weather Coating’s pebbledash repair service will make your life a whole lot easier. An experienced group of specialists can resolve your pebbledash issue in a matter of days – for a fraction of the cost of pebbledash removal too.  Using the latest in wall coating technology, our exterior wall coatings are applied methodically and uniformly, ensuring a single speck isn’t missed.

How to Repair Cracked Render

Cracked Render Repair Services

Starting out as nothing more than a tiny fracture on your home’s exterior, cracked render may seem like a non-issue, but left unattended, it can easily spiral into a major structural issue (not to mention an aesthetic one). Damp can very easily become part of the furniture of your home, making it essential to address any cracks and crevices the instant they appear. The good news is that repairs can be swift and painless – close to two decades of restoring render in UK homes have taught us that.

If you have noticed a crack in your home’s external render, here’s how you can go about repairing it and ensuring that it never becomes an issue again.

What causes render to crack?

Low quality and ill-protected render will always be exposed in testing weather conditions. More often than not though, the way in which the render is applied is just as important as its quality, which serves to highlight the importance of hiring a cracked render repair service rather than taking matters into your own hands.

Applied in the wrong weather conditions, render will fail to last. If the temperature is too low (below 5°C), the curing process will stagnate, causing moisture to be trapped within the render. Too high, and the render will dry out too quickly, resulting in the formation of cracks.

Any form of precipitation is no ally of rendering either – rain, snow and sleet will adversely affect the moisture levels in the render, culminating in shrinkage cracks.

Why is it so important to repair render?

Cracked render is a route through which water can infiltrate your home. Water ingress will lead to perpetual damp in your home – rendering your home cold and damp – the opposite of what a home should be. Over time, continued damp will cause your home to deteriorate drastically; wallpaper will loosen and paints and plasters will decay.

Alongside the practical ramifications of living in a structurally unsound home, there is an array of associated health risks. Bacteria and dust mites flourish in damp conditions, allowing respiratory illnesses to run riot.

How to repair cracked render?

Firstly, we ensure that all areas not being treated are covered – paths and gardens with dust sheets and windows and doors with paper and tape. Small cracks are filled with epoxy resin while larger cracks are treated with special bonding primers before being filled with a sand and cement mixture.

After the render has been given ample time to dry and solidify – and a comprehensive cleaning process has been completed – it is time for the application of a silicon-based weatherproof wall coating. Mixed with an appropriately coloured final coating, the waterproof wall coating is applied using a pump that carefully regulates the ratio of coating to air, resulting in a perfect finish that will protect your home from damage for 25 years.

Your guide to rendering pebble dash

Pebbledash Repair

Pebbledash, a staple of home exteriors up and down the country, can be tricky to resurface when it begins to fall apart – which is inevitable given that the majority of them were first formed around 70 years ago during the post-war boom. So, if you’re stuck with a crumbling façade of sand, cement and pebbles, what should your next move be?

To help you answer this question, we have put together this guide to everything you need to know about pebbledash.

But first, we have to define exactly what pebbledash is. The exterior wall surface is formed when an array of pebbles are literally thrown at wet render, creating the pebble-strewn walls we are all so familiar with today. It differs slightly from roughcast render, which we could call its cousin. Instead of the pebbles being thrown into the render, roughcast render is formed when the pebbles are already incorporated into the mix of lime, cement, sand and water that we call mortar. Pebbledash then, perhaps the most haphazard of wall surfaces, can also seem to require an equally haphazard solution.

How to remove pebbledash?

Removing pebbledash is an extremely arduous and risk-laden endeavour. Ripping pebbledash forcibly from the walls of your home is bound to invite all kinds of structural issues – not to mention the potential invalidation of your home insurance.

How to cover pebble dash?

One of the first questions that generally pops into their heads of deteriorating pebbledash owners is how can I cover it up? And that is a good question for two reasons – aesthetically, patchy pebbledash is far from pleasing and practically, patchy pebbledash can allow heat out of your home and water into it.

As ever, the answer to this question depends on the ins-and-outs of the individual situation (we will always dispatch a qualified surveyor to comprehensively assess your site before beginning work). One solution which won’t work is the introduction of another layer of pebbledash – your home won’t be able to bear the increased weight. Pebbledash can be covered though; it just has to be done so with a substance that is up to the job, which leads me to the next common question…

How to paint pebble dash?

Paint, as a method of cover, is a no-go. Regular masonry paint is ill-equipped to create a protective weatherproof seal around brickwork. If that wasn’t already enough, the time-consuming nature of such an undertaking is enough to completely derail any hopes you may have harboured of simply painting over your damaged pebbledash. By hand, painting over pebbledash is excruciatingly long-winded and even once accomplished, you can’t be sure that you have covered all the cracks and crevices that are custom to a pebbledash exterior.

Weatherproof wall coatings are another matter altogether however. Many times thicker than traditional paint and infused with weather-resistant silicon, wall coatings are perfect for pebbledash repair. Applied using a highly sophisticated pump that carefully controls the ratio of air to coating, you can be certain to receive a perfectly distributed covering.
