Assist Rendering is here for you!

Welcome to the F.A.Q page

Here we will aim to answer any questions you have about rendering your house, why you should do it, and why you should do it through us.

If you have any questions that aren’t listed here don’t hesitate to contact us and ask- we’re happy to help any way we can!

Just found out about us and have a few questions about rendering?

See if they’re answered below!

  • There are many reasons why someone might consider rendering their house, from modernising the look of their home to fixing their mouldy green walls. You could even render your home simply because you like the colour options we offer.

    Rendering is a dependable way to weatherproof your home that also resists penetrating damp, that can last for years!

  • We offer several types of rendering that are listed below, you just need to choose which one is right for you and what you want for your home. We can offer:

    • Acrylic rendering gives a smooth or textured finish (depending on what you want) in an array of colours.

    • Pebble dash render contains pebbles that gives a decorative finish.

    • Silicone renders offer amazing waterproofing.

    • Tyrolean render has a rough, textured finish.

    If you want any additional information, let us know with an email or a phone call.

  • The good news is that we offer quotes, the better news is that our quotes are free! Check our quotes page to see what we need from you,why we need them, and receive your quote by email shortly after that.

  • Yes, we can render over brick and older render.

  • We have loads of colours for you to choose- anything between red to white. You could even have a neon pink house if you wanted! Just let us know and we’ll see what we can do for you!

  • Timber framed houses won’t be a problem, so if you’re interested just give us a message!

  • Our rendering products offer a 25-year guarantee, which includes cover from flaking and chipping.

  • We require a payment of 50% upfront.

We’ve talked about Rendering, but the homepage also talks about EWI.

Let’s see if we can answer your questions about that!

  • External wall insulation is a layer of insulation fitted over the outside walls of your house and is an excellent option for those with solid walls who can’t get cavity wall insulation.

  • Insulating your home helps to keep heat inside and lower your energy bills, which has the added benefit of lowering your carbon footprint. It also helps with reducing noise coming from outside your home, so noisy neighbours that are detached from your property will become much less of an issue!

  • Generally there is only 1 type of EWI that comes with several layers; the initial layer that is usually made from mineral wool or expanding polystyrene, though other materials are available, acts as the main source of insulation; next we add the primer that helps to waterproof the EWI; thirdly there is a fibre mesh to hold the primer in place as it dries, and then the final render of the EWI, which will be what everyone sees when they look at your house in the end.

  • EWI is installed by applying insulation to an exterior wall of your house, followed by the application of a mesh render, and then a final coat of render.

  • It’s valid to want to keep the front of your house looking like it always has- we’re partial to Victorian properties here ourselves!- so if you don’t want to cover your external walls don’t worry, we also offer internal wall insulation. Contact us and we can work together to find what’s best for you.

Is there some issue preventing you from getting EWI? No worries! We also offer IWI services.

Find some information on that below!

  • There are many reasons to opt for internal wall insulation over its outdoor counterpart, including a lower price and saving the exterior of your house being covered. IWI is an ideal choice for homes with solid walls or homes built before the 20th century. If it’s still a bit much for what you can afford, just like EWI, government grants are available to bear the brunt of the cost! Contact us to find out more about applying for a government grant.

  • Internal wall insulation is cheaper than external wall insulation and can be done room by room, which decreases the changes you need to make to your routine while installation is ongoing. Like the alternative, IWI also lowers your heat bills and improves the thermal energy efficiency of your home. It is also an excellent choice for those who can’t get planning permission for EWI, as oftentimes internal changes to the house don’t require permissions, or if you don’t want to cover the exterior of your house. Please check with your local council if planning permission is required for insulating your internal walls.

  • While cheaper than external wall insulation and offering many (or all) of the same benefits, internal wall insulation is on average less effective. This doesn’t mean IWI is a bad choice by any means, and in some cases is recommended over other types of insulations.

  • -what methods of iwi are there?

    There are 4 different methods to insulating your internal walls which we will go over briefly here. A more in-depth explanation can be found in the IWI section of our services page. The different methods of IWI are:

    • Batten wall insulation involves wood or metal battens being attached to the interior surface of your walls to create a framework, which insulation is then fixed between. This method has 2 different ways in which it can be accomplished, each offering different benefits. Batten wall insulation offers better moisture resistance and thermal performance to the alternatives.

    • Direct wall insulation involves applying insulation materials directly onto the existing wall, covering it in a vapour barrier, and finishing with durable plasterboard. This cost-effective and space-efficient method is ideal for homes with flat walls and very few damp issues. Requires some maintenance from your end.

    • Insulating plaster uses a specialised plaster made with insulating materials being applied directly to the interior walls of your room. This does not affect the floorspace of your home but it is less effective than the bulkier boards used in other methods.

    • Stud wall insulation involves building a 10cm (100mm) thick secondary wall with a 4cm (40mm) cavity between the internal wall and the insulation, allowing space for wires and pipes. More invasive and a bit more expensive but it’s ideal for walls that are prone to damp.

    This is one of the factors in determining the cost of your insulation.

  • Like the different methods of insulation there are 4 different types of insulation to choose from, making IWI one of the more versatile methods of home insulation. These types of insulation are:

    • Mineral wools available as semi-rigid boards or batts. This insulation can be made of heat-proof materials like stone or silica, and most include slag to increase the insulations fire resistance.

    • Natural minerals, like woodfibre, sheep wool, or cork. These materials have good levels of breathability and are very renewable, so it’s a good choice for those who are conscious of their carbon footprint.

    • Rigid foam boards are thinner, take up less floor space, and can also incorporate a vapour barrier. They are less breathable and more expensive.

    • Thin insulation, which means any insulation with a thickness of less than 25mm. This can require a bit less work on our end as it’s possible that fixtures on the affected wall can stay in their place, as we can cut around the insulation easier.

    This is one of the factors in determining the cost of your insulation.

  • For the average-sized room, installation will take about a full day, however this can vary depending on the size of your room.

    Fixtures attached to the wall, such as light switches and shelves, will need to be removed and the space around the walls adequately cleared and cleaned. We build what needs to be built (i.e. stud walls or battens), attach and secure the insulation boards. Lastly, the insulation is covered by plasterboard and fixtures that were removed from the wall are reattached. We’ll do one last examination to make sure everything is working as it should be and then move onto the next project.

  • Insulating your internal walls will eat into the space of your room by about 10cm (100mm), less if you opt for thin insulation of your walls.

  • Insulating the internal wall is naturally more disruptive than insulating or rendering the external walls, as our workers will need access to your home and furniture to be moved to give them adequate workspace. Disruption is mitigated as IWI can be done room by room, however the process of moving furniture and cleaning will need to be repeated for each.

You’re going ahead with us (yay!) and you have a few questions about the process.

Find the answers to your questions below!

  • It really depends on the type of building we’re working on- a group of flats would have different requirements to a bungalow, for example. Don’t worry, though, as we’re dedicated to working with you so you can do as little as possible and sit back while we handle everything else.

  • The main source of noise you and your neighbours need to worry about is the scaffolding going up and down, which won’t take very long at all. After that the process of installing your insulation and rendering your home won’t make so much noise at all, so binging your favourite programs should go on uninterrupted.

  • We’ll clean up after ourselves at the end of each day and keep a path to your house clear, leaving your days as uninterrupted as we possibly can.

  • Installing your EWI should take about 2 weeks, however this can vary depending on the size of your house and the weather. We can’t send our contractors out to work on top of scaffolding in a storm, after all!

    Installing IWI can take up to a full day for an average-sized room, however this can vary depending on the size of the room. The time it takes to install IWI varies depending on how many rooms receiving the insulation, the size of those rooms, and the type of insulation we are working with.
