Cavity wall refurbishment
How we give your cavity walls a fresh, new start
Cleaning out wall cavities is an essential part of property maintenance and needs to be undertaken before new insulation materials are installed.
At Viridian, we offer three ways to thoroughly clean and prepare your cavity walls for a new, fresh product all of which are part of our industry-leading cavity wall refurbishment services.
With our cavity wall cleaning, we get rid of waste mortar on wall ties and dust build-up with a specialised industrial-grade compressor and whip set. This process is less labour-intensive and removes smaller debris and dust within the wall cavities.
Our rubble removal requires more intensive manual labour where our installers physically have to remove rubble and bricks that are lodged in the cavity. This process is only required when there are larger objects which our equipment cannot extract and would otherwise cause internal property damage and damp issues.
We can also carefully remove and dispose of old insulation materials – this is our cavity wall insulation removal – a separate service which you can learn more about on our dedicated page.
Cavity wall insulation products are only effective when installed in clean wall cavities by trained installers.
Following a professional process
Our team will begin by completing combustion appliance and flue safety checks if they are needed.
We then drill access holes in the wall in the same way as we would for installing wall insulation and remove just enough bricks (usually only two or three) close to DPC level to act as extraction points. We use specialised brick removal tools to do this, making sure your bricks are removed cleanly and remain whole, so they can be put back into place afterwards without any mismatches.
We use these access points to carry out cavity wall cleaning by removing small debris and dust, as well as mortar on your wall ties. If recommended by our surveyor, we can also carry out additional removal of rubble and larger objects, the process of which takes a little longer, as it is more labour-intensive, and we may have to take out additional bricks to remove any obstructions.
After your cavity wall refurbishment is complete, we reinstate the bricks, and if your property has a render, pebble dash or similar finish we will recreate it as closely as we can. If we are installing new insulation for you, we’ll do so, and once all works are complete, we re-fill the drill holes with mortar of a similar type and colour.
Finally, we carry out post-installation checks, including a second combustion appliance check, making sure all the under-floor and combustion vents are clear, and that everything is completed properly.
By Viridian’s insulation experts
Before you meet your cavity wall refurbishment specialists, our qualified surveyor will cover the possible cavity wall cleaning cost or whether additional removal of rubble or old insulation material is required. All of this information is clarified as per our industry-leading survey process.
We only use our own trained and certified specialists to clean wall cavities, extract old insulation materials and carry out combustion appliance checks. These procedures are usually combined with the addition of a new, modern product.
We operate in Kent, Sussex, Surrey, and Greater London and offer bespoke professional services that add value to your home.
