initial inspection and survey
We always arrange a free site survey before providing a no obligation quote for cavity wall insulation. As you can imagine, every home is different and it is essential that the property is inspected before agreeing to any works.
At the survey, initially we will visually inspect the walls to determine whether there are signs of a previous installation. If there are no previous injection points present, we will conduct a drill test and boroscope check.
A small hole (12-14mm) is drilled in an inconspicuous area on each elevation and a camera is inserted. This allows us to inspect the condition of the cavity, ensuring there is no rubble or debris bridging the gap. A cavity wall can only be insulated if it is clear of any rubble or debris. All holes drilled will be effectively sealed to prevent water ingress.
The cavity width will also be measured. The cavity must be a minimum of 50mm in order to be filled with our cavity wall insulation. This allows the material to spread evenly throughout the wall ensuring there are no voids!
Damp proof courses (DPC) will be inspected to make sure they are of adequate height above ground level and any remedial action required pointed out to the occupant or owner.
We will assess the access around the property and check any fuel burning appliances within the home. Certain appliances may require additional combustion ventilation and this will be explained should they be required.
We’ll then take some measurements and provide you with a quote!

installation process
On the day of install, the installer will carry out their pre-install checks. A quick walk around the property to make sure everything is as it should be on the survey and a risk assessment carried out. They will also need to check any heating or fuel burning appliances within the property.
We recommend any photo frames, mirrors or ornaments on external walls and window sills be removed as the drilling can cause some vibration to the wall.
Once all checks are complete, a power point either internal or external should be provided so that the drilling can begin. Holes are drilled at approx. 1.35m intervals through mortar joints, as set out by the system manufacturer.
Once all the holes are drilled and any combustion vents or barriers installed, the filling process can commence.
The walls will be filled usually from the rear of the property, starting with the lowest holes first and working our way to the top of the house. Each hole will be made good as we go to match the existing finish. Once dry you shouldn’t notice that we’ve been!
Your property will then be tidied up and you are free to have a look yourself to ensure you are completely satisfied before we leave.

combustion ventilation
As mentioned, certain appliances require additional ventilation for combustion in order to function safely. If no existing vent is present, a 5″ core vent will be installed to meet this legal requirement. Below are some of the appliances which may be affected:
- gas fires with a heat input rating over 7kw
- decorative fuel effect gas fires of any kw rating
- wood burners with a heat output rating over 5kw
- open fires
- open flue gas or oil boilers
- Aga or Rayburn cookers
