Cavity Wall Insulation Extraction in Shrewsbury
Defective or waterlogged cavity wall insulation can trap moisture inside the walls of your Shrewsbury home and may lead to damp problems developing within the property.
These issues can arise when insulation has been poorly installed in the past or when moisture has gradually made its way into the cavity over time. Shrewsbury’s changeable weather and regular rainfall can increase the chances of moisture entering wall cavities, particularly in older properties. Over time this can cause insulation materials to become saturated or ineffective, preventing the cavity wall from performing as it should.
Cavity Wall Insulation Extraction
Older or poorly installed cavity wall insulation can cause a number of problems within your Shrewsbury home, including damp patches appearing on internal walls, the development of mould and a clear reduction in overall energy efficiency.
Solution: Our cavity wall insulation extraction service in Shrewsbury carefully removes defective or waterlogged insulation materials from the cavity.

Is my Shrewsbury property suitable for cavity wall insulation?
Many homes across Shrewsbury are suitable for cavity wall insulation, particularly properties built after the 1920s which were commonly constructed with cavity walls. This includes many semi detached and detached homes across residential areas of the town. At Home Energy Save GB, we carry out a detailed borescope survey before any work is recommended. This allows our team to inspect the cavity wall internally and confirm that the cavity is clear, dry and suitable for insulation. This assessment ensures that cavity wall insulation will perform effectively and safely within your property.
How does cavity wall insulation help reduce heating costs?
Cavity wall insulation works by filling the gap between the inner and outer walls of your property with insulating material that slows the movement of heat. Without insulation, a large amount of heat can escape through external walls. By installing cavity wall insulation, heat remains inside your Shrewsbury home for longer, meaning your heating system does not need to work as hard to maintain a comfortable temperature. Over time this can help reduce energy consumption and contribute to lower heating bills, particularly during colder months.
How do I know if my Shrewsbury home already has cavity wall insulation?
Many homeowners are unsure whether their property already has cavity wall insulation installed. During our survey, the Home Energy Save GB team uses specialist equipment such as a borescope camera to look inside the cavity wall. This allows us to confirm whether insulation is present and check its condition. In some older properties in Shrewsbury, insulation may have been installed many years ago and could be damaged or deteriorated. Our inspection helps determine whether existing insulation is performing properly or whether improvements may be required.
What is a borescope survey and why is it important?
A borescope survey is an essential part of assessing whether cavity wall insulation is suitable for your property. Our technicians drill a small access hole in an external mortar joint and insert a specialist camera into the cavity. This allows us to inspect the cavity wall internally and check for debris, moisture, or structural concerns. The survey helps us confirm that the cavity is suitable for insulation and prevents problems that can occur if insulation is installed in unsuitable conditions. This careful approach ensures installations across Shrewsbury properties are completed safely.
What type of insulation material is used for cavity walls?
Several types of insulation materials can be used for cavity wall insulation, including mineral fibre and bonded bead insulation systems. The most suitable material will depend on the construction and condition of your property. During our inspection in Shrewsbury homes, our team assesses the cavity width, structure and accessibility before recommending the most appropriate insulation solution. Using the correct material ensures the cavity is filled evenly and performs effectively for many years.
