EXCELLENT Based on 1845 reviews Posted on Google Rebecca WilliamsTrustindex verifies that the original source of the review is Google. We are providing this review on the day of installation. We had DPC Plus installed. Installers arrived on time, were professional and completed the work to a good standard.Posted on Google Michal KvočekTrustindex verifies that the original source of the review is Google. I had a survey carried out to check for a possible damp or mould issue in my flat. The surveyor (Johnny) was very professional, thorough, and honest. After a careful inspection, he confirmed that there wasn't a problem they could help with. I really appreciated his approach because the survey was free, and he could have easily tried to find an issue that wasn't there. Instead, he was honest and gave me some genuinely useful advice on how to prevent future problems. I would definitely recommend their service.Posted on Google Andrew HattonTrustindex verifies that the original source of the review is Google. From survey to completion the service was excellent.

Cavity Wall Insulation Extraction in Bolton
Defective or waterlogged cavity wall insulation can trap moisture within the walls of your Bolton home and may lead to damp problems inside the property. Our cavity wall insulation extraction service removes damaged or saturated insulation materials safely and efficiently, helping your external walls function properly again and reducing the risk of ongoing moisture related issues.
These problems can develop when insulation has been installed incorrectly in the past or when moisture has gradually entered the cavity due to prolonged weather exposure.
Cavity Wall Insulation Extraction
Older or poorly installed cavity wall insulation can cause a range of problems within your home, including damp patches, mould growth and reduced energy efficiency. When insulation materials break down or become saturated with moisture, they can trap water inside the cavity.
Solution: Our cavity wall insulation extraction service in Bolton safely removes defective or waterlogged insulation materials. This process clears the cavity fully, allowing the walls to dry out and function as intended while helping to prevent further moisture related problems inside your home.

What is cavity wall insulation and how does it work in Bolton homes?
Cavity wall insulation is a method of filling the gap between the inner and outer walls of a property with insulating material. Many homes across Bolton were built with cavity walls to prevent rain from penetrating through the brickwork. However, these cavities can allow heat to escape if they are not insulated. At Home Energy Save GB, we install specialist insulation materials inside the cavity which slow down heat loss. This helps keep your Bolton home warmer during colder months and can reduce the amount of energy needed to heat the property.
Are homes in Bolton suitable for cavity wall insulation?
Many properties across Bolton are suitable for cavity wall insulation, particularly homes built between the 1920s and the 1990s. However, suitability must always be confirmed through a professional survey. At Home Energy Save GB, we carry out a free borescope inspection before any installation begins. This allows our surveyors to check the condition of the cavity walls and make sure they are free from excessive debris, moisture or structural issues. If your property meets the necessary requirements, cavity wall insulation can significantly improve comfort and energy efficiency.
How much heat can cavity wall insulation save in a Bolton property?
A large amount of heat can escape through uninsulated cavity walls. In many homes across Bolton, this can account for up to a third of total heat loss. Installing cavity wall insulation helps reduce this loss by slowing the transfer of heat through the external walls. This means your home retains warmth more effectively during colder weather. At Home Energy Save GB, we regularly help Bolton homeowners improve their home’s thermal performance, which can lead to lower energy bills and a more comfortable indoor environment throughout the year.
What insulation materials are used in cavity wall insulation?
Several different insulation materials can be used for cavity wall insulation depending on the property and cavity condition. At Home Energy Save GB, we use high quality materials designed to provide long lasting thermal performance. These materials may include mineral fibre or bonded bead insulation systems which fill the cavity evenly and effectively. Each system is designed to resist moisture and maintain its insulating properties over time. Our surveyors will recommend the most suitable insulation solution after inspecting your Bolton property and assessing the condition of the cavity walls.
Will cavity wall insulation cause damp problems in Bolton homes?
When installed correctly in a suitable property, cavity wall insulation should not cause damp problems. Issues usually occur when insulation is installed in unsuitable walls or when the cavity contains existing moisture or debris. At Home Energy Save GB, we always carry out a detailed borescope survey before recommending installation. This allows us to inspect the cavity and make sure it is in the right condition. By following strict installation standards and surveying procedures, we help ensure cavity wall insulation performs safely and effectively in Bolton homes.
