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.

- Inspect the condition of the wall cavity using specialist borescope equipment, allowing our surveyors to look inside the walls accurately while keeping disruption to your home to an absolute minimum.
- Check for any issues inside the cavity, including rubble, debris, damp or other obstructions that could affect the performance of the insulation or reduce its long term effectiveness.

Cavity Wall Insulation Extraction in Southport
Defective or waterlogged cavity wall insulation can trap moisture within the walls of your Southport home and may lead to damp problems developing inside the property.
These issues can arise when insulation has been poorly installed in the past or when moisture has gradually entered the cavity over time. Southport’s coastal location means properties are often exposed to driving rain, strong winds and higher levels of moisture in the air. This can increase the chances of water finding its way into wall cavities, particularly in older homes built with traditional masonry construction.
Cavity Wall Insulation Extraction
Older or poorly installed cavity wall insulation can cause a number of problems within your Southport 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 Southport carefully removes defective or waterlogged insulation materials from the cavity. By clearing out the failed insulation, the wall cavity can begin to function properly again, allowing trapped moisture to escape and helping to reduce the risk of ongoing damp related issues inside the property.

How much heat can cavity wall insulation save?
A large amount of heat can escape through uninsulated walls. In many homes, up to a third of heat loss can occur through the external walls if the cavity is empty. Installing cavity wall insulation helps reduce this heat loss by slowing the transfer of heat through the walls. For homeowners in Southport, this means properties can stay warmer for longer once the heating is turned on. As a result, many households notice improved comfort levels inside their home as well as a reduction in the amount of energy needed to maintain a comfortable indoor temperature.
How do you check the condition of the cavity walls?
Before installing insulation, we carry out a detailed borescope survey. This involves drilling a small access hole and inserting a specialist camera into the cavity wall so we can inspect its condition. The survey allows our team to check for debris, moisture, previous insulation or structural concerns that may affect the installation. This careful inspection ensures the cavity wall is suitable for insulation and helps prevent future issues. For homeowners in Southport, this step provides reassurance that the work will be completed safely and effectively.
What type of insulation materials are used in cavity walls?
Several types of insulation materials can be used for cavity wall installations, including mineral wool fibres, polystyrene beads and specialist foam products. The most suitable material will depend on the design and condition of the property. At Home Energy Save GB, we assess each Southport home individually before recommending the best insulation option. Our goal is to ensure the material used performs effectively, fills the cavity properly and provides long lasting thermal performance.
Will cavity wall insulation affect the appearance of my home?
The appearance of your home should not change noticeably once the installation has been completed. The holes drilled during installation are small and are filled with mortar that closely matches the existing joints in the brickwork. Our installers take care to complete this work neatly so the finished result blends in with the surrounding wall. For homeowners in Southport, the visual impact is minimal and most people find the repairs are barely noticeable once the work is finished.
How can I arrange a cavity wall insulation survey in Southport?
Arranging a survey is straightforward. Homeowners in Southport can contact Home Energy Save GB to book a free borescope inspection of their property. Our team will visit your home, assess the condition of the cavity walls and explain whether insulation would be suitable. We will also answer any questions you may have about the installation process and expected benefits. This initial survey helps you make an informed decision about improving the energy efficiency of your home.
