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.

Before any installation begins, we carry out a detailed borescope survey to make sure your cavity walls are suitable and in the right condition for insulation.

Cavity Wall Insulation Extraction in Warrington
Failed or waterlogged cavity wall insulation can hold moisture within the cavity and contribute to damp issues inside your Warrington home. Our cavity wall insulation extraction service safely removes defective or saturated materials, helping to restore the proper function of your external walls and minimise the risk of continued damage.
Problems often occur where insulation has been poorly installed or where rainwater has entered the cavity over time. Using specialist extraction equipment, our experienced team carefully removes the affected material, ensuring the cavity is cleared, dry and ready for any necessary remedial work or future insulation installation.
Cavity Wall Insulation Extraction
Old or poorly installed cavity wall insulation can lead to damp, mould growth and a noticeable drop in energy efficiency. When insulation materials deteriorate or become saturated, they can hold moisture within the cavity, raising the risk of structural damage and impacting the air quality inside your Warrington home.
Solution: Our cavity wall insulation extraction service in Warrington removes failed or waterlogged insulation safely and thoroughly, fully clearing the cavity to restore its correct function and safeguard the structure of your property.

How much heat loss can cavity wall insulation prevent?
Uninsulated cavity walls can account for up to a third of heat loss in many Warrington homes. By professionally installing high quality insulation, we significantly reduce heat transfer through external walls. This helps retain warmth during cold Cheshire winters and keeps indoor temperatures more stable. At Home Energy Save GB, we focus on correct density, even distribution and moisture control to ensure performance. Homeowners typically notice improved comfort levels and reduced reliance on heating systems. Over time, this translates into lower energy bills and a more energy efficient home.
Do you offer a free survey in Warrington?
Yes, we provide a completely free, no obligation borescope survey for homeowners across Warrington and surrounding areas. During the visit, one of our experienced surveyors will assess your walls internally using specialist equipment. We check cavity width, wall ties, existing insulation and any signs of moisture. We then provide clear, honest advice tailored to your property. At Home Energy Save GB, we believe proper assessment is the foundation of safe and effective insulation installation. We never recommend work unless it is suitable for your home.
Will cavity wall insulation cause damp problems?
When correctly assessed and installed, cavity wall insulation should not cause damp. Problems typically arise where insulation has been installed without proper checks or where cavities were already compromised. That is why we carry out a thorough borescope survey before any installation in Warrington properties. We check for debris, bridging issues and signs of moisture. At Home Energy Save GB, we follow industry best practice to ensure insulation performs as intended and does not introduce unnecessary risk to your home.
Is cavity wall insulation suitable for older properties in Warrington?
Many older properties in Warrington are suitable, but assessment is essential. Brick construction type, exposure to driving rain and cavity condition must all be evaluated. Homes near open areas or exposed elevations require particular attention. At Home Energy Save GB, our survey process ensures we fully understand your wall structure before making recommendations. We never assume suitability based purely on age. Our approach ensures insulation is only installed where it will perform safely and effectively.
Can cavity wall insulation help reduce mould growth?
While insulation itself does not treat mould, it can help reduce condensation related issues by stabilising internal wall temperatures. Cold walls are more prone to surface condensation, which can encourage mould growth. By reducing heat loss, cavity wall insulation can help minimise this risk. At Home Energy Save GB, we always assess ventilation and damp conditions during our survey to ensure insulation will contribute positively to your indoor environment.
