Customer Reviews
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.

Worried that heat could be escaping from your Blackburn home or finding your heating bills increasing during the colder months? Home Energy Save GB offers a free borescope survey for homeowners across Blackburn and the surrounding areas, helping you identify whether your property may benefit from cavity wall insulation.
As part of the survey, our experienced team completes a thorough inspection of the property, carefully reviewing the structure and condition of the cavity walls to establish whether insulation can be installed safely and effectively.

The Importance of a Borescope Survey
With our FREE borescope survey in Blackburn, we carry out a detailed inspection to confirm that your property is suitable for cavity wall insulation and that it will perform effectively in the types of homes commonly found across the local area.
During the survey, we will:
- Assess whether your home is suitable for cavity wall insulation and whether the construction of the property allows insulation to be installed safely and effectively.
- 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 Blackburn
Defective or saturated cavity wall insulation can trap moisture within the walls of your Blackburn home and may lead to damp related issues developing inside the property.
These problems can arise where insulation has been incorrectly installed in the past or where moisture has gradually built up within the cavity over time. Homes in Blackburn are regularly exposed to high levels of rainfall and cooler conditions, particularly in areas closer to the Pennines and surrounding open landscapes, which can increase the likelihood of moisture related issues forming within cavity walls.
Cavity Wall Insulation Extraction
Older or poorly installed cavity wall insulation can lead to a variety of issues within your Blackburn home, including damp patches forming on internal walls, mould growth in affected areas and a clear decline in overall energy efficiency.
Solution: Our cavity wall insulation extraction service in Blackburn safely removes defective or waterlogged insulation materials from within the cavity walls. This process reinstates the cavity so it can perform as intended, allowing trapped moisture to escape and helping to prevent further damp related issues from developing within the property.
