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 Coventry
Failed or saturated cavity wall insulation can retain moisture within the cavity and contribute to damp issues inside your Coventry home.
Problems commonly occur where insulation has been poorly installed, where cavities were not properly checked before fitting, or where long term exposure to heavy rainfall has allowed water to enter the wall structure. Using specialist extraction equipment, our experienced team carefully removes the defective material, ensuring the cavity is fully cleared and given time to dry before any remedial treatment or new insulation is installed.
Cavity Wall Insulation Extraction
Old or poorly installed cavity wall insulation can lead to damp issues, mould growth and a noticeable drop in energy efficiency within your home.
Solution: Our cavity wall insulation extraction service in Coventry removes failed or saturated insulation thoroughly and safely, ensuring the cavity is completely cleared. This allows the wall structure to breathe properly, reduces the risk of ongoing moisture problems and restores the cavity so it can perform as it should, helping to protect the integrity of your property.

How much could I save on energy bills with cavity wall insulation in Coventry?
Savings depend on property size, existing insulation levels and heating habits. However, uninsulated cavity walls can account for a significant proportion of heat loss. In Coventry, where winter temperatures regularly drop and many properties rely on gas central heating, insulation can noticeably reduce heating demand. At Home Energy Save GB, we calculate potential savings during your assessment and explain realistic expectations. Most homeowners experience improved heat retention, reduced boiler run times and more consistent indoor temperatures, which translates into measurable savings over time.
Will cavity wall insulation cause damp in my home?
Correctly installed cavity wall insulation should not cause damp. Problems usually arise when cavities were not properly inspected beforehand or when inappropriate materials were used. At Home Energy Save GB, we always complete a full borescope survey in Coventry properties before installation. We check for debris, mortar bridges and signs of moisture. If a property is exposed or shows existing damp issues, we address those first. Our approach is preventative and evidence based, ensuring insulation enhances performance rather than compromising the building fabric.
What is a borescope survey and why is it necessary?
A borescope survey allows us to inspect inside your cavity walls using specialist camera equipment. In Coventry, where housing stock ranges from older brick terraces to post war builds, cavity condition can vary widely. The survey enables us to check for obstructions, damp, wall tie condition and correct cavity width. At Home Energy Save GB, we never install insulation without this step. It protects your home and ensures the insulation will perform effectively and safely over the long term.
Can you remove old cavity wall insulation if it is causing problems?
Yes. We provide specialist cavity wall insulation extraction services across Coventry. Using professional extraction equipment, we remove failed or waterlogged insulation safely and thoroughly. At Home Energy Save GB, we ensure the cavity is fully cleared and allowed to dry before recommending any further action. This prevents ongoing moisture retention and protects the structure of your home. Extraction is a technical process and must be carried out carefully to avoid damaging brickwork or internal finishes.
What guarantees do you offer on cavity wall insulation in Coventry?
At Home Energy Save GB, our cavity wall insulation installations are backed by guarantees of up to 25 years. This provides long term reassurance that the materials and workmanship meet strict quality standards. We explain all guarantee terms clearly before work begins. Our focus is on correct installation from the outset, as this is what ensures durability. Coventry homeowners can proceed with confidence knowing the work is protected and professionally delivered.
