Cavity Wall Insulation
EcoHaus is a trusted, fully accredited installer of Cavity Wall Insulation, offering tailored solutions to homeowners across South East England. With over 20 years of experience in both residential and private projects, we provide dependable, high-quality insulation services designed to improve your property’s energy efficiency.
Cavity wall insulation is a proven method to significantly reduce heat loss by filling the air space between your property’s walls with high-performance insulation. This process enhances thermal performance, reduces energy consumption, and ultimately helps lower your heating bills. The first step in our process is conducting a free cavity survey. Using a Boroscope camera, we carefully inspect the interior of your walls to determine the most effective insulation solution.
Additionally, we can check if you qualify for a government grant under the Great British Insulation Scheme, which can help cover some or all of your insulation costs. Installation is quick and efficient, typically taking 2 to 5 hours depending on the size of your home. The process is carried out via the exterior walls, ensuring minimal disruption to your daily routine.
For added peace of mind all of our work comes with a 25-year guarantee, managed by Quality Mark Protection. Cavity wall insulation should never be attempted as a DIY project so trust the accredited experts at EcoHaus to ensure your insulation is installed safely and effectively, safeguarding your property for years to come.
