Dragon Insulations Limited is an experienced insulation contractor specialising in cavity wall insulation, defective insulation extraction, cavity wall remediation and loft insulation.
From individual homes to large-scale programmes, our experienced teams understand the importance of getting insulation work right the first time.
We don't believe in a one-size-fits-all approach.
Every property and every project is different, which is why we take the time to understand the work required and provide the right solution for the building.
Our goal is simple:
Professional work. Honest advice. Reliable service. Quality results.
When insulation goes wrong, we know what to look for.
Defective or failed insulation can cause significant problems within a property.
Our experienced extraction teams deal with challenging cavity wall situations where existing insulation may have broken down, become contaminated, caused blockages or contributed to moisture-related issues.
We provide professional cavity wall extraction and associated remedial services, helping to remove unwanted material and restore the cavity where appropriate.
Our experience means we understand that extraction isn't simply about removing insulation.
It's about doing the job carefully, thoroughly, and professionally.
