ECS is an insulation, water, and energy consultancy with a difference. We don’t just advise; we get our hands dirty restoring Asturian stone architecture and the land it sits on.
We have no time for synthetic shortcuts. Instead, we use natural materials such as cork, hemp, wood fibre, clay and lime to enhance old stone and create breathable eco-envelopes. The result? Homes that are damp-free, low-carbon, and completely energy-autonomous.
Our work doesn’t stop there; we revive the surrounding land by clearing choked forests, overgrown orchards, and derelict gardens. Through clever water management, we transform these spaces into self-sustaining, irrigation-free growing areas.
We’re a no-nonsense, straight-talking restoration company that only installs what we’ve personally tested and lived with. No quick fixes. No stress. Just high-performance restoration.
Beyond our bespoke projects, we supply natural insulation, plasters, and off-grid hardware—including solar systems, water capture, low voltage heating, and water heaters—nationwide. We sell directly to constructors and self-builders and offer expert consulting on exactly how to spec, use and install our products to get the job done right.
To ensure we maintain this specialist focus, our partner BioReforma SL has taken over all operations in Andalucía. This allows us to focus exclusively on our passion, restoring the past for clients looking to escape the chaos of modern life and remain independent while living in total comfort in Northern Spain.
