Deep Retrofit and Construction Services

Sea Box Energy has teamed up with leading construction company, Heffernan and Galvin Construction, to offer full project managed building services for your retrofit project.


Deep Retrofit and Renovation Solutions

A deep retrofit involves a substantial upgrade of a building so that it moves closer to zero energy requirements or a significant reduction in the energy required within a building. Deep retrofitting looks at the entire building and a bespoke solution is designed for each house which considers all aspects such as building fabric, air tightness, ventilation and renewable energy sources.

Whether you’ve lived in your home for decades or you’re only there a few years, there will come a time when you’ll seriously think about renovating your home and home improvements. Renovation and construction work as well as home improvements can add serious value to your property.

Maybe your family has grown and you need more space, or the kids have left the nest, and you have space to yourself, finally. Maybe you’re thinking about future-proofing for your old(er) years, or maybe you just fancy a change and want to create something different without moving house.
