About from company website

Cornerstone is a main contractor specialising in the installation of energy efficiency measures and façade solutions. Founded in 2004 as a specialist in cladding and concrete repair, our expertise now extends to a broad range of home improvement solutions, from insulation to renewables. We work predominantly on domestic properties, for social landlords, local authorities, private landlords and individual home owners.

Our expertise extends to high and medium rise blocks, properties of non-traditional construction, park homes and non-domestic buildings. As a family business headquartered in East Anglia, we have grown organically to deliver contracts across the whole of mainland England. We are well known across the industry for our longstanding commitment to technical excellence and high standards of customer service.

We help our clients and customers access all available funding to ensure installations are affordable and offer a positive return on investment. Cornerstone is the ultimate safe pair of hands - directly delivered, technically compliant retrofit solutions for every property.
