Services
Cornerstone has a philosophy of self-delivery, installing our energy efficiency measures using a combination of directly employed staff and self-employed individuals that work exclusively for our business wherever possible. Our people are highly skilled and committed to providing high quality energy efficiency solutions for our customers.
External Wall Insulation (EWI) is an extremely effective means of insulating solid wall properties to significantly reduce the amount of heat lost through the walls. The installation process involves fixing a layer of insulation material to the external walls of a property, and covering it with reinforcement and a special render in a range of decorative finishes.
Loft insulation involves the installation of insulating material between the joists of a loft floor to prevent the movement of heated air into the loft space and ultimately out through the roof. Heat will always flow from a warm area to a cold one and hot air rises. The colder it is outside, the faster heat from your home will escape into the surrounding air and up through the roof.
The term 'cladding' refers to components that are attached to the primary structure of a building to form non-structural, external surfaces - essentially forming a 'skin' around the building. Cladding can be made of materials including wood, metal, vinyl and a range of composites, and are often installed as prefabricated panels.
High performance through coloured render is an excellent option to improve the aesthetic of a domestic or commercial property. Render can completely change the look of a property, with customers able to choose from a broad range of smooth and textured decorative finishes. New render can replace old, tired or cracked existing coatings, as well as painted brickwork, removing the necessity to re-paint the surface every few years.

My cladding was fitted by Cornerstone, and I am absolutely delighted with the outcome. Professionals, always had a smile, and even when they looked tired, they never let that smile fade. Any questions I needed answered, were given with that smile! we were very, very lucky to get a grant.and it will certainly make our Home warmer in the winter. Excellent work!
