Our Approach

SERS offer an industry first whole life solution for the installation of external wall insulation.

Established in 1990 as an external wall insulation (EWI) and render company based in South Wales, SERS has grown and developed into a national specialist (offices in England, Scotland and Wales) in the design, supply and installation of EWI and façade solutions. We also offer a substantial repair solution for installs completed by other contractors, and a maintenance solution for installs completed by ourselves.

Extensive technical knowledge on solid walled and non-traditional archetypes makes us the leaders that we are today. We also provide a comprehensive failed cavity and cavity extraction solution.

With years of experience in the social housing sector, SERS have worked on thousands of homes across the country as both main contractor and preferred sub-contractor. From 20 house schemes to 500+ whole housing estates, SERS have vast experience working on both high and low rise properties of mixed tenure in the refurbishment sector.


Housing repairs must address immediate business and resident needs and also deliver intelligent stock investment. Fewer voids, reduced maintenance and SERS’ whole life solutions are attributable to achieving this.


Consistently rated as the most important indicator of their landlord’s commitment to them and their community, housing repairs directly affect residents and the impact they have upon lives can be significant.


Improved lives, an aesthetic transformation of properties in the area and increased community spirit all play a key part in creating better neighbourhoods for the future as a result of refurbishment.
