Based in Northampton, EWI Services Ltd. cover the whole of the Midlands the South East and East Anglia, installing External Wall Insulation and traditional exterior render solutions. The services we offer include:

External Wall Insulation (EWI)

An example of our work - housing regeneration in Milton KeynesExternal Wall Insulation (EWI) is applied to the exterior walls of a property in order to improve its energy efficiency. It is then covered in a series of layers of protective mesh, base-coat and top-coat render. All of the render solutions that we apply are silicone-based and are self-cleaning and not prone to cracking (unlike traditional sand/cement-based renders).

EWI is primarily targeted at properties of solid wall construction, although it can be used on almost any type of building (including those with cavity walls). It is a cost-effective solution that will dramatically improve interior comfort and reduce energy usage, but also transforms the external look of the property – increasing its value and ‘kerb-appeal’.

Over 35% of the energy required to heat a property escapes through its walls.

bostik-ewi-systemA correctly installed EWI system will reduce energy usage by approximately one-third. It can also help to prevent damp and mould from occurring on the inside a building, and can be used to remedy such situations should they already have occurred.

We are approved installers of a variety of BBA approved EWI systems, which are available in thousands of different colours and finishes. We offer a complete service, including removal and replacement of exterior fittings such as television aerials, satellite dishes and exterior lights. We also extend and replace components such as downpipes, guttering, boiler flues and window cills when installing External Wall Insulation. We always provide a cohesive solution and ensure that our customers are entirely happy with the end result.

We are a PAS 2030 accredited company, meaning that we are able to undertake External Wall Insulation work under government-led schemes such as the Energy Company Obligation (ECO). If eligible, our customers can access an ECO funding contribution which will assist with the cost of EWI installation – this is subject to a number of terms and conditions, and also requires a recent Energy Performance Certificate.

All our EWI work is covered by a 25 year insurance backed guarantee.

Domestic & Commercial Rendering

In certain cases it is not essential to insulate the exterior of a property, but its owners do wish to improve the way it looks and its resilience against adverse weather conditions. We are able to apply a wide range of different types of render and usually favour silicone-based renders (as we use for EWI) for their durability. However, in certain cases (e.g., for listed buildings or restoration projects) we also use a lime-based render that is more in-tune with historic building methods.

We can undertake all types of rendering contract, from small domestic jobs (e.g., a single wall of a property) through to large-scale housing and commercial regeneration projects. Please contact us if you have a project in mind that you would like to discuss.

Exterior Refurbishment

It’s often desirable to undertake other types of exterior refurbishment work whilst EWI installation or rendering is taking place – often because scaffolding will not need to be erected again. EWI Services offer an all-in-one solution that can include work such as:

  • De-commissioning and removing exterior fitments and features that are no longer required
  • Exterior decoration of fascias, soffits, windows and doors
  • Concealing exterior pipework, cables and other surface-mounted items
  • Replacing or extending window cills, downpipes and rainwater systems
  • Cleaning and repairing exterior feature stone and brick work, as well as lead work
  • Repairing and re-finishing areas below or around a damp course

For example projects where this type of work has been undertaken, please see our gallery of previous projects. All exterior refurbishment work is itemised on all our quotations and, where specified, can be shown in an artist’s impression of the proposed project.

Cladding, Roofline & Drainwater Systems

In the course of any EWI or rendering project, we are often asked to replace or extend existing downpipes, guttering, fascia boards, soffits, window and door cills and other exterior features.

We are also able to undertake other types of exterior cladding work. For domestic properties, customers sometimes request brick, stone or slate features to small areas of the outside of their property. In commercial projects, it is fairly common that some elements of the outside of a building will be clad using aluminum sheeting to give a contemporary look.

During any quotation and design meeting, our Project Managers can discuss a variety of different exterior finishes and fixtures with you. If you are looking for a certain type of finish, effect or design, then please contact us to discuss your ideas.

Internal Insulation & Plastering

We are also able to undertake all types of internal plastering and rendering contract. Furthermore, it may not be possible to insulate the exterior of a building either (e.g., it is listed, or there are constraints on its appearance). In these cases, we are able to install high-performance insulation to the inside walls of the property and then apply a plaster finish before decoration. We have also applied render finishes internally in certain cases – for example, in high-traffic areas where a robust and protective surface needs to be achieved.

If you have a project in mind that involves any of the above, we would be very happy to provide you with a detailed written quotation. You can make contact with us here in order to request this.
