The exterior of a house is a bit like makeup on a woman — it can improve the appearance, but it doesn’t solve the problem from within.

Render alone can simply cover up imperfections, whereas a full insulation system is real care for the home: it improves comfort, protects the walls, reduces heat loss, and creates a result that is not just “for show”. It’s not masking — it’s looking after the home from the ground up.

We have been working with for many years, and their support has been part of our journey across our projects.

We are pleased that we can continue to grow together and work towards the same goal — delivering high-quality external wall insulation and render systems that help make homes in the UK warmer, better protected and compliant with current building regulations.

This brochure is a great way to showcase our work, the materials we use, and the full system behind every project we complete.

Strong partnership, trusted materials and proper workmanship — that’s what makes the difference.

In collaboration with Pride Developments on the Job Centre project, using materials.

One of our previous projects, showing how much difference a properly finished facade can make. This building needed a fresh, clean and professional finish — and the transformation speaks for itself.

Good preparation, the right materials and attention to detail can completely change the appearance of a commercial property.

A clean facade is not only about the look — it also helps protect the building and creates a much stronger first impression.

Clean, modern and built to last.

This project is a great example of how the right render finish can completely transform the look of a property.

A fresh facade, sharp details and a clean colour combination give the house a much more modern and high-quality appearance — while also helping to protect the building for years to come.

👋🏻 Hi , Meet US!

We are Sebastian and Sebastian Directors of EWI Specialist Ltd — a company we run with a strong focus on solid workmanship, quality, and trust.

EWI Specialist is a Hertfordshire-based company with over 21 years of experience in external wall insulation and rendering, and we have built that experience consistently through years of work in the industry.

From the very beginning, what mattered most to us was doing things properly and delivering results that not only look good, but also genuinely perform and stand the test of time.

Our company continues to grow through a clear focus on key services: external wall insulation, rendering outside walls, and brick slip cladding, which allows us to create solutions tailored to different types of buildings and projects.

What sets us apart is our emphasis on quality workmanship, trust, and high standards, because these are the values on which we want to build the EWI Specialist name.

Responsibility for what we do is also very important to us.
That is why our clients always receive the highest quality products, warranties, and certificates, as well as building condition assessments and other related services.

For us, EWI Specialist is not just a company, but the result of many years of experience, commitment, and standards that we aim to uphold in every project.
