External Wall Insulation (EWI) Specialists in Sussex

​

At T&B Plastering Services, we supply and install high-quality External Wall Insulation (EWI) systems across Brighton, Hove, Peacehaven, Newhaven, Saltdean, Lewes, Seaford and the wider Sussex area.

As a Baumit Approved Installer, we are trained to fit EWI systems to the highest standard, using premium insulation boards and silicone render finishes. Our approved status also allows us to provide manufacturer-backed warranties, giving homeowners long-term peace of mind.

EWI is one of the best ways to improve your home’s energy efficiency, reduce heat loss and modernise the exterior appearance — all in one installation.

​

What Is External Wall Insulation (EWI)?

External Wall Insulation involves fixing insulation boards to the outside of your property, then applying a reinforced base coat and a breathable, weatherproof render system such as silicone render.

This creates a warmer, more energy-efficient home while giving your exterior a fresh, modern look.

​

Benefits of EWI

Significantly improves insulation and reduces heat loss.

✔ Modern, Fresh Appearance

✔ Protects Against Damp & Weathering
Stops penetrating damp and shields the building from harsh weather.

✔ Breathable & Long-Lasting
Ideal for older buildings and coastal properties.

✔ Reduces Carbon Footprint
Improves energy performance and efficiency.

✔ Baumit System Warranties Available
As approved installers, we can offer manufacturer-backed guarantees on Baumit EWI systems.

✔ Noise Reduction
Adds sound insulation — especially useful near roads or busy areas.

 

Our EWI Installation Process

  1. Survey & Preparation

  2. Insulation Board Installation
    High-performance insulation boards (EPS, Mineral Wool, PIR depending on requirements) are securely fixed to the exterior walls.

  3. Reinforced Base Coat
    A Baumit-approved base coat with embedded mesh provides strength and flexibility.

  4. Primer & Silicone Render Finish
    We apply your chosen render finish — available in hundreds of colours.

  5. Detailing & Finishing Touches
    All edges, corners and openings are neatly finished for a clean, sharp look.

  6. Final Clean & System Warranty Registration
    We leave your property tidy and provide optional warranty documentation.
