External wall insulation, rendering systems and retrofit upgrades delivered with a practical understanding of system build-up, detailing and long-term performance.
External wall insulation is a full system, not a decorative finish. The substrate, fixing method, insulation type, detailing, mesh, basecoat and render all need to work together.
We support installation work with a practical understanding of EWI systems, site conditions and the details that often decide whether a job performs properly over time.
A strong EWI installation is not just about getting insulation onto the wall. It depends on preparation, sequencing, junction detailing and using the correct components as a full system.
We check surface condition, existing coatings, friability, flatness and areas that may need stabilising before the system build-up begins.
Windows, doors, sills, verges, plinths and roofline junctions are where many systems fail. These areas are considered early, not treated as afterthoughts.
Render texture, colour, exposure and maintenance expectations are discussed so the finished system suits both the building and the client’s priorities.
Our installation work is delivered to TrustMark-aligned and PAS 2030/2035-informed standards, with particular focus on detailing, moisture risk, thermal continuity and system manufacturer requirements.
A controlled approach keeps the project clear, practical and less stressful.
We review wall type, condition, access, openings, details and suitability before advising on the correct route.
The system, finish, insulation thickness and key details are clarified before work starts.
Boarding, fixing, meshing, basecoat and finishing are completed with attention to the details that matter.
Final checks, site clean-up and clear aftercare guidance once works are complete.
