Remediation

Diagnostics-Led EWI Remediation

Failed or underperforming EWI systems need careful diagnosis before repair. We identify the likely cause, explain the risk and advise on the right remediation route.

Failed EWI systems need diagnosis, not guesswork.

Cracking, water ingress, delamination and poor detailing are symptoms. The important question is why they are happening and whether the system can be locally repaired or needs more significant intervention.

Our remediation work is built around investigation first, then targeted repair. This helps avoid superficial patching that fails again later.

Common defects

Render crackingMovement, poor basecoat, weak reinforcement or defective detailing can all contribute.
Water ingressOften linked to reveals, sills, rooflines, penetrations or damaged render surfaces.
DelaminationSeparation between layers can indicate installation failure, moisture problems or unsuitable preparation.
Thermal bridgingMissing or poorly installed insulation details can undermine performance and comfort.
Poor original workmanshipIncorrect fixings, incomplete mesh, failed beads or weak junction detailing.

Remediation starts by identifying why the system failed.

Cracks, staining or blown render are symptoms. The underlying cause may be poor detailing, fixing failure, moisture ingress, substrate movement or an unsuitable original specification.

Moisture pathways

We look closely at sills, reveals, copings, plinths and penetrations where water can track behind the system and cause ongoing damage.

Local or full repair

Not every defect requires full replacement. We assess whether targeted reinstatement is suitable or whether larger system correction is the safer route.

Finish compatibility

Where possible, repairs are planned to blend with the existing render. Where matching is unlikely, we explain this before work begins.

Repair with the standard of a new installation

Our remediation work is carried out to TrustMark-aligned and PAS 2030/2035-informed standards, so repair decisions consider system integrity, detailing, moisture management and long-term performance.

  • Defect investigation before quoting
  • Clear explanation of cause and remedy
  • Targeted repair where appropriate
  • Full reinstatement where local repair is not enough

Investigate. Explain. Repair correctly.

The goal is not to hide the issue. The goal is to understand it and repair it properly.

01

Visual inspection

We inspect the defect pattern, junctions, affected areas and any visible risk points.

02

Cause review

We assess whether the issue is localised damage, detailing failure, moisture-related or system-wide.

03

Repair route

You get a clear recommended route: local repair, partial reinstatement or broader replacement.

04

Remedial work

Defective areas are repaired with appropriate materials and detailing to reduce repeat failure risk.

Remediation questions

Can you repair EWI installed by another contractor?+
Yes. Many remediation enquiries involve systems installed by others. We assess the current condition and advise on the correct route.
Can you match the existing render?+
We aim to match colour and texture as closely as reasonably possible, but older finishes can weather differently. We will be honest about what is achievable.
Do all defects require full replacement?+
No. Some issues can be repaired locally. Others indicate broader failure. The inspection determines the correct option.
Is remediation higher value than normal repair work?+
Often, yes. Correct EWI remediation requires specialist understanding of system build-up, moisture risk and detailing.
