Façade Water Ingress

Façade water ingress occurs when rainwater penetrates the external building envelope and reaches areas that should remain protected.

Water ingress can originate from many different parts of a façade, making it important to establish the actual route and cause before carrying out remedial works.

What Causes Façade Water Ingress?

Common causes include:

  • Failed sealants
  • Defective joints
  • Damaged membranes
  • Failed flashings
  • Defective cladding
  • Poorly sealed windows
  • Curtain wall defects
  • Cracked render
  • Failed waterproofing
  • Defective interfaces
  • Damaged façade components
  • Inadequate drainage

Water Ingress Does Not Always Start Where It Appears

Water can travel through concealed parts of an external wall before becoming visible internally.

For example, a leak appearing around a window may originate from:

  • The window perimeter
  • Cladding above the opening
  • A membrane
  • A flashing
  • An adjacent joint
  • A cavity
  • Another façade interface

Finding the visible water stain therefore does not necessarily identify the source.

Investigating Façade Leaks

Our dedicated survey team can undertake façade condition surveys and targeted intrusive investigations where required.

Investigation may examine:

  • Cladding
  • Cavities
  • Membranes
  • Insulation
  • Windows
  • Curtain walling
  • Flashings
  • Joints
  • Interfaces
  • Balconies

Façade Water Ingress Remediation

Depending on the cause, remedial works can include:

  • Sealant replacement
  • Joint repairs
  • Membrane replacement
  • Flashing replacement
  • Cladding repairs
  • Window interface repairs
  • Render repairs
  • Waterproofing
  • Balcony waterproofing
  • Localised façade replacement
  • Complete façade remediation

See our Façade Waterproofing Services.

Persistent Water Ingress

Where previous repairs have failed to resolve a leak, further investigation may be necessary to establish whether the original diagnosis was correct.

A coordinated investigation and remediation strategy can prevent repeated reactive repairs.

From Investigation to Remediation

Trident Facades can coordinate:

Investigation → Diagnosis → Strategy → Design → Waterproofing & Remediation
