Building Envelope Leakage
Investigation of recurring leakage through facades, roofs and junctions, starting with the records and observations rather than a repeat of the last repair.
Quick Answer
Leakage rarely has a single obvious cause. An envelope investigation brings together where and when water appears, what has been repaired before and what can be seen on the building, so that the next step is chosen on evidence.
Seasonal rainfall and exposure vary by region and by building. The scope is set from your leakage records and photographs, and any repair approach follows an understanding of the cause.
Who This Is For
- - Building owners and occupiers
- - Residents' and owners' associations
- - Facility managers
- - Developers handling defect reports
When It Is Needed
- - Leakage recurring in rainy seasons
- - Previous repairs have not held
- - Stains, damp or efflorescence appear
- - Before a refurbishment of the envelope
What Problems This Service Solves
Water follows the easiest path, which may be far from where it appears. Careful investigation links symptoms to likely sources before repair work is chosen.
Facade & Joint Defects
Open joints, cracked render and failed sealants are recorded and compared with where leakage is reported.
Window & Opening Junctions
Interfaces between frames and walls are common entry points. Their condition is checked against the leakage locations.
Roof & Parapet Details
Upstands, drainage and flashings are reviewed as part of the water path rather than in isolation.
Failed or Partial Repairs
Earlier treatments may have moved the problem rather than solved it. Records of past repairs help avoid repeating them.
Moisture in the Structure
Where moisture is suspected inside walls or slabs, targeted checks help show its extent.
Incomplete Leakage History
Dates, rain events and locations are often scattered. The investigation consolidates them into a usable record.
The Investigation Process
Leakage Record
Gather locations, dates, photographs and previous repairs
Site Survey
Inspect envelope elements and record observed defects
Targeted Checks
Use moisture checks or further tests where they help
Analysis
Link observations to likely water paths
Report
Findings, limitations and options for remediation
Methods & Techniques
Techniques are used only where they help answer the question, and results are read alongside the leakage history.
Visual Envelope Survey
Systematic review of facade, roof and junction details.
Moisture Mapping
Indicates where moisture is present in walls and slabs.
Infrared Thermography
May help identify moisture patterns where conditions suit.
Water Testing
Controlled wetting of suspect details to check a suspected path.
Material Sampling
Laboratory checks where material condition is in question.
Record Review
Drawings, specifications and past repair information.

Why New Nordic
Defined Scope
Each assignment starts with a clear question, an agreed scope and a stated reporting format.
Site-Specific Approach
Location, building use and available records shape the work, not assumptions from another market.
Evidence-Led Findings
Observations are recorded with their location and context, with limitations stated plainly.
One Connected Team
Planning, design, supervision and review can be discussed together, with responsibilities agreed from the outset.

Frequently Asked
Can I request an assessment of recurring leakage?
Yes. Share the affected locations, when leakage occurs, photographs and details of previous repairs. This helps define an appropriate investigation scope.
Why not simply repeat the earlier repair?
If the cause was not identified, the same treatment may fail again. An investigation aims to understand the issue first, so the repair is chosen on evidence.
Is leakage always seasonal?
Not always. Some leakage follows heavy rain, while other sources are linked to drainage, plumbing or condensation. Your records help distinguish them.
Do you carry out the repairs?
We assess and report, and can advise on remediation options. Execution is agreed separately and carried out by the appointed contractor.
What should I prepare?
Photographs with dates, a note of when the leakage appears, drawings if available and a summary of earlier repairs are all helpful.
