Fenestration Water Testing
We are an engineering firm in Ottawa providing fenestration water testing services
Who We Provide Fenestration Investigation Services To
Capacity Engineering provides Fenestration Investigation services to:
- Condominium corporations and boards
- Property managers
- Building owners and asset managers
- Developers managing existing buildings
- Legal and insurance teams requiring technical investigation support
Our work focuses on existing residential, commercial, and mixed-use buildings experiencing fenestration-related performance issues.
What Is Fenestration Investigation?
Fenestration Investigation involves the assessment and diagnosis of issues related to windows, curtain walls, storefronts, balcony doors, and other glazed assemblies. These systems are critical to a building’s weather resistance, energy efficiency, occupant comfort, and appearance.
When fenestration systems underperform or fail, consequences may include:
- Water leakage
- Air infiltration
- Condensation and fogging
- Glass breakage or stress cracking
- Seal and gasket deterioration
We conduct comprehensive investigations to determine the root cause of fenestration failures, not just visible symptoms.
Typical investigation areas include:
- Water leakage at windows, curtain walls, and balcony door interfaces
- Glass breakage or stress cracking caused by thermal, structural, or installation-related factors
- Condensation and fogging due to thermal bridging or seal failure
- Sealant and gasket degradation compromising air and water tightness
- Diagnostic water testing to confirm leakage pathways and performance deficiencies
Our investigations combine visual inspections, controlled testing, and performance analysis to develop accurate, defensible conclusions.
Why Do Clients Choose Us For Fenestration Investigations?
Specialized Fenestration Expertise
Fenestration investigation is a highly specialized discipline. Our engineers bring focused experience in window, curtain wall, and glazing-system performance.
National Leadership in Fenestration Water Testing
Our Principal Engineer serves as Co-Chair of the Fenestration Canada Committee on Water Testing of Fenestration, helping shape national best practices, testing protocols, and standards.
Standards-Based Testing & Analysis
We perform controlled water testing using calibrated spray rack systems in accordance with ASTM and AAMA standards, ensuring reliable and repeatable results.
Clear, Actionable Reporting
Our reports clearly outline findings, probable causes, and recommended corrective actions—supporting informed decision-making and efficient remediation.
Our Process For Fenestration Testing
1. Initial Review & Site Assessment
We review reported concerns, available documentation, and site conditions to define the investigation scope.
2. Visual Inspection & Documentation
We perform detailed inspections of fenestration components, interfaces, and installation details, supported by photo documentation.
3. Diagnostic Testing
Where required, we conduct controlled water testing using calibrated spray racks to confirm leakage sources and performance deficiencies.
4. Analysis & Reporting
We assess component performance, interface detailing, installation practices, and maintenance history to determine root causes and recommend solutions.
Why Fenestration Investigation Matters
Unresolved fenestration failures can result in:
- Repeated water damage and interior deterioration
- Increased maintenance and repair costs
- Reduced energy efficiency and occupant comfort
- Accelerated degradation of building-envelope components
- Disruption to occupants and operations
Fenestration investigations provide clarity, reduce uncertainty, and allow issues to be addressed effectively and permanently.
