Non-Destructive Testing

Non-destructive Diagnostic Testing is used to detect moisture issues, such as water ingress, stucco and window leaks, excessive frost and condensation, air leakage, and energy efficiency.
Based on thousands of tests such as ASTM (American Society for Testing and Materials) and proprietary methods, we include methods such as infrared thermography, pressure differentials, blower door airtightness, HVAC static, and mechanical balancing, measurements for humidity and temperature, and data logging.

Building Envelope Consulting

The integrity of the building envelope is a vital part of the long-term performance of the building and has a direct impact on occupant health and comfort. Our team of Building Envelope Technicians are well equipped with building science knowledge and years of conducting site reviews and diagnostic testing, our engagement in a project is an assurance to the integrity of the built product.

The earlier we are engaged in the build project, the greater impact we have in helping the build team to create a structure that is both designed and constructed to perform safely over a long-time horizon. Our reports focus on the applicable building science aspects of the envelope, and our recommendations work with the build team to ensure compliance with the performance principles that need to be implemented to give the building the best chance at a long and problem free life.

Our specialty is on all manner of wood framed and residential construction techniques. Previously we have done on-site envelope consulting on:

Large Custom House Projects
Conventional Single Family Homes
Suited and Small Multi-Family Houses
Large, medium density housing projects featuring attached and stacked dwellings

Depending on the situation we have completed our third-party reports on new construction projects for:

Engaged Homeowners
Quality Conscious Builders and Trades
Home Warranty Providers

Pre-Construction Plan Review

Let our team of experienced Building Envelope Technicians bring our field experience to your project. Our services are more effective the earlier on in the process we are engaged on the project.

Once the construction drawings have been created for your project, partner with Qualistat Building Envelope Technicians to review the drawings and highlight risks with the proposed building that early on in the build process so the design can be tweaked before trades are on site and work is having to be removed. This service will also help to identify inconsistencies in the drawings package.

Airtightness & Blower Door Testing

Identifying air leakages are a key way to improving the comfort of a residential project. In Alberta, air leakages also lead to moisture issues given the cold climate conditions over the winter season. Even small leakages can cause moisture problems with the building envelope over the course of one or multiple years. Our pre-drywall blower door testing is geared specifically towards identifying air leakages that could impact occupant comfort or lead to moisture issues in the future. Our tests are completed during construction to maximize the ability to identify the air leakage areas. This timing also allows the build team the ability to, cost effectively, address the air leakage and seal it properly before finishes are installed.

Quantifying air leakages around and through a building envelope is also an important part in improving energy efficiency of the home. Our testing helps to calculate the total ACH (Air Changes per Hour) and the NLR (Naturalized Leakage Rate) for code compliance models. Our team is able to complete blower door testing that is compliant to a variety of standards including but not limited to:

USACE
CGSB
EnerGuide (Modified CGSB)
EN 13829 (Passive House International)

Infrared Thermography & Leak Detection

When combined with a blower door system, a thermal camera is a useful tool in identifying specific air leakage areas. Thermal imaging can help assist in determining the location of air leakages and the potential cause of moisture problems that arise from those air leakages. The best effectiveness of thermal imaging is when a significant temperature difference exists between the interior and exterior climates and a pressure can be created to induce the flow of air through the building envelope.

When dealing with climate conditions that do not have a significant temperature difference, other methods of leakage detection may be used. A theatrical smoke machine can be deployed to help identify air leakages between attached dwellings and manual air movement indicators can also be used in the right circumstances.

Forensic Investigation & Troubleshooting

When parts of a building are wet, and they shouldn’t be, that’s an indication to give Qualistat a call. Our diagnostic services aim to diagnose the issues that are at play in this particular situation which are leading to the water accumulations. Whether that water is appearing during or after rain storms or melt events, Qualistat will provide unbiased testing

services to help identify what is not working in your project. We have done thousands of non-destructive investigations all across Alberta investigating air leakages, attic rain situations and water ingress testing. Our reports are streamlined to focus on the aspect of the envelope that is causing the issue. As consultants, we aim only to identify the issues that are present in the project, we do not offer installation services. This gives our clients the assurance that we are working for them and we do not have ulterior motives for recommending one service or product over any other. In some situations, we are asked to come alongside the client to make sure the repairs are completed properly.

When necessary, our team of Building Envelope Technicians can conduct forensic investigations that can add support to legal proceedings. Reports from this level of service often heavily reference the building code and can help to identify issues that legal teams can press on in their cases.

Energy Modeling & Code Compliance (NECB / Step Code)

As energy codes become more demanding, navigating compliance requires both precision and experience. We provide performance-based energy modeling that aligns with NECB, Step Code, and regional requirements—ensuring projects meet regulatory standards while maintaining efficiency and constructability. Our team integrates seamlessly into the design process, delivering accurate models and practical guidance that help avoid delays and optimize outcomes.

Heat Loss / Heat Gain Calculations

Proper HVAC performance starts with accurate thermal load calculations. We provide detailed heat loss and heat gain analysis to ensure systems are correctly sized and aligned with actual building conditions. By combining rigorous methodology with real-world experience, we help eliminate inefficiencies, improve occupant comfort, and support long-term system performance. Our work gives both designers and contractors confidence that systems will perform as intended.

Training & Education (Builders, Trades, Designers)

Our experience in the construction industry, along with the breadth of the knowledge we have accumulated over the years is a great resource to deliver training modules to different groups of people. Whether taking advantage of our standard, rotating, training offerings or we need to develop a custom training package for a specific client group, Qualistat Building Performance Consultants bring the experience to deliver an insightful and engaging training to your project team.

Matterport Pre-Drywall 3D Capture

Matterport imaging of built products is a useful tool for keeping record of an interior space in the event future investigation or renovations are required. Matterport imaging creates a 3D image of the home that can be examined well after construction and it is constructed in such a way that accurate measurements can be taken from the image. When the imaging is completed at a pre-drywall stage of construction, the record will show the continuity of insulation and will give the viewer the ability to observe the placement and sizing of infrastructure inside the walls and ceiling such as electrical wires, plumbing pipes and duct runs.
