Building Envelope Inspections and Leak Detection

We use our education, experience, and state-of-the-art equipment to find building envelope failures.

Part Nine Performance offers comprehensive home efficiency surveys to identify and resolve issues related to poor design, faulty workmanship, or material failure. Our inspections cover insulation, infiltration, and the interaction between the building envelope and the HVAC system. By addressing these issues, we enhance energy efficiency, indoor air quality, and reduce energy consumption and costs. Our inspection includes infrared technology, professional moisture readers, and wall scanners to detect moisture up to 4" within walls. We provide a precise non-destructive moisture reading, building envelope assessment, detailed report, and repair quote.

Building Envelope Inspections 

We evaluate the crucial components of your home's envelope, including the roof, attic, foundation, siding, windows, and doors. Through comprehensive inspections, we identify and address issues related to insulation, air infiltration, and moisture intrusion. Our goal is to optimize energy efficiency, improve indoor air quality, and reduce energy costs. We can provide detailed reports and repair quotes so you'll have the information and solutions you need to enhance the performance and durability of your home's building envelope.

Leak Detection

We specialize in identifying and resolving leaks in residential properties, ensuring the integrity of your home and protecting it from water damage. With our advanced technology and expertise, we can accurately detect hidden leaks within walls, roofs, and foundations. Our non-invasive methods, including infrared technology and moisture readers, allow us to pinpoint the source of the leak without causing unnecessary damage. Whether you're experiencing water intrusion or suspect a hidden leak, our team is here to provide a thorough inspection, detailed assessment, and effective solutions to keep your home safe and dry.


Thermal Imaging

Our advanced thermal imaging technology allows us to uncover hidden issues within your property's infrastructure, including insulation gaps, air leaks, electrical faults, and moisture problems. By capturing infrared images, we can detect temperature variations and anomalies, providing valuable insights into potential energy inefficiencies and areas of concern. With our comprehensive thermal imaging reports, you'll have a clear understanding of your home's thermal performance and be equipped to make informed decisions for energy optimization and cost savings.

Roof and Attic

Roofs and attics are the most common areas in a home to have problems. Some of the common problems we see are:

  • Ice Damming

  • Attic Rain

  • Mould Growth and Condensation

  • Poor Ventilation

  • Bulk Water Leaks

  • Missing or Thin Inslation

  • Exhaust Fan Duct Leaks

We perform attic and roof inspections to best determine the cause of problems and recommend solutions for repair. If  desired, we then offer services to manage all necessary repairs.

Basements, Foundations, and Crawlspaces

Below-grade areas in a home are places that are very prone to moisture problems. Some of the common problems we see are:

  • Foundation Cracks

  • Moisture and Mould

  • Radon Gas

  • Window Well Leaks

  • Lot Grading and Drainage Issues

  • Cold and Drafty Basements

  • Deteriorated Wood Foundations and Framing

  • Poor Ventilation

We perform basement inspections to best determine the cause of problems and recommend solutions for repair. If  desired, we then offer services to manage all necessary repairs.
