Quality Assurance Inspections

Better construction quality. Better building performance.

Professional quality assurance inspections

RunBrook provides quality assurance inspections to help builders, developers, contractors, and property owners verify that construction work is completed correctly, consistently, and in alignment with project requirements. Our inspection services help identify issues early, reduce costly rework, support code compliance, and improve overall building performance.

Whether your project includes a single residence, a multifamily community, a production home development, or a commercial building, our team provides reliable third-party inspection support designed to keep your project moving forward.

What are quality assurance inspections?

Quality assurance inspections are third-party field evaluations used to review construction details, building systems, and installation quality during key phases of a project. These inspections are designed to confirm that work has been completed properly and to identify items that may need correction before the project advances.

RunBrook’s inspection team reviews relevant areas of the building based on the project scope, construction phase, and inspection requirements. This may include building envelope details, insulation installation, air sealing, duct systems, ventilation components, mechanical systems, and other energy-related construction items.

Our goal is to provide clear, practical feedback that helps construction teams correct issues quickly and maintain project quality.

What RunBrook inspects:

  • The building envelope separates conditioned indoor space from the outdoors. RunBrook inspects key envelope details to help identify gaps, penetrations, missing components, or installation issues that can affect comfort, efficiency, moisture control, and overall building performance.

    Common inspection areas include:

    • Exterior wall assemblies

    • Attic and ceiling transitions

    • Floor and wall connections

    • Window and door openings

    • Penetrations through the envelope

    • Garage-to-living-space separations

    • Mechanical, plumbing, and electrical openings

  • Air sealing is one of the most important parts of building performance. Small gaps and cracks can allow conditioned air to escape and outside air to enter, leading to higher energy costs, comfort issues, and failed performance testing.

    RunBrook reviews air sealing details before they are hidden by drywall or finishes, helping project teams correct issues early.

    Common inspection areas include:

    • Top plates and bottom plates

    • Plumbing and electrical penetrations

    • Recessed lighting areas

    • Attic access points

    • Duct and chase penetrations

    • Framing gaps and bypasses

    • Window and door rough openings

  • A thermal bypass occurs when air moves around or through insulation, reducing its effectiveness. Even if insulation is installed, gaps, compression, or missing air barriers can allow heat transfer and reduce overall building performance.

    RunBrook’s thermal bypass inspections help verify that insulation and air barriers are properly aligned and continuous throughout the building. This type of inspection occurs once all insulation is installed but before drywall installation.

    Common inspection areas include:

    • Kneewalls

    • Dropped ceilings

    • Soffits

    • Attic transitions

    • Behind tubs and showers

    • Fireplace surrounds

    • Stair framing

    • Bonus rooms over garages

    • Cantilevered floors

Why these inspections matter


Catch issues before they become expensive

Quality assurance inspections help identify construction issues before they are covered by drywall, insulation, or finishes. This makes corrections faster, easier, and more cost-effective.

  • Verify that the building envelope, insulation, and air sealing details are installed correctly.

  • Identify issues before blower door testing, duct leakage testing, energy inspections, or final inspections.

  • Catch problems early while they are still easy to correct.

  • Reduce drafts, moisture concerns, hot and cold spots, and HVAC performance issues.

When should quality assurance inspections be scheduled?

RunBrook’s quality assurance inspections are most valuable before important systems are covered or before performance testing is performed.
