About Assured Precision

---

At Assured Precision, we provide reliable code compliance testing services, including blower door and duct leakage testing, to help builders and project teams meet local, state, and national energy code requirements with confidence. Our experienced technicians deliver accurate, repeatable testing while keeping projects on schedule and minimizing disruptions on site.

We take a practical, field-focused approach to testing—coordinating closely with construction teams to perform tests at the appropriate stages and ensuring results are clearly documented and inspection-ready. By identifying air leakage and duct performance issues early, we help reduce failed inspections, limit re-testing, and avoid costly delays that can impact project timelines and final approvals.

Our team works directly with builders, HVAC contractors, and site supervisors to communicate results clearly and provide straightforward guidance when improvements are needed. Each test is completed in accordance with applicable energy codes and program requirements, with clear, code-ready reports delivered promptly. The result is smoother inspections, fewer callbacks, and confidence that every home meets required performance standards before final sign-off.

What is a HERS Rating?

A Home Energy Rating System (HERS) Rating is a nationally recognized measurement of a home’s energy efficiency. It provides builders, homeowners, and code officials with a clear, data-driven way to evaluate how efficiently a home is designed and constructed.

The process begins with a review of the home’s construction plans. Using accredited energy-modeling software, a certified Home Energy Rater analyzes the design to generate a projected (pre-construction) HERS Index score. This score estimates how the home is expected to perform once built. During this phase, the rater works closely with the builder to identify cost-effective energy-efficiency strategies needed to meet the desired performance level.

As construction progresses and once the home is complete, the rater conducts on-site inspections and performance testing, which typically include:

• Blower door testing to measure air leakage through the building envelope
   
• Duct leakage testing to evaluate the efficiency of the HVAC distribution system
   

The results of these tests, combined with verified on-site data, are used to finalize the home’s official HERS Index score. This score confirms the home’s energy performance, supports code compliance and program certifications, and helps ensure long-term comfort, efficiency, and quality.

What is NGBS?

The National Green Building Standard® (NGBS) is an ANSI-approved, third-party certification program that provides a flexible, practical, and affordable path to verifying green construction practices. It applies to single-family homes, multifamily buildings, remodeling projects, and land development, making it one of the most versatile green building programs available.

Projects can earn one of four certification levels—Bronze, Silver, Gold, or Emerald—allowing builders and developers to select a performance target that aligns with their goals, budget, and market.

The certification process must be overseen by an NGBS Green Verifier or NGBS Master Green Verifier, accredited by Home Innovation Research Labs.

Verifiers conduct required inspections, complete the scoring documentation, and manage the administrative aspects of certification. Bringing a verifier on board early in the project—ideally before drywall installation—adds significant value, helping identify efficiencies, reduce costs, and improve overall building performance from the start.

At Assured Precision, we guide clients through the NGBS process with clarity, accuracy, and dependable support—helping you build greener, smarter, and with confidence.

Reveal hidden energy losses with precision infrared thermography.  

Our advanced thermal imaging technology allows us to evaluate the building envelope in detail, identifying air leakage pathways, missing or compressed insulation, and thermal bridging—issues that are often invisible during a standard visual inspection.

We translate complex thermal data into clear, actionable guidance.   Our assessments help builders, designers, and property owners improve energy performance, enhance occupant comfort, and address concerns early—before they escalate into costly repairs. The result is a more efficient, durable building and the confidence that your project meets both quality and performance expectations

At Assured Precision, we assess indoor air quality and identify potentially harmful mold growth to help maintain a safe, healthy living environment. Our mold inspection and testing services are designed to detect conditions that may contribute to mold development, locate visible and hidden growth, and evaluate airborne mold levels when concerns arise.

We provide clear findings and practical guidance so homeowners, builders, and property managers can address moisture issues, reduce health risks, and protect the long-term integrity of the building. Early detection supports healthier indoor environments, improved occupant comfort, and peace of mind.

 Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil and rock. It can enter a home through cracks and openings in the foundation and is invisible and odorless, making testing the only way to determine exposure levels.

At Assured Precision, we provide professional radon testing with fast turnaround, clear reporting, and guidance you can trust.

Long-term exposure to elevated radon levels is a leading cause of lung cancer among non-smokers, which is why testing is strongly recommended—especially during real estate transactions.

We don’t just provide results—we help you understand them so you can make informed decisions with confidence.
