North Carolina, Commercial Building Envelope Testing

We deliver building envelope testing in North Carolina for GCs, commissioning firms, building owners, and design teams who need commercial-grade results. Our field execution follows ASTM E779 as the primary standard and ASTM E1827 where project conditions or engineer specifications require it. This commercial construction market spans everything from Charlotte-metro office and mixed-use projects to institutional builds across the state, and our testing protocols are built to match that range. We mobilize statewide and coordinate directly around your construction schedule.

Commercial Envelope Testing Across North Carolina's Project Types

Our building envelope testing in North Carolina supports project teams from pre-closeout verification through AHJ documentation. We show up knowing the protocol, execute it correctly, and deliver reports formatted for Cx workflows or direct code-official submission. We’re equipped to perform ASTM E779 whole-building air leakage testing on medical office buildings, government facilities, K-12 and higher-education campuses, and large mixed-use commercial projects across North Carolina. Our protocols, equipment, and standards knowledge are built for these project types.

ASTM E779 and E1827 for Commercial Projects

Our commercial air leakage testing in North Carolina follows ASTM E779 for whole-building fan pressurization testing and ASTM E1827 when orifice blower door conditions apply. The building envelope test result is reported in ACH75 or leakage per envelope area, giving your team the exact metric your spec requires. Results are formatted for direct use in commissioning reports and code compliance packages.

Statewide Commercial Reach

Our commercial blower door testing in North Carolina covers the Charlotte metro and extends statewide. We’ve built our scheduling around busy commercial construction timelines, and we coordinate with GC and Cx teams to minimize disruption. Whole-building air leakage testing in Charlotte and across NC is performed using the same ASTM-compliant procedures, regardless of project location.

ASTM-Compliant Reporting for Cx Review

Our ASTM E779 testing in NC delivers documentation your commissioning authority and building owner can rely on. ACH75, CFM50, and normalized leakage outputs are included. Our air barrier testing in NC reports are structured to clear owner review and code official inspection on the first submission, reducing the back-and-forth that delays final closeout.

I had the pleasure of observing Josh, Robert and Daniel recently during a Field QA trip, and was blown away by their process-oriented and quality-focused approach towards servicing their clients. Air Tight Solutions has a bright future ahead of them, and any builder or homeowner looking for a HERS Rating Company in their service area should look no further!

I had a great experience with Airtight Solutions for my home energy inspection. Their team was extremely knowledgeable and professional from start to finish. They performed a blower door test, duct leakage testing, and a full HERS rating, and took the time to clearly explain what everything meant for my home’s efficiency. If you’re building a new home or need energy code compliance testing, I highly recommend Airtight Solutions. They understand building science, insulation, air sealing, and HVAC performance better than anyone I’ve worked with in the Upstate SC area. The report was detailed, accurate, and delivered quickly. Top choice for home energy audits, RESNET HERS ratings, and blower door testing in South Carolina.

He shows up when he says he will, communicates clearly, and delivers accurate results without slowing down the job. His process is efficient, his reports are prompt, and he keeps things straightforward for our team and inspectors.

I recently did a full renovation on one of my homes, as I called in for my final inspection, I was informed that the required blower test was overlooked! We were already behind schedule so this is the last thing we needed! I called Air Tight Solutions and they were able to work us into the schedule before the next inspection date. It was a big save! Josh and his team did a great job from start to finish. I highly recommend them for your compliance testing needs.

Called Josh after finding Air Tight Solutions via a Google search to help with an issue I was having getting a permit. My issue was not in their typical scope but he adapted to find a solution within 48 hours. Pricing was extremely reasonable and while many companies just say “no I can’t do that”, he chose to find a solution. Highly recommend! -Local Residential Builder
