Charlotte Envelope Testing That Keeps Projects on Schedule

As your building envelope testing partner in Charlotte, NC, we verify that your commercial envelope meets spec before finish work hides the barrier. Our crews run fan-pressurization diagnostics, document every reading, and format results for the commissioning file. You get faster deficiency detection, fewer surprises at handoff, and a building that performs the way your design team intended. That keeps your schedule tight and your owner confident.

Standards-Correct Testing Under ASTM Methods

About Us

Air Tight Solutions was built on a simple observation: builders were spending too much time untangling energy compliance and not enough time building. We stepped in to fix that. Our background in residential new construction gave us a strong technical foundation, and we’ve carried that precision into commercial and multifamily work across the Southeast. We’ve run ASTM E779 tests on commercial bank branches, and we partner with GCs and Cx firms that need accurate, submission-ready data without back-and-forth. You always know what we’ve done and what we bring to your scope.

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.

There is no one better to hire for your code compliance testing than Air Tight Solutions.

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
