About Code Blue Home Inspections

TREC #24069 | InterNACHI Certified Master Inspector | San Antonio, TX

At Code Blue Home Inspections, I believe a great inspection is about more than just identifying issues—it’s about giving clients the clarity and confidence they need to make one of the most important investments of their lives. My name is Nathan Cartwright, and I’m honored to serve the people of San Antonio and the surrounding South Texas communities with the same integrity and dedication that have guided me throughout my life.

​

A Career of Service

For the past 32 years, I’ve proudly served as a first responder, protecting and supporting my community. Alongside that public service, I earned my Texas Professional Inspector’s License and have continually expanded my skills through respected organizations including:

• RETS

• InterNACHI

• International Code Council (ICC)

• Exterior Design Institute (EDI)

• National Association of Water Treatment Specialists (NAWTS)

• Texas Department of Agriculture (TDA)

• Champions School of Real Estate

I am fully licensed by the Texas Real Estate Commission (TREC #24069) and committed to staying at the forefront of inspection standards and building science.

My Inspection Philosophy

Over the last three decades, I’ve dedicated myself to serving the public with focus, compassion, and a deep commitment to community. I bring that same dedication into every inspection I perform.
Integrity, commitment, and service are the core values that guide everything I do—whether I’m evaluating a historic home in downtown San Antonio or a brand-new build in the Hill Country.
