Uniform ES offers manufacturers and building officials another,
we believe better, option as an evaluator of building products.


Since 1926, IAPMO has been a leader in codes and standards development. As a company within The IAPMO Group, Uniform Evaluation Services is built upon an 95-year-old foundation of experience, expertise, and quality.

Uniform ES is accredited by the American National Standards Institute (ANSI) per the ISO/IEC Standard 17065, Conformity assessment — Requirements for bodies certifying products, processes, and services . This means that building products, materials and designs bearing the Uniform ES mark of conformity are trusted for their conformity and workmanship by contractors, inspectors, architects, engineers, officials, and Authorities Having Jurisdiction.

Uniform Evaluation Services provides assurance for yourself, end users and building regulators that the code- which sets the bar for building component acceptability- has been satisfied. We ask the tough questions, and when we get answers, we issue a Uniform Evaluation Report that tells the report holder and the reader that someone with the right expertise asked the right questions and got the right answers.

Our Assurance Program benefits everyone. The code official saves time by using our detailed review, freeing staff to perform other tasks. Manufacturers do not have to answer the same questions over and over again. Consumers are assured that the product has been evaluated against the building code enforced in the places they work and live.

It's a thorough process, but not onerous. See for yourself.

Built on the reputation of the foremost source of uniform codes and standards, Uniform Evaluation Services is the agency of choice for building officials everywhere. Our expertise starts with our in-house dedicated staff of engineering professionals. The leadership’s credentials and experience in building product evaluation is unparalleled in the industry; Jerry Carrier, Richard Beck, Brian Gerber, Barry Johnson, Adam Barefoot, Woods McRoy, Rafael Donado, and Michael O'Reardon have collectively over 160 years' experience evaluation building products.

For more than 85 years, our group of companies have been involved in product recognition in building product listings and evaluation reports. We work hard to bring drive, determination, and great customer service into the building product evaluation arena.

Uniform ES is the smart option for your company’s evaluation needs. Building products, materials, and designs bearing the Uniform ES Mark of Conformity are trusted by contractors, inspectors, building officials, and Authorities Having Jurisdiction as having met the most rigorous standards and are in full compliance with applicable codes.
• Fair and Balanced                                 

• Evaluating products on a level playing field


Evaluation Reports generated by Uniform ES represent the highest degree of integrity in showing compliance with the International Building Code (IBC) and International Residential Code (IRC).

Don’t just take our word for it, though — listen to what our customers have said about Uniform Evaluation Services:

"We have utilized IAPMO for nearly 2 years, and are very impressed with the services they provide, and the professionalism of their team.  It was very evident from the beginning that they were going to work side-by-side with us. Their amazing staff is very experienced, and helped us with every step in the certification process."

"IAPMO and VELUX have a good relationship with both parties working together to maintain the Skylight product certifications in place.  The audits are not only necessary for maintaining the certifications, but we have found IAPMO’s thoroughness and experience to be helpful to ensure our VELUX Quality Management System is kept in good order.  The Greenwood facility has been ISO 9001 certified since 1999 with systems in place that have been improved for many years.  In 2019, we expanded with another facility in Wells, Maine and in 2022, our production expanded to Sparks, Nevada.  These areas had to be brought up to speed with new ISO certifications sought and achieved in 2022.  It has been crucial to have good partners to ensure the products and our quality systems reflect the same high quality standard expected in the Greenwood facility.  We are thankful for partnerships like IAPMO to help us achieve and ensure the expected quality from VELUX products.  Our VELUX audit group with the help of IAPMO auditor, Neal Wilkinson, have partnered to make this happen in all three facilities.  We appreciate IAPMO and the expertise of their audit program to ensure continuous improvement of our VELUX Quality Management System."

“Neal and the IAPMO team have done an excellent job helping our team improve our products and our overall business. Answering technical and industry questions, and serving as a trusted source of advice to me and my team. They are always professional and helpful.”
"In 2011 Foam laminates Of Vermont decided to have our sips tested for their structural capabilities and to obtain our code listing.  Neal Wilkinson came to our facility, he explained the process, pricing, and gave us a timeline for the final report. Neal also worked with us on our quality service verification program which is still in place today through IAPMO. We highly recommend Neal for his knowledge of the industry, testing procedures and passion for the services that he represents."

"Wasn't Supposed To Be Like This: When we think of Code and Code reports, it’s not supposed to be fun or enjoyable to deal with. When we hear words like ‘Evaluation Services’ and ‘Uniform Services’ that sounds quite regimented and restrictive; it’s not supposed the be made easy and personable. When we deal with Engineers and ‘think-y’ people, it’s not supposed to be engaging and fun conversation. When we deal with a ‘bureaucracy’ it’s not supposed to consist of personalized service and quick responses. When dealing with an establishment service we are expected to PAY and WAIT; it’s not supposed to be affordable and fast. When we get a random text or email from an evaluation service we are supposed to cringe; it’s not supposed to be a courtesy check-in or just saying hello. When dealing with that other establishment, we continually get passed off and reassigned to another person; we’re not supposed to have a ‘concierge’ service. Thank you for assembling a Best in Class Team to make these processes much more enjoyable."


"IAPMO UES plays an important role facilitating product evaluation processes and provides a service by issuing an informed third-party opinion that a new or alternative structural product meets the intent of the codes, which is essential to the building industry and the public’s wellbeing."
