Master Builders of Iowa strives to be the essential resource for Iowa’s construction industry and a valuable component of that effort are the companies who support MBI’s programs and events. Through the exclusive Essential Partners recognition program, MBI strives to recognize our industry supporters, while adding value to those companies’ sponsorship dollars who take leadership roles in sponsoring MBI events and educational opportunities. Companies that are considered MBI’s Essential Partners have contributed over $3,000 in sponsorships to the Master Builders of Iowa in the past year. These companies are an important part of MBI’s success and we couldn’t do it without them!

MBI’s Essential Partners are profiled on the MBI website, with direct access to their listings from the homepage. They also receive a full-page company profile in an edition of InsideMBI, the association’s quarterly news magazine. These profiles are very exclusive offerings since MBI does not offer advertising on the website, nor in the magazine.

Clive / Strawberry Point, IA

Seedorff Masonry (SMI) and Architectural Wall Systems (AWS) have combined over 90 years of experience to create an intentional approach to the delivery of the building envelope.

With early involvement as a member of the design and construction team, every detail from engineering through construction receives the attention it deserves to maximize quality, economy, and performance. Systems analysis, including thermal modeling, ensures that the air barrier, insulation and cladding systems are designed, coordinated and executed to create high-performing vertical exterior envelopes. The AWS/SMI team utilizes their financial stability, operational efficiency, state of the art technology, global supply chain, and project-centric philosophy to provide unique value to all members of the project team.

SMI and AWS have longstanding traditions of excellence based on a commitment to Safety, Quality, and Performance. Join them in their mission to “Push the Envelope” and pursuit of a vision to “Build Better.”
