Concierge Service in Commercial, Residential, and Restoration Construction.



Your Premier Concierge Service in Construction

Uniplex Construction company represents a unique blend of multiple long-standing companies and their combined talents and Principles. Founded in 1979, Uniplex Inc began as a commercial tenant improvement contractor serving the downtown Seattle corridor and the greater Eastside. In 2013, Joe Schwab and Joe Schwab, Sr., owners of HCS Construction Services, purchased Uniplex, Inc to supplement their existing company and improve their commercial construction division. HCS Construction Services, also founded in 1979, had its niche in the greater Seattle area as a custom home builder and award-winning residential remodeler.

The two companies operated independently to serve both residential and commercial clients until their merger in 2015 when Uniplex Inc officially acquired HCS Construction Services and became what is now Uniplex Construction. Since 2015, Uniplex has expanded its team and knowledge pool with the addition of talent from CWC Construction and Madison Master Builders Inc.

Uniplex is a relationship-based construction company that enters into all of its projects with a team-oriented approach. Its Project Managers collaborate with clients and the design team from the concept phase through project completion, delivering a superior product with exceptional value. Uniplex also partners with an extensive network of trade partners to bring the best solutions, recommendations, and values to their clients.

Today, Uniplex Construction has a diverse, experienced, and highly accomplished team whose Principals and Senior Project Managers alone have over 150 years of construction experience. This, combined with a seasoned team of Project Managers, Project Engineers, Administrative staff, Superintendents, and superior production crews make Uniplex one of the most well-rounded and talented companies in the greater Seattle area.
