Welcome to Deeny Construction!


The high standards we have set for jobsite safety and quality are just as important today as when our company was founded by John Deeny in 1938.The other constant that has remained over three generations of family leadership is the outstanding group of individuals that have chosen to call Deeny Construction home. High integrity and a strong commitment to safety and excellence are characteristics that define every member of the Deeny team. We hope you enjoy our story!



Although our reputation is built upon tough Seattle sewer installations, our capabilities have been expanding.
