Since 1985

Father and Son. Forty Years of Systems.

Karel Peltram Sr. and Karel Peltram Jr. founded Peltram Plumbing shortly after coming to the United States. Four decades later, the company they built plumbs more production housing than almost anyone in the Seattle area, on a reputation measured in repeat contracts.

Built on repeat business: builders return project after project
