The Dorvin D. Leis Company, Inc. (DDL) is the largest mechanical contractor in the State of Hawaii. We are a full service mechanical contractor encompassing the entire spectrum of new construction for residential homes, condominiums, resorts, light commercial projects, high-rise complexes, schools, and hospitals across the Hawaiian Islands. Our construction has also included state, county, and federal projects including military facilities.

Our employees are the key to our success, and much like the local culture with its strong family ties, we must always nurture the relationships that support and strengthen our ohana.
