Founded in 1954, Winter Construction, Inc. has grown from a predominately residential builder into one of the largest commercial general contracting firms in northwestern Illinois. Building projects feature commercial, industrial and manufacturing - both new and remodeling - including banks, offices, churches, schools, pre-engineered buildings, with specialization in medical facilities and senior citizen retirement housing. Project size ranges from $20,000 to $20,000,000. Competitive bid and negotiated design/build work, for both the public and private sectors, constitute almost equal sources of annual sales, reflecting both the firms cost competitiveness and customer oriented management philosophy.
