Lake Oswego commercial janitorial services

Originally founded in the 1850’s and intended to be home to a sawmill, today Lake Oswego is one of Portland’s best-known and most affluent suburbs.

Today, you’ll find banks, hospitals, upscale offices and other commercial buildings in Lake Oswego.

Since 1961, Cascade Building Services has provided a variety of commercial cleaning services to banks, condominium complexes, offices and other buildings in Lake Oswego.
