About St Mary’s Window Cleaning Services


Window Cleaning Vancouver WA

Jeff St. Mary is the owner of St Mary’s Window Cleaning Services© and has been in business since 1990

Jeff St. Mary is the owner of St Mary’s Window Cleaning Services and has been serving the Portland OR, Vancouver WA Metro area since 1990. Jeff started St Mary’s Window Cleaning Services to work his way through college. The business prospered so he decided to continue the business. At first, he took care of the window cleaning, scheduling appointments, making calls and doing estimates. His solo venture worked so well that St Mary’s Window Cleaning Services quickly grew into a seven van fleet with up to 10 technicians and 2 office personnel, giving the company greater opportunity to serve residents and businesses and helping to keep their homes and offices bright and clean.

Before we hire:

  • We do a complete back ground check
  • Drug screening
  • We make sure the applicant has a good driving record
  • We also maintain a drug free work place
  • We place safety among our highest priorities
  • We use water fed poles as much as possible instead of ladders to reach high windows, as a safety precaution
  • We hold safety meetings on a regular basis to always find ways of improving

Let our qualified technicians work safely and securely in your home or office to provide you with professional cleaning. Along with window cleaning (inside and out) we also offer expertise in roof cleaning and the cleaning of decks, porches, and concrete. We offer siding cleaning services, gutter cleaning, and moss removal too. Think of us as your all-purpose window washing and exterior home cleaning service.

At St Mary’s Window Cleaning Services we do all the cleaning services work ourselves. No outsourcing to unknown contractors. This is one of our trust-building practices. We guarantee all of our work and promise both you and our contractors are safe. This commitment to doing a stellar job while staying true to our promise of safety has been the driving force in our success. People like our work, and they tell their friends!
