4 Things You Should Know Before Hiring a Window Cleaner

  • Are the workers employees or subcontractors?
  • Have the workers undergone criminal background checks?
  • Have the workers undergone drug screening?
  • Does the company offer a guarantee?

These are important questions to ask so you know who is in your home. Some companies hire subcontractors who do not meet the above standards. If damage, an accident or theft occurs, you could be left with the financial responsibility of repairs, doctor’s bills or replacement of stolen items. All workers at St. Mary’s Services are employees – not subcontractors. Before qualifying for a job, each applicant must prove a good driving history, agree to a full criminal background check and drug screening. We also maintain a drug free work place.

The St Mary’s Difference

Window Cleaning Vancouver WA Professionals

Windows are cleaned using AquaClean system or by hand. The system is a five filter purification system that removes 99% of minerals from the water. Pure water is brushed on the window, effectively removing dirt without the need for harsh chemicals, and ensuring your window cleaning is best you can get. For those places where the water fed pole is not conducive to cleaning windows, such as the inside of your home or office, we use an environmentally-friendly, mild cleaning solution, as well as cloths and squeegees to remove the dirt from. Dirt is removed from the tracks using cloths, brushes and vacuums. Frames are wiped down as well.

We start on the inside or the outside, which ever will accommodate your schedule. We clean the inside and the outside of the glass and remove screens so we can clean the area behind the screen. We also remove storm windows so we can clean between the two sets of glass.

The end result is sparkling clean windows you’ll be proud of!
