Robert is fantastic! He returns phone calls, was pretty quick to fit us in. We have a LOT of windows and several glass doors.(About 40 windows and 11 glass doors. ) The first day he showed up right on time and worked straight through. Removed all screens and washed them, washed inside and outside of windows and doors . Our house isn't easy...3 stories on the back side and a solid one floor on the waterside. Robert was very polite, interesting to talk to. He came back to finish the basement and garage windows as the first day it got to dark to finish. I would highly recommend this company, Robert and will definitely have him back again!

Robert did a wonderful job. He was on time and worked through the day. We now have beautiful clear windows and clean screens. He was very meticulous and was attentive to every detail. We highly recommend him.

Window Cleaning Preparation and Assessment

Not all windows require the same cleaning approach. Before we begin window cleaning, we assess your window type, condition, accessibility, and level of buildup.

Our proper preparation includes:

  • Window type identification
  • Accessibility assessment
  • Frame and seal condition evaluation
  • Screen inspection
  • Streak-free product selection
  • Safety planning for upper-level windows

Different window types require different cleaning techniques. Bay windows, skylights, and specialty glass need specialized approaches, while coastal properties face unique challenges from salt spray.

In many cases, our regular window cleaning prevents glass etching and seal degradation that lead to costly window replacement.
