FAQ
Window cleaning questions
How much does window cleaning cost?
Every home is different, so we give a free custom quote instead of a one-size price. It depends on how many windows you have, how high they are, how dirty they are, and which add-ons you want. Send us a few details and photos through the quote form and we'll get back to you with a price within one business day.
Do you clean the inside and outside of windows?
Yes. Exterior window cleaning is our specialty and where most of the dirt is, but we also clean interior glass. You can choose exterior only, interior only, or both.
What is pure-water (water-fed pole) window cleaning?
We filter water until it has no minerals in it, then scrub the glass and frames with a soft brush on a long pole and rinse with that pure water. Because there are no minerals or soap left behind, the glass dries clear with no spots. It lets us clean second and third-floor windows from the ground, which is safer for us and easier on your home.
Do you use ladders?
Only when the job needs it. Pure water handles most exteriors, especially high windows. For very dirty glass, detailed panes or windows a pole can't reach well, we use ladders and traditional squeegee work so the job gets done right.
Will my windows have streaks or spots?
No. Pure water dries spot-free, and anything we clean by hand is detailed with a squeegee and microfiber. If you see a streak we missed, tell us and we'll come back and fix it.
Do I need to be home for my window cleaning?
Not for exterior cleaning, as long as we can get to the windows (unlocked gates, pets inside). For interior cleaning someone needs to be home to let us in.
