We have vaulted windows in the LR, 28 ft high, and hard well water. Now way was I going that high on a ladder and I couldn't even get the "in reach" windows very clean, no matter what I tried. Clearview to the rescue! They did a fabulous job, I've never seen glass so clean before, and the price was reasonable for what they had to do, including moving dozens of plants off the window sills, pushing furniture out of the way, etc. I can't recommend Harold Cox and his company highly enough.
