Andrew's crew doesn't show up with a spray bottle and paper towels. We work with professional squeegees, extension poles for second-floor windows, and purified water systems that eliminate the mineral deposits responsible for spotting. Each window gets scrubbed, squeegeed, and detailed at the edges. Interior glass gets the same treatment -- we're not cutting corners on the inside because nobody sees us do it. Sills get wiped. Screens get removed, rinsed, and reinstalled. You'll notice the difference in how much natural light comes through when the job is finished. If your home hasn't had a professional cleaning in a few years, the first visit takes longer -- that's just the reality of built-up grime, hard water scale, and oxidation on the glass.
