I'm Mason, known around town as "Mason the Window Cleaner." I'm based in Leander and Bee Cave is a regular route for me. Most of what I get called out for here comes down to one thing: the water.
Both Bee Cave and the wider Hill Country pull from limestone sources, but Bee Cave properties tend to face heavier hard water etching than most, because so many homes run well-water irrigation or sit on private water districts like WCID 17. Sprinklers hitting the lower panes day after day leave thick calcium deposits, and those need chemical remediation and steel wool rather than a standard squeegee pass. If your home is off the main lines, washing windows with untreated well water straight from an outdoor spigot will leave heavy mineral spotting the moment it dries, which is why I bring purified deionized water to every job.
The second thing is dust. Bee Cave is still actively expanding, so construction dust from new builds mixes with oak and cedar pollen and forms a gritty paste on exterior glass and in the window tracks. Developments like Falconhead, Lake Pointe and Spanish Oaks also hold owners to real exterior consistency standards, including maintenance schedules and window tint and screen compliance, so keeping the glass and screens right is not optional here.
