The news: The Las Vegas Sun reported July 20 that monsoon storms will bring flash-flood risk across Southern Nevada through the week, with moisture expected to hang around for days. It caps a stretch that already mixed 109° heat with near-daily storm chances across the valley.

What it means: this is the wrong month to pay for exterior cleaning
Here is advice a cleaning company does not usually volunteer: hold off on window cleaning, solar panel cleaning, and pressure washing projects until monsoon season winds down. Desert storm rain is not clean water — it carries dust and minerals, so freshly washed glass hard-water spots after one cell, cleaned solar panels re-film within days, and washed concrete takes the next round of silt right back. Money spent on exterior cleaning in late July is money the next storm undoes.
Where your cleaning attention should go during storm weeks is inside: entry matting on both sides of every door, drains cleared at entries and garage ramps, a wet-floor protocol your day staff actually knows, and tracked-in silt removed from hard floors quickly — grit works like sandpaper under foot traffic, and it will dull a finished floor faster than anything else on this list.
The move: protect interiors now, book the reset for when the season breaks
When the monsoon pattern ends — typically by late September — one thorough exterior cleanup beats three washes that fought the weather all summer. That is when the season’s accumulated dirt, silt lines, and staining come off your concrete, glass, and panels in a single pass and stay off. Post-monsoon slots go fast because every building in the valley hits the same moment at once, so this is the week to get on the schedule, not clean.
