The Post-Monsoon Exterior Checklist for Las Vegas Homes
Monsoon season in Las Vegas — July through mid-September — leaves behind more than dust. Mineral-heavy rain, storm debris, and wind-blown grit all bond to glass, gutters, and solar panels within days. Homeowners who tackle it in the first two weeks of September avoid nearly all of the etching, spotting, and output loss that show up by October. Here's the checklist we give our returning Real Clean Windows customers.
Why September matters
September has the two things you need for a clean-up window: cooler morning temps that keep water from flash-drying, and enough sun left in the year that fixing your solar panels still pays off. Wait until November and you've already lost 2 months of production.
The exterior walkthrough
- Walk the exterior at sunrise — angled light shows mineral spots and dust film that noon light hides.
- Note any windows showing white chalky patches (fresh hard-water spots) versus rainbow sheen (early etching).
- Check gutters for compacted dust and dead palm fronds after storm wind.
- Photograph the roof from ground level — you're looking for uneven color on the solar array (buildup) or debris caught between panels.
Windows and gutters
- Book an exterior-only window wash — interior is usually still clean from spring.
- Ask for gutters to be scooped and flushed before the next storm hits.
- If you see chalky spots on glass, request a hard-water assessment during the visit.
- Adjust any sprinkler heads that overspray onto the glass — the single biggest fix you can do yourself.
Solar panels and driveways
Solar output can drop 20% or more over a monsoon season. A deionized-water panel wash typically restores 90%+ of lost output within one billing cycle. Driveways and patios also pick up mineral staining and tracked-in debris during storms — a quick pressure wash after the last storm keeps stains from setting permanently.
When to bundle a pro visit
The bundle math works in your favor: a combined exterior window wash, gutter cleaning, and solar panel cleaning saves 10% off recurring service at Real Clean Windows, and the crew only has to make one trip. Most Las Vegas homeowners save $50–$150 versus booking each service separately.
