How Many Times a Year Do Professional Window Cleaners Recommend Service?

Ask this question broadly and you'll get a fairly consistent answer across the professional window cleaning industry: 2–4 times a year. That's a reasonable starting benchmark — but it's built as an average across all kinds of climates, which means it needs adjustment for a place like Kamloops that sits outside the "average" on both dryness and hard water.
The General Industry Standard, and Why It Exists
Industry-Standard vs. Kamloops-Adjusted Recommendation
| Property Type | General Industry Standard | Kamloops-Adjusted Recommendation |
|---|---|---|
| Average home | 2x/year | 2x/year |
| High sun exposure / south-facing | 3x/year | 3–4x/year (hard water compounds faster here) |
| Commercial storefront | Monthly-quaterly | Monthly–quarterly (unchanged — high visibility standard) |
| Near heavy irrigation/sprinklers | Not typically flagged separately | Flagged separately — every 3 months |
Where Kamloops Diverges From the National Average
The industry-standard number typically doesn't account for hard water mineral content, because it's built across a mix of climates where that's not universally relevant. In Kamloops, it is — irrigation-heavy landscaping combined with mineral-rich water is common enough that we treat it as its own frequency-adjusting factor rather than folding it into a generic "sun exposure" bucket.

Why This Matters for Choosing a Provider
If a company quotes you a cleaning frequency without asking about sun exposure, sprinkler proximity, or your specific street/dust conditions, that's worth noting — a Kamloops-appropriate recommendation should look different from a generic national default, not identical to it.

The general industry standard is 2–4 times a year, depending on property type. For Kamloops specifically, this should be adjusted upward for homes with high sun exposure or sprinkler/irrigation proximity, due to hard water mineral buildup that's more common in this climate.
