Most WC’s try to get customers on a twice per year basis. Tho it’s not unusual to do 3 per year. I have a couple like that. I have one that I do once a month but this is a rarity. Screens are just something you have to deal with. Many WC’s do a basic brushing or wipe included in the wc price while others charge for screen cleaning and may include some special cleaners and sealers. newer homes tend to have casement windows with screens on the inside of the house. In this case you’d only clean them if you were also doing the interiors and they usually only need a quick wipe.
So far I haven’t noticed too many companies using WFP for residentials unless they are new homes and especially 3 story town homes. So yes, there will be ladder work.
Some, like myself, have small commercial storefront routes as well as doing residential. Storefronts can be done year round. Just add some antifreeze washer fluid to your mix. I also shovel snow for some of my WC clients. I’ll be looking at some other addons or totally unrelated things to keep me busy this next year. I don’t mind cleaning windows in the winter, it’s just that it’s a hard sell for residentials and like last year, most days had too much snow to do the work safely.
Anymore questions just fire away.
