Remove window screens
Window screens are magnets for dirt, dust, and pollen. Screens diminish the natural light by up to 40%. There is never enough light inside a home. Natural light is a take-for-granted-amenity buyers seek. Screens also diffuse the view outside. We are selling that view. Buyers need to see clearly through your windows to appreciate the outside space they are buying.
I've yet to meet an attractive window screen. They are most definitely function over beauty. Removing your window screens makes your house more aesthetically pleasing. Wouldn't this house look more attractive with the screens removed?
Window screens should be stored in the attic or garage for the next owner. Buyers will see them and know they don't have to invest in buying them should they care to put them back.
My clients are always amazed at the difference removing window screens makes. Maybe you want to consider removing your screens even if your house isn't on the market!
