I have arrived to the conclusion that it is absolutely necessary to seal my windows with mosquito nets, something which I knew but tried to avoid. Now, I could try and do it myself, but I prefer the professional work and I am fed up with DIY and the like lately.
I suppose the easiest will be getting the exact measures of half the window and then find somebody who will make a frame out of wood or aluminium covered with plastic mesh to fit in. I remember seeing some ironmongery which offered this service, but I don't remember now exactly where.
What do you recommend? I know some turnkey contractors would do it, but I fear them as prohibitely expensive for a simple job like this one.
