Hello Celia
We have the same problem of being overcharged for very simple things, when a plumber comes into a house and sees there are computers, televisions and a big refirgerator you are in trouble they think you are very rich. But my husband has solved this problem, we have a janitor next door (nowadays janitors know plumbing, etc) so the janitor does most of the small things at the house and doesn`t charge much because he knows we are going to call him, besides I have a flat that I rent and I also take him there to fix the heater, he fixed very well a wood table and varnished it after, so this is a good trick and I don`t pay a fortune since then, he does plumbing very well, painting I think he also does, try to find someone that speaks Spanish for you and first give a janitor you trust a very small work and see what happens, if he is good you can give him some more work and always ask first him how much it is. I live in Monserrat if you live nearby I can contact you with our handyman, I have 9 year olds triplets so there is a lot to do at home always! My husband is an Accountant has no idea of fixing things at home and doesn`t like either
regards
There is always a solution!
I forgot to mention that we are overcharged even being locals!!!
