Yes, 'responsiveness' is a major factor for me when choosing a tradesman. Or it would be, if it were possible in Spain to find any who stood out from the norm.
The rule seems to be: response to initial enquiry - prompt. Preparation of price quotation - slightly sluggish. Scheduling of possible start date for work - constant pestering required.
All it would take, you would think, in this part of the country where there are so many Scandinavians and Brits, would be for one small company to make punctuality their calling card - plaster it on their vans, and actually deliver - and they could clean up the lucrative expat home servicing market.
