I thought it would be a good idea to have a thread where locals could post their experience of local services good or bad. Please only post from personal experience: Here's one to start with. Drainage Services Aguas Negras Tel 887 7337 or 842 3076 We had a problem with a blocked drain yesterday and called a local company pretty much at random. The company arrived promptly and carried out the work efficiently and cleanly (removing a chunk of concrete and a sealant bottle from the drain). In order to do this they had to dig a side trench and break the drain which they then repaired and filled in. Total cost of work was 650 pesos which I thought reasonable.
