Building users opinion

See assessments on the ad type into Google: "660876 ABRITEL" heading assessments and also says "ABRITEL 868572"

A tourist told me one day in 2011: "Sir with your exemplary achievement you should be recognized of public utility."

If you had to do it again?

Choose by tenders more skilled craftsmen while limiting their number (+ plumber + electrician + heating renewables)
Look for examples of local authorities (unfortunately. .. Examples are scarce ...)
