The founder-era period buildings in the Südstadt, Nippes and Ehrenfeld need constant renovation, new heating systems and bathrooms. The market is huge — but so is the number of firms courting the same jobs. Whoever wants the planned job has to make their references visible.
In an emergency, by contrast, seconds count: a burst pipe in an old building, a heating failure in winter. Whoever ranks at the top of search then, with a reachable number and a clear Cologne service area, gets the call — not the firm that only appears in a directory.
