The delays people tend to underestimate
In Hoddesdon, the quietest cost increases usually come from handling time: extra door codes, lift waits, stair repeats or a longer route from the van than expected. narrow hallways, stepped entrances and repeated turns through small porches or shared corridors often show up in exactly that way.
Because man-and-van work is shaped by practical time on site, those slowdowns matter more than many people expect.
How local layout creates extra effort
older terraces, maisonettes, family semis, modern flats and a scattering of shared-entry buildings can look easy from outside and still involve awkward corridors, shared halls or repeated loading stages. Add kerb space can tighten near busier central stretches, while newer developments sometimes rely on set-back bays rather than direct frontage, and a compact job can start to stretch.
The best way to avoid that is to describe the full handling route, not just the address line.
