Where hidden costs usually come from
Most hidden costs in Eastleigh are really hidden time. Short-stay bays, resident controls and busier town-centre kerbs near the rail corridor, slow key handover and flats with managed access, newer estates with allocated bays and longer walks from overflow parking are the patterns that usually push a small move past the first estimate.
What prevents the drift
Share the true loading route early, confirm when keys are available and be clear about any stairs, gates, lifts or internal distance. A short job stays cheaper when none of those details are discovered on the doorstep.
