The cumulative impact of these hidden costs can reach 20-35% of the base project cost.
Smart budgeting in Naperville means adding a 15-20% contingency buffer on top of your best estimate. This isn't pessimism — it's the most consistent advice from IL contractors with 10+ years of experience. Projects that come in under budget are rare; projects that exceed it are the norm.
