Renovations almost always cost more than expected. Even with careful planning, hidden expenses can pop up and blow the budget.
Common surprise costs include:
Structural issues: Hidden problems like weak beams, leaks, or foundation cracks.
Electrical & plumbing: Old wiring or pipes that must be replaced once walls are opened.
Permits & inspections: Paperwork fees that many homeowners forget to budget for.
Waste removal: Dumpsters, hauling, and clean-up can add up quickly.
Delays: Extra labor costs if the project takes longer than planned.
Bottom line: The most surprising renovation costs are the ones you can’t see at first. Always add a 10–20% “just in case” cushion
to your budget.
