Ways to lower your Chicago price
- Leave the ceiling open and painted to save on drywall and access issues.
- Finish in phases — rough-in everything now, finish rooms later.
- Collect three written bids on an identical scope — spreads of 20–40% are normal.
- Book in the off-season and stay flexible on the start date to save 5–15%.
- Bundle nearby work into one mobilization so you only pay setup and travel once.
- Ask what the contractor would change to cut 10% without hurting durability.
