How to pay less
- • Get three written bids — spread between local bids on this project is routinely 25% or more.
- • Schedule in the off-season; Jacksonville contractors price peak demand higher.
- • Confirm the permit fee is itemized rather than marked up inside the labor line.
- • Verify the license at DBPR before paying a deposit; unlicensed work voids most claims.
