Questions before you pick a company
- Do you design this in-house, or do I need a separate designer before you can bid it?
- Which parts of this job do you do with your own crew, and which get subcontracted out?
- Can I see three bids from different companies built off the exact same plan?
- What does your written workmanship warranty cover, separate from anything the fixture manufacturers offer?
- How long have you held your current license, and does that match what the state's record shows?
- Who handles the permit, and is that cost already in this bid?
