Quick summary
Here's the short version: in the general industry insights space, decisions come down to three things — outcome you want, condition of what you already have, and how much disruption you can tolerate during the project.
The deeper context
Most articles on this topic skip the nuance that actually matters. We'll cover the trade-offs you can't undo, the parts that are reversible, and the questions that should be answered before any quote.
What to ask any contractor before signing
- Will scope and price be in writing before mobilization?
- Who will be the lead on-site, and can I text them directly?
- What's the warranty, and what's NOT covered?
- Are subcontractors involved, and who manages them?
Common mistakes to avoid
Going with the cheapest quote without comparing scope.
Skipping the site walk — never accept a quote sight-unseen for non-trivial work.
Forgetting to confirm permits and inspection responsibility in writing.
