What is the markup? 6. **Which warranty covers what, and for how long?** Ask for the warranty document itself, and whether it transfers if you sell the house. 7. **Who does the work?** Which parts are done by your own crew and which by subcontractors, and are the subcontractors licensed? 8. **Can I see your license and a current insurance certificate?** Check the license yourself on the state's license lookup, and ask the insurer to send the certificate. 9. **What happens if I cancel?** Before permits, after permits and after work starts: what do you keep, and what do you refund? 10. **When could you start, and what delays the finish?** Get the start date in writing, and ask how weather and inspections are handled. ## Section 7 Frequently asked questions Which indoor air quality systems companies in Largo are included here?
