Start with the exact work
A repair quote and a full door replacement are different purchases. Confirm whether the quote includes diagnosis, parts, labor, removal and any follow-up work. Ask how additional work would be approved if it is discovered during the visit.
Compare door construction
For a replacement, record the size, panel construction, insulation, windows, finish and hardware. A similar appearance does not necessarily mean the same product or performance.
Check opener compatibility
Confirm whether the existing opener can remain, whether a new opener is included and which controls or connected features come with it. Ask whether electrical or network preparation is your responsibility.
Get warranty terms in writing
Product and workmanship coverage may be different. Ask what each covers, its duration, exclusions and who to contact for service. Confirm disposal and cleanup, payment timing and the expected installation process.
