Is the professional verified?
Ask how the provider reviews professional suitability and assigns work. The answer should clearly describe the checks and coordination process actually in use.
Will I get the price in writing?
Any reputable provider will share a written quote before starting. Verbal estimates that change at billing time are the single most common complaint in this industry.
What warranty is offered?
Workmanship warranty separates confident providers from the rest. Thirty days on general work and ninety days on repairs is a reasonable benchmark.
Who do I contact if something goes wrong?
Look for a company-level support line rather than a single technician's personal number. Accountability matters most after the job is done.
