10 Questions to Ask Before Hiring a Window Installer (and How to Spot a Bad One)
Most “questions to ask a contractor” articles are generic enough to apply to any home-service purchase. These ten are specific to windows and doors, and each one has a real, checkable answer.
-
Are you licensed and insured in this state, specifically? A license number you can verify matters more than a claim of being “licensed and insured.” Aspen Bravo’s Tennessee license: [TN_LICENSE_NUMBER].
-
Is windows-and-doors your specialty, or one of several trades you do? Specialists install more volume and see more edge cases than a multi-trade remodeler.
-
What’s the workmanship warranty — separate from the manufacturer’s product warranty? Aspen Bravo backs installation labor with a [WARRANTY_YEARS]-year workmanship warranty, in addition to manufacturer glass/frame coverage.
-
Who actually performs the install — employees or subcontractors? [CONFIRM: Aspen Bravo’s crew model — direct employees vs. subs — before publishing this answer.]
-
What’s included in the quoted price, and what triggers a change order? Structural framing repairs discovered mid-install are the most common source of surprise costs — ask this up front.
-
Can I see recent local projects, not just stock photos? See our reviews and project gallery once live.
-
How do you handle disposal of the old windows? Should be included in the base quote, not a separate line item.
-
What financing options do you offer, and what’s the real APR? See financing for current options.
-
How long does a typical project take, start to finish? [CONFIRM: typical timeline by project size before publishing.]
-
What happens if I have a problem after installation? Ask specifically who to call and what the response-time expectation is — not just “we stand behind our work.”
Red Flags
Be cautious of: pressure to sign same-day for a “today only” discount, a quote with no line-item breakdown, and a contractor who can’t produce a license number on request.
