A contractor's portfolio shows their best work, curated and photographed well. It doesn't show how they handle a delayed shipment, an unexpected structural issue behind a wall, or a disagreement about scope halfway through a project — and those are the moments that actually determine whether a renovation goes well. A short list of specific questions during the interview reveals far more than another look through their photos.
Ask about a project that went wrong
Every experienced contractor has had a project hit a real problem — a permit delay, a material backorder, an unexpected issue found during demolition. Asking directly how they handled one, and listening for whether the answer includes clear communication and a specific resolution, tells you more about how they'll handle your inevitable surprise than any number of smooth, on-schedule projects in their portfolio.
Ask exactly how change orders work
Nearly every renovation includes some scope change along the way. Ask specifically how the contractor documents and prices changes — is it a written change order with a signature before work proceeds, or a verbal agreement settled at the end. Contractors without a clear, consistent answer to this question are the ones most likely to produce a final bill with surprises in it.
Ask who is actually on-site day to day
The person who gives the estimate and the person who runs the daily work are often different people, particularly at larger firms. Ask directly who your point of contact will be once the project starts, and how often they're actually present versus the crew being unsupervised. This matters more than almost any other single factor in how smoothly a project runs.
Check references by asking one specific question
When calling references, skip the generic "were you happy with them" and ask instead: "was there anything you'd do differently if you did this project again?" It's a harder question to deflect with a vague positive answer, and the specific concerns it surfaces — a communication gap, a scheduling issue — are exactly the details a general reference check misses.
