Ask each reference the same open-ended questions about communication, budget changes, schedule reliability, workmanship, subcontractors, cleanup, warranty response, change orders, problems, and whether they would hire the contractor again. Request examples instead of simple yes-or-no answers, and pay close attention to how the contractor handled mistakes, delays, and disagreements.
Why reference calls matter
Photos and online reviews show the finished result, but a private conversation with a past client can reveal how the contractor operated throughout the project. References can describe whether calls were returned, estimates changed, subcontractors were supervised, the site stayed usable, and unresolved issues were handled responsibly.
Reference checks are not a guarantee. A contractor will usually provide clients who are willing to speak positively, and memories may be incomplete or subjective. Treat the calls as one part of due diligence alongside checking credentials, reviewing the contract, and confirming insurance. You can also check contractor license discrepancies online and verify important business information independently.
Before contacting references, compare the contractor’s proposed work with your own plans. A clearly defined remodeling scope of work for contractor quotes makes it easier to identify references with genuinely comparable projects.
How to prepare for the calls
- Ask for comparable projects. Look for references whose project type, size, age, and level of complexity resemble yours. A small bathroom refresh may not tell you much about a whole-house addition.
- Request permission to ask detailed questions. Start by explaining that you are evaluating the contractor and want an honest account, including difficulties. This often produces more useful answers than asking whether the person was satisfied.
- Use the same core questions with every reference. Consistent questions help you compare patterns instead of reacting to one especially enthusiastic or critical person.
- Ask for examples. If a reference says communication was good, ask how often the contractor provided updates, who gave them, and what happened when a decision was needed.
- Notice hesitation and qualifications. A qualified answer such as “the project went well, but the schedule slipped during inspections” is often more informative than unqualified praise.
Questions about communication
Communication problems can create confusion even when the physical work is acceptable. Ask questions that identify the process, not just the reference’s general impression.
- Who was your main contact during the project?
- How often did the contractor or project manager provide updates?
- Did the contractor respond within a reasonable time when you had a question?
- Were important decisions documented in writing?
- Did you understand what was happening next and who was responsible for each decision?
- How did the contractor handle disagreements or misunderstood instructions?
Follow up with: “Can you describe a time when communication broke down and what happened afterward?” A strong answer should explain both the problem and the recovery process. Also ask whether communication changed after the contract was signed. Some homeowners receive frequent attention during sales discussions but less contact once construction begins.
Questions about costs and change orders
Reference calls cannot prove that your estimate is accurate, but they can show how the contractor handled financial changes. Ask:
- Did the final cost differ from the original contract price?
- What caused the difference: owner-requested changes, concealed conditions, allowances, errors, or something else?
- Were you told about additional costs before the work was performed?
- Did you receive written change orders that described the price and schedule effect?
- Were allowances and material selections explained clearly?
- Did the contractor pressure you to approve unexpected costs quickly?
Ask the reference to separate legitimate changes from poor estimating. A remodel may uncover conditions that could not reasonably be confirmed before demolition, but the contractor should explain the issue, document the proposed solution, and give the homeowner an opportunity to approve or reject the change when the contract allows.
Pay attention to whether the reference can distinguish between a change they requested and a cost they believe the contractor should have anticipated. That distinction can reveal how carefully the contractor scopes work and manages expectations.
Questions about schedule reliability
Ask for both the promised timeline and the actual experience:
- What start date and completion date were originally discussed?
- When did work actually begin and finish?
- Were there periods when no one worked on the project?
- Were delays caused by materials, inspections, design decisions, subcontractors, weather, or the contractor’s scheduling?
- Did the contractor explain delays promptly and provide updated expectations?
- Did the project affect your ability to live in the home, use a bathroom, cook, park, or access other areas?
Do not treat every delay as evidence of poor management. Weather, permitting, inspections, product availability, and concealed conditions can affect a schedule. The more useful question is whether the contractor identified risks early, kept the homeowner informed, and revised the plan realistically instead of repeatedly promising an imminent finish.
Questions about workmanship and subcontractors
Ask the reference to evaluate the finished work after some time has passed, not only on the day the crew left.
- Are you satisfied with the quality of the finished work?
- Have any defects, leaks, cracks, sticking doors, finish failures, or other problems appeared since completion?
- Did the contractor perform a final walkthrough and create a punch list?
- Were corrections completed to your satisfaction?
- Which portions were performed by the contractor’s employees and which by subcontractors?
- Did subcontractors arrive when expected and treat the home respectfully?
- Did the general contractor supervise and coordinate the subcontractors effectively?
Ask whether the reference noticed differences in quality between trades. A general contractor may not personally perform electrical, plumbing, tile, or HVAC work, so supervision and coordination matter. You can also ask whether the contractor changed subcontractors during the project and how that affected the schedule or quality.
If a reference reports a subcontractor dispute, ask how the general contractor handled it. The relevant issue is not simply whether a subcontractor was replaced, but whether the homeowner received clear communication and whether the replacement work was completed properly.
Questions about cleanup and the impact on the home
Cleanup standards can affect daily life, safety, and the cost of protecting your belongings. Ask:
- How did the crew protect floors, furniture, landscaping, and occupied parts of the home?
- Were dust, debris, tools, and materials controlled at the end of each workday?
- Were temporary barriers, ventilation, or other containment methods used when appropriate?
- Did workers leave access paths, bathrooms, or cooking areas usable as promised?
- Who handled trash removal and final cleaning?
- Was the finished cleanup adequate, or did you have to hire someone or do substantial work yourself?
Ask for a specific example of the messiest phase and how the contractor addressed it. A reference may accept ordinary construction dust but still expect debris, nails, packaging, and tools to be removed safely and regularly.
Questions about problems and warranty response
The most revealing reference question may be what happened after the final payment. Ask:
- What problems appeared after completion?
- How did you contact the contractor about them?
- How quickly did the contractor respond?
- Did the contractor inspect the issue in person?
- Was the repair completed without unnecessary argument or delay?
- Did the contractor distinguish between a workmanship issue, a product failure, and normal maintenance?
- Are any issues still unresolved?
Ask to see the written warranty if the reference is comfortable sharing it, but do not assume another homeowner’s warranty terms match yours. Warranty coverage, exclusions, time limits, and procedures depend on the contract, product manufacturer, and applicable law. Review your own documents carefully and ask the contractor how warranty requests must be submitted.
A contractor does not need to have a perfect project history to be worth considering. What matters is whether problems were acknowledged, responsibility was explained honestly, and corrective work was completed in a reasonable manner.
How to judge the answers
| Reference response | What it may indicate | Useful follow-up |
|---|---|---|
| “There were a few changes, but each was documented.” | A structured change-order process | “Did you approve the price before the work began?” |
| “The project finished late, but we received regular updates.” | A delay that may have been managed responsibly | “What caused the delay, and how often did the schedule change?” |
| “The contractor fixed a problem after completion.” | Potentially good warranty follow-through | “How long did the response and repair take?” |
| “The crew was excellent, but the office was difficult to reach.” | Different performance levels within the company | “Who handled your concerns when the project manager was unavailable?” |
| “I would hire them again, but only for a smaller project.” | Qualified satisfaction or concerns about capacity | “What made you draw that distinction?” |
Look for repeated themes across references. One minor complaint may not be decisive, while the same concern appearing in several calls deserves serious attention. Also compare what references describe with what the contractor promised you. Differences may be reasonable, but they should be explained.
Final reference-checklist
Before you finish your due diligence, confirm that you have asked:
- How well did the contractor communicate?
- How often did the price change, and were changes documented?
- Was the schedule realistic and regularly updated?
- Was the workmanship satisfactory after the project had time to age?
- How were subcontractors selected, supervised, and coordinated?
- How well was the home protected and cleaned?
- How did the contractor respond to warranty issues?
- What problems occurred, and how were they resolved?
- What would the reference do differently next time?
- Would the reference hire the contractor again, and why?
For additional risk screening, verify liability coverage directly with the carrier rather than relying only on a certificate supplied by the contractor. This guide to verifying contractor liability insurance explains why direct confirmation can matter.
Frequently asked questions
How many contractor references should I call?
Call enough references to identify patterns, usually at least two or three comparable clients when the contractor can provide them. A recent project and an older completed project can reveal both current operations and long-term warranty response.
What if a contractor will only provide one reference?
Ask why, then request references from projects similar to yours. A limited list is not automatically disqualifying, but it gives you less information. Consider whether the contractor will allow a site visit, provide other verifiable project information, or explain how client privacy limits disclosure.
Should I ask references how much they paid?
You may ask whether the final cost was close to the contract price and what caused changes. Exact prices are often difficult to compare because project scope, finishes, location, timing, and allowances differ. Focus on estimating and change-order practices rather than treating another homeowner’s price as a quote for your project.
What is the most important question to ask a past client?
Ask, “What went wrong, and how did the contractor handle it?” Nearly every substantial remodel encounters decisions, delays, defects, or changes. The answer can show how the contractor communicates under pressure and whether the company takes responsibility for resolving problems.
