Contractor reference call checklist

A useful reference should be a real recent customer with a completed project similar enough to test the contractor experience claimed for the proposed work.

Ask when and where the work occurred, what was built or repaired, approximate scope, whether the home was occupied, and how the reference knows the contractor. Cross-check public project photos, permits, reviews, or address information only where lawful and appropriate.

- Reference cannot describe the project

- Only very old or unrelated work is offered

- Same person appears under several different names

- Contractor insists on joining or controlling the call

The reference should be able to explain whether the original proposal was complete, how allowances and exclusions worked, what changed, and whether the final price was understandable and documented.

Ask what was omitted from the initial bid, whether substitutions or hidden conditions arose, how change orders were priced, and how the final invoice compared with the signed contract. Request examples rather than a simple satisfaction rating.

- Low bid followed by repeated add-ons

- Verbal changes appeared only on final invoice

- Allowances were unrealistic or unclear

- Owner cannot explain why final cost increased

The contractor should manage start dates, work sequencing, crew availability, access, protection, cleanup, and delays in a way consistent with the proposed project.

Ask when work actually started and finished, how often crews were present, who supervised, whether the project stopped unexpectedly, and how weather, permits, materials, or subcontractor delays were communicated.

- Deposit taken months before a reliable start

- Crew disappeared without explanation

- No consistent supervisor or point of contact

- Schedule promises were repeatedly reset verbally

Required permits, inspections, licensed trades, and subcontractors should be coordinated transparently, with the responsible contracting entity remaining accountable for the agreed work.

Ask who obtained permits, whether inspections passed the first time, whether unexpected correction notices occurred, which subcontractors were used, and whether the owner was asked to bypass permit or licensing requirements.

- Owner was pressured to pull a contractor permit

- Inspection corrections delayed closeout

- Unknown subcontractors arrived without notice

- Contractor disclaimed responsibility for subcontractor defects

The reference should describe observable workmanship, protection of existing property, correction of defects, and how acceptance issues were handled before final payment.

Ask what defects were found, how the punch list was recorded, whether corrections were completed promptly, whether damage occurred to occupied areas, and what the owner would inspect earlier if repeating the project.

- Defects were dismissed as normal without explanation

- Final payment was demanded before punch-list completion

- Existing finishes were damaged and not restored

- Reference would require independent inspection next time

A contractor relationship should be evaluated beyond the final invoice, including documentation, callbacks, warranty response, and whether the customer would hire the same contractor again for the same type of work.

Ask whether manuals, warranties, receipts, permits, and releases were delivered; whether any defect appeared later; how quickly calls were returned; and the exact reason the owner would or would not hire the contractor again.

- Communication stopped after final payment

- Warranty promise was verbal and later denied

- Closeout documents were never delivered

- Positive rating is vague but specific experience is negative
