Compare written estimates without losing track of fees
The smaller number is not necessarily the cheaper offer. One estimate may cover the diagnosis and repair; another may cover only the first visit. Before choosing, put each quote against the same job description and mark anything you cannot yet compare.
First, find out what the visit costs
Ask these questions before booking, and save the answers in writing:
- Is there a call-out, travel, inspection, or diagnostic fee?
- Is that fee payable if I decline the repair or the problem cannot be diagnosed?
- Is any diagnostic charge credited toward approved work? What conditions apply?
- Are evening, weekend, parking, mileage, or access charges additional?
- What is the cancellation policy, and when would a cancellation charge apply?
“Free estimate” needs a definition. It might mean a phone discussion rather than a diagnostic visit. Ask what the person will inspect or measure and what information you will receive afterward. Do not infer that a repair is included because someone is coming to inspect.
Put the same work on both sides of the comparison
The FTC recommends multiple written estimates describing the work, materials, completion date, and price. It advises against automatically choosing the lowest bidder and recommends asking about large differences.
For each estimate, identify the repair or replacement proposed, the equipment or material specification where relevant, and what remains excluded. Separate an identified repair from an allowance for work whose extent is unknown. Ask who pays for opening and restoring access, removing old materials, permits, and cleanup.
Mark an unanswered charge as unknown, not zero. Record whether tax is included, separately calculated, or not yet stated. A total cannot resolve a scope difference: patching a small area and replacing a larger assembly are different offers even when both are described as “fix the leak.”
An example of why the headline price can mislead
These numbers are invented to illustrate the arithmetic, not local market prices or a suggested budget. Both fictional offers cover the same repair, and all listed diagnostic charges are non-creditable.
| Charge | Offer A | Offer B |
|---|---|---|
| Diagnostic visit | $95 | $90 |
| Repair labor | $240 | Included in package |
| Parts | $110 | Included in package |
| Disposal | $25 | Included in package |
| Repair package | Itemized above | $430 |
| Total of listed charges | $470 | $520 |
The $430 repair package is not the complete $520 commitment. Conversely, do not add a fee twice when it is explicitly included or credited. Use the estimate comparison worksheet to organize actual quotes, then ask the provider to confirm the resulting total and any unresolved exclusions.
Agree on a change process before work begins
An inspection may uncover a different problem. Decide in advance who can approve extra work and how that approval will be recorded. A useful change record identifies the discovery, the proposed additional work, its price or pricing method, and any effect on completion. Keep it with the original agreement.
For time-and-materials work, ask about the labor rate, billing increments, material charges, and an approval point before the bill exceeds an agreed amount. If a price is only an estimate, ask what can change and when you will be told. Do not assume a verbal “probably” establishes a fixed price or that this worksheet changes your contract.
Tie payment to clear written terms
Clarify the deposit, payment milestones, accepted methods, and what counts as completion. The FTC advises against paying the full project amount upfront and says some states limit down payments. Applicable rules vary; verify local requirements for your particular project.
Ask who provides a warranty, what it covers, how long it lasts, and how to request follow-up. Retain the invoice and receipts, along with the final agreed scope. This guide helps you organize a decision; it is not a price quotation, legal review, guarantee of value, or assurance that a provider will respond.
