- Dana’s $14,200 bathroom bid finished at $18,050, or $950 above the $17,100 bid she turned down. The gap was written into the cheaper quote before she signed.
- The Federal Trade Commission says a written estimate needs four things: a description of the work, the materials, a completion date, and the price.
- A change order counts only if it names the scope, the exact dollar amount added or subtracted, and the effect on the payment schedule, in writing, before work starts.
- Sign at your own kitchen table for $25 or more and federal law gives you until midnight of the third business day to cancel.

Dana in Peoria had two bids on the same hall bathroom: $14,200 and $17,100. She took the cheaper one. Four months later she had written checks totaling $18,050, which is $950 more than the bid she rejected. Nothing went wrong on the job. Her tile cost more than the allowance reserved for it, permits were not in the price, drywall repair was billed as extra, and a soft subfloor was excluded as structural work. All four were visible in the document she signed.
The four things every quote has to contain
Check first that each bid is actually a bid. The FTC’s guidance on how to avoid a home improvement scam sets a floor: a written estimate should include a description of the work to be done, the materials, a completion date, and the price. A one-page bid reading “master bath remodel, $14,200” is not a cheaper version of a six-page bid. It is unpriced.
The FTC also names a tactic that hides inside an otherwise normal-looking quote: a contractor who asks you to pull the required permits. Permits create an inspection record and put the licensed party on the hook for code compliance. Pushing them onto you moves that liability to the homeowner and often means the contractor cannot pull them. A line reading “permits by owner” is the first thing to ask about.
Get three estimates in this format, each carrying the license number and start and completion dates, and verify that license and a current certificate of insurance before you read any prices. That vetting sequence comes first.
Allowances turn a fixed price into a variable one
An allowance is a dollar amount the contractor sets aside for a material you have not chosen yet: tile, fixtures, hardware, countertops, lighting. They are legitimate, and they are also the most common reason a fixed-price bid does not stay fixed, because the contractor picks the number and you pick the product.
Dana’s cheaper quote reserved $4.50 per square foot for tile across 130 square feet of wall and floor, or $585. She chose a porcelain at $9.25. The arithmetic that hit her invoice:
– Material overage: $4.75 per square foot times 130 square feet equals $617.50. – Change-order markup at 15 percent: $92.63, for $710 added to a $585 line.
That is not a contractor behaving badly. It is a $585 line that was always going to cost $1,295 once a real product was chosen. Convert allowances into selections before you sign: walk the tile shop first, then have the contractor write that product into the quote by manufacturer and model. A bid naming actual products is the more honest number even when it prints higher.
| What the line says | What it can actually mean | What to get in writing instead |
|---|---|---|
| Tile allowance: $4.50/sq ft | You pay every dollar above $4.50, plus markup | The manufacturer, product name, and installed price for the tile you chose |
| Permits by owner | No inspection record, and possibly no license to pull them | Permits pulled and paid by the contractor, cost shown as its own line |
| Standard demo included | Removal only, with haul-away and dump fees billed later | Demolition, debris removal, and disposal fees, priced together |
| Subject to material price increases | Open-ended right to raise the price at any time | An escalation clause with a named trigger, a percentage cap, and an expiration date |
| Repairs to hidden damage billed as extra | The most likely surprise on the job is unpriced | A written unit rate for common repairs, such as per sheet of drywall or per square foot of subfloor |
| Balance due on completion | Completion is defined by the contractor | Final payment released after the final inspection passes and your punch list is closed |
The exclusions list is where the money hides
Every quote has an exclusions section, and most homeowners skip it because it reads like boilerplate. It is the most important page in the file.
Dana’s exclusions accounted for $3,140 of her $3,850 in overages: permits at $310, drywall repair at $840, subfloor replacement at $1,600, haul-away at $390. The bathroom remodeler whose $17,100 bid she rejected had priced three of those four into the base number. Not more expensive. More complete.
Read the list with one question: which of these is likely on my house? Hidden water damage behind a wet wall is likely, not exotic, and on a home built before 1978 lead-safe practices apply to anything that disturbs paint. If the quote excludes the most probable event, you have a starting bid rather than a price. Get a written unit rate on each excluded item, then align all three bids to a single scope before comparing. The lowest bid is the right choice less than half the time, and this is how you learn which half you are in.
Change orders, escalation clauses, and your cancellation window
Three clauses decide how much control you keep after signing.
The change-order clause. California’s statute is a useful benchmark anywhere, because it spells out what a change order has to do. Under Business and Professions Code section 7159, extra work becomes part of the contract only when written and signed by both parties before that work begins, and the order must describe the scope of the change, the cost added or subtracted, and the effect on the schedule of progress payments. Hold every change order to those three elements.
The escalation clause. A materials-escalation clause is not automatically predatory. Prices really are moving: the Bureau of Labor Statistics construction materials index (series WPUSI012011) stood at 369.3 in June 2026 against 338.7 in June 2025, about 9 percent in twelve months, so a contractor quoting a job that starts in ninety days carries real exposure. What makes the clause abusive is the absence of limits: insist on a named trigger such as a published index, a percentage cap, and an expiration date after which the price locks.
Your cancellation right. If you signed at your home rather than at the contractor’s place of business, the FTC’s Cooling-Off Rule applies to any sale of $25 or more. Under 16 CFR Part 429, you may cancel before midnight of the third business day after the transaction date, and the seller must hand you a completed cancellation notice in duplicate, in ten point boldface type. A kitchen-table signing with no cancellation form attached is a federal violation, and it tells you what the rest of the job will look like.

Frequently asked questions
Should a contractor quote be a fixed price or a range? Ask for a fixed price with allowances converted into named products and likely repairs priced as unit rates. A range is fine at the walkthrough stage, but the document you sign should carry one number plus a written method for changing it.
Can a contractor raise the price after I sign because material prices went up? Only if the contract lets them, and only within the limits the clause sets. Require a named trigger, a percentage cap, and an expiration date. Without those three, you have agreed to an open-ended price on a job you thought was fixed.
Do I really have three days to cancel a contract I signed at home? Yes, for sales of $25 or more made at your residence, under the FTC Cooling-Off Rule. The clock runs to midnight of the third business day, and the contractor must hand you a cancellation form in duplicate at signing. Cancel in writing and keep proof.
How do I compare three quotes that all describe different work? Normalize them before looking at price. List every line item appearing in any of the three bids, then fill in each contractor’s number, adding a market estimate where a bid is silent. Once all three cover the same scope, the outlier becomes obvious.
