Quote red flags: what actually inflates a price
Very few quotes are dishonest. Plenty are structured so you can't check them — one lump sum, a percentage fee with no basis, a discount that expires tonight. Here is the index of those patterns, by trade, with what each one hides and what to ask instead.
66 patterns
Plumbing quotes
One lump sum for everything
A single 'repair leak' line with no breakdown makes it impossible to tell whether you're paying for one hour or a full day.
Full guide for this tradePlumbing quotes
Repair quietly upgraded to replacement
Sometimes replacement really is the right call. But if you asked about a repair and got a replacement quote, ask directly what the repair would cost and why it was ruled out.

Emergency pricing on a non-emergency
After-hours and emergency rates are legitimate. They should not be applied to work scheduled for next Tuesday.

Bundled 'while we're here' items
Sometimes a genuine efficiency, sometimes padding. Ask which items are required now and which are recommended for later.
Full guide for this tradePlumbing quotes
Percentage-based miscellaneous fees
A percentage 'materials and supplies' or 'shop' fee applied on top of an already marked-up total compounds quickly.
Full guide for this tradeBrake quotes
Rotors replaced by default
Some rotors must be replaced, and many shops replace as standard policy. Either way, ask whether yours are below minimum thickness — that's the measurable answer.
Full guide for this tradeBrake quotes
All four corners when one axle was the complaint
Front and rear brakes wear at different rates. If the inspection only found wear on one axle, the estimate should reflect that.
Full guide for this tradeBrake quotes
Labour hours above book time
Extra time can be legitimate on a seized or rusted assembly, but it should be named as such rather than silently billed.
Full guide for this tradeBrake quotes
Calipers added without a symptom
Calipers are a large cost. Replacement should follow a specific finding — sticking, leaking, uneven wear — not appear as routine.
Full guide for this tradeBrake quotes
Bundled fluids and inspections
Flushes and multi-point inspections are cheap individually and add up when several appear on one estimate.
Full guide for this tradeRoof replacement quotes
No square count
Without a stated measurement, you cannot compare bids or check the material quantities against the price.
Full guide for this tradeRoof replacement quotes
Open-ended decking replacement
'Bad wood replaced at additional cost' with no per-sheet rate is the most common way a roof price grows after work starts.
Full guide for this tradeRoof replacement quotes
Storm-chasing urgency
Pressure to sign today, an insurance claim promised as a certainty, or a deposit demanded before any paperwork are all reasons to slow down.
Full guide for this tradeRoof replacement quotes
Full replacement for localised damage
Sometimes correct, sometimes not. Ask specifically whether a repair or partial replacement was considered, and why it was ruled out.
Full guide for this tradeRoof replacement quotes
Upgrades presented as requirements
Premium shingle lines and extended warranties are legitimate products. They should be a choice you made, not an assumption inside the number.
Full guide for this tradeRoof replacement quotes
A large deposit
Some deposit is normal for material ordering. A large share of the total before any work begins is worth questioning, and in some places it's regulated.
Full guide for this tradeDental cleaning prices
A deeper procedure billed as a cleaning
If scaling and root planing was performed, ask what the periodontal findings — pocket depths — were that justified it, and whether a routine cleaning was an option.
Full guide for this tradeDental cleaning prices
No codes on the statement
A statement showing only a total and 'dental services' prevents you from checking anything against your plan.
Full guide for this tradeDental cleaning prices
X-rays at every visit
Sometimes clinically indicated, sometimes routine policy. Ask what interval is recommended for you specifically.
Full guide for this tradeDental cleaning prices
Add-ons you weren't asked about
Fluoride and screenings applied without a conversation, especially when your plan doesn't cover them at your age.
Full guide for this tradeDental cleaning prices
A cleaning that exceeded your plan's frequency limit
The clinic may not have checked. This turns a routine covered visit into a full out-of-pocket one.
Full guide for this tradeDental cleaning prices
Out-of-network billing
Out-of-network clinics bill their full fee rather than a negotiated rate, so the same codes cost you more.
Full guide for this tradeWater heater quotes
One number, no equipment/labour split
Without the split you can't tell whether you're paying for a premium unit or premium labour.
Full guide for this tradeWater heater quotes
No model number
The unit is the one component with a verifiable market price. A quote that won't name it removes your only hard reference point.
Full guide for this tradeWater heater quotes
Urgency pricing on a working heater
A failed heater with active leaking is an emergency. A heater that's simply old is not, and you have time to get a second quote.
Full guide for this tradeWater heater quotes
Code upgrades not identified as such
Legitimate items, but you're entitled to know which are legally required and which are the installer's preference.
Full guide for this tradeWater heater quotes
Tankless quoted without the conversion costs explained
If the gas line, venting or electrical work is what makes tankless expensive, that should be visible so you can judge the upgrade on its merits.
Full guide for this tradeWater heater quotes
Extended warranties folded into the total
Sometimes worthwhile, but it should be a line you can decline.
Full guide for this tradeWindow replacement quotes
One project total with no per-window pricing
This is the single biggest obstacle to comparing window quotes, and the easiest thing to ask for.
Full guide for this tradeWindow replacement quotes
Same-day discount pressure
A price that's only available if you sign tonight is a sales tactic, not a market price. Any legitimate quote will still be honoured next week.
Full guide for this tradeWindow replacement quotes
Full-frame quoted where insert would do
Full-frame is sometimes essential. If your frames are sound, ask what insert replacement would cost instead.
Full guide for this tradeWindow replacement quotes
Glass package upgraded silently
Triple glazing or premium coatings may be the right choice, but you should be able to see the price difference and decline.
Full guide for this tradeWindow replacement quotes
Trim and capping excluded but not mentioned
Discovered after installation, this becomes an unavoidable extra at the contractor's price.
Full guide for this tradeWindow replacement quotes
A 'lifetime' warranty with no written terms
Ask what's covered, for how long, whether labour is included, and whether it transfers.
Full guide for this tradeElectrical quotes
'Electrical work' as a single line
No labour basis, no device list, no run description — nothing to evaluate.
Full guide for this tradeElectrical quotes
A panel upgrade appearing without justification
Sometimes genuinely required by capacity or an unsafe panel type. It should be explained in terms of your specific panel, not offered as routine.
Full guide for this tradeElectrical quotes
Safety-framed urgency
Real hazards exist and should be fixed. But 'this could burn your house down' with no specific finding written down is a pressure tactic.
Full guide for this tradeElectrical quotes
Percentage materials or shop fees
A percentage added to an already marked-up total on a labour-dominated job adds up quickly.
Full guide for this tradeElectrical quotes
Patching excluded silently
If drywall repair isn't included, you'll be hiring that separately — better to know before you approve.
Full guide for this tradeElectrical quotes
Permit fee marked up without saying so
Filing a permit takes time and can fairly be charged for. It should just be visible as such.
Full guide for this tradeInternet bill increases
An expired promotional rate
By far the most common cause. The bill didn't change unfairly — the discount simply ended on schedule.
Full guide for this tradeInternet bill increases
Long-running equipment rental
Charged every month for years on hardware that often costs less to buy outright.
Full guide for this tradeInternet bill increases
Add-ons nobody uses
Phone lines, TV tiers and receivers that were bundled at signup and never cancelled.
Full guide for this tradeInternet bill increases
Fees that sound governmental
Names resembling regulatory charges, listed alongside real taxes, but set by the provider.
Full guide for this tradeInternet bill increases
Automatic annual increases
Some contracts allow a yearly rise. Legal, and worth knowing about before you renew.
Full guide for this tradeInternet bill increases
A speed tier beyond your needs
Upgrades sold on peace of mind rather than usage. Most households need far less than the top tiers.
Full guide for this tradeHVAC and AC quotes
Good/better/best sheets with no model numbers
Three tiers on one page with round numbers and no model numbers means you cannot price-check any of them, which is usually the point.
Full guide for this tradeHVAC and AC quotes
Same-day discount that expires tonight
Legitimate seasonal promotions exist and last weeks. A discount that dies when the salesperson leaves your kitchen is a pressure tactic, not a price.
Full guide for this tradeHVAC and AC quotes
Full system sold on a failed part
A dead capacitor or contactor is a cheap fix. If a repair visit turns into a replacement quote, ask what the repair costs and how long the existing system is expected to last with it.
Full guide for this tradeHVAC and AC quotes
Efficiency upsell without a payback number
Ask what the annual saving is expected to be and how many years to pay back the difference. If nobody can tell you, the upgrade is being sold on feeling.
Full guide for this tradeHVAC and AC quotes
Financing quoted instead of price
A monthly payment is not a price. Get the cash total, then decide about financing separately.
Full guide for this tradeMechanic estimates
Bundled maintenance presented as the repair
Fluid flushes, filters and 'recommended services' attached to a repair estimate are separate decisions. Ask for them as a separate line so you can decline without changing the repair.
Full guide for this tradeMechanic estimates
Full book time on overlapping jobs
If two of the quoted operations require the same parts removed, ask whether the labour overlap has been credited.
Full guide for this tradeMechanic estimates
Parts swapped on suspicion
Replacing a sequence of parts to chase a fault charges you for the diagnosis. Ask what test confirmed the failed component.
Full guide for this tradeMechanic estimates
Safety framing on a maintenance item
Some items genuinely are urgent. Ask what happens if you wait a month, and whether the answer is 'it fails' or 'it gets worse slowly'.
Full guide for this tradeMechanic estimates
Estimate given verbally only
A number said out loud can drift by the time the invoice prints. Ask for the estimate in writing before work begins.
Full guide for this tradeMedical bills
A summary bill instead of an itemised one
'Hospital services — one line' cannot be checked by anyone. An itemised bill with codes is something you're generally entitled to ask for.
Full guide for this tradeMedical bills
Duplicate charges
The same code appearing twice for one service, or a supply billed both individually and as part of a bundle.
Full guide for this tradeMedical bills
Unbundling
Services that should be billed together as one code, split into several charged separately.
Full guide for this tradeMedical bills
A bill that arrives before the insurer has processed
Paying a first bill that hasn't been through insurance can mean paying list price. Match every bill against an explanation of benefits first.
Full guide for this tradeMedical bills
Quantity errors
A decimal or unit error — 10 units of a medication instead of one — is mundane, common, and expensive.
Full guide for this tradeMoving quotes
A quote given over the phone with no survey
A number produced without seeing or listing your belongings is a guess, and guesses adjust upward on moving day.
Full guide for this tradeMoving quotes
Deposit demands out of proportion
A modest deposit is normal. A large cash deposit before any inventory or paperwork is a warning sign.
Full guide for this tradeMoving quotes
Surcharges appearing at the truck
Long carry, stairs and shuttle fees charged on the day, when they were visible at the address all along.
Full guide for this tradeMoving quotes
Coverage sold as insurance
If cover is presented as though your belongings are fully protected, ask for the per-pound figure and the deductible in writing.
Full guide for this tradeMoving quotes
Broker in the middle
Some 'movers' sell your job on to a carrier you've never spoken to. Ask directly whether they are the carrier performing the move.
