How many quotes should I get?+
Three is the standard guidance for any job above a few hundred dollars. Fewer leaves you without a benchmark; more delays the work and rarely changes the answer.
Is a 50% deposit normal?+
For most residential service work, no. Ten to thirty percent is typical, and several states cap deposits. Large custom orders — cabinetry, windows, specialty equipment — are a legitimate exception.
How do I know if a contractor quote is too high?+
Get three quotes. If one is more than 30% above the others, ask what it includes that the others do not — premium materials, warranty, permit, or scope differences may explain it. If the high bidder cannot explain the gap, it is overpriced. The lowest bid is equally suspect if 30% below.
What should a roofing quote include?+
Scope: tear-off or overlay, shingle brand and warranty, underlayment type, flashing replacement, drip edge, ridge vent, and disposal. Price per square (100 sq ft), total squares, and timeline. A complete quote for a 2,000 sq ft roof: 20 to 25 squares at $400 to $600/square = $8,000 to $15,000.
What should an HVAC replacement quote include?+
Equipment brand, model, SEER/AFUE rating, tonnage, line set replacement, thermostat, permit, disposal of old unit, warranty (parts and labor), and start-up commissioning. A 3-ton SEER 16 replacement should quote $5,000 to $8,000 installed. Quotes under $4,000 likely exclude scope.
Should a quote include permit costs?+
Yes. A complete quote includes permit fees ($50 to $500), inspection scheduling, and any required engineering. A quote that says 'permit by owner' shifts $200 to $500 in cost and liability to you. The contractor should pull the permit in their name and license.
What is a reasonable contractor markup?+
Overhead and profit of 10 to 20% on top of direct cost is standard for residential work. On a $5,000 direct cost job, the contractor's price of $5,500 to $6,000 is reasonable. Markup above 30% on labor and materials combined is high unless the scope is complex or specialized.
How do I compare contractor bids?+
Line up scope side by side: same materials, same inclusions, same warranty. A $8,000 bid that includes tear-off, disposal, and a 10-year warranty is cheaper than a $6,500 bid that overlays existing shingles with no warranty. Normalize scope before comparing price.
What warranty should a contractor offer?+
Labor warranty of 1 to 2 years is standard for residential work. Manufacturer warranties on materials (roofing, HVAC equipment) are separate and typically 10 to 25 years. Get warranty terms in writing in the contract. A contractor who will not warranty their labor for at least one year is a risk.
Is a written estimate binding?+
An estimate is typically non-binding — it is an approximation. A quote or proposal with a signature line becomes a contract when signed. Verbal quotes are unenforceable. Always get a written quote with scope, price, timeline, and payment terms before work begins.
What questions should I ask a contractor before hiring?+
Ask: Are you licensed and insured? Will you pull the permit? What is included and excluded? What is the payment schedule? What warranty do you offer? Can I have three recent references? Who will be on site daily? A contractor who hesitates on any of these is a risk.
Does a high score mean the contractor is dishonest?+
No. It means the quote is incomplete or uses terms worth questioning. Many reputable shops write terse proposals; the score gives you a checklist, not a verdict.
Can I paste a photo of a quote?+
Type or paste text for accurate line weighting. If you only have a photo, transcribe totals and major lines — the tool cannot OCR images in the browser.
What deposit percentage is normal?+
Ten to thirty percent at signing for most residential jobs, with progress tied to milestones. Custom-order goods (windows, cabinets) may justify higher deposits tied to factory deposits.
Should every quote include permit fees?+
Yes for permitted work. A line item or explicit ‘permit included’ language should appear. ‘Owner to pull permit’ shifts cost and liability to you.
How do allowances work?+
Allowances should state the dollar cap and what happens if selections exceed it. Open-ended ‘tile allowance’ without quantity or price per square foot is a common dispute source.
Is one quote enough to analyze?+
You can analyze one, but three comparable scopes are the standard for price benchmarking. Use quote comparison when you have multiple bids.
What if all lines are one lump sum?+
The tool still checks total against benchmarks and terms. Ask the contractor to break out equipment, labor, permit, and disposal before signing.
Do commercial quotes use the same benchmarks?+
No. This tool targets residential service and remodeling. Commercial bids need different overhead and bonding assumptions.
How do change orders affect the analysis?+
Analyze the base contract first. Change orders should be written with scope, price, and schedule impact — the same completeness rules apply.
What warranty language should I expect?+
One to two years of labor on workmanship plus manufacturer material warranties stated by brand. ‘Warranty per manufacturer only’ with no labor coverage is a gap to question.
