Workflow
Use AI to review a contractor estimate before you sign.
Paste any contractor quote into H0U53 and get a checklist of what is clear, vague, missing, or a red flag — plus the specific questions you should ask before you approve the work.
Why estimate review matters
A contractor estimate is the only document standing between you and a much larger problem later: scope creep, surprise charges, missing permits, failed inspections, voided warranties, or a lien on your house. Most estimates are written quickly by people who do this work every day — for people who don’t. The gaps are usually unintentional. But they cost money.
H0U53’s Estimate Review workflow checks the quote against a sixteen-point list, surfaces every vague or missing item, and builds a numbered list of questions you can ask before you sign.
What H0U53 checks
- 1
Scope of work
Is every task explicitly described?
- 2
Materials
Specified by brand, model, and spec — or vague?
- 3
Labor
Included? Hourly or fixed?
- 4
Exclusions
What is NOT covered? Look for this section.
- 5
Permit responsibility
Who pulls the permit? Who pays?
- 6
Inspection responsibility
Who schedules and meets the inspector?
- 7
Demo + disposal
Tear-out and haul-away included?
- 8
Access assumptions
Wall openings, ceiling cuts, surface protection?
- 9
Patch / paint / finish
Restoration of disturbed surfaces included?
- 10
Warranty
Materials and labor — and for how long?
- 11
Timeline
Start date, duration, and milestone commitments.
- 12
Payment schedule
Deposit, progress, completion. Avoid large up-front deposits.
- 13
Change-order process
How are mid-project additions priced and approved?
- 14
License + insurance
License number, GL insurance, workers' comp.
- 15
Lien waiver
Will you get one upon final payment?
- 16
Red flags
Cash-only, no contract, pressure to start today.
Vague estimate vs. better estimate
Two real-style line items for the same job. Notice the difference.
“Replace water heater. Includes labor and materials. Permit not required.”
- No fuel type, capacity, brand, or model.
- No mention of T&P valve, pan, drain, expansion tank.
- No earthquake straps (if required in seismic zone).
- No sediment trap on the gas line.
- “Permit not required” — verify with your local building department before relying on this.
“Replace existing 50-gal gas water heater with Bradford White RG250T6N (50 gal, 0.62 UEF, atmospheric vent). Includes new T&P valve, pan + 3/4″ PVC drain to approved location, expansion tank, earthquake straps, and sediment trap on gas line. Permit pulled by contractor; inspection scheduled within 7 days of install. 1-year labor warranty in addition to manufacturer 6-year tank warranty.”
Common red flags
- Cash-only payment with no written contract.
- Deposit larger than 25% before any work begins.
- Pressure to sign or start today.
- License number missing, expired, or refused on request.
- "Permit not needed" for plumbing, electrical, gas, or structural work.
- "Warranty: as per manufacturer" — no labor warranty from the contractor.
- Vague material specifications ("as needed," "contractor's choice").
- Scope written as "miscellaneous" or "as required" without itemization.
- No exclusions section — everything is implied to be included until it isn't.
- Refusal to provide proof of GL insurance or workers' comp.
What H0U53 produces
- Per-category labels: clear / vague / missing / red flag.
- A list of vague language you can ask the contractor to tighten.
- Missing categories the contract should address — permit, lien waiver, change-order process, warranty terms.
- Numbered questions to ask the contractor before signing.
- Questions to verify with your local building department.
Do not sign a vague estimate.
Paste the quote into H0U53 first. You will get a checklist of what is clear, vague, missing, or a red flag — plus the questions to ask before you approve the work.
