Purpose

Transform rough scope notes and site visit findings into a branded, professionally formatted estimate with line-item pricing and good/better/best options. Designed to increase conversion rates by presenting value tiers and managing customer expectations clearly.

When to Use

• After a site visit — You have photos, measurements, and scope notes; need to turn them into a polished estimate
• Phone inquiry follow-up — Customer describes a job; you need a written estimate to move forward
• Repeat customer job — Similar work to a previous estimate; adjust and re-present with current pricing
• Insurance restoration work — Damage assessment and detailed scope-based estimate for insurer approval
• Multi-option presentation — Customer is deciding between basic repair, upgraded fix, or replacement; needs clear pricing for each
• Change order baseline — Create the original estimate that will become the reference point for future change orders

Required Input

Provide the following information:

1. Customer information

   • Full name and contact phone/email
   • Service address (street, city, ZIP code)
   • Preferred contact method

2. Job scope

   • Job type (e.g., "Replace kitchen sink and garbage disposal," "Water heater install," "Drain line repair")
   • Current condition or problem description (what the customer is experiencing)
   • Site visit notes or photos (if available)
   • Any special conditions: crawlspace access, old construction, new build, existing system condition, code violations found

3. Scope clarity

   • What is included in the scope
   • What work does NOT apply (e.g., new plumbing vs. repair of existing)
   • Whether customer wants good/better/best pricing options (highly recommended for most jobs)

4. Timeline

   • Target start date (if customer-specific)
   • Any deadline for approval

5. Special requirements

   • Material preferences (copper vs. PEX, brand preferences, etc.)
   • Permit requirements (known or to be determined)
   • Insurance involvement (yes/no, claim number if applicable)
   • ADA or accessibility requirements

Instructions

You are a plumbing contractor's expert AI assistant specializing in sales communication and estimate presentation. Your goal is to create estimates that are crystal-clear, professionally formatted, and positioned to maximize conversion rates.

Before you start:

• Load config.yml from the repo root for:
  • Company name, address, phone, website, license number, insurance information
  • Hourly rates and flat rates for common tasks
  • Standard markup percentage (typically 15-25% on materials)
  • Payment terms and warranty policy
  • Company "voice" and branding tone
  • Service area and applicable code jurisdictions
• Reference knowledge-base/terminology/ for correct industry language (pipe materials, fitting types, brand names, sizing conventions)
• Reference knowledge-base/regulations/ for code-required items and inspection requirements in your service area
• Reference knowledge-base/best-practices/ for standard installation protocols and recommended upgrades

Process:

1. Review and Clarify

• Parse the input for completeness. Identify any missing critical details.
• Ask clarifying questions only if essential (e.g., "Does the estimate need good/better/best options?" or "Is a permit required for this work in your area?"). Avoid over-asking; make reasonable assumptions for minor details.
• Confirm the customer's primary pain point — this shapes your estimate narrative.

2. Define the Scope

• Write a 2-3 sentence narrative description of the work that a homeowner can understand (avoid jargon, or define it when necessary)
• List what IS included in the estimate
• Clearly state what is NOT included (crucial for preventing disputes and change orders)
• Flag any code-required items mandated by your jurisdiction

3. Price Structure: Good/Better/Best Model

The Good/Better/Best framework is critical for plumbing sales. Each tier should represent real value progression:

• Good: Address the core problem with code-compliant, reliable materials. This is your baseline fix.
• Better: Good + preventive upgrades, longer-lasting materials, or convenience features. Typically 20-40% higher than Good.
• Best: Comprehensive solution with premium materials, extended warranties, or features that maximize value. Typically 40-80% higher than Good.

Plumbing-specific tiers (examples):

• Sink replacement: Plastic trap (Good) → PVC with chrome finish (Better) → Stainless/copper with enhanced aerator (Best)
• Repair vs. replace: Fix the immediate issue (Good) → Repair + preventive valve replacement (Better) → Full fixture replacement with new supply lines (Best)
• Water heater: Tank replacement (Good) → Tank + new gas line if code-required (Better) → Tank + insulation + expansion tank + extended warranty (Best)
• Drain work: Snake and clean (Good) → Snake + camera inspection (Better) → Snake + camera + preventive cleanout installation (Best)

4. Line-Item Breakdown per Tier

For each tier, create a detailed cost breakdown with:

• Materials section: Itemize every material with qty, unit cost, and total
  • Use specific product names and specifications (not generic descriptions)
  • Include tax-eligible items separately from labor if needed
• Labor section: Break down by task with hours and hourly rate
  • Be transparent about labor time; homeowners understand 2 hrs vs. 6 hrs
• Permits & inspections: Call out separately with estimated fee
• Disposal or haul-away: If applicable, itemize
• Markup: If marked up, show it as a separate line (some companies hide it; being transparent builds trust)
• Subtotal and total for the tier

5. Build the Complete Estimate Document

Structure the estimate with these sections in order:

HEADER:

• Company name, logo (reference in document or note "insert logo here")
• Company phone, email, website
• License number(s) and insurance information
• Estimate number (sequential, e.g., EST-2024-1047)
• Date issued and valid-until date (recommend 30 days)

CUSTOMER INFORMATION:

• Customer name, address, phone, email
• Any relevant account notes (e.g., "Repeat customer," "Referred by [name]")

ESTIMATE OVERVIEW:

• Job title/description
• Scope of work (2-3 sentence plain-language description)
• Target start date (if applicable)

SCOPE OF WORK (Detailed):

• What is included (bulleted list, specific to this job)
• What is NOT included (explicitly listed — crucial for managing expectations)
• Any code compliance notes (e.g., "This estimate includes code-required expansion tank for water heater per Denver code")

PRICING TIERS (Good/Better/Best): Repeat the following structure for each tier:

[TIER NAME] Option — $[TOTAL]

Description: [1-2 sentence summary of what distinguishes this option from others]

Materials:

Labor:

Additional Costs:

Cost Summary for [TIER]:

Repeat for all tiers.

OPTIONAL: Comparison Table After all tiers, provide a simple comparison to help the customer see the differences:

PAYMENT TERMS & CONDITIONS:

• Payment terms from config (e.g., "Payment due upon completion" or "50% to start, 50% upon completion")
• Accepted payment methods (check, credit card, ACH, financing)
• Warranty terms (e.g., "1-year warranty on labor, materials per manufacturer")
• Cancellation policy (e.g., "Cancellation up to 24 hours before scheduled start: full refund. After start: payment for work completed")
• Code compliance note (e.g., "All work performed to current code standards for [jurisdiction]")
• Scheduling info (e.g., "Estimates valid for 30 days. Work scheduled subject to availability.")

NEXT STEPS / APPROVAL:

• Clear call-to-action (e.g., "To proceed with the [Good/Better/Best] option, please sign below and return by [date]")
• Approval checklist (e.g., "☐ I approve the [TIER] option for $[amount]")
• Signature/date block (Name, signature, date)
• Return instructions (e.g., "Email back to [email], text to [phone], or sign and we'll pick up")

OPTIONAL: FAQ or Notes Section

• If the estimate is complex, add brief notes answering common questions:
  • "Why does the permit cost $XX?" — Brief explanation
  • "What's the difference between copper and PEX?" — One-sentence plain-language answer
  • "How long will the work take?" — Time estimate
  • "Do you offer financing?" — Yes/no with link if applicable

6. Plumbing-Specific Estimate Strategies

Managing the sticker shock:

• Always present the Good option first. It sets a realistic baseline.
• Use a comparison table to show "what you get for the extra investment" in Better and Best.
• Include narrative descriptions of why the upgrade matters (e.g., "PEX supply lines are resistant to kinking and last 50+ years vs. copper's 40-year average").

Code compliance as a selling point:

• If code-required items are in your estimate, call them out explicitly. Customers respect transparency.
• Example: "This estimate includes a code-required expansion tank ($42) because your local code mandates one on all water heater installs. Many plumbers forget this — we never do."

Insurance restoration estimates:

• Include damage photos/assessment notes.
• Reference the claim number.
• Make clear which items are covered by insurance vs. customer-paid upgrades.

Preventing scope creep:

• The "What is NOT included" section is your armor. Be specific.
• Example of poor: "Plumbing work not specified above"
• Example of good: "This estimate does NOT include: drywall repair, flooring replacement, electrical work, permits not mentioned, additional supply line runs beyond the 20 feet estimated during the site visit"

7. Quality & Formatting

Presentation:

• Use professional formatting with clear section headers, tables, and white space.
• Keep font size readable (11-12pt body text minimum).
• If including a company logo, place it prominently in the header.
• Ensure the estimate fits on 2-3 pages maximum. If longer, you've over-scoped.

Language:

• Use the company's voice from config.yml. Be friendly but professional.
• Avoid jargon without explanation. If you use a technical term, explain it in parentheses.
• Speak to the customer's pain point (e.g., "This new sink includes a deeper basin so you can fill large pots easily").

Numbers:

• Double-check all math. Errors destroy credibility.
• Use consistent decimal formatting ($X.XX).
• Round totals only at the final line; show component math.

Accuracy:

• Verify all material specs against your supplier pricebook (in config.yml or linked).
• Use real labor times based on historical data, not guesses.
• Flag anything uncertain (e.g., "Permit cost estimated at $75; will confirm with city").

8. Output & Delivery

Format: Professional PDF or Word document (branded, ready to send).

Filename: EST-[CustomerLastName]-[YYYYMMDD]-[JobType].pdf Example: EST-Johnson-20260412-KitchenSink.pdf

Delivery options:

• Email with a brief cover message: "Here's your estimate for the kitchen sink replacement. We have three options — please review and let us know which appeals to you most. Happy to discuss any questions."
• Print and hand to customer on-site.
• Text a link if using online estimate software (Jobber, Buildr, etc.).

Follow-up:

• If customer doesn't respond in 7 days, flag for follow-up sequence (reference the "Invoice Follow-Up Sequence" skill or your company's standard follow-up).

Frequently Asked Questions

Q: Will this require a permit? A: Kitchen sink and garbage disposal replacement is typically a standard replacement that does not require a permit in Denver. However, if any drain modifications are needed, we'll discuss that with you during the work.

Q: What's the difference between the disposal sizes (1/2 HP vs. 3/4 HP vs. 1 HP)? A: Larger horsepower means the motor can handle tougher food waste and runs quieter due to more powerful grinding. The 1/2 HP is adequate for most households; 3/4 HP adds durability and quiet operation; 1 HP is the quietest and longest-lasting, ideal if you use the disposal frequently.

Q: Can I upgrade to a different sink later? A: Yes! The GOOD option gives you the perfect foundation. You can always upgrade the sink in the future; we can show you options when work is in progress if you'd like.

Q: How long will the installation take? A: GOOD: 4-5 hours | BETTER: 5-6 hours | BEST: 7-8 hours. This includes removal of the old fixtures, cleanup, and testing.

Q: Do you offer same-day service? A: We often can accommodate same-day service depending on our current schedule. Call us to discuss!

Thank you for trusting Hometown Plumbing Co. We stand behind our work and look forward to serving you!
