Intro

Home inspection work can open doors to steady jobs. You spot issues, explain risk, and propose fixes. Do it well, and clients trust you. This guide shows how a home inspection works from a contractor view. You'll get a step-by-step process, a simple checklist, and clear reporting tips. You'll also learn how to turn inspection notes into approved work without pushy sales. Use this as your field playbook. Keep it simple. Keep it honest. And win the work you deserve.

Quick Answer

A home inspection is a visual check of a home’s major systems to find safety risks, damage, and maintenance issues. For contractors, the goal is to document facts, explain impact, and present repair options. Plan 90–150 minutes on site, deliver a clear report within 24–48 hours, and include a clean proposal.

Key Takeaways

• Plan 90–150 minutes per home inspection, plus 60–90 minutes for reporting.
• Cover at least 10 major systems: roof to foundation to HVAC and electrical.
• Deliver reports within 24–48 hours with 3–5 photos per key issue.
• Note simple measurements: 1/8 inch cracks, 40–80 psi water pressure, 120°F water temp.
• Offer Good/Better/Best repair options to boost approval rates.

Home Inspection Basics for Contractors

A home inspection is a visual, non-invasive check. You aren’t tearing walls open. You’re looking for defects, safety hazards, and signs of failure. Think “what’s wrong, why it matters, and what to do.”

• What a home inspection covers: structure, exterior, roof, plumbing, electrical, HVAC, insulation/ventilation, interior, doors/windows, and site drainage.
• What it doesn’t: full code compliance, engineering analysis, or hidden conditions you can’t access.
• Where contractors fit: you already know how systems fail. Use that skill. Explain the cause, not just the symptom. Keep language simple.

If you’re also improving how you write professional proposals, see our guide on professional proposals. It pairs well with this process.

Step-By-Step Home Inspection Process

Follow these steps on every job. Consistency builds trust.

1. Confirm Scope And Access

   • Clarify which areas you’ll inspect. Note any locked spaces.
   • Explain limits: no destructive testing. Visual first.

2. Safety First Walkthrough

   • Smell gas? See live wires? Shut it down and alert the owner.
   • Document life-safety first. Plan fixes fast.

3. Exterior And Site

   • Start outside. Drainage and roof send clues inside.

4. Interior Pass

   • Go room by room. Doors, windows, floors, walls, ceilings.

5. Mechanical Systems

   • Electrical, plumbing, HVAC, water heater, appliances (as agreed).

6. Attic And Crawlspace

   • Look for moisture, ventilation, insulation, pests, structure.

7. Measure And Test

   • Water pressure (target 40–80 psi). Water temp (aim about 120°F).
   • GFCI/AFCI test where present. Operate basic functions.

8. Photograph And Label

   • Take 3–5 photos per major issue. Include wide, close-up, and label.

9. Prioritize Findings

   • Safety, active leaks, structural movement, then maintenance.

• Send within 24–48 hours. Keep it clear. Add repair options.

Home Inspection Checklist: Exterior To Interior

Use this quick list. Adjust to local needs and building age.

• Site And Drainage

  • Grade slopes away from home. Look for pooling after rain.
  • Downspouts extend 4–6 feet from foundation (commonly recommended).

• Roof And Gutters

  • Missing, curled, or cracked shingles. Soft decking spots.
  • Gutters clean and tight. No gaps at fascia.

• Exterior Walls And Openings

  • Siding damage, gaps, rot, missing caulk at penetrations.
  • Doors/windows open smoothly. Weatherstripping intact.

• Foundation And Structure

  • Horizontal cracks or step cracking. Note width. Hairline under 1/8 inch is often minor; monitor larger or expanding cracks.
  • Doors out of square or floors sloping indicate movement.

• Interior Rooms

  • Stains on ceilings/walls suggest leaks. Use moisture meter if available.
  • Handrails tight. Smoke/CO alarms present and working.

• Electrical

  • GFCIs near sinks, garages, exteriors, and baths (commonly within 6 feet of water). Test them.
  • Open junction boxes, double-taps, damaged cords—note and label.

• Plumbing

  • Water pressure 40–80 psi is typical. Look for hammer, slow drains.
  • Water heater set near 120°F. Signs of rust, leaks, or backdrafting.

This pairs well with understanding pricing strategies. If you struggle to price hidden-condition risk, see our guide on pricing strategies for clear markups and contingencies.

Documenting And Reporting Findings

Your report sells your skill. Keep it clean and decisive.

• Use Plain Language

  • Problem: “Active leak at hall bath trap.”
  • Impact: “Leak can damage subfloor in weeks.”
  • Fix: “Replace trap and seal connection.”

• Add Photos And Labels

  • 3–5 photos per issue: context, close-up, and after-fix (if done).

• Prioritize Clearly

  • Category 1: Safety/urgent (gas leaks, live wires, active leaks).
  • Category 2: Structural/moisture risks.
  • Category 3: Maintenance/efficiency.

• Give Options With Ranges

  • Good: stop leak, basic patch.
  • Better: partial replace, upgrade parts.
  • Best: full replace with warranty.

• Turn Notes Into Proposals Fast

  • Record voice notes on site and convert to a branded proposal using tools like Donizo. Send for e-sign within the same day to cut delays.

Turning A Home Inspection Into Work You Can Win

You’re not pushing. You’re guiding.

• Lead With Safety

  • Offer a 24-hour action plan for urgent hazards. Clients appreciate speed.

• Offer Good/Better/Best

  • Three clear levels close more deals than one fixed choice.

• Be Specific With Timeframes

  • “We can start in 3–5 business days. Work takes 1–2 days.”

• Set Assumptions

  • “Price based on visible conditions. Hidden damage may require a change order.”

• Make Approval Easy

  • Send a branded PDF with e-sign. After acceptance, convert to invoice in one click on platforms such as Donizo.

• Follow Up Once

  • A single, polite follow-up in 48–72 hours. No pressure. Just help.

This approach also helps with managing project timelines. If you need a system, see our guide on project timelines to avoid bottlenecks and idle crews.

Common Mistakes To Avoid

• Skipping The Attic Or Crawlspace

  • Many issues hide there: leaks, pests, poor insulation.

• No Measurements

  • Don’t just say “low pressure.” Log 40–80 psi readings. Note crack widths.

• Vague Photos

  • Use one wide and one close-up. Add arrows or labels.

• Overpromising

  • Be clear about visible-only scope. Use change orders for surprises.

• Delayed Reports

  • Past 48 hours, deal energy drops. Speed matters.

• Tech Jargon

  • Keep it simple. Explain cause, risk, and fix in plain words.

FAQ

What is included in a home inspection?

A home inspection covers major systems: roof, exterior, structure, plumbing, electrical, HVAC, insulation/ventilation, interior, doors/windows, and drainage. It’s visual and non-invasive. You identify defects, safety issues, and maintenance needs. You don’t open walls or guarantee code compliance unless contracted to do so.

How long does a home inspection take?

Plan 90–150 minutes on site for an average single-family home. Add 60–90 minutes for photos, notes, and report writing. Larger homes, older homes, or limited access can add time. Tell the client your expected timeline up front.

What tools should a contractor bring?

Bring a flashlight, ladder, outlet/GFCI tester, moisture meter, infrared thermometer, basic hand tools, camera or phone, PPE, and a water pressure gauge. These help you confirm issues and document them clearly without invasive testing.

Should I give a quote on site?

You can share ballparks for simple fixes, but avoid final prices until you finish photos and notes. It’s safer to send a written proposal within 24–48 hours with Good/Better/Best options. That reduces mistakes and change orders.

Can I do the repairs after the inspection?

Yes, if allowed by local rules and your agreement with the client. Keep roles clear: first, objective findings; second, repair options. Always disclose limits, and use a signed proposal before work begins.

Conclusion

A tight home inspection process builds trust and steady work. Keep it visual, measured, and clear. Document issues, explain impact, and offer simple repair options with fast turnaround. Next steps:

1. Use the checklist on your next job and time each step.
2. Take 3–5 labeled photos per major issue and log key measurements.
3. Send a clear proposal within 24–48 hours. Tools like Donizo help convert voice notes to branded proposals with e-sign and quick invoicing.

By following this playbook, you’ll reduce callbacks, close faster, and protect your margin.

HVAC

• System runs, filter clean, vents clear. Listen for abnormal noise.
• In general, a 16–22°F supply/return temperature difference suggests decent cooling. Note if far outside that range.
