Top Home Inspection Red Flags & Repair Costs
If your inspection report identifies any of the following critical defects, use the findings to request seller credits, require licensed contractor repairs prior to closing, or exercise your inspection contingency clause:
| Defect / Safety Issue | Potential Hazard | Average Repair / Replacement Cost |
|---|---|---|
| Failing or Aging Roof | Active interior water damage & mold | $8,000 “ $22,000 |
| Collapsed Sewer Line / Roots | Raw sewage backup into home | $4,500 “ $20,000 |

How to Choose a Qualified Home Inspector
- Verify Professional Certification Look for inspectors certified by either ASHI (American Society of Home Inspectors) or InterNACHI (International Association of Certified Home Inspectors). These organizations require strict continuing education and rigorous testing.
- Check Errors & Omissions (E&O) Insurance Ensure your inspector carries both General Liability and E&O insurance. This protects you in the rare event a major defect is overlooked.
- Ask for a Sample Report Modern inspectors provide digital PDF reports with clear high-resolution photos, infrared thermal imaging, and categorized repair priorities (Immediate Safety Hazard vs. Maintenance Item).
- Attend the Inspection in Person Always attend at least the final hour of the inspection walkthrough. A good inspector will walk you through the property, point out water shutoff valves, and explain routine maintenance requirements.
Frequently Asked Questions — Home Inspection Costs
How much does a standard home inspection cost in 2026?
A standard home inspection in 2026 costs between $300 and $550 for an average 1,500 to 2,500 square foot single-family home. Smaller condos cost $250–$350, while larger homes (over 3,500 sq ft) cost $600–$900+.
Who pays for the home inspection — buyer or seller?
The buyer almost always pays for the inspection. This ensures the inspector is working exclusively in the buyer's financial and safety interests.
Is a sewer scope inspection worth the money?
Yes. A $175–$250 sewer scope can uncover collapsed clay pipes, tree root intrusion, or belly dips that cost $4,000–$25,000 to dig up and replace. Standard homeowners insurance policies do NOT cover exterior sewer line replacements.
How much does radon testing cost?
Radon testing typically adds $125 to $175 when bundled with your home inspection ($200–$325 if ordered separately). An electronic continuous monitor tests indoor air levels over a 48-hour period.
What is included in a standard home inspection?
A certified inspection covers the roof, attic insulation, exterior drainage, foundation, electrical panels, plumbing fixtures, water heater, HVAC systems, windows, doors, and major appliances.
What is NOT covered in a home inspection?
Standard inspections exclude inside finished walls, underground sewer lines, swimming pools, septic tanks, wells, asbestos, radon, lead paint, and mold unless ordered as specific specialty add-ons.
How long does a home inspection take?
An average home inspection takes 2.5 to 3.5 hours on-site. Large or historic properties can take 4 to 6 hours. Reports are usually delivered within 24 hours.
Can a home fail a home inspection?
No. Inspections are not pass/fail. The report provides an objective assessment that buyers use to negotiate seller repairs, price credits, or cancel the contract under the inspection contingency.
Are home inspection fees tax deductible?
For primary residences, inspection fees are added to your cost basis (lowering future capital gains tax when selling). For rental investment properties, they are deductible as an ordinary business expense.
