Frequently Asked Questions

Expert answers to common inspection questions

Is a foundation inspection separate from a home inspection?
Yes, they’re different. General home inspectors check foundations briefly but aren’t specialists. Foundation inspections provide detailed structural analysis, precise measurements, and engineering assessments. For homes with visible issues or those over 20 years old, a separate foundation inspection is recommended. Cost adds $300-500 but can save tens of thousands by identifying issues home inspectors miss.
How long does a foundation inspection take?
Basic visual inspections take 1-2 hours. Comprehensive engineering inspections require 2-4 hours on-site, plus 2-3 days for report preparation. Factors affecting time: property size, crawl space access, number of issues found, and testing required. Larger homes or those with basements take longer. Emergency inspections can provide preliminary findings same day with full reports following.
Should I get an inspection if I don’t see problems?
Yes, especially for homes over 10 years old. 70% of foundation issues develop slowly without visible signs initially. Annual or bi-annual inspections catch problems when repairs cost $500-2,000 instead of $10,000-30,000. Think of it like dental checkups – prevention is far cheaper than major repairs. Cost of inspection is typically less than 1% of potential repair costs.
What’s the difference between an engineer and regular inspector?
Structural engineers have advanced degrees and PE licenses, can perform calculations, design repairs, and provide stamped reports accepted by courts and permitting offices. Regular inspectors identify problems but can’t design solutions. Engineers cost more ($500-800 vs $300-500) but are essential for major issues, insurance claims, or legal matters. Both serve important roles depending on your needs.
Can sellers refuse foundation inspection?
Sellers can refuse, but it’s a major red flag. Most purchase contracts include inspection contingencies. Refusing suggests known problems. In this case: include inspection contingency in offer, consider walking away, or significantly reduce offer price to account for unknown risks. If purchasing anyway, budget 10-20% of home price for potential repairs.
How accurate are free inspections from repair companies?
Free inspections can identify real problems but come with inherent bias – companies profit from finding issues. Use them for second opinions or repair quotes, not primary diagnosis. Best practice: get independent inspection first ($300-500), then free quotes from 3-4 repair companies. This approach provides unbiased assessment plus competitive pricing.
What if inspection finds major problems?
Don’t panic. Get repair estimates from 3-4 contractors. For buyers: negotiate price reduction, request repairs, or walk away if too severe. For owners: prioritize safety issues, get multiple opinions, check insurance coverage, consider financing options. Remember: most issues are repairable, and early detection saves money. Engineer reports help determine if problems are stabilized or actively worsening.
