Sometimes DIY inspection isn't enough. Professional siding inspection — for pre-purchase, pre-listing, problem-diagnosis, or insurance — has a place. Here's the cost framework.
Pre-purchase home siding inspection
When buying a home, siding inspection as part of due diligence. Typical scope: visual every elevation, moisture meter on suspect areas, photographic documentation, written report. Cost: $300-$800 standalone; sometimes bundled in general home inspection.
Pre-listing siding inspection
Before listing your home for sale, professional inspection identifies issues you'll need to address or disclose. Helps avoid surprise inspection findings during buyer due diligence. Cost: similar to pre-purchase, $300-$800.
Problem-diagnosis inspection
When specific issues appear (water staining, cupping, suspected substrate damage), inspection to scope the problem. May include partial opening of cladding for substrate visibility. Cost: $500-$1,500 depending on scope; sometimes credited against repair work if you proceed with the inspecting contractor.
Insurance-claim inspection
After damage events, inspection for insurance documentation. Sometimes the insurer's adjuster does this; sometimes you hire independent inspector. Cost: $400-$1,000 typically.
WUI hardening inspection
For Safer from Wildfires documentation, inspection confirming Chapter 7A assembly compliance. Useful for insurance retention conversations. Cost: $400-$1,200 typical.
What's included in professional inspection
Visual examination of every accessible elevation. Moisture meter readings on suspect areas. Sometimes thermal imaging (for hidden moisture). Photographic documentation. Written report with findings and recommendations. Some inspectors include limited intrusive examination (small opening of suspect area) for fee.
When DIY inspection is sufficient
Annual maintenance walkthroughs. Cosmetic issue identification. Decision-confirmation when you already know what you're looking at. Where DIY isn't sufficient: pre-purchase due diligence, pre-listing scope decisions, problem-diagnosis where the cause isn't clear, insurance documentation.
