The most successful home inspection businesses don't just sell a standard home inspection; they sell peace of mind across the entire property. Ancillary services—often called "add-ons"—are the fastest way to increase your revenue without adding significantly more time to your day.

**1\. Sewer Scopes:** A sewer scope is one of the highest-margin services you can offer. With the right equipment, it adds 20 minutes to your on-site time but can add $150–$300 to your invoice.

**2\. Radon Testing:** Radon is a silent concern for many homebuyers. Offering 48-hour continuous monitoring provides a vital safety service and recurring revenue.

**3\. Mold and Air Quality Testing:** Water intrusion is a common defect. Being able to offer lab-certified mold samples on the spot turns a "visual observation" into a "documented fact," protecting the buyer and increasing your value.

**4\. Thermal Imaging (Infrared):** Using a FLIR camera to detect hidden moisture or electrical hotspots is a "premium" service that justifies a higher base fee.

**How do home inspectors increase their average invoice?** Inspectors increase their invoices by bundling ancillary services like sewer scopes, radon testing, and thermal imaging into "Premium Inspection Packages."

**What are the most profitable add-on services for inspectors?** Sewer scopes and radon testing are generally considered the most profitable due to high demand and relatively low ongoing material costs.
