Why Add On?

What I’ve learned from offering ancillary services

by Henry Sander June 18, 2025

Offering ancillary services has been an invaluable learning experience—professionally and operationally. Here is some of what I’ve learned: 

Client Education is Key. Many clients are unfamiliar with the benefits of ancillary services or don’t realize how these inspections can save them time, money, and stress in the long run. We’ve learned the importance of clearly explaining the value of services like radon testing, sewer scope inspections, and chimney evaluations during initial consultations. Educated clients are more likely to opt for these services when they understand how they address potential risks or add insight into their property.

Inspector Training and Certification Matter.
Expanding into ancillary services required us to invest in specialized training, certifications, and equipment. This not only ensures that we provide accurate, reliable results but also builds trust with clients and sets us apart from competitors. 

Bundling Services Increases Revenue and
Convenience.
Offering bundled packages that combine standard inspections with ancillary services has been a game-changer. Clients appreciate the convenience of one-stop shopping, and it has increased our average revenue per inspection. Bundling also helps us streamline scheduling and reduce operational complexity.

Ancillary Services Build Client Trust. By providing add-on services, we position ourselves as a comprehensive resource for homebuyers. This not only adds value to the transaction but also fosters long-term trust. Clients see us as experts who are committed to their safety and investment, which leads to more referrals and repeat business.

Preparation Minimizes Liability. Offering ancillary services means venturing into areas with additional technical and legal considerations. We’ve learned to protect ourselves by being thorough, documenting findings clearly, and maintaining proper liability coverage for specialized services. This preparation reduces risk and ensures client confidence in our work.

Value-Added Services Strengthen
Relationships.
Real estate agents and repeat clients have become some of our biggest advocates for ancillary services. These offerings show that we go above and beyond basic inspections, which helps solidify relationships and encourages ongoing referrals.

Adding ancillary services has taught us that the key to success lies in preparation, education, and responsiveness to client needs. It’s not just about increasing revenue—it’s about delivering a more thorough, valuable experience for our clients while growing as professionals in the industry.


A Closer Look at 6 Ancillary Services


Each of these services complements our standard inspections, provides a more comprehensive evaluation, and ensures our clients feel confident about their investment. Additionally, the convenience of bundling these services has strengthened client satisfaction and loyalty, which translates into more referrals and repeat business.

Radon Testing

Radon testing has been one of the most requested add-ons. Clients are often unaware of radon risks until it’s brought to their attention, and offering this service positions us as a proactive and health-conscious partner in the home-buying process.

Water Quality Testing  

Particularly popular in rural or well-water areas, this service reassures clients about their water safety.

Thermal Imaging

Great for identifying moisture intrusion, heat loss, or electrical issues, thermal imaging is an excellent upsell and helps provide a “wow factor” to clients.

Mold Inspections
and Indoor Air Quality 

Mold inspections have been highly beneficial, especially for clients with sensitivities or concerns about indoor air quality. This service complements our standard inspections by addressing hidden environmental hazards that aren’t always apparent during a general inspection.

Chimney Inspections 

Chimney inspections have proven to be incredibly valuable. Many clients don’t think to check the condition of a chimney, but issues like cracks, blockages, or creosote buildup can pose serious safety hazards. Offering this add-on provides peace of mind to homeowners and buyers alike, while also filling a niche that many inspectors overlook.

Sewer Scope Inspections

Sewer scope inspections have become a standout service. By identifying potential sewer line issues early,
we save our clients significant repair costs and headaches. Real estate agents often recommend this add-on because it addresses a common pain point
in transactions.
