When you book a general home inspection, you may also see options for radon, sewer lines, termites, mold, water, septic systems and pools. The useful question is whether an extra service answers something important about the particular home you are buying.
A visual inspection cannot measure radon or show the inside of a buried pipe. A sewer camera does not evaluate a septic system, and a mold sample does not explain why water is entering a house. Ask what the property has, which records are available and what you need to know before your Nashville purchase deadline.
These are seven questions buyers ask about inspection add-ons, with a direct answer and a sensible next step for each.
Before you book
Choose the test that answers a question about this home.
1 Do I need a radon test when buying a Nashville home?
Radon has no reliable visible sign. The EPA advises buyers to know the indoor radon level of a home they are considering, including a newly built home. If the seller has a result, ask for the date, the level tested and the test conditions. A past result may not answer your question if the home was renovated or you plan to use a lower level that was not tested.
Radon testing is a separate measurement, so confirm its timing and when you will receive the result. Ask how the device will be placed, what conditions must be maintained and how an existing mitigation system will be handled. MYCHI's radon guide explains the subject in more detail.
2 Is a sewer scope included in a standard home inspection?
Usually, no. A general inspection can check visible plumbing and observe how fixtures drain, but it cannot show the inside of the buried main sewer line. A sewer scope uses a camera to look at the accessible portion of that line and may document visible restrictions, roots or damage.
Ask about it if there have been backups or slow drains, if the line is older or its history is unknown, or if mature trees and the buried line raise a question. You can also ask for the information without a visible symptom. Confirm where the camera can enter and how any portion it cannot reach will be reported. MYCHI has a separate guide to sewer-scope clues.
3 Should I add a termite or WDO inspection?
Ask about a focused termite and wood-destroying organism inspection if you have seen suspect wood, the seller reports earlier treatment, or your transaction calls for a specific pest report. A general inspector may note damaged wood, but that does not answer every question about organism activity.
The separate service looks for visible evidence of activity, damage and supporting conditions in accessible areas. Ask what report you will receive, whether evidence appears current or historical and what areas could not be checked. A visual WDO inspection cannot guarantee that concealed spaces are free of activity.
4 Do I need mold testing if I smell mustiness or see a stain?
Those observations justify a closer look at moisture. Tell the inspection team where you noticed the odor or stain, whether it changes after rain and what the seller has disclosed. Ask what a mold and moisture evaluation would cover and whether the moisture source needs a separate specialist.
Do not assume every visible spot requires an air test. The EPA says sampling is often unnecessary when mold growth is already visible. If sampling is proposed, ask what question the result will answer and what decision it would change. A sample from one location cannot describe every concealed surface in the house.
5 Should I test the water if the home has a private well?
Yes, discuss recent well-water records and a test suited to the property. The EPA recommends annual testing of private wells for basic indicators including coliform bacteria, nitrates, total dissolved solids and pH. If records are missing or there is a specific concern, ask what water-quality panel will answer it. Municipal-water homes can have specific plumbing or water questions too.
Confirm the exact parameters, sampling method and laboratory turnaround before booking. A test for one contaminant does not establish the condition of everything in the water. The panel and the water source matter more than the generic label 'water test'.
6 Should I get a septic inspection if the home has a septic system?
Yes, a separate septic evaluation is worth discussing before buying a property with onsite wastewater treatment. Obtain maintenance and pumping records if available. Ask what accessible tank components and visible drain-field conditions the selected service covers, and tell the provider about any reported backups, odors or unusually wet ground.
Much of the system is underground, so a visual inspection has limits. Tank access, covers and site conditions affect what can be evaluated; pumping is not automatically part of the inspection. Ask whether a septic contractor needs to perform separate work and how unobserved components will be described.
7 Does a home inspection cover the pool or spa?
Do not assume it does. If a pool or spa is part of the sale, ask whether it is included in the general agreement or requires a focused service. MYCHI's Nashville page lists pool and spa inspection among its specialty options, subject to property and scheduling availability.
Ask whether the proposed scope includes accessible pumps, filters, heating equipment, visible structure and safety features, and whether the system must be operating. A cover, seasonal shutdown or unavailable equipment can limit the result. Confirm how those limitations will be recorded.
How do I decide which extras to book?
Start with the property. A home connected to municipal sewer without a pool does not need septic or pool inspection. A house with a private well and onsite wastewater system raises different questions. List the systems, the records you have and the concerns you want answered, then discuss the matching services with the provider.
Ask for the full quote and when each result will arrive. Some services may require different access or timing. If a finding calls for a specialist, your agent can help you check the purchase agreement's deadlines before you decide what to do next.
Frequently asked questions
Are add-ons included in the quoted home inspection price?
Do not assume they are. Ask for a written quote that names the general inspection and each separate test or specialty service you choose, along with the expected reports and timing.
Can all the tests be done on the same day?
Some services can often be coordinated, but equipment, access, sampling and laboratory turnaround vary. Confirm the appointment plan and result date for each service.
What if I do not know whether the home uses sewer or septic?
Ask the seller or agent for the utility and wastewater details before choosing a sewer scope or septic inspection. Tell the provider what remains uncertain so the correct service and access can be discussed.
