A general home inspection covers a lot of ground—but it doesn’t catch everything. That’s where specialized inspections come in. These targeted evaluations dig deeper into specific concerns that could affect your health, safety, or investment. While not always required, they’re often worth considering—especially in certain climates, property types, or real estate situations.
Let’s break down what specialized inspections are, why they matter, and when you should consider booking one.
What Are Specialized Inspections?
During a standard home inspection, we assess the visible, accessible areas of a property—from the roof to the foundation. But we don’t test for environmental hazards, underground plumbing issues, or the presence of pests unless they’re obvious. Specialized inspections are performed by trained professionals using additional tools, methods, or lab testing to uncover hidden risks.
Think of it this way: the general inspection is your broad overview. Specialized inspections are your deep dives.
Why General Inspections Aren’t Always Enough
Even the most thorough general inspection has limitations. We don’t dismantle HVAC systems, dig up pipes, or test indoor air quality. That’s not a flaw—it’s a boundary set by industry standards, safety concerns, and time.
But sometimes, what you can’t see is just as important as what you can. For example:
- Mold can thrive behind walls or under flooring.
- Radon is odorless and invisible but can cause serious health issues.
- Sewer lines might be cracked or blocked, especially in older homes.
If your general inspection raises red flags—or if you just want peace of mind—specialized inspections can give you clarity before you finalize a purchase or plan repairs.
Common Types of Specialized Inspections
Let’s take a closer look at a few of the most requested specialty inspections in Southern California.
1. Mold Inspections
What they check:
A mold inspection identifies the presence of mold in the home, especially in areas with high moisture—like bathrooms, attics, basements, and around plumbing.
When to consider it:
- You see discoloration on walls or ceilings.
- The home smells musty.
- The inspection report noted leaks, water stains, or high humidity.
- Anyone in the household has allergies or respiratory issues.
Why it matters:
Mold can cause structural damage and health problems. It’s not always visible, and testing can detect spores in the air or hidden growth behind surfaces.
2. Radon Testing
What it checks:
Radon is a naturally occurring gas that enters homes through the ground. Long-term exposure can increase the risk of lung cancer.
When to consider it:
- You’re buying in an area known to have radon issues (yes, even in parts of California).
- You want to be proactive about indoor air quality.
- You’re purchasing a home with a basement or crawlspace.
Why it matters:
Radon is the second leading cause of lung cancer in the U.S. Testing is the only way to know if levels are elevated. If they are, mitigation systems can be installed to vent the gas safely outdoors.
3. Sewer Line Inspections
What they check:
Using a camera, professionals inspect the main sewer line from the house to the street to check for cracks, clogs, roots, or deterioration.
When to consider it:
- The home is older (especially pre-1970s).
- You notice slow drains or sewage smells.
- The property has mature trees near the sewer line.
Why it matters:
Sewer repairs can cost thousands. A quick video inspection can reveal hidden issues and save you from a major post-purchase headache.
4. Termite and Wood-Destroying Organism (WDO) Inspections
What they check:
These inspections look for active infestations or damage from termites, carpenter ants, wood-boring beetles, and fungus.
When to consider it:
- You live in a high-risk area (like coastal or wooded parts of San Diego County).
- The home has wood framing, decks, or fences.
- You see signs like mud tubes, droppings, or soft wood.
Why it matters:
Left untreated, termites and other wood-destroying pests can compromise the structural integrity of a home.
5. Roof Certifications
What they check:
A licensed roofing contractor inspects the roof and provides an estimate of its remaining lifespan, sometimes with a written certification.
When to consider it:
- The roof is aging but still intact.
- You need documentation for a lender or insurance.
- You want confirmation the roof will hold up after closing.
Why it matters:
Some lenders require proof the roof has 2–5 years of life left. Even if they don’t, it’s good to know what kind of expense you might face down the road.
How Specialized Inspections Fit Into the Process
You don’t have to schedule all these inspections right away. In many cases, a general home inspection will point out signs that something needs a closer look. Your inspector may recommend a specialist if they see:
- Signs of past water intrusion
- Evidence of pests or wood damage
- Unusual odors or discoloration
- Roofing concerns that aren’t fully visible
Specialty inspections are usually scheduled during the contingency period—just like the main inspection. The sooner you book them, the more time you’ll have to interpret the results and negotiate if needed.
Are They Worth the Cost?
We get this question a lot. The answer depends on the property and your risk tolerance.
A sewer scope might cost $250–$350. A radon test could run around $150–$200. In the grand scheme of a home purchase, these are small prices to pay to avoid massive repair bills or health risks.
Think of specialty inspections as insurance. If everything comes back clean, you have peace of mind. If something is found, you have options—repair requests, credits, or walking away from a potentially bad deal.
