Home Inspector Secrets: The Smallest Issues That Can Lead to Big Repairs

When you’re buying or maintaining a home in Metro Atlanta, it’s often the big-ticket items that grab your attention—HVAC systems, roofs, foundations. But as a Certified Master Inspector® serving homeowners throughout Marietta, Roswell, Smyrna, Sandy Springs, Kennesaw, and the greater Atlanta area, I’ve seen it all. And here’s the truth:

It’s often the tiniest details that lead to the most expensive repairs.

Let me take you behind the scenes of a home inspector’s thought process. These small issues might seem like nothing during a walkthrough—but left untreated, they grow into headaches that can cost thousands to fix.

Let’s look at the top sneaky culprits I find during home inspections in Georgia homes—and how to spot them early.

Hairline Foundation Cracks: Small Shift, Big Problem

A little hairline crack in your concrete foundation might seem harmless. In fact, many Marietta homeowners shrug it off. But even tiny cracks can allow moisture to seep in, which is especially dangerous in Georgia’s humid subtropical climate.

Why It Matters:

• Water penetration leads to mold, rot, and foundation settling.

• Cracks can widen with freeze-thaw cycles or improper drainage.

• If termites are nearby, they’ll use foundation cracks as highways into your home.

🔍 Inspector’s Tip: If I see a 1/16” crack near a corner of the foundation or near a window/door, I look for nearby grading issues, poor downspout drainage, or settlement. It’s not just the crack—it’s what it leads to.

Rust on Metal Gas Line Supports or A/C Disconnects

You’d be surprised how often I point out a rusted gas line clamp or A/C shutoff box during home inspections in places like Decatur and Sandy Springs. Homeowners think, “It’s just surface rust.” But that corrosion can spread, weakening support brackets, conduit, and even gas fittings.

Consequences:

• Structural support fails, leading to unsafe gas lines or disconnected power.

• Code violations if corrosion eats through protective sleeves.

• Advanced rust can mean a full line or component replacement—not cheap.

Missing Kickout Flashing: Invisible Until It’s Too Late

Kickout flashing is a small piece of metal where your roof edge meets the siding. It redirects water away from the wall and into the gutter. When it’s missing? Water can run behind stucco or siding—and it can rot the sheathing inside your walls.

This is one of the most commonly missed defects on newer “move-in ready” homes in Atlanta subdivisions.

What I See:

• Staining on interior drywall with no visible leak source.

• Buckling siding near a roof-wall intersection.

• Mold growth hidden behind walls.

Minor Plumbing Leaks: Drips That Add Up

Tiny leaks under sinks or at the base of toilets are easy to miss—until you find soft flooring or visible mold in the cabinet.

Especially in older Marietta homes, I find:

• Leaking wax rings at toilets.

• Loose P-traps under bathroom sinks.

• Small copper pinhole leaks from corrosion or galvanic reaction.

Why Small Leaks Are Dangerous:

• They create conditions for mold, especially in closed areas like vanity cabinets.

• They rot subflooring, which means costly repairs when floors feel spongy.

• They often go unnoticed for months because they aren’t visible during daily use.

Improper Dryer Venting: Lint = Fire Hazard

One of the smallest but most dangerous issues I regularly find in Georgia homes is improper dryer venting. Sometimes the dryer vents into the crawlspace. Other times, it’s an accordion-style flex hose full of lint.

The Fallout:

• Lint buildup = fire risk.

• Humidity dumped into attics or crawlspaces can cause mold growth.

• Code violations and high moisture near framing.

If I catch this during a routine home inspection in Roswell or Smyrna, I immediately recommend rerouting and cleaning.

Missing or Incomplete Vapor Barriers in Crawlspaces

This one’s huge in Georgia, where high humidity is the norm. A crawlspace without a vapor barrier (or with a torn one) allows moisture to rise from the ground, feeding mold, mildew, and wood rot.

What Starts Small:

• Slightly musty smell in the home.

• Condensation on HVAC ducts or joists.

• Mold blooms under insulation—only visible during a proper crawl.

Loose Toilets and Wobbly Fixtures

It’s easy to overlook a slightly wobbly toilet or a loose faucet. After all, it still works, right?

But over time:

• A wobbly toilet can break its wax seal, leading to sewer gas leaks and subfloor damage.

• Loose fixtures can lead to hidden leaks behind walls or under cabinets.

• Constant motion strains plumbing connections and can lead to ruptures.

This is especially important in homes with older CPVC or PEX connections, which are more prone to expansion-related failures.

Small Roof Nail Pops: Just One Exposed Shingle Nail

In Atlanta, I often see nail pops where a roof nail has worked its way up through the shingle. It’s a tiny defect—barely noticeable from the ground. But here’s why it matters:

• It creates a path for water to seep under the shingle.

• Freeze/thaw cycles and wind-driven rain make it worse.

• Over time, water intrusion can rot the roof decking.

Even newer construction homes in areas like Kennesaw and Sandy Springs often have this defect after their first year due to shifting and settling.

Inadequate Attic Ventilation: Silent Moisture Buildup

Ventilation seems boring until your roof decking is covered in mold. A hot, humid attic is a breeding ground for mildew, wood rot, and insulation degradation.

And it all starts with:

• Blocked soffit vents.

• Undersized ridge or gable vents.

• Poorly designed rooflines that trap hot air.

If your attic feels like a sauna, there’s a problem—even if you don’t see it yet.

Cracks in Grout and Caulking Around Wet Areas

This is one of the most overlooked issues during walkthroughs and open houses. A small crack in shower caulk or missing grout line in a tile floor seems purely cosmetic… until water starts soaking behind your walls or under tile.

What Can Happen:

• Mold and mildew in the wall cavity.

• Soft subflooring, which leads to tile cracking and costly floor replacements.

• Wet drywall or framing, invisible until major repairs are needed.

The Common Thread: It’s Never “Just a Small Issue”

In the world of home inspections, everything is connected. What starts as a tiny imperfection—a loose fixture, a hairline crack, or a rusty bracket—can reveal larger systemic problems.

At Reynolds Home and Property Solutions, we don’t just inspect homes—we help protect your future investment by spotting the small stuff before it becomes a big deal.

Real-World Example: The $12,000 Shower Leak

A homeowner in East Cobb ignored a cracked grout line and small musty smell for over a year. By the time I was called in, water had migrated under the shower pan, rotted out the subfloor, and caused structural damage to the joists. The repairs? Over $12,000.
