Whether you’re buying, selling, or building a home, a professional home inspection is a critical step in the process. But not all issues are created equal. Some findings are minor and easily addressed, while others could signal serious, expensive, or even dangerous problems.
At 4 Wahl Property Inspections, our licensed inspectors perform hundreds of detailed inspections each year across Palm Beach, Martin, and St. Lucie Counties, and we’ve seen it all. In this blog, we break down the top 10 red flags we look for during a home inspection — and what they might mean for your investment.
Whether you’re preparing to sell, about to purchase, or overseeing a new construction, knowing these warning signs can help you make smarter, safer decisions.
1. Roof Damage or Age
A roof that’s leaking, missing shingles, or nearing the end of its life is a major red flag. Repairs or replacement can cost thousands — and an old roof may also impact insurance approval in Florida.
What we check:
- Shingle condition
- Flashing integrity
- Evidence of prior patchwork
- Signs of water intrusion in the attic

2. Foundation Cracks or Shifting
The foundation is literally what your home is built on. Cracks, settlement, or bowing walls can signal structural instability.
Red flags include:
- Horizontal or stair-step cracks
- Uneven floors
- Doors that stick or don’t latch
- Visible gaps in baseboards or walls
These issues may require structural engineering and extensive repairs.
3. Water Damage or Mold
Florida’s humidity makes homes especially vulnerable to moisture damage and mold. We look for signs that might not be immediately visible to the untrained eye.
What we look for:
- Musty odors
- Stains on walls, ceilings, or floors
- Active leaks or past water intrusion
- Mold in bathrooms, attics, and crawl spaces
Mold remediation can be costly — and some types pose health risks.
4. Electrical Problems
Outdated or faulty electrical systems are not only inconvenient — they can be fire hazards.
Top issues we find:
- Double-tapped breakers
- Outdated aluminum wiring
- Exposed wiring or ungrounded outlets
- Improper DIY electrical work

5. Plumbing Deficiencies
From hidden leaks to substandard materials, plumbing issues are a common and costly concern.
Red flags include:
- Low water pressure
- Evidence of past leaks
- Polybutylene or corroded pipes
- Improper drainage
Unchecked plumbing problems can lead to mold, water damage, and major repairs.
6. HVAC System Issues
An older or poorly maintained heating and cooling system can be a money pit — and a comfort issue.
What we check:
- Age and condition of units
- Proper airflow and duct sealing
- Thermostat function
- Signs of condensation or rust
Replacing an HVAC system can cost $5,000 or more, so it’s critical to catch problems early.
7. Termite or Pest Damage
In South Florida, termites are a real threat to wooden structures. During your inspection, we check for signs of wood-destroying organisms (WDOs) even if a separate termite inspection is required.
Signs we spot:
- Hollow wood sounds
- Mud tubes along foundation
- Sawdust-like frass
- Damaged trim, joists, or beams
8. Poor Drainage or Grading
Water should flow away from the home — not toward it. Improper grading can lead to foundation issues, moisture in crawl spaces, or flooding.
What we inspect:
- Grading slope
- Gutter performance
- Downspout extensions
- Evidence of pooling water
🔗 Thinking of selling? Pre-Listing Inspections help you spot issues like these before buyers do.
9. Faulty Windows and Doors
This isn’t just cosmetic. Improperly sealed windows or doors can lead to higher energy bills, water intrusion, and security risks.
Common issues include:
- Foggy or broken seals
- Rotting window frames
- Doors that don’t close flush
- Signs of forced entry
10. Unpermitted Additions or DIY Work
It’s not unusual for us to find unpermitted renovations or poor-quality handyman work that doesn’t meet code. This can affect both your home’s safety and its resale value.
We look for:
- Inconsistent construction
- Non-matching materials
- Absence of permits or paperwork
- Unsafe electrical or plumbing retrofits
If issues are found, sellers may need to disclose them or bring work up to code before a sale can proceed.
Regional Insight: Why Inspections Matter in Palm Beach, Martin & St. Lucie
