14 Common Problems Found During Home Inspections
Home inspections rarely come back without findings. Common issues include minor plumbing leaks, electrical concerns, roof damage, HVAC problems, window issues, and signs of water intrusion. Most aren’t dealbreakers, but a few can lead to real repair costs or a follow-up inspection from a specialist.
Even homes that appear well-maintained often have issues that aren’t visible during a showing. Understanding what typically appears on an inspection report helps buyers make confident, informed decisions. Below are 14 of the most common issues home inspectors uncover and what buyers should know about each one.
What is a Home Inspection?
A home inspection is a detailed visual assessment of a property conducted by a licensed home inspector after a buyer goes under contract. The inspector examines major systems and components, including the roof, HVAC, plumbing, electrical, attic, appliances, and structure, to identify defects, safety issues, and general wear.
The final inspection report provides buyers with a clear picture of the home’s condition. It’s not a code compliance evaluation, nor does it guarantee that every problem will be found, but it’s an essential tool for understanding what repairs or future expenses may be needed. If you’re still deciding whether to have one done at all, our guide to whether home buyers have to get a home inspection covers what’s required, what’s recommended, and what happens if you skip it.

Most Common Home Inspection Findings
Below are the 14 issues that most frequently appear on inspection reports. Some are inexpensive to correct, while others may require a licensed professional. In many cases, these findings shouldn’t scare buyers away; they’re simply part of owning a home.
1. Dirty AC Coils
Dirty or clogged air-conditioning coils are among the most routine findings in Florida. When coils are covered in dust or debris, the HVAC system becomes less efficient and may struggle to maintain temperature. This can lead to higher utility bills and additional wear on the unit. Fortunately, cleaning coils is a straightforward maintenance task that HVAC companies perform quickly and affordably.
2. Missing Anti-Tip Bracket on Range
Most modern ranges come with an anti-tip bracket, yet many homeowners never install it. This small metal device prevents the oven from tipping forward if weight is placed on the open door, a safety feature that matters most in homes with children or pets. Home inspectors flag this regularly, and installation usually takes just a few minutes.
How serious is it? Minor to fix, but worth addressing promptly since it’s a genuine safety item.
3. No Auto-Closure on Interior Garage Door
Depending on the home’s construction and applicable code, the door leading from the garage to the interior may be expected to close automatically, helping create a protective barrier in case of fire and reducing the risk of carbon monoxide entering the home. Home inspectors often find that the hinges are worn or out of adjustment, causing the door to remain open. The fix is typically simple, adjusting or replacing the hinge.
How serious is it? Usually a quick, inexpensive fix, though worth confirming what’s required for your specific home.
4. Missing or Cracked Caulk
Cracked or missing caulk is extremely common around windows, exterior trim, sinks, bathtubs, and showers. Over time, gaps in caulk allow water intrusion, which may lead to wood rot, mold, or compromised seals. Because caulk is inexpensive and easy to apply, this finding is usually considered routine maintenance rather than a major defect.
How serious is it? Minor, but don’t ignore it for too long, since small gaps can lead to bigger water problems.
5. Window Issues
Sticking windows, windows that won’t stay open, broken balances, or fogged panes are all common findings. Functional windows are important for ventilation and safety, especially those used as emergency exits. While some repairs are simple, fogged double-pane glass indicates a failed seal, which may require replacement.
How serious is it? Depends on the issue, a stuck window is a minor fix, but fogged glass usually means full replacement.
6. Electrical: GFCI Not Tripping
GFCI outlets are designed to prevent electrical shock by shutting off power when a fault is detected. When these outlets fail to trip, they are no longer providing proper protection. Inspectors find this frequently in kitchens, bathrooms, garages, and exterior areas. Replacing a GFCI outlet is usually an easy fix for a licensed electrician.
How serious is it? Worth addressing promptly, it’s inexpensive to fix but is a genuine safety protection.
7. Minor Plumbing Leaks
Small leaks, especially under sinks, are one of the most common problems inspectors identify. While these drips don’t usually indicate major plumbing failure, they can cause water damage, cabinet deterioration, or mold if not repaired. Tightening a fitting or replacing a small component often solves the issue.
How serious is it? Usually minor, but don’t leave it unaddressed, since ongoing moisture is what causes the bigger problems.

A running toilet typically results from worn internal parts such as the flapper, fill valve, or float. Although inexpensive to fix, a running toilet can waste a significant amount of water over time. Inspectors routinely recommend addressing this soon after move-in.
How serious is it? Minor and cheap to fix, but worth doing quickly since it adds up on the water bill.
9. Clogged or Slow-Draining Sinks
Hair, soap buildup, food debris, and mineral deposits can clog drains and slow water flow. While this is a routine homeownership issue, a severe blockage may indicate deeper plumbing concerns. Plumbers can typically clear drains quickly, and buyers should treat this as routine maintenance unless other issues are present.
How serious is it? Usually minor, but a severe or recurring clog is worth a plumber’s opinion.
10. Broken or Missing Roof Tiles
Florida roofs endure intense sun, storms, and tree debris, making broken tiles a frequent finding. Even a single cracked tile can allow moisture to penetrate the underlayment. While replacing individual tiles is usually simple, widespread damage may indicate age-related deterioration.
How serious is it? Usually minor if limited to a few tiles, but widespread damage warrants a professional roof inspection.
11. Roof Leaks
Roof leaks are more serious than cracked tiles. Inspectors look for staining in the attic, wet insulation, deteriorated flashing, and soft spots in the roof deck. The extent of damage determines whether a repair or replacement is needed. When leaks are present, buyers should obtain a professional roofing evaluation.
How serious is it? Potentially major, get a licensed roofer’s opinion before deciding how to respond.
12. Wood Rot
Wood rot usually appears around exterior trim, doors, and windows where moisture accumulates. While small sections can often be repaired, significant rot may require replacement of full boards or frames. In some cases, lenders may require repairs before closing, depending on severity and loan type.
How serious is it? Depends on the extent, small spots are routine, but widespread rot can affect financing.
13. Toilet Loose to the Ground
A loose toilet usually indicates a deteriorated wax ring or loose mounting bolts. If not corrected, water can leak beneath the flooring and cause hidden damage. Repairing this is a common request buyers make during negotiations.
How serious is it? Minor to fix, but address it promptly since hidden leaks can cause real damage over time.
14. Insufficient Attic Insulation
Older homes frequently lack the insulation levels recommended today. Poor insulation makes HVAC systems work harder and increases energy bills. While this is not a structural concern, inspectors typically recommend improving insulation for comfort and efficiency.
How serious is it? Minor, an efficiency and comfort item rather than a safety or structural concern.
Are These Findings Dealbreakers?
Most inspection findings are not dealbreakers. In fact, it’s extremely rare for a home inspection to come back “clean.” Almost every home, even new construction, has items that need attention. What matters is understanding whether the issues are:
- minor maintenance items,
- moderate repairs, or
- major concerns requiring a specialist.
A rough way to sort what you’re looking at:
Usually not dealbreakers: minor plumbing leaks, missing or cracked caulk, a running toilet, slow drains, minor window repairs, a missing anti-tip bracket.
Potentially more serious: active roof leaks, significant wood rot, major electrical defects, structural movement, extensive plumbing problems, a failed HVAC system.
Buyers should evaluate the cost, safety impact, and urgency of each finding. Occasionally, findings fall clearly into that second category and a buyer decides not to move forward at all, our guide to why buyers walk away after a home inspection covers what usually drives that decision. If you are early in the buying process, my buyer resources can help you understand how inspections fit into a typical real estate timeline.
Which Home Inspection Problems Can Be the Most Expensive?
Not all findings are created equal, and cost usually depends on how extensive the problem is and whether a specialist needs to get involved. Some of the potentially expensive items include:
- Roof leaks or widespread roof deterioration
- HVAC system failure or end-of-life equipment
- Plumbing system issues beyond small leaks
- Electrical panel defects or outdated wiring
- Foundation or structural movement
If an inspector suspects a major concern, they will recommend a specialized inspection. Buyers should follow those recommendations.
Understanding the Home Inspector’s Limitations
Home inspectors are generalists, not specialists. They visually examine accessible areas but do not open walls or perform repairs. For issues such as roof leaks, electrical concerns, plumbing problems, or HVAC performance, a specialist should be consulted for more detailed repair costs and recommendations. Knowing where those limitations are is easier if you go into the inspection prepared. Our guide to questions to ask a home inspector covers what to ask before, during, and after the inspection.
What Should Buyers Do When a Home Inspection Finds Problems?
Depending on the contract and the severity of findings, buyers typically have several choices after the inspection:
- Request repairs
- Request a credit toward repairs
- Negotiate the purchase price
- Accept the property as-is
- Cancel the contract (if allowed)
Most buyers choose to focus on safety, function, and major repair items rather than small cosmetic issues. Our guide to negotiating repairs after a home inspection walks through how that process typically works.

Should You Fix Inspection Problems Before Closing?
Addressing important repairs before moving in can save money and prevent headaches down the road. Items such as roof leaks, plumbing issues, loose toilets, and clogged drains may seem small but can worsen over time.

Popular Home Inspection Questions
What are the most common problems found during a home inspection?
Common findings include dirty AC coils, minor plumbing leaks, running toilets, window issues, missing safety items like anti-tip brackets, roof tile damage, and signs of wear like cracked caulk or insufficient attic insulation. Most are routine maintenance items rather than major concerns.
What are red flags on a home inspection?
The clearest red flags are active roof leaks, significant wood rot, major electrical defects, structural movement, and extensive plumbing problems. These are the findings most likely to require a specialist, affect financing, or become genuinely expensive if left unaddressed.
Is it normal for a home inspection to find problems?
Yes, and it’s actually rare for one not to. Nearly every home, including new construction, turns up something on the inspection report. What matters is separating routine maintenance items from anything that’s genuinely serious.
What’s included in a home inspection report?
A typical report includes general information about the property, such as its construction and roofing materials, along with photos of problem areas, written descriptions of any defects found, and notes on the condition of major systems like plumbing, electrical, and HVAC. Inspectors will often point out signs of pest activity or water intrusion as well, even though a standard inspection isn’t the same as a dedicated pest or mold inspection.
Should I be worried if my inspection report is long?
Not necessarily. A long report often just means the inspector was thorough, not that the home is in bad shape. Most items on a typical report are minor maintenance notes. The better question is how many items fall into the moderate or major category, not how many pages the report runs.
What should I do if my inspector finds a major issue?
Get a cost estimate from a licensed specialist before deciding how to respond. From there, buyers typically request repairs, ask for a credit, renegotiate the price, or in serious cases, walk away from the deal if their contract allows it.
