8 Most Common Home Inspection Issues

When purchasing a house, a professional home inspection can be a game-changer when it comes to making important decisions. They can help you find common and hard to see issues to avoid costly repairs down the road. 


The process of buying a home can be extremely daunting and you may encounter a variety of unexpected hurdles. Making sure that a property is meticulously inspected by a professional home inspector is one effective way to ensure that you’re making a sound investment. Professional home inspection companies like AA Home Inspections are trained to identify various issues that may be latent in a home. However, it may help to become acquainted with several problems that are more common than others.

Here are eight common home inspection issues identified during professional home inspections:

  1. Roof damage
  2. Plumbing problems
  3. Electrical issues
  4. Mold and mildew
  5. Water damage
  6. Foundation problems
  7. Heating and cooling issues
  8. Pest infestation

In order to identify any of these issues, a thorough home inspection is highly recommended. Usually, the corresponding solutions include repairs or replacements. Although not all of these issues are deal breakers, they can equip you with a better understanding of the property’s overall condition. This article covers the eight most common issues identified during AA Home Inspections.

 If you are currently on the market to buy a home, make sure you don’t arrive at a decision before conducting a home inspection. In fact, for any prospective home buyer, a professional home inspection is a great way to identify any potential problems and to understand what exactly they are getting into.

1. Roof damage

One of the most common issues identified during home inspections is roof damage. There are several factors that can contribute to this issue, including age, weather, and poor maintenance. Roof damage often snowballs into other bigger issues, such as leaks. As such, it’s important to fix this issue as soon as possible.

Unfortunately, in certain cases, inspecting a roof may be easier said than done. For instance, steep roofs can be a missed opportunity for many home inspectors to find potential problems, as they can be dangerous to access, let alone inspect. AA Home Inspectors utilize drone technology to obtain an unobstructed view of typically inaccessible areas, resolving this seemingly challenging hurdle. 


2. Plumbing problems

Let’s all admit it – plumbing problems can be a pain to navigate. While it may seem tempting to ignore them, they will only deteriorate over time. This is why it’s very important to fix plumbing issues as soon as they are identified. These can range from leaks to clogged drains and everything in between. When a home undergoes inspection, it’s highly important for inspectors to thoroughly check all the plumbing to make sure unexpected issues do not emerge in the future. 

 While discussing plumbing issues, it is also necessary to point out that certain problems, like a clogged toilet or a leaky sink, are easy to spot, while a few others are silent killers. For instance, certain larger, more serious issues like drainage or slow leaks can often go undetected until they become a bigger problem.

 Another common issue that is often identified during professional home inspections is outdated plumbing. Old pipes can accumulate rust and become brittle, leading to leaks and other problems. If you haven’t changed your plumbing in years, it may be time to get it checked by a professional to ensure that it’s legal, compliant with regulations, and in good working condition.

 For instance, Polyethylene (PE) pipes are only permitted for household use in the United States when it comes to water pressure tanks and main water turn-off valves, whereas polybutylene (PB) pipes are prohibited for household usage across the US, since August 2010.


3. Electrical issues

Home inspectors are also invaluable in mitigating major hazards associated with electrical issues. According to a 2017 National Fire Protection Agency study, electrical distribution, lighting, and power transfer equipment were involved in 57 percent of home structure fires between 2010 and 2014.

Some common electrical problems that your home inspector may find are:

 In particular, poorly installed or outdated electrical wiring can pose serious fire hazards. Thus, it is pertinent to address such electrical problems as soon as possible. Please note that, in the United States, all electrical work must adhere to National Electric Code (NEC), which has been revised 17 times since 1975.

Thus, very old or ancient houses might be equipped with electrical systems that no longer meet the NEC’s current standards. This is another reason why opting for a professional home inspection before making a purchase is crucial.

4. Mold and mildew

We all know that mold and mildew can cause a variety of health problems and moisture-prone areas are highly conducive for their growth. As such, they are most commonly found in the bathroom, kitchen, or basement. To check for mold, an inspector will come and collect samples, which is a vital step when determining its presence (or absence, if you are lucky).

 To check for mold spores, air samples are tested by using a pump that goes into a collection device to catch spores, which are then subjected to a thorough lab analysis.

 The severity of the issue is also determined through these results. Once remediation efforts are completed, the inspector collect samples again to confirm the removal of all traces of mold.

 Mold and mildew can cause respiratory problems, allergies, and skin irritation, so it’s important to have any affected areas cleaned and repaired. Even if your home is free from these pesky issues, a professional home inspector will be able to identify any areas susceptible to mold and mildew and ensure that they are properly cleaned and repaired.

5. Water damage

Water damage is one of the most common problems detected during home inspections, and it can be caused by various things, from leaks to floods. Water damage can lead to a variety of other problems, like mold and mildew, so it must be addressed in a timely manner.

Professional home inspectors check for visible signs of water damage by looking for: 

  • Stains on ceilings or walls
  • Warping
  • Odors
  • Peeling or cracked paint, or
  • Evidence of mold or mildew

6. Foundation problems

One of the telltale signs of a foundation problem is cracks in the walls or floors. If you find such cracks in your own home or during the buying process, it is a sign that you need an expert to professionally inspect the house. This is because cracks can be caused by a variety of things, from settling to structural problems. Foundation problems can also cause doors and windows to stick or not close properly.

 Regular home inspections can help identify any potential foundation problems before they worsen into a larger issue. In addition to cracks on walls and floors, here are a few other indicators of potential foundation issues: 

  • Cracks in the foundation
  • Doors or windows that stick or don’t close properly
  • Gaps around doors or windows
  • Water stains on the ceilings or walls
  • Warping floors

A professional home inspector can identify any of the aforementioned signs and delve into a deeper analysis to determine if the house has any foundation-based problems. They will also recommend the best course of action.

7. Heating and cooling issues

The heating, ventilation, and air conditioning (HVAC) system is one of the most important systems in a home. No matter what the season or weather, it’s keeps the home comfortable year-round. This is why it must be in good working condition.

Some common HVAC problems that are found during home inspections include: 

  • Dirty air filters
  • Improperly sized HVAC unit
  • Leaking ductwork or other ductwork problems
  • Exhaust system issues
  • Condenser unit issues
  • Dirty or clogged coils

 Home inspections can help identify any potential HVAC problems so that they can be repaired before they become bigger issues or catch you unaware after you make the purchase.

8. Pest infestation

Pests like termites, ants, and rodents can cause various problems in a home, from damaging the structure to adversely affecting your health. Some pests are also capable of starting fires, so it’s important to eliminate any pest infestations as soon as they catch your attention.

 A professional home inspector will look for signs of pests, like droppings, damage, or nests. Additionally, they are also equipped to identify potential pest entry points located throughout a house, recommend sealing solutions, and find live and dead insects or rodents.

It is important to remember that some infestations are worse than others. Termites are one of the most destructive pests and can cause extensive damage to a home’s structure. Termite infestations are notoriously difficult to detect, so it’s important to have a professional home inspector look for signs of termites during an inspection.

Final Inspection

A home inspection is a crucial part of the home-buying process, as it can help identify any potential problems with the home so that they can be repaired before you move in.

While some common issues, like water damage, can be repaired relatively easily, others, like foundation problems, can be much more expensive to fix. In the long run, you can save you a lot of time, money, and stress by hiring a professional home inspection company like AA Home Inspection to check for these eight (and many other) potential issues.
