No home is perfect. Whether a house is 1 00 years old or newly constructed, a professional home inspection will almost always uncover items worth knowing about.
Some findings are minor maintenance issues, while others can involve safety concerns or potentially expensive repairs. The purpose of a home inspection isn’t to determine whether a house “passes” or “fails.” It’s to give you a better understanding of the property’s condition so you can make an informed decision.
Here are 10 common issues that home inspectors look for during an inspection.
1. Improper Drainage Around the Home
Water is one of the biggest threats to any home.
The ground surrounding a house should generally direct water away from the foundation. Poor grading, clogged gutters, missing downspout extensions, or improperly directed roof drainage can allow water to collect around the foundation.
Over time, this can contribute to basement moisture, foundation deterioration, mold growth, and other problems.
HullSight Pro Tip: After a heavy rainstorm, walk around your property. Standing water near the foundation or overflowing gutters can be an early warning sign of a drainage problem.
2. Roof Deterioration
A roof doesn’t need to be actively leaking to have problems.
During an inspection, we look for conditions such as damaged or missing shingles, deteriorated flashing, exposed fasteners, improper repairs, and signs that roofing materials may be approaching the end of their service life.
Inside the attic, we also look for evidence of past or present moisture intrusion.
3. Electrical Safety Concerns
Electrical defects are particularly important because some conditions can present shock or fire hazards.
Common findings can include improperly wired outlets, missing GFCI protection, damaged wiring, open electrical junction boxes, double-tapped breakers, and modifications that may not have been performed properly.
Older homes may also contain electrical systems or components that deserve additional evaluation.
4. Plumbing Leaks
Even a small plumbing leak can cause significant damage if it goes unnoticed.
Inspectors check accessible supply and drain piping, plumbing fixtures, water heaters, and other visible components for leaks, corrosion, improper installation, and signs of previous water damage.
We also operate representative fixtures to evaluate their basic functionality during the inspection.
5. Foundation Cracks
Finding a crack in a foundation doesn’t automatically mean the home has a serious structural problem.
Concrete and masonry can develop cracks for several reasons, including normal shrinkage and settlement. However, the location, direction, width, displacement, and overall pattern of cracking can help determine whether further evaluation is warranted.
That’s why foundation cracks should be evaluated in context rather than simply labeled as “good” or “bad.”
6. Attic Ventilation and Insulation Issues
The attic can reveal a surprising amount about a home’s overall performance.
Insufficient insulation can contribute to energy loss, while poor ventilation may allow excessive heat or moisture to accumulate.
Inspectors also look for bathroom or dryer exhaust vents terminating improperly in the attic, evidence of roof leaks, damaged framing, and other visible concerns.
7. HVAC Maintenance and Aging Equipment
Heating and cooling systems are some of the most expensive mechanical components in a home.
Common findings include dirty filters, lack of maintenance, damaged ductwork, improper condensate drainage, deteriorated equipment, and systems that may be approaching the end of their expected service life.
Regular maintenance can help improve efficiency and extend equipment life.
8. Exterior Wood Deterioration
Wood exposed to moisture can deteriorate surprisingly quickly.
Areas around windows and doors, exterior trim, decks, porches, and roof edges are particularly susceptible.
Peeling paint, failed caulking, improper flashing, and poor drainage can allow moisture to reach wood components and eventually cause decay.
9. Unsafe Decks, Stairs, and Railings
Deck and stair defects are especially important because they can create immediate safety concerns.
During an inspection, we look at accessible structural connections, guardrails, handrails, stairs, support posts, visible framing, and attachment points.
Loose railings, improper connections, deteriorated framing, and inadequate support are all conditions that may warrant repair.
10. Signs of Moisture Intrusion
If there’s one recurring theme throughout many home inspection findings, it’s water.
Basements, crawlspaces, roofs, bathrooms, plumbing systems, windows, doors, and exterior walls can all be potential sources of moisture intrusion.
Water stains, damaged materials, musty odors, efflorescence, and visible microbial growth can indicate current or previous moisture problems.
Finding the source—not simply covering up the symptom—is key.
Don’t Be Scared by a Long Inspection Report
It’s important for buyers to keep inspection findings in perspective.
A detailed inspection report may contain dozens of observations, but that doesn’t necessarily mean you’re buying a bad house. Many findings are routine maintenance items or relatively straightforward repairs.
The important part is understanding which findings involve safety, significant damage, major systems, or potentially costly repairs and which are simply part of normal homeownership.
A good home inspector should help you understand that difference.
HullSight Pro Tip
Pay particular attention to problems involving water, structure, electrical safety, roofing, and major mechanical systems. Cosmetic defects may be easy to see during a showing, but these less-visible systems can have a much greater impact on the long-term cost and safety of owning a home.
