Home inspections play a crucial role in keeping your property safe, saving you money, and maintaining its value. As a real estate investor and landlord for 24 years, I've witnessed countless inspection reports revealing surprising issues. 

In fact, a recent survey found that 86% of homebuyers discover problems that need fixing through these reports. Knowing what inspectors look for can help you avoid costly surprises and keep your home in top shape. 

This knowledge empowers you to spot potential issues early, saving you time, money, and stress in the long run. Regular maintenance based on these insights can prevent small problems turning into major headaches.

In this article, we'll cover 23 areas of your house that often cause trouble during inspections. We'll discuss common problems, why they matter, and what you can do to address them. 

Let's get started with our home inspection tour! 

Plumbing Leaks and Issues

Plumbing problems can lead to water damage, mold growth, and high water bills. Common issues include leaking pipes, low water pressure, and outdated materials. 

Regular inspections help catch small leaks before they become big problems. Fix drips promptly and consider upgrading old pipes to prevent future issues. In my decade as a real estate investor, I've seen my share of plumbing nightmares.

Gutter and Downspout Blockages

Clogged or improperly installed gutters can cause water damage to your home's foundation and exterior. Look out for clogs, improper slopes, and loose attachments. Clean your gutters regularly, especially after fall when leaves accumulate. 

Ensure they're properly attached and angled to direct water away from your house. This simple maintenance can prevent costly water damage and preserve your home's structural integrity.

Foundation Cracks and Settling

Your home's foundation supports everything above it, making its condition critical. Watch for visible cracks, settling, and moisture intrusion. Small hairline cracks might be normal, but wider or growing cracks need professional attention. 

Ensure proper drainage around your house to prevent water accumulation near the foundation. Address any issues promptly to avoid more serious structural problems down the line.

Electrical Hazards

Faulty electrical systems pose significant safety risks, including fire hazards. Common problems include outdated wiring, overloaded circuits, and non-grounded outlets. 

If you notice flickering lights, frequent circuit breaker trips, or warm outlets, it's time to call an electrician. Regular inspections and upgrades as needed keep your electrical system safe and efficient, protecting your home and family.

Roof Damage

A compromised roof can lead to leaks, structural damage, and decreased energy efficiency. Keep an eye out for missing or damaged shingles, leaks, and aging materials. Inspect your roof regularly, especially after severe weather. 

Replace damaged shingles promptly and consider a full replacement if your roof is nearing the end of its lifespan. A well-maintained roof protects your entire home.

HVAC System Failures

An inefficient heating, ventilation, and air conditioning (HVAC) system affects comfort and increases energy costs. Dirty filters, outdated systems, and improper installation are common culprits. 

Schedule regular maintenance and replace filters every few months. A well-maintained HVAC system runs more efficiently, lasts longer, and keeps your home comfortable year-round.

Insulation Deficiencies

Inadequate insulation results in energy loss and increased utility bills. Check for insufficient or damaged insulation, especially in the attic and walls. 

Good insulation keeps your home warm in winter and cool in summer. Adding insulation to key areas can significantly improve your home's energy efficiency and reduce your heating and cooling costs.

Window and Door Problems

Windows and doors impact energy efficiency and overall home security. Look for drafts, broken seals, and improper installation. Check for air leaks around frames and ensure all locks work properly. 

Fixing these issues improves your home's comfort, reduces energy bills, and enhances security. Consider upgrading to energy-efficient models if your windows and doors are old or in poor condition. 

Flooring Problems

Flooring issues can signal water damage, wear and tear, or structural problems. Look for warping, cracking, and uneven surfaces in all types of flooring. Pay special attention to areas around toilets, sinks, and exterior doors where water damage is common. 

Squeaky floors might indicate loose subfloor or joists. Address any issues promptly to prevent further damage and ensure safe walking surfaces. Regular cleaning and maintenance can extend the life of your floors and help you spot problems early.

Chimney and Fireplace Deficiencies

A poorly maintained chimney or fireplace poses fire hazards and carbon monoxide risks. Common issues include creosote buildup, cracks, and improper ventilation. Schedule yearly cleaning and inspections from a certified chimney sweep. 

They'll check for blockages, damage to the flue lining, and ensure proper ventilation. Don't use your fireplace if you suspect any problems. Proper maintenance keeps your cozy fires safe and enjoyable.

Attic Ventilation and Moisture Issues

Proper attic ventilation prevents moisture buildup and mold growth. Check for signs of water damage, inadequate insulation, and poor airflow. Ensure your attic has sufficient intake and exhaust vents. 

Good ventilation helps regulate temperature, reduce energy costs, and extend the life of your roof. Address any moisture issues immediately to prevent mold growth and structural damage.

Basement and Crawl Space Moisture

Damp basements and crawl spaces can lead to mold and structural issues. Look for water intrusion, musty odors, and signs of mold growth. Ensure proper drainage around your home's foundation. 

Use dehumidifiers to control moisture levels in these areas. Fix any leaks or seepage points promptly. Keeping these spaces dry protects your home's structure and improves indoor air quality.

Appliance Malfunctions

Built-in appliances should work properly and be correctly installed. Check for leaks, unusual noises, or inefficient operation in your dishwasher, oven, and other built-ins. Ensure all appliances are properly vented and have correct electrical connections. 

Perform regular maintenance like cleaning filters and checking hoses. Properly functioning appliances improve your home's efficiency and safety.

Sewer Line Issues

Problems with sewer lines can cause backups, unpleasant odors, and health risks. Watch for slow drains, gurgling toilets, or sewage odors. Tree roots can intrude into pipes, causing blockages and leaks. 

Consider a camera inspection of your sewer line, especially if your home is older. Prompt attention to sewer issues prevents costly and messy backups.

Deck and Porch Integrity

Outdoor structures need to be safe and secure for regular use. Inspect for rotting wood, loose railings, and unstable foundations. Ensure proper attachment to the house and adequate support. Check for protruding nails, splintering wood, and wobbly stairs. 

Regular maintenance like cleaning and sealing can prolong the life of your deck or porch. Safe outdoor spaces enhance your home's value and your family's enjoyment.

Pest Infestation Signs

Pests can cause significant damage and health risks if not addressed promptly. Look for droppings, chewed wood or wires, and unusual noises in walls. Check for termite mud tubes along foundations and wood structures. 

Keep food in sealed containers and fix any moisture problems that attract pests. For more tips on dealing with pests safely, read our article 'Get Rid of Pests Quickly Without Harsh Chemicals’.

Driveway and Walkway Damage

Cracked or uneven surfaces can be hazardous and impact your home's curb appeal. Inspect for cracks, shifts, and drainage problems in these areas. Fill small cracks promptly to prevent water intrusion and further damage. 

Ensure proper slope for water drainage away from your house. Safe, well-maintained walkways and driveways enhance your property's safety and appearance.

Staircase and Railing Safety

Stairs and railings must meet safety standards to prevent accidents. Check for loose railings, uneven steps, and missing handrails. Ensure proper lighting on all staircases. 

Fix any wobbly balusters or loose treads immediately. Proper maintenance of these areas is crucial for your family's safety and may be required by local building codes.

Exterior Wall and Siding Issues

Your home's exterior protects its weather and contributes to its structural integrity. Look for cracks, rot, and missing or damaged siding. Check for peeling paint, which can lead to wood rot. Ensure proper caulking around windows and doors. 

Regular cleaning and maintenance of your siding can prevent water intrusion and extend its lifespan. Well-maintained exterior walls improve your home's appearance and energy efficiency.

Garage Safety Concerns

Garages often have electrical components and structural elements that can pose risks. Ensure proper wiring and ventilation, especially if you have an attached garage. Test your garage door opener's safety features regularly. 

Check for any signs of moisture or pest intrusion. A safe, well-maintained garage protects your vehicles and can serve as valuable additional space for your home.

Smoke and Carbon Monoxide Detector Compliance

These detectors are essential for safety and often require local codes. Test all detectors monthly and replace batteries twice a year. Ensure you have detectors on every level of your home and outside sleeping areas. 

Replace units every 10 years or as recommended by the manufacturer. Properly functioning detectors can save lives in case of fire or carbon monoxide leaks.

Radon Levels

Radon is a colorless, odorless gas that can seep into homes from the ground and poses serious health risks. Conduct a radon test, especially in basements or lower levels. If levels are high, install a radon mitigation system. 

Retest periodically to ensure levels remain low. Addressing radon concerns protects your family's long-term health and is often a concern for potential buyers.

Environmental Hazards (Lead Paint, Asbestos)

Older homes may contain hazardous materials like lead paint and asbestos. These pose significant health risks, especially during renovations. If your home was built before 1978, assume it contains lead paint unless tests prove otherwise. 

Asbestos may be present in old insulation, flooring, or siding. Hire certified professionals for testing and any necessary removal or encapsulation. Proper handling of these materials is crucial for your family's safety.

Keep Your Home Inspection-Ready

Staying on top of these 23 areas helps keep your home safe, efficient, and valuable. Regular maintenance and prompt attention to issues can prevent small problems growing into costly repairs. 

With this knowledge, you're well-equipped to keep your home in top shape. Stay proactive, address problems promptly, and don't shy away calling in the experts when needed. 

Remember, a well-maintained home not only passes inspections with flying colors but also provides a comfortable and secure environment for you and your family.
