Home Inspection - Things that fail a Home Inspection

A quick clarification is that a property does not "Pass" or "Fail" a General Home inspection. The goal of a home inspection is not to make a purchase recommendation but to provide home buyers with useful, accurate information that will help make an informed purchase decision.

A home inspection is a comprehensive review of a property's condition, typically conducted by a certified inspector. It aims to identify any issues that could affect the property's value or safety. So, how long does a home inspection take? The process usually takes between 2-4 hours, depending on the property's size and condition. After the inspection, the inspector provides a detailed home inspection report, highlighting any problems found and offering a condition inspection report that outlines the property's current state.


The Importance of Home Inspections and Identifying Things That Fail a Home Inspection

Home inspections are vital for buyers, as they provide a detailed snapshot of the current state of a property. This process helps you understand what you're buying and what repairs or maintenance might be necessary. It's not just about identifying problems; it's about giving you peace of mind and negotiating power. Knowing the condition of the home allows you to make informed decisions, whether it's negotiating the price, asking the seller to make repairs, or deciding to walk away.

Foundation Problems

Foundation Problems - Discover common foundation issues that often lead to inspection failures. Learn how cracks and uneven floors are critical things that fail a home inspection.

Foundation issues can be a major red flag and are often one of the things that fail a home inspection. They can manifest as cracks in the walls, uneven floors, or doors that don't close properly. These issues often indicate underlying structural problems that can be costly to repair. During an inspection, look for signs of foundation settling or shifting, which could lead to significant future expenses.


Common Foundation Issues

Foundation problems can arise due to various factors, including poor construction, soil erosion, or natural wear and tear. Inspectors typically look for:


  • Cracks in the Foundation: Vertical or horizontal cracks can indicate different types of stress. Vertical cracks are often less concerning, whereas horizontal cracks can be a sign of serious structural issues.

  • Uneven Floors: If floors are sloping or uneven, it might be a sign that the foundation is settling or shifting.

  • Sticking Doors and Windows: If doors and windows are difficult to open or close, it could mean the frame is shifting due to foundation movement.

Roofing Issues

The roof is your home's first line of defence against the elements. Common roofing problems, like missing shingles or leaks, often appear in a condition inspection report as critical issues. These problems can lead to water damage inside the home, affecting the structure and interior finishes. An inspector will check for signs of wear and tear, ensuring the roof is in good condition or identifying areas that need repair.


Detailed Roofing Concerns

Roofing issues can vary widely in severity and cost to repair. Common issues include:

  • Missing or Damaged Shingles: This can lead to leaks and water damage. Shingles may be missing due to wind damage or simply old age.

  • Poor Drainage: Clogged gutters or improper drainage can cause water to back up, leading to leaks and potential water damage.

  • Sagging Roof: This can indicate structural issues and should be addressed immediately to prevent further damage.

Plumbing System Failures

Plumbing issues can range from minor leaks to major pipe bursts. During an inspection, the inspector will check for signs of water damage, corrosion, and proper water pressure. Common failures include outdated piping materials and faulty fixtures, which can lead to costly repairs if not addressed promptly.


Plumbing Red Flags

A thorough plumbing inspection will cover:

  • Leaking Pipes: Even small leaks can lead to significant water damage and mold growth over time.

  • Water Pressure Issues: Low water pressure might indicate a blockage or leak in the system.

  • Corroded Pipes: Older homes might have pipes made from materials that corrode over time, leading to leaks and water quality issues.

Electrical System Problems

An outdated or faulty electrical system is a significant safety hazard and one of the common things that fail a home inspection. Inspectors will look for exposed wiring, overloaded circuits, and outdated panels. These issues not only pose a fire risk but can also affect the functionality of modern appliances. Ensuring the electrical system meets current safety standards is crucial for any property.

Electrical Concerns to Address

  • Exposed Wiring: This is a major safety hazard and must be addressed immediately.

  • Outdated Panels: Homes with older electrical panels may not be equipped to handle modern electrical loads, leading to frequent trips or even fires.

  • Improper Wiring: DIY electrical work or outdated wiring can be unsafe and should be corrected by a professional.

HVAC System Concerns

A home's heating, ventilation, and air conditioning (HVAC) system is vital for comfort and energy efficiency. Common issues include inadequate maintenance, old equipment, and poor installation. Inspectors will evaluate the system's age, condition, and efficiency, recommending repairs or replacements if necessary.


HVAC Inspection Points

  • Age of the System: HVAC systems typically last 15-20 years. Older systems may need replacement.

  • Maintenance Records: Regular maintenance is crucial for efficiency and longevity. Lack of maintenance can lead to breakdowns and costly repairs.

  • Ductwork Issues: Leaky or poorly insulated ductwork can lead to energy waste and uneven heating or cooling.

Water Damage and Leaks


Water damage can lead to mold growth and structural issues if left unchecked. Inspectors will look for signs of water intrusion, such as stains on ceilings or walls, musty odors, and visible mold. Addressing these issues promptly can prevent further damage and health hazards.

Recognizing Water Damage

  • Stains and Discoloration: Water stains on ceilings or walls can indicate leaks from the roof or plumbing.

  • Mold Growth: Musty odors or visible mold are signs of moisture problems that need immediate attention.

  • Warped or Soft Flooring: This can be a sign of ongoing water damage, often from leaks or poor drainage.

Pest Infestations

Pests like termites, rodents, and insects can cause extensive damage to a property. An inspection will include checking for signs of infestations, such as droppings, nests, or damaged wood. Early detection and treatment are essential to prevent costly repairs and maintain the property's integrity.

Common Pest Issues

  • Termite Damage: Look for hollow-sounding wood or mud tubes along the foundation.

  • Rodent Droppings: These can indicate an active infestation and should be addressed immediately.

  • Insect Nests: Wasps, bees, or ants can create nests that damage the home's structure.

Structural Deficiencies

Structural issues can arise from poor construction, natural wear and tear, or environmental factors. Inspectors will assess the integrity of the home's framework, looking for sagging floors, cracked walls, or misaligned doors. These deficiencies can affect the property's safety and resale value.

Key Structural Concerns

  • Sagging Rooflines: This can indicate issues with the home's structural integrity and should be evaluated by a professional.

  • Cracked or Bowed Walls: These can be signs of foundation problems or structural stress.

  • Misaligned Doors and Windows: These might indicate shifting foundations or structural issues.

Safety Hazards

Safety hazards can include anything from missing handrails to faulty smoke detectors. Inspectors will ensure that the home meets safety standards, identifying any areas that require immediate attention. Addressing these hazards is crucial for the well-being of current and future occupants.

Addressing Safety Hazards

  • Smoke and Carbon Monoxide Detectors: Ensure these are present and functioning in all necessary areas.

  • Handrails and Guardrails: These should be secure and meet local building codes.

  • Trip Hazards: Uneven flooring or steps should be repaired to prevent accidents.

Appliance Failures

While not always a deal-breaker, faulty appliances can add unexpected costs for new homeowners. Inspectors will check the condition and functionality of major appliances, such as the stove, refrigerator, and water heater. Ensuring these are in working order can save time and money during the move-in process.

Evaluating Appliances

  • Age and Condition: Older appliances may be near the end of their lifespan and could require replacement.

  • Functionality: Ensure all appliances are in working order and free from defects.

  • Energy Efficiency: Consider the energy efficiency of appliances, as this can impact utility costs.

Exterior and Drainage Problems

The exterior of a home, including the siding, windows, and drainage system, plays a crucial role in protecting the property. Inspectors will look for signs of damage or wear, such as peeling paint, cracked siding, and poor drainage. Proper maintenance of these areas can prevent more significant issues down the line.

Exterior Maintenance Tips

  • Siding and Paint: Check for peeling paint or cracked siding, which can expose the home to the elements.

  • Window Seals: Ensure windows are properly sealed to prevent drafts and water intrusion.

  • Drainage Systems: Proper drainage is essential to prevent water from pooling around the foundation, which can lead to structural issues.
