A professional home inspection is one of the most important steps in understanding the true condition of a property. Whether you’re buying, selling, or maintaining a home, inspections reveal hidden issues that may affect safety, structural integrity, and long‑term costs. Interior Home Inspections, a full‑service inspection company with more than two decades of experience in the Okanagan and Shuswap regions, has identified the most frequent problems that appear during residential inspections. This guide explores these common issues, why they matter, and how homeowners can address them proactively.
Structural and Exterior Issues Commonly Identified
Structural and exterior components form the foundation of a safe and durable home. During inspections, these areas often reveal problems that may not be visible to the untrained eye. With over 40 years of construction experience, Interior Home Inspections uses industry‑standard practices and infrared thermal imaging to detect issues early and accurately. Understanding these common findings helps homeowners plan repairs and prevent further damage.
Foundation Cracks and Settlement Concerns
Foundation issues are among the most significant problems uncovered during home inspections. Small cracks are common and often harmless, but larger cracks or signs of shifting may indicate structural movement. Inspectors look for uneven floors, sticking doors, and visible gaps that suggest settlement. Left unaddressed, foundation problems can worsen over time and lead to costly repairs. Early detection allows homeowners to consult structural professionals and take corrective action before damage spreads.
Roofing Wear, Damage, and Aging Materials
Roofing problems frequently appear in inspection reports. Missing shingles, deteriorated flashing, and worn roofing materials can lead to leaks and moisture intrusion. Inspectors also check for sagging rooflines, poor ventilation, and signs of previous repairs. Because roofs protect the entire home from weather exposure, even minor issues can escalate quickly. Regular maintenance and timely replacement of aging materials help preserve the home’s structural integrity and prevent water damage.
Exterior Drainage and Grading Problems
Improper drainage is a common issue that can cause significant long‑term damage. Poor grading around the home allows water to pool near the foundation, increasing the risk of leaks and structural deterioration. Inspectors evaluate downspouts, gutters, and soil slope to ensure water is directed away from the home. Correcting drainage issues often involves simple solutions such as extending downspouts or adjusting landscaping, making it an easy but essential fix for homeowners.
Interior System Issues Frequently Found in Inspections
Beyond the exterior, interior systems such as electrical, plumbing, and HVAC play a crucial role in home safety and comfort. Interior Home Inspections follows the Home Inspectors Association BC Scope of Inspection to ensure all major systems are evaluated thoroughly. Many of the issues found in these systems stem from aging components, improper installations, or lack of maintenance.
Electrical System Deficiencies
Electrical issues are among the most common—and potentially dangerous—problems found during inspections. Outdated wiring, overloaded circuits, and improperly installed electrical components pose fire hazards and safety risks. Inspectors often find missing junction box covers, double‑tapped breakers, and insufficient grounding. Homeowners should address electrical deficiencies promptly by hiring licensed electricians to ensure compliance with safety standards and reduce the risk of electrical failures.
Plumbing Leaks and Aging Pipes
Plumbing systems frequently show signs of wear, especially in older homes. Inspectors look for leaks under sinks, corrosion on pipes, and water stains that indicate hidden moisture problems. Aging materials such as galvanized steel pipes may restrict water flow or fail unexpectedly. Plumbing issues can lead to mold growth, water damage, and costly repairs if not addressed. Regular maintenance and timely replacement of outdated components help ensure a reliable plumbing system.
HVAC Performance and Ventilation Concerns
Heating, ventilation, and air conditioning systems require regular upkeep to function efficiently. Common inspection findings include dirty filters, inadequate airflow, and aging furnaces or air conditioners. Poor ventilation can also lead to moisture buildup and indoor air quality issues. Inspectors evaluate system performance, visible ductwork, and maintenance history to identify potential problems. Homeowners can extend the lifespan of their HVAC systems by scheduling routine servicing and replacing filters regularly.
Moisture, Insulation, and Safety Issues
Moisture intrusion, insulation deficiencies, and safety hazards are frequently identified during home inspections. These issues can affect energy efficiency, indoor comfort, and overall home safety. Interior Home Inspections uses infrared thermal imaging to detect hidden moisture and insulation gaps, providing homeowners with a clearer understanding of their home’s condition.
Moisture Intrusion and Mold Risks
Moisture problems are among the most common and concerning issues found in homes. Leaks around windows, roofs, and plumbing fixtures can lead to mold growth and structural deterioration. Inspectors look for visible signs of moisture, musty odors, and temperature variations that indicate hidden water intrusion. Addressing moisture issues promptly helps prevent health risks and costly repairs. Proper ventilation, sealing, and drainage improvements are key to maintaining a dry and healthy home.
Insulation Gaps and Energy Efficiency Problems
Insufficient insulation can lead to heat loss, higher energy bills, and inconsistent indoor temperatures. Inspectors often find missing insulation in attics, crawl spaces, and exterior walls. Thermal imaging helps identify cold spots and areas where insulation is lacking. Improving insulation not only enhances comfort but also increases energy efficiency. Homeowners can benefit from upgrading insulation materials and sealing air leaks to create a more efficient living environment.
Safety Hazards and Code Violations
Safety hazards such as missing handrails, faulty smoke detectors, and improper installations frequently appear in inspection reports. These issues may seem minor but can pose significant risks to occupants. Inspectors also check for code violations related to electrical, structural, and mechanical systems. Addressing safety concerns ensures the home meets modern standards and provides a secure environment for residents. Simple fixes such as installing smoke detectors or securing loose railings can greatly improve home safety.
