Here are the top 10 red flags you should watch for in a home inspection:

Table of Contents

Foundation Cracks & Structural Issues

Foundation issues are one of the most serious problems a home can have.

Look for horizontal cracks in foundation walls, stair-step cracks in brickwork, and doors or windows that stick. These can indicate settling or structural movement, which can cost tens of thousands of dollars to repair.

Most Home Inspectors are qualified to acknowledge signs of issues, but may not be versed in remedies, severity, or cost. If foundation issues are flagged, consult a structural engineer for a second opinion.

Roof Damage & Deterioration

A roof protects everything inside the home, so its condition is critical

Signs of trouble include missing or curled shingles, sagging roof lines, and water stains in the attic. Asphalt shingles typically last 15-30 years, so check the roof’s age. 

A failing roof could mean leaks, mold, and costly repairs.

Plumbing Problems

Old plumbing, particularly galvanized steel pipes, can corrode and restrict water flow. 

Look for leaks under sinks, signs of water damage around toilets and tubs, and listen for noisy pipes. Water pressure tests and pipe inspections can reveal hidden problems.

Leaking or outdated plumbing can lead to major water damage and high repair bills.

Electrical System Issues

Outdated wiring, such as knob-and-tube or aluminum wiring, can pose fire risks.

Ensure that the panel and breakers are updated to handle modern electrical loads. Look for flickering lights, warm outlets, or frequent circuit breaker trips as warning signs.

Unsafe electrical systems are among the leading causes of house fires.

Water Damage & Mold

Any signs of past water intrusion are cause for concern.

Water stains, mold spots, and musty odors could point to leaks that have gone unchecked. Mold is not only costly to remediate but can cause health issues like asthma and allergies.

A home inspector may recommend a mold specialist if extensive growth is found.

HVAC System Problems

Heating, ventilation, and air conditioning systems are expensive to replace.

During the inspection, the inspector will check if the system is running efficiently and whether it has been maintained. Average life expectancy for mechanics is typically 12-15 years.

Dirty filters, strange noises, or inconsistent temperatures are signs that the system may need repair or replacement.

Poor Drainage and Grading

Proper grading is essential to direct water away from the home’s foundation.

Pooling water can lead to basement leaks, foundation cracks, and mold growth. Your inspector should look at the grading, downspouts, and whether water appears to be draining correctly. Improper drainage is often a hidden threat that causes big problems later.

Pest Infestation

Signs of termites, carpenter ants, or rodents include droppings, damaged wood, and hollow-sounding walls. Pests can cause thousands of dollars in structural damage if left unchecked.

Small, dark pellets in kitchen cabinets, under sinks, in basements, or attics can signal rodents or insects like cockroaches. A persistent musty or ammonia-like odor could be caused by rodent urine, or decaying organic material from a pest nest.

Windows & Door Trouble

If windows and doors stick or won’t close, it could be a simple maintenance issue…or a sign of foundation movement. Drafty windows also hurt energy efficiency, leading to higher utility bills. 

Make sure all windows and doors are inspected for proper operation and sealing.

Asbestos, Lead Paint, or Other Environmental Hazards

Homes built before the 1980s often contain hazardous materials like asbestos and lead paint.

Disturbing these materials can release dangerous fibers and particles into the air. Testing and remediation by certified professionals may be necessary.
