What Happens During a Home Inspection

A home inspection is a thorough examination of a property's condition, usually conducted by a certified inspector before the sale closes. The inspector checks major systems and components, including:

• Foundation and structure

• Roof and gutters

• Plumbing and electrical systems

• Heating, ventilation, and air conditioning (HVAC)

• Interior walls, ceilings, floors, windows, and doors

• Appliances and safety features

  
  

The goal is to identify defects, safety hazards, and maintenance needs. The inspector provides a detailed report with photos and recommendations.

Foundation and Structural Problems

One of the most serious issues a home inspection can uncover involves the foundation and structural integrity. Problems here can lead to costly repairs and affect the home's safety.

Common Signs of Foundation Issues

• Cracks in basement walls or floors

• Doors and windows that stick or do not close properly

• Uneven or sloping floors

• Gaps between walls and ceilings or floors

  
  

Why It Matters

Foundation problems can cause water leaks, mold growth, and even structural collapse if left untreated. Repair costs vary widely depending on the severity but can reach tens of thousands of dollars.

What to Do

If an inspection reveals foundation concerns, get a specialist’s opinion. Minor cracks might only need sealing, but major shifts could require underpinning or rebuilding parts of the foundation.

Roof and Gutter Concerns

The roof protects the entire home from weather damage. Inspectors look for signs of wear and damage that could lead to leaks.

Common Roof Issues

• Missing or damaged shingles

• Curling or buckling shingles

• Signs of water damage or stains on ceilings

• Improperly installed or clogged gutters

  
  

Why It Matters

A damaged roof can cause water to enter the home, damaging walls, insulation, and electrical systems. Gutters that do not drain properly can lead to foundation erosion.

What to Do

Regular roof maintenance extends its life. If the roof is near the end of its lifespan or shows significant damage, plan for replacement. Clean gutters and ensure downspouts direct water away from the foundation.

Plumbing System Defects

Plumbing issues can range from minor leaks to major pipe failures.

Common Plumbing Problems

• Leaking faucets or pipes

• Corroded or outdated piping materials (like galvanized steel)

• Low water pressure

• Water heater problems

  
  

Why It Matters

Leaks waste water and can cause mold and water damage. Old pipes may burst or contaminate water. Water heaters that don’t function properly can increase energy bills and reduce comfort.

What to Do

Fix leaks promptly to avoid damage. Consider upgrading old pipes to modern materials like copper or PEX. Test water pressure and replace faulty water heaters if needed.

Electrical System Issues

Electrical safety is critical. Inspectors check wiring, outlets, panels, and grounding.

Common Electrical Concerns

• Outdated knob-and-tube or aluminum wiring

• Insufficient number of outlets

• Missing or damaged circuit breakers

• Lack of ground-fault circuit interrupters (GFCIs) in wet areas

  
  

Why It Matters

Old or faulty wiring increases fire risk. Insufficient outlets can lead to unsafe use of extension cords. GFCIs protect against electrical shocks in kitchens, bathrooms, and outdoors.

What to Do

Hire a licensed electrician to evaluate and update wiring. Install GFCIs where required by code. Add outlets to reduce reliance on extension cords.

HVAC System Problems

Heating and cooling systems affect comfort and energy costs.

Common HVAC Issues

• Dirty or clogged filters

• Inconsistent heating or cooling

• Strange noises or smells

• Lack of maintenance records

  
  

Why It Matters

Poor HVAC performance can increase utility bills and reduce indoor air quality. Neglected systems may fail prematurely.

What to Do

Change filters regularly and schedule annual professional maintenance. Repair or replace malfunctioning units to ensure efficient operation.

Interior and Safety Concerns

Inspectors also check for issues inside the home that affect livability and safety.

Common Interior Problems

• Water stains or mold on walls and ceilings

• Cracked or uneven flooring

• Doors and windows that don’t seal properly

• Missing smoke detectors or carbon monoxide alarms

  
  

Why It Matters

Water damage can lead to mold, which affects health. Poorly sealed doors and windows increase energy costs. Smoke and carbon monoxide detectors save lives.

What to Do

Address water leaks and mold immediately. Repair or replace damaged flooring. Install and test smoke and carbon monoxide detectors regularly.

How to Use Your Home Inspection Report

After the inspection, you will receive a report detailing all findings. Use this report to:

• Negotiate repairs or price reductions with the seller

• Plan future maintenance and upgrades

• Decide whether to proceed with the purchase

  
  

Not every issue requires immediate action. Prioritize safety hazards and major repairs first.

Final Thoughts

Understanding common home inspection issues helps buyers protect their investment. Pay close attention to foundation, roof, plumbing, electrical, HVAC, and safety concerns. Use the inspection report as a tool to make smart decisions and maintain your home’s value over time.

Taking the time to learn about these issues now can save you money and stress later. If you are buying a home, always schedule a professional inspection and review the findings carefully. Your future self will thank you.

If you are preparing to buy a home, start by researching qualified home inspectors in your area. Ask for references and check reviews to find someone thorough and trustworthy. A good inspection is the first step toward a safe and comfortable home.
