A solid foundation is essential for the safety and longevity of your home. But how do you know if your foundation is in good shape? Whether you’re buying a home, selling, or simply maintaining your property, a foundation inspection is one of the most important steps in identifying issues before they become costly problems.

In this complete guide, we’ll explain what a foundation inspection is, when you need one, what it costs, how it’s done, and what to expect next, especially for homes in the Houston area.

What Is a Foundation Inspection?

A foundation inspection is a professional evaluation of your home’s structural base. It’s designed to identify signs of movement, instability, or deterioration in the concrete slab, pier and beam structure, or crawl space system that supports your home.

Unlike general home inspections, foundation inspections are highly specialised and focus solely on assessing the strength, condition, and integrity of your foundation.

When Do You Need a Foundation Inspection?

Foundation inspections are recommended in the following situations:

• Buying or selling a home
  To uncover potential issues before closing.
  
• Noticing signs of damage
  Such as cracks, sloping floors, or sticky doors.
  
• After extreme weather
  Heavy rains or droughts can cause soil shifts in Houston’s expansive clay.
  
• Regular home maintenance
  Especially for older properties or homes with a history of settling.
  

Signs You May Have a Foundation Problem

Some signs are obvious. Others are more subtle. Here are the most common red flags:

• Cracks in walls, ceilings, or floors
  
• Sloping or uneven floors
  
• Doors and windows that stick or won’t close properly
  
• Gaps between walls and ceilings or floors
  
• Cracked brick or separation in exterior walls
  
• Standing water near the foundation
  
• Cracks around the chimney or porch steps
  

If you notice any of these symptoms, a foundation inspection should be your next step.

What Does a Foundation Inspector Look For?

During a professional inspection, the foundation specialist will assess both the interior and exterior of your property. Here’s what’s typically included:

Exterior Checks

• Cracks in the foundation walls or slab
  
• Gaps between the foundation and structure
  
• Drainage patterns around the property
  
• Tree roots and soil conditions
  

Interior Checks

• Floor level measurements using a zip level or laser level
  
• Drywall cracks, especially around doors and windows
  
• Functionality of doors and windows
  
• Movement or sagging in the floors
  

Under-Structure Checks (for pier & beam foundations)

• Inspection of crawl space
  
• Moisture levels and wood rot
  
• Condition of piers, beams, and floor joists
  

How Long Does a Foundation Inspection Take?

A thorough inspection typically takes 1–2 hours, depending on the size of your home and the foundation type. Pier and beam homes or properties with crawl spaces may take a bit longer due to the added complexity.

How Much Does a Foundation Inspection Cost in Houston?

The cost of a professional foundation inspection in Houston varies based on who performs it:

Type of Inspection	Cost Range
General home inspector	$150 – $300
Licensed structural engineer	$400 – $1,000+
Free contractor evaluation (like ours)	$0 (with detailed quote)

Foundation Inspection vs Structural Engineer Report

Foundation Inspection (Free or Low-Cost)

• Conducted by a foundation repair specialist
  
• Includes inspection and repair proposal
  
• Ideal for routine checks or suspected issues
  

Structural Engineer Report (Costly)

• Conducted by a licensed engineer
  
• Includes stamped report for legal/real estate needs
  
• Required for home sales, litigation, or insurance
  

What Happens After the Inspection?

If your home’s foundation is sound, no further action is needed, just peace of mind.

If issues are found, you’ll receive a tailored plan that may include:

• Foundation leveling using piers
  
• Slab lifting via foam injection or mudjacking
  
• Crawl space repair or beam replacement
  
• Drainage correction or root barrier installation
  

We’ll walk you through the entire repair process and help you prioritise repairs based on urgency and budget.

Can You Do a Foundation Inspection Yourself?

While homeowners can look for surface signs (like visible cracks or sticking doors), only a trained professional can accurately assess what’s happening beneath the surface. DIY inspections are helpful, but they are not a substitute for a proper evaluation.

How Often Should You Get a Foundation Inspection?

• New builds or no previous issues: Every 3–5 years
  
• Older homes (30+ years): Every 2 years
  
• After major weather events or signs of damage: Immediately
  

In a high-moisture, clay-rich environment like Houston, more frequent checks may be beneficial.

FAQs About Foundation Inspections
