Quick, low-risk steps
- Record changes by date instead of deciding from one crack.
- Photograph from the same safe position with a reference scale.
- Note sticking doors, uneven floors, leaks, and recent weather.
- Separate an independent engineering opinion from a repair bid.
- Compare quantities, engineering, restoration, and warranty terms.
What a Contractor Inspection Typically Includes
A foundation repair contractor usually offers a free inspection. The inspector looks for visible signs like cracks, uneven floors, and sticking doors. They measure relative elevations and may use a level to check for slopes. The goal is to propose a repair plan and provide a quote for the work they can perform.
This inspection is not a structural engineering evaluation. The contractor's representative is often a salesperson trained to identify problems that their company can fix. Their report will focus on the repair system they sell, such as steel piers or concrete pilings, and may not address underlying causes like soil movement or drainage issues.
- Free or low-cost visual assessment.
- Focuses on symptoms correctable by their repair method.
- Provides a repair quote, not a root-cause diagnosis.
- May not include a plumbing leak test or soil analysis.
- Often includes a sales presentation for their services.
What an Independent Structural Engineering Evaluation Provides
A Texas-licensed structural engineer performs an unbiased evaluation. They assess the foundation's condition, identify causes of movement, and recommend necessary repairs—if any. The engineer does not sell repairs, so their advice is impartial. They may use tools like a manometer for elevation surveys and review soil data from the USDA Web Soil Survey.
The engineer's report can be used to obtain comparable bids from multiple contractors. It specifies repair quantities, installation depths, and performance criteria. This helps you avoid unnecessary work and ensures that any repairs meet a professional standard. An engineering evaluation is especially valuable before buying or selling a home, or when you suspect significant structural issues.
- Unbiased diagnosis by a licensed professional.
- Identifies root causes, such as expansive soils or drainage problems.
- Provides a detailed scope of work for contractors to bid on.
- Helps prevent unnecessary or inadequate repairs.
- Useful for real estate transactions and insurance claims.
Key Differences and When to Choose Each
A contractor inspection is a good first step if you notice minor cosmetic cracks and want a quick opinion. However, if you see signs of ongoing movement, such as widening cracks or doors that suddenly stick, an engineering evaluation is safer. The engineer can determine if the movement is active and whether it threatens the structure.
For complex situations—like a home with previous repairs, a pier-and-beam foundation, or a property on highly expansive soil—an engineer's expertise is crucial. They can also help if you disagree with a contractor's proposal or need documentation for a warranty claim. Remember, the USGS notes that only a qualified on-site professional can evaluate a specific building's structural integrity.
- Choose a contractor inspection for minor, stable cracks and a quick estimate.
- Choose an engineering evaluation for active movement, structural concerns, or real estate transactions.
- An engineer's report allows you to compare bids on an equal basis.
- Contractor inspections may be biased toward their own repair system.
- Always check the professional's license with the Texas Board of Professional Engineers and Land Surveyors.
Questions to Ask Before You Commit
Before scheduling any inspection, ask about the provider's qualifications and what the evaluation will include. For a contractor, inquire about their experience with your foundation type and whether they perform a plumbing leak test. For an engineer, confirm they are licensed in Texas and have experience with residential foundations in the DFW area.
Request a sample report to understand the level of detail you will receive. Ask if the evaluation will include elevation measurements, a review of soil conditions, and specific repair recommendations. A thorough evaluation should address the items in our scope checklist, such as permit requirements, warranty terms, and restoration needs.
- Are you a licensed professional engineer or a contractor salesperson?
- Will the evaluation include a floor elevation survey?
- Do you review soil data from the USDA Web Soil Survey?
- Will the report specify repair quantities and installation depths?
- Can I use this report to get bids from multiple contractors?

Common questions
What homeowners ask next
Is a contractor inspection enough to diagnose my foundation problem?
A contractor inspection can identify visible symptoms and suggest repairs, but it may not determine the underlying cause. For an unbiased diagnosis, consider an independent structural engineering evaluation.
How much does a structural engineering evaluation cost in DFW?
Costs vary based on the property size and complexity. Contact several licensed engineers for quotes. An evaluation can save money by preventing unnecessary repairs.
Can I use the USDA Web Soil Survey to check my soil risk?
The USDA Web Soil Survey provides general soil data for your area, but it is not a substitute for a site-specific evaluation by a qualified professional. Soil conditions can vary within a single property.
