Call us first.

Always call an independent inspector first. A foundation repair company sending someone to evaluate your foundation is sending a salesperson — not a licensed evaluator. Their business model depends on finding something to repair. An independent licensed inspector has no financial relationship with any repair company, no repair services to sell, and no incentive to recommend work that isn't needed. Call Imperial Pro first. If repair is genuinely warranted, we'll tell you exactly what it is and what it should cost — so you can compare bids objectively.

The primary driver is Houston's expansive clay soil combined with the seasonal wet-dry cycle. Oak tree roots are the number one cause of adverse foundation movement in Greater Houston — and it is not close. Roots extract moisture from clay soil beneath and around foundations, causing differential shrinkage and settlement. Secondary causes include poor drainage routing water toward the foundation, plumbing leaks beneath the slab, and insufficient post-construction soil moisture maintenance. Most of these causes are addressable without $20,000 in piers.

A foundation elevation survey uses a ZIPLEVEL precision altimeter to measure the actual height of your foundation at multiple points across the entire slab. This gives you a documented, measured baseline of how the foundation is performing — not just a visual observation. In Fort Bend County's expansive clay soils, having that baseline is essential for tracking movement over time, quantifying whether movement has occurred between readings, and protecting yourself from repair proposals that aren't supported by data.

Yes. Fort Bend County's expansive clay soils make foundation evaluation essential homebuyer due diligence — not optional. A standard home inspection includes a visual assessment of the foundation, but a standalone foundation elevation survey adds precision measurement that reveals differential movement patterns not visible to the eye. For any home with large trees nearby, near drainage channels, or showing any cosmetic distress, a dedicated foundation evaluation is strongly recommended alongside the standard home inspection.

A Level A foundation inspection includes visual assessment plus ZIPLEVEL spot elevation samples at key locations and a verbal performance opinion. It is the appropriate starting point for most residential evaluations. A Level B adds a complete precision elevation survey across the entire foundation footprint, deflection and tilt analysis, and a professional written report with photos — recommended for due diligence, properties with known movement history, or any situation where written documentation is needed for lenders, negotiations, or legal purposes.

Yes — and the stakes are considerably higher than residential. Foundation repair on a commercial building can range from tens of thousands to hundreds of thousands of dollars. For buyers, a pre-purchase inspection quantifies exposure before any contractual obligation. For tenants, a pre-lease evaluation documents existing conditions. For property managers, periodic elevation surveys create a documented performance record for asset management, insurance, and future transaction due diligence. Commercial evaluations are custom-scoped — contact us to discuss your property.

Physical root barriers are high-density polyethylene (HDPE) panels installed vertically in a trench between a tree and a structure. They intercept root growth and redirect it downward and away from the foundation zone, preventing the moisture extraction from clay soil that causes differential settlement. Minimum installation depth is 30 to 36 inches. Root barriers do not harm trees — they redirect growth without severing root systems. For commercial properties, HOAs, and builders, documented root barrier installation also creates a record of proactive asset protection relevant to warranty claims and insurance.
