Why use an Independent Foundation Engineer for Plano Foundation Inspections?
With foundation issues being a common problem in Plano, there are plenty of foundation repair companies. Some of these companies offering advertise free foundation inspections. Many of these inspections, however, aren’t really free. These companies have an incentive to sell you piers. As an independent foundation inspector, our business at Lange Engineering is one thing: unbiased foundation inspections done by a licensed professional engineer. With a professional independent engineer, you get:
- An unbiased assessment of the foundation and drainage situation. Having an engineer can save you money in the long run and prevent additional harm to the foundation from unnecessary repairs.
- An Engineer’s report, required by most cities for permitting. (Most foundation repair contractors do not provide engineer reports).
- Accurate and detailed assessment of foundation damage
- An Engineer’s report greatly simplifies the contractor bid process by setting a precise scope of work. Contractors can provide a price estimate based of the engineer’s recommendations. This allows for a direct comparison between the contractors and creates a more competitive bid process

Eric Lange, PE
Mark Easter, P.E., is a licensed Professional Engineer with more than two decades of experience evaluating buildings, infrastructure, and environmental systems. He received a BS in Engineering from the University of Oklahoma, and a Master’s degree from Southern Illinois University. His work focuses on building diagnostics, structural performance, with particular experience in foundation behavior, moisture intrusion, and building-envelope issues common to Texas soils and climate.
Mark’s engineering background includes as an Air Force engineer, engineering design and his own private practice, In those roles, he evaluated structural systems, utilities, and site conditions; reviewed engineering designs and construction activities; and managed programs affecting long-term asset performance. He has also served in project and program manager positions and Air Force Base-wide programs and systems. This gives him strong grounding in risk assessment, data interpretation, and technically defensible decision-making.
In private practice, Mark specializes in structural evaluations of residential and light-commercial structures, with an emphasis on slab-on-grade and pier-and-beam foundations, differential movement, drainage impacts, and moisture-related issues, His approach is diagnostic rather than prescriptive: identify root causes, separate cosmetic issues from structural concerns, and clearly explain findings in plain language.
Clients value Mark’s ability to bridge the gap between engineering rigor and real-world practicality. His reports are thorough, unbiased, and written to stand up to scrutiny. He brings a systems-based perspective to every project, understanding how soils, structure, moisture, and construction practices interact over time.
