We got our start in residential and proudly continue to support these clients. Let us be your team for structural support. Give us a call to discuss any questions or concerns you might have.

Home Renovation
When it comes to home renovations, it takes much more than a sledge hammer and tips from your favorite DIY show to get started. Whether you are a homeowner, contractor or architect, make sure your renovation is done right with professional input from Stein Lasseigne.  Our experienced staff can help you with adding a second story to your house or sizing a beam for removal of a wall and everything in between.

New Construction
Building your dream home can be an exciting but overwhelming experience.  We recommend engaging an architect at the initial planning phase because “picking out a house plan” may be misstep at the very start of your journey.  In addition to the multiple valuable services your architect provides, you may also need structural consulting in the form of framing, wind resistance and foundation designs, which are critical to the proper construction of your home. Our professional staff can evaluate your plans and provide the structural engineering needed to prevent your dream home from becoming a nightmare.

If you’re an architect working with residential clients, we would be excited to provide structural consultation at any phase of your residential projects.

Contact us with your ideas and scope of your next residential project.


At Stein Lasseigne, we offer comprehensive structural engineering services to a variety of industrial clients, including refineries, chemical and petrochemical plants, and various other manufacturing facilities. We offer support on projects ranging from conceptual design to detailed engineering of new industrial structures as well as assessments of existing structures.

Whether it’s a new facility or a modification to an existing structure, we have the expertise to provide the solutions you need.

Contact us today to discuss what specific services we can provide for your industrial project.
