"I had a fantastic experience working with this drafting firm. From the very first phone call, Kirsten?our drafting consultant? was clear, professional, and incredibly helpful. She explained the entire process in detail and made sure all of my questions were answered up front, which gave me immediate confidence in the team. This firm partnered with engineers and architects to get the best quote for me on a stamp for my plans after they did an exceptional job on drawing the prints that met all the requirements for permitting. Their coordination and attention to detail made the process very simple on my end. If you are looking for a highly capable drafting firm that knows how to get things done right, I highly recommend them!"

Structural Engineering questions, answered by experts

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.
