"Two years ago my wife and I noticed that our foundation was beginning to settle.  We had huge cracks in the dry-wall and our front door wasn't opening and closing properly. We decided to contact Advanced Foundation Repair and Replacement, owner Frank Matyiko.  He got a structural engineer to our house.  The engineer recommended that we needed twelve piers in order to fix our foundation.  the entire construction project went as planned.  Advance Foundation provided us with a transferable warranty in case we decided to sell our home. 
The overall experience was wonderful their crew was very professional and we would use them again and recommend them to anyone!!

"I cannot speak for the company as a whole (they are headquartered in St Louis), and I have yet to receive their official report (which is to come from their home office). But the engineer himself clearly knew his subject matter, was highly observant and even addressed my drainage issues (water management being his specialty), a tangential topic. I liked the man very much."

Structural Engineering questions, answered by experts

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.
