Can you put a doorway in a structural wall?

• <div><p>Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.</p></div>

• <div><p>Provides expert analysis, ensuring safety and compliance with building codes.</p></div>

Q: Is a structural engineer’s report worth it?

• <div><p>A structural engineer&rsquo;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&rsquo;t have to pay thousands of dollars for structural repairs right after closing on a property. </p></div>

Q: Are beams and joists the same?

• <div><p>No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.</p></div>

Q: Why are studs 16 inches apart?

• <div><p>In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called &quot;on-center&quot; and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called &quot;advanced framing&quot;. This requires careful planning and adherence to local building codes to ensure structural integrity. </p></div>

"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!!
