"Great Lakes did a great job on structural work on my front porch. They recommended an engineer, and we were able to come up with a more-affordable plan that reinforced more of the porch. And they were able to do the work without losing the old wood trim, which initially seemed like it was going to have to come off. I really appreciated the attitude of all of the guys at Great Lakes: straightforward, honest, not trying to up-sell me. I'd definitely use them again for structural work."

"I would (and almost certainly will) work with AGGO again! We are buying a house and something came up where we needed a structural engineer to inspect something on very short notice. I reached out though Angi's to any company that might possibly employ structural engineers and Linda, a Structural Engineer with AGGO got back to me right away, first thing in the morning and was able to squeeze us in that very night. Linda was thoughtful and thorough. She careful looked over everything and even brought a large, bright light since it was after dark. She took her time, answered all of our questions, and gave us advice on other concerns and things to watch out for as well as reassuring us about things we didn't need to worry about in this situation. Even though she was probably working past her normal work hours to squeeze us in, nothing felt rushed or hasty."

"Marc did a great job on our garage expansion project! He was friendly and professional, taking all of our ideas and criteria and combining them into a great layout. The drawings themselves look great. We are still shopping the plans around to contractors, and Marc is always helpful with advice or ways to reduce cost. Would definitely recommend him to anyone looking for an architect."

"Architect Kristin Kollias has provided me with professional and responsive help in the renovation of a vacant single family bungalow in Chicago that required extensive repair for compliance with the City of Chicago codes.

Clearly she is a true professional and her services are greatly appreciated."

"We met with owner/senior architect, Firmin Senga to join us in the viewing of our desired property. We wanted to have an architect on board with us for reassurance that the updates we plan will work before we make an offer. He was very helpful."

"PMPC worked around my hectic schedule. I did not know of a HVAC licensed person. They recommended one to me. It worked out well. Any time I had questions or concern, I emailed or called, they always responded back the same or next day. I highly recommended PMPC to anyone. They are the real deal."

Structural Engineering questions, answered by experts

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They’ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.
