"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."

"Linda was excellent! Knowledgeable, great communicator and honest. We were told structural work was needed on our 100+ year home but after a thorough assessment, Linda recommended tuckpointing only!"

"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."

This was a big important project for our home and I am extremely happy with how it came out! The cost was very reasonable and there were no surprises, everything was open and honest. I would definitely use them again and recommend to friends and family. Thank you AP!"

"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. She assisted in guiding me in obtaining required site plan for the residence; addressed the structural, electrical and plumbing details required; drafted and created the architectural floor plans that fit my vison of interior space; and facilitated in obtaining the necessary city permits from City of Chicago. 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 National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

Provides expert analysis, ensuring safety and compliance with building codes.

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.

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.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.
