Customers say: Super punctual

"Martin and Jake are the absolute best to work with. They were thorough, efficient, professional and so easy to work with for our basement structural work. They took time to explain what needed to be done, coordinated with different contractors (plumbing, electrical), and were able to complete our project on time while we were out of town for just a week(!!). I can't recommend Great Lakes Builders more - they were a pleasure to work with and we will absolutely be using them again for any future work we need. 5+ stars!"

"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."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"Bill was able to come out within 4 days of my initial call. He was punctual and able to quickly identify the cracks as shrinkage and not any structural settling issues. He charges $400 for an inspection and $650 if you want a written report. We were fine with just a verbal since there were no problems. Pricey for 20minutes worth of work, but we're glad for the piece of mind. Everything went smooth."

"Seasonal Landscape Solutions deserves a higher rating than "Very Good"--a rating of EXCEPTIONAL and more. The new installation of brick steps, walkway, and front porch area of our house reflects outstanding workmanship and is absolutely beautiful, along with the repair work done on our brick backyard patio. In addition, our yard, flower beds, and "wild" areas now have a cleaner look (no more poison oak!). With unsurpassed customer service, asking questions and listening to what the customer wants, as well as offering suggestions, recommendations, and ideas for the project, I highly recommend them -- and will most definitely call them again!"

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.

Yes, they offer plans for repairs or reinforcements to address issues.

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.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

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.
