Get matched with top structural engineers in Cortland, IL

"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."

"Quality windows were installed in my garage. Contractor matched the exterior painting perfectly. He fixed the bannister and wood planks on my deck using like kind and quality materials. He also secured a soffit where wasps had entry to my attic. He tiled areas in my lower level that required new tile after a drain tile contractor did their work. In addition to tile work that needed to be done he replaced the base boards. His work was professional and he went to all lengths to perform quality work with quality product. This work was done over the course of a few months, approximately, March through July 2019"

"Chris came on board to complete the build of our new home part way through the build process. There were a lot of issues going on that pertained to the project manager that were quickly corrected as soon as Chris came on board. He is on top of everything and quickly remedies issues that arise. He was an absolute joy to work with and was able to get our house back on track to completion. I wouldn’t trust anyone else to do the work! Any new projects I have in the future would be through him! Thank you for making our dream house come true!"

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

"They did a good job, reasonable price. His actual work is good and I will recommend them again. If there is one thing I will not not like is that he left a stain in my bathroom."
