Customers say: Super punctual

"Great Lakes Builders were amazing. They were fantastic problem solvers and partners, collaborating every step of the way with our structural engineer and us. It was apparent that completing quality work within the timeframe and estimate really mattered to them. We were even out of town for part of our project, and they zoomed with us daily to show us exactly what was being done. They were helpful in connecting us to outside contractors (dry wall, electrician, etc) so that by the time the project was completed, it was REALLY completed. They were meticulous, methodical, helpful AND friendly."

"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."

"I had purchase the $1399 Deal to have paver stone patio installed in the back yard. Working with Maria, I decided to expand from 10x20 space to cover the entire width of my garage.  The additional price quoted was fair.  Because I purchased the service in October 2013, the weather was changing and the window of opportunity to install was small. Nevertheless, Maria and her crew were able to install the patio within 3 days (1 day had rain). 
The crew arrived promptly,  were courteous and were professional.  Maria remained on site supervising the work. I am please with the patio and plan to use the company for future landscaping project.

"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

If your home's foundation was damaged due to shifting soil, the same problem will reoccur unless you stabilize the structure by adding posts in the bedrock.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
