"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."

Customers say: Super punctual

"Angelo and his crew were WONDERFUL. Every promise that AP Builder / Angelo made was met and exceeded.
1. Angelo gave me a anticipated completion date for the construction job: he finished before the completion date.  I even allocated additional time in the contract in order for his company to finish the job, but he didn't need it. He kept to his schedule and his promise.
2. Angelo gave me a cost estimate: he kept his promise on cost exactly. The only additional amounts of money spent were because I modified and changed a couple of construction points.
3. Angelo assured me that I would be happy with the workmanship: his promises were exceeded. The law office building addition turned out wonderful.
4. Communication with Angelo during construction: Angelo and his office was exceedingly responsive to my questions and requests. I always knew that when I called that I would either speak with him directly, receive a punctual call back from him, and he would agree to meet me at the construction site at an agreed time.
5. Angelo exceeded all of my expectations at a very reasonable cost. His company provides top quality work for a bargain price.  As a side note, Angelo caught and fixed a structural problem before it happened. The architect had under-estimated the strength needed for a main load beam, Angelo pointed out the flaw, and we fixed the problem before it was built into the structure.  He saved me from a HUGE problem down the road (when the roof would have buckled and bent).  Angelo's decades of experience cannot be understated.
I read another review of AP Builder wherein the author suggested that this company was a bit expensive. I strongly disagree. I would suggest instead that some people may have unrealistic expectations and want to cut corners and prices when instead they should be investing in quality work. 
If Angelo will accept your job, you should seriously consider using this guy.

Structural Engineering questions, answered by experts

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.
