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!"

"The entire crew including Brian Weinstock, the owner, was very hands on and extremely helpful throughout the whole process in every way. The crews treated our home as if it was their own and cleaned up very well each day. Brian was very honest, he stuck to the proposal and contract, Everything looks fantastic and it couldn't have gone more smoothly!!! We would highly recommend him to anyone."

"Painting was not completed as desired. Many incomplete areas with paint splashes and spills on floor (the latter was cleaned up by their cleaning crew when I complained). Painter was let go and several others were asked to complete the work but none did a great job and still many areas not completed. I stopped the process and will finish it myself.

Structural Engineering questions, answered by experts

A freestanding brick wall that's only one brick thick can usually stand six to eight feet high. If you need a higher wall, it should be at least two bricks thick for adequate stability, and it might require a footing to support the added weight. Additionally, some areas have regulations and codes dictating how high a brick wall can be, so check with local code enforcers to ensure your proposed wall complies with any regulations.

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.

If you intend to do the majority of the work yourself, you can pay to hire an architect or a structural engineer to ensure your home remains structurally sound. They can help with the planning to make sure everything is up to code and safe for your family. On the other hand, if you’re not sure your home will be completely safe when you’ve completed the project, let a pro do the job.

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.

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.
