"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

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

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.

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

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.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.
