"I called five different companies from the Angi list before finding Colonna Consulting. When I called and I explained my situation to Nick (the owner), I immediately knew he was the one. Despite his tight schedule, he managed to fit me in on the same day. We hired Colonna and Nick to inspect our residential structural foundation. Nick responded promptly to my requests and explained everything clearly during the inspection. He completed the report within the same day. Working with him was a pleasure, and his professionalism made the process smooth and stress-free. Thank you very much Nick, for your fast response."

"They assessed project, did preliminary design, got helical pile subcontractor. We paid for soil and test drilling, and for topological survey as requested. The sub contractor hired to do scaffolding never did it, so we had to arrange that. So after 4 months of all the prep and 3 or 4 site visits by the engineer, we were ready to go. They never produced the design. After 2 months of emailing and calling we never got a single response. So we were out a couple grand engineering fee, and lost the entire build season. Had to start all over. (This was for a collapsing Livingroom on piers, so it was kind of urgent.) Trying to decide if it is worth going to small claims court to recover our feet. But the big problem is it just did not get done and the engineer just ghosted us, very unprofessional."

Structural Engineering questions, answered by experts

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

Most load-bearing walls are exterior, though they can also be interior.

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.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.
