We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. We provide professional structural inspection, design, drawing, permit support, and consulting.

"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."

Structural Engineering questions, answered by experts

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

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.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.
