"We thought we had foundation problems and contacted CNT for an estimate on repairs. ED VanOsdol came out at the specified
time to give us a quote. Ed generated a computerized lay out of the structure of the house and then crawed under the house and made pictures of the structure. He indentified one problem area which was minor and a potential problem area. He explained
what was happening to the foundation and because it was so minor, he told me how I could fix it myself. I told him that I would
pay for the inspection, but he said it was not necessary. If I ever do have problems with my foundation, I will certainly use them
for the repairs. I would recomend CNT to everyone. They are very professional and honest.

Structural Engineering questions, answered by experts

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.
