"I have been very fortunate to work with Preston on 3 projects and found him to be very professional, thorough and complete tasks in a very timely manner. He works well with both clients, contractors and designers and developed a feel for the goals of the builds/design very quickly. All of our projects have been very different in design but Preston had no problem adapting to the design criteria of each. I would definitely recommend him."

Structural Engineering questions, answered by experts

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

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.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

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

The costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.
