"In renovating our beach cottage in Warwick, RI we found the roof needed structural work. Building inspector required a structural engineered plan. Adam was easy to communicate with. He was timely with his plan and follow up inspection. He was also available by text and phone for questions during the project. He was great to work with!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"I was searching for an architect on Angie’s list we’re building a new house in Newington, Ct Roger Greenwald popped up in my search. Roger called me the next day and we booked an appointment for him to come out to the property. He asked us what we wanted and designed the house for exactly what we needed. My mother is an elderly woman, Roger very patient and answered all my mother‘s questions. He wanted to design the house to what stage we were in our life and what would work for us. Roger is extremely knowledgeable in what he does, he returned every phone call every email immediately or within 24 hours. The house he designed was just absolutely beautiful it was everything we wanted. The blueprints were ready within two weeks if not sooner. Roger Greenwald Architect is FIVE STAR I highly recommend him. Once my house is fully built I will come back and upload photos"

Structural Engineering FAQs, answered by experts

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

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.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

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