"We recently completed a project with Lallygone to remove 3 columns from my basement. The entire experience from scheduling a consultation with the engineer to completion of the job was seamless. The team is knowledgeable, courteous and very professional. I strongly recommend them for replacing lally columns or any structural improvements in existing or new homes. George thanks for your honest recommendations, Chris for your in-depth inspection and detailed explanation & Lena for managing it end to end.. thanks for the wonderful experience."

"Mr Mikaeel immediately contacted me once I put in a request on Home Advisor. He explained his services and he offered me more options than I had received from other engineers. Those options included paying less money which I appreciated right away. He knew I didn't have much time to work with and we scheduled the next day. He arrived on time, was very personable, very professional, explained what I needed to know and also gave me great news. I will recommend him to anyone that needs a structural engineer Thank you Home Advisor!"

Customers say: Quality work

"We had a home inspection that recommended having a structural engineer inspect a defect. I called Robert on Monday, had the inspection on Thursday, and an official report on Monday. He understood our time crunch, and really helped us out. My fiancé enjoyed learning about our new home's foundation with Robert the day of inspection. The cost he quoted was the final cost with no hidden fees. He is personable and loves to share his vast knowledge of engineering. I highly recommend Robert and will use him again if we ever have any structural engineering needs."

"Joe designed a beautiful family room addition to expand our Cape Cod style home. His design integrated the new room beautifully into the existing house and it looks like it was always there.  All of the builders who bid on his design remarked how detailed and complete his plans were. I would use him again without hesitation. A really good architect and a heck of a nice guy.

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"Julian delivered exceptional engineering analysis and design work for my residential gut rehab. He was consistently available, willing to help, and brought strong technical expertise to every discussion. His vision for an open‑wall layout led to the installation of a structural beam that completely transformed the home’s flow and created a true open‑concept space we never thought possible. He worked efficiently, communicated clearly, and carried himself with total professionalism. I highly recommend him to anyone looking to upgrade or reimagine their living space."

Structural Engineering FAQs, answered by experts

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.

Yes, they offer plans for repairs or reinforcements to address issues.

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.

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.

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.
