"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"I couldn't find a structural engineer to look at my drawings and provide good engineering services until I called Peter. He was willing to look at the project even though there were still questions about the build to be answered."

"I was referred to 800 Remodeling by Angie's List, and the owner, Amir, called me literally minutes after I received the referral. I described my situation to him and we scheduled a meeting at my home for the following day. He arrived promptly and immediately introduced himself with a picture ID and his state contractor's license. After inspecting the cracks that were of concern to me in a structural post supporting a major beam, he took some pictures and promised to get back to me with some recommendations. The next day, he called just as he had promised, told me that after talking with a structural specialist he did not believe the post needed to be replaced, but nevertheless gave me a rough-order-of-magnitude estimate on what a replacement would cost, should I decide to have that done. After some additional research, I concluded that the cracks are typical and not impairing the structural integrity of the post, and decided for added insurance simply to reinforce the post with some wrap-around steel bands. Since that is a small and simple job, Amir offered to refer me to someone else to do that job for me. He did not charge me for the consultation or the time he spent in discussions with other specialists. So although I ultimately didn't hire him for this job, I was impressed by his professionalism and shall definitely be contacting him again for some larger jobs I am planning in the future."

"-It was about 2 weeks ago that I met Mr Sal and he cam to see the project site as well to take the measurements required next day later he immediately scheduled an appointment with my local city of Westminster to find out what was exactly requested soon after he left it took only 3 days for him to develop all the structural calculations for the mother-in low quarter and the 2 car garage I was extremely pleased for his professionalism and fast expedited work. The quotes that I was provided from him were by far quite fair than the other I had interviewed prior of meeting him. Mr Sal truthfully went the extra mile to make it happen for what I was looking for. I therefore would Highly recommend to anyone in need of such works to look for Mr. Sal from AAA Engineering Design, you will never be disappointed. I want everyone to know that he is truly a great asset to our community. Thank you John Trimarco"

Structural Engineering FAQs, answered by experts

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

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.

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

Costs depend on material choices, labor, and the extent of structural modifications.
