"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 project went great. Peter is very professional, super knowledgeable, responsive and timely. The plans were done on time and there were no problems with the city review. They answered the questions the contractor had during the construction. Couldn't be happier with the whole process. I thought it would be more difficult than it was. Thanks to Peter and his team we feel very safe with the new addition. We are planning on putting a second story on our house (when we can afford it) and we will absolutely use Peter.

"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"If you?re here looking for an architect, look no further. Francisco is the man for the job. He helped us with a garage to ADU conversion. Francisco kept us informed and communicated with us throughout the entire project. He was very professional, helpful and patient. We had tons of questions and he had the answers. He is very efficient and great at his job. We would hire him again with no hesitation. Thank you Francisco for making for making this process a breeze!"

"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."

Structural Engineering questions, answered by experts

Most load-bearing walls are exterior, though they can also be interior.

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

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500.

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.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.
