"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."

"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!"

Structural Engineering FAQs, answered by experts

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
