"ESG Design was great to work with. I contacted them through Home Advisor for an impartial assessment of the cause of cracks in my ceiling, plus a few other issues. Eli, the engineer, did a thorough inspection and developed a solid plan for repairs. ESG also offered two levels of fees, which was extremely helpful for my budget. Thank you ESG for the service and peace of mind!"

"We have had the pleasure of working with **** since 2011, and over the years he has completed several projects for us that have spanned large complex remodels, new construction, and major structural repairs. The reason we have **** and Johnson Custom Builders as our sole resource for construction projects is due to his process for comprehensive planning and estimation, project management, attention to detail, project schedule integrity, excellent subcontractors, quality of outcome, his personal involvement in every detail-- and that he is incredibly pleasant to work with! We have dealt with many contractors and custom builders over the years, and **** and Johnson Custom Builders are the hands down the best."

"GS engineering, and Sim Singh in particular have been fantastic to work with. I am a general contractor and have had to hire a number of structural firms over time. Sim offers a very rare combination of a high level of skill in a highly technical field (specifically engineering) a high level of professionalism, and an overall pleasant personality/demeanor. As long as he has the time to take my calls, it is doubtful that I would ever call a different structural engineer than Sim."

"Mr. McCann came out to assess the water and carpenter ant damage to a wall and foundation sill plate of our home. He was able to quickly evaluate the problem area and provide the structural engineering report and repair task list we needed to get contractor bids on the reconstruction project. Highly recommended."

"The process working with Char to develop a set of design plans for my master suite addition has been fantastic. She has worked with me step by step, explaining the process at each point and what I can expect. She also listened to what I was looking for, drew up various designs, and then worked with me on modifications. She was a partner in the process the entire time, not only treating me with respect and professionalism, but talking through options and pros and cons with me so I ended up with the design I really wanted. Throughout the entire process I felt like I was in good and trustworthy hands. So much so that I will continue to use Char's assistance as I move forward on next steps with this project."

"Recently I had the opportunity to work with the guys from 3D Designs and Floorplans. My project was something very unusual, because I needed to build a clothes hanger rack in my new van for my mobile Dry Cleaning and alteration business. I draw myself some sketches and I explained what I want and they took over my project right away. Besides that I received the plan with all the measurements and details exact to a 1/16 in, Vasile , the drafter and 3D modeler created a full 3D image of the inside of the van with the rack mounted. When we decided with the welding company what material we are going to use and sizes, I sent Mr. Vasile all that and he adjusted everything for no extra charge. When the plan was done I received all the files with all the images and plans broken down to each section and precise sizes and measurements. One thing, the welding company thought was a joke and when I gave them the drafts and plans they just ignored the dimensions and rounded up some numbers so the frame of the rack came almost 1/2 in short. Guess what ? It did not match and fit where it supposed to be mounted, so they had to re do all over again to the exact sizes we had on the drafts. The welding technician and his supervisor said:" we never thought that 1/4 in can make such a difference" The experience I had with this company exceeded my expectations and the job was done 150%, top notch. Best affordable prices, no extra charges and great family like customer services. Now I rehired them again to work on my house plan and couple remodels we are planning to start soon, like ad two pergolas over front entrance and in the back over my deck, kitchen remodeling, and a plan for a new storage / working area shed. Amazing work, excellent prices and great ideas. I recommend this company to all my friends, and fellow veterans, since the company is managed by a veteran as well. Plus they do a great job on all VA plans to adjust your home to the disability needs."

"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."

Structural Engineering FAQs, answered by experts

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

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.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

Structural engineers can perform various inspections on different structures in your home. These inspections usually include a report detailing the engineer’s findings and recommendations for repairs so you can determine your next course of action for repairs, replacements, or new builds. Some of the most common structural engineering reports include:

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500
