"John came out and looked at several issues, determined them to be cosmetic not structural and wrote a certified letter to that effect. We got great peace of mind from his visit."

"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."

"We hired Char to help us design an addition to our home in Burien, WA. Our addition adds a 300 sq. ft master suite to our 1100 sq. ft house. Char built our trust quickly. She listened carefully to our concerns, and used her own creativity to make huge improvements to our original plans. Our project wouldn’t have looked the same without her input. Char incorporated very specific requests from us concerning noise reduction, and went above and beyond to research many solutions for us to choose from. Char communicated her schedule clearly, we always knew exactly what she was working on, her deliverables, and what we would discuss in our next meeting. We never had a meeting that wasn’t useful. Char helped us navigate the Burien permit process, making sure the drawing package was complete enough to pass the first time. She reached out to specific city officials ahead of time to anticipate any issues before permit submittal. Char created very detailed drawings and has exceptional drafting skills. She added more detail than required at every stage of the design to help us make critical decisions earlier in the process. Our hired GC complimented Char’s drawing package when we put it out for bid, saying it was better than many that he’s seen. We also hired Char to meet with contractors and review estimates. She was able to help us navigate what was a reasonable price and weed out any weird or misleading estimates. In summary, Char has been a fantastic resource for us and has helped make our first major home improvement project much less daunting."

"Ward Engineering began working with Jared of Cornerstone Home Designs approximately 3 years ago to perform residential design work using Chief Architect design software. I find Jared to be the most capable Chief Architect designer I have ever worked with. Jared is very efficient and thorough at developing the residential Chief Architect models. In addition to being competent, Jared makes himself available to provide personal 1-on-1 training over the internet, which has been a huge blessing to our company and clients."

Structural Engineering questions, answered by experts

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.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

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.

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.
