"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."

"I had the pleasure of working with Bryson on a recent project, and I couldn’t be more impressed with their work. From start to finish, Bryson demonstrated extensive knowledge and expertise in structural engineering. They took the time to understand the project’s unique needs and provided clear, practical solutions that ensured everything was both safe and efficient. One of the standout qualities was their excellent communication. They kept me informed at every stage, answering questions promptly and offering advice when needed. Even when challenges arose, Bryson approached them with professionalism and a problem-solving mindset, ensuring that the project stayed on track. The quality of the work was exceptional. Every detail was carefully considered, and I felt confident in the structural integrity of the design. Bryson truly went above and beyond, offering both technical skill and a genuine commitment to the project’s success. Thank you and I look forward to working with you again."

"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."

"Before buying I needed a specialist to look deeper into a potential issue, Greg was very knowledgable, friends and as it turns out just the guy for the job. He exposed all the issues and made my choice of not buying a house an easy one. Great to work with, has pest and structural qualification and was very reasonable. I'd highly recommend him and will be calling him again soon when I find another house."

FAQs for engineer structural projects in Seattle, WA

To determine if a wall is load-bearing, start by checking your home’s original plans or asking a structural engineer. Exterior walls always carry weight, but interior ones only do if they sit over a beam or run perpendicular to floor joists. If a wall lines up with posts in the basement or falls directly under the roof ridge, assume it’s load-bearing and call a professional before attempting to remove it with a sledgehammer.

Calculating the wall load and sizing the beam must be performed by experts to ensure structural safety. You need a structural engineer to evaluate all load aspects and determine the proper beam dimensions. A professional engineer performs precise calculations and advises on any necessary enhancements, such as larger footings for support. An inspector then verifies that the revised structure meets all safety and code regulations before the finishing work begins.

Hiring a structural engineer is essential for ensuring your home remains structurally sound during any major renovation. Their responsibility is to deliver expert assessments and design recommendations for load-bearing modifications. The average cost to hire a structural engineer is $500, with rates ranging from $350 to $800. Consulting a licensed, experienced engineer guarantees that every structural project, whether constructing a new home or remodeling an existing one, is completed safely and efficiently.

Almost all load-bearing wall removals require a permit as they support everything above it, and building departments want proof that the new beam can handle the weight. Pulling a permit triggers plan review and inspections that confirm the work meets local code and safety standards. Skipping this step can lead to fines or being forced to rebuild later, so have your contractor pull the permit before work starts.

Removing a load-bearing wall to create an entrance for a carport or covered patio is a task that comes with defined cost implications. This modification requires extra structural adjustments to ensure safety and proper integration with the adjoining space. When you convert a wall into an entryway, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. The additional work required for this conversion reinforces the home’s integrity and ensures compliance with applicable building codes.
