J Welch Engineering is a single person firm with ten years of experience in Structural design.

"Josh came out for an hour to talk through how moving the staircase might go. He was polite, professional, prompt. I paid him for an hour of his time ($125). I ended up using a different structural engineer because Josh was booked 13 weeks out and I wanted to get my permit more quickly than that. His overall quote for the work was around $1000, which seemed very reasonable to me. He was patient when answer all of my MANY questions. He was very understanding and polite when I told him I would be using a different engineer."

We specialize in new additions, interior or exterior home renovations, including bathroom and kitchen remodeling, home additions,roofs, granites, garages and more!

"I cannot express enough how unsatisfied I am with the ER Eliete Remodeling Services, LLC and the services provided by the general contractor I hired for my home renovation project. From start to finish, the experience was nothing short of a nightmare. I regret choosing them and would strongly advise others against making the same mistake. Poor Quality Workmanship: The quality of their work was abysmal. The finishes were sloppy, and it was evident that they lacked attention to detail. I had to point out numerous mistakes and flaws that should have been caught during the construction process. Unprofessional Behavior: The behavior of the contractor and their crew was unprofessional and disrespectful. They yelled at my wife, and constantly said we are to picky Lack of Expertise: It became apparent that the contractor lacked the necessary expertise to handle certain aspects of the project. They made numerous mistakes that had to be fixed, causing even more delays and frustration. Had to pay others to fix their mistakes. In conclusion, my experience with this general contractor was a complete disaster. Their lack of professionalism, communication, and expertise resulted in a poorly executed project that was overpriced and far from meeting my expectations. I strongly advise anyone considering hiring this contractor to think twice and explore other options. Save yourself the headache and disappointment. Two weeks after he left our home, we had a major plumbing leak, that required walls to be opened up, more money spent to correct his problems. ER Elite Remodeling will take your money, and either do a poor job or walk away with project not finished, not take your phone calls or texts, but gladly keep your money. Found out later that license is expired...................."

FAQs for structural engineering projects in South Prairie, WA

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

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.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
