"This project went very smoothly and we were extremely impressed with Ryan and his crews. He was always great at communicating with us about the schedule and answering all our questions. I was greatly impressed with his attention to detail and the level of quality with everything from the tile installation to the lighting and electrical work. I would highly recommend Johnson Custom Building for their remodel/home upgrade needs. We definitely plan on using their services again for our next remodeling project."

"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."

"Evolution design worked with me on designing and addition for a 100 and 5 year old house. We worked on the dimensions of the addition Plus the materials. Evolution understood the local zoning which was amazing that they knew that. We have not started construction. And evolution can help pull the permits and I'm considering them for that as well. All in all it was a long project but it was done efficiently, working with several of the staff an the departments."

Structural Engineering questions, answered by experts

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

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

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.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
