"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."
"This review is long overdue. We can?t really express how happy we are with our new house that Char designed. We hired Char to design our remodel in 2013/2014. When I say remodel, that is a bit of an understatement, as we took a 700 square foot house to approximately 1,900 square feet, which included adding a basement. It is essentially a new home, and we couldn?t be more happy with it. We did the majority of the work ourselves, which is one reason it?s taken us this long to sit down and write a review. Although having a baby 1 month before the excavators came added a bit to the complexity of things... The project pushed us to our limits, and a little beyond at times, but it has all been worth it. Our 2 year old son absolutely loves to run around and scoot across our big long hardwood floors on his little scooter. There is quite a runway now, and he definitely takes advantage of it. But back to the review. We knew the basic idea of what we wanted, but we needed an architect to draw up the plans. We wanted to hire someone local, and Char was great. Char really knows the code requirements which helped a lot getting the plans through the permitting process. We drafted up a general floor plan before hiring Char, and she provided a lot of good ideas and helped us refine the design to work more efficiently in the given space. This turned out to be a lot more important than I thought because it?s hard to visualize how a space will flow and function from a simple floor plan. Char also knows a lot of professionals in the industry, which is great when it comes to engineering calculations, truss design, etc. We really like the neighborhood we?re in, and it was important for us that our new space match the character of the original house. You see a lot of remodeled houses that are cute in front, with a big ugly 2-story box sticking up in the back. We wanted to avoid this and worked hard to make the addition look like it was always a part of the house. We also wanted the house to retain its ?small? appearance from the front, and we didn?t want to use up all of our backyard either. We ended up with a perfect house. Our neighbor across the street who was born there in the late 1940?s told us he can?t even remember what the house used to look like - he said it really just looks like it?s always been there (and it?s only been 2 years). I would definitely recommend hiring Char if you need an architect or design help. Beyond her architectural skills, she is very personable and easy to work with. She came out to our house many times to review drawings with us, go over edits, and discuss various ideas. She was very accommodating, and even helped us get the plans through the permitting process. Thank you so much Char, we really love our new house, and couldn?t have done it without your help. Katie and Nathan Moxley West Seattle

Structural Engineering questions, answered by experts
Costs depend on material choices, labor, and the extent of structural modifications.
Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.
A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.
The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.
