"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."

"The process working with Char to develop a set of design plans for my master suite addition has been fantastic. She has worked with me step by step, explaining the process at each point and what I can expect. She also listened to what I was looking for, drew up various designs, and then worked with me on modifications. She was a partner in the process the entire time, not only treating me with respect and professionalism, but talking through options and pros and cons with me so I ended up with the design I really wanted. Throughout the entire process I felt like I was in good and trustworthy hands. So much so that I will continue to use Char's assistance as I move forward on next steps with this project."

"I used Triple V as the Project Engineer for a garage conversion to single family residence for my son’s family. Vic not only did the engineering for us, he also did the structural drawings we submitted to the county as part of our permit package. He delivered the plans promptly, and worked collaboratively with us to resolve issues we identified and revise the drawings accordingly. The county building department approved the plans and issued the permit. During the project construction Vic patiently responded to questions from us (we’re DIY’ers, not professional builders) and offered/provided certifications to revisions we jointly agreed to. Overall, Triple V provided what was promised at an outstanding value."

"This company is fabulous. We did a remodel and addition to an existing home. When we ran into problems with local building regulations, Alex worked with us to create the floor plan and did the revisions promptly and at a very reasonable fee. We would happily recommend his company. A definite 5 star company."

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. 

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.

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Proper licensing and experience in residential and commercial structural projects.
