"During wind storm a tree fell on out buildings. A garage and 2 sheds. This company was fast in tarping garage roof to keep rain from getting in. Also, Anwar was quick to give estimates on repairing garage roof and sheds. His crews put new roof on garage and sheds as well as replacing broken rafters caused by the tree. They prepped and painted garage and sheds. They look brand new. Anwar interfaced with my insurance company to get additional considerations from the original insurance estimate. I was especially appreciative of his help. You can't go wrong by hiring Dluxe Construction!!!"

"I contracted with TVP for engineering plans for a home addition in February, 2023. The sales person Phil McDodson, made an agreement to stay with the project through to the permit but walked away as soon as the county required additional information. At that point Janae Spinney stepped in and would not quit on me until that promise was complete. A special thanks to Joseph and Caleb for getting us through to the end. Every engineer and staff member with TVP was polite, knowledgeable and saw the job through. It was just approved January, 2025. Great company and I appreciate all you did for us!"

"Matthew Bruce exceeded our expectations. Our 92-year-old dad fell while using the bathroom and injured himself. We needed an immediate response to make the bathroom safe. Matthew responded to my request very quickly. He asked questions about the situation that showed he had the expertise we needed. He came to the house within a day of agreeing to perform the work and completed the most urgent task that day. He needed other tools to complete the installation of the grab bar drilled into the shower tiles, so he had to return at a later time. He communicated clearly when he could return and completed the task. Additionally, he cleaned up after his work and was pleasant to workMatthew Bruce exceeded our expectations.

"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."

"Juan helped us design and plan a 4-plex on a small lot in a prime location. He met with the city and sorted out the codes we could use (duplex with 2 ADUs), and worked with us and the city the whole way through our work together. His plans made good sense, and he gave us space to think about it, talk about it and come back with thoughts that he would incorporate when we could. I feel like we had good control of the process, and he is a pleasure to work with. Thank you, Juan!"

Structural Engineering questions, answered by experts

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.
