"ESG Design was great to work with. I contacted them through Home Advisor for an impartial assessment of the cause of cracks in my ceiling, plus a few other issues. Eli, the engineer, did a thorough inspection and developed a solid plan for repairs. ESG also offered two levels of fees, which was extremely helpful for my budget. Thank you ESG for the service and peace of mind!"

"Ward Engineering began working with Jared of Cornerstone Home Designs approximately 3 years ago to perform residential design work using Chief Architect design software. I find Jared to be the most capable Chief Architect designer I have ever worked with. Jared is very efficient and thorough at developing the residential Chief Architect models. In addition to being competent, Jared makes himself available to provide personal 1-on-1 training over the internet, which has been a huge blessing to our company and clients."

"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."

"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."

"Josh has always been prompt and communicative with every interaction we've had. I initially got in touch with him about new construction design questions, and when we discovered that our current home porch posts had rotted through due to faulty design by the original home designer, Josh jumped into action. He had his engineer and construction crew to our door within 24 hours to take a look and put together a plan. He took my design ideas and brought them to life. He was transparent about all parts of the cost (to include his profit), and gave us to option to lower the cost by hauling away debris and painting the porch (which we were more than willing to do). Any delays with the work were met with a phone call and followup email if he didn't get through to either my husband or I immediately, and the construction crew did very high quality work. We were beyond pleased with his customer service! We will definitely use Revival Home Designs in the future when we decide to build our forever home."

Structural Engineering questions, answered by experts

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.

Costs depend on material choices, labor, and the extent of structural modifications.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.
