"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"Dennis was very helpful in the designing of our retirement home. He was welcome to revisions and clarifications at a very reasonable price. I would highly recommend him to anyone seeking design of a single-family home."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

"I've decided to do the work myself with some help from my son. The price was way more than I thought it would be and I could use some natural materials and spend less money. The representative from the company was professional and knew his product but, over $ 14,000 for a tub/shower replacement was way more than I wanted to spend."

Structural Engineering questions, answered by experts

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.

Indications include cracks in walls, uneven floors, and sticking doors or windows that suggest foundation movements.

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.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.
