"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."

"Des Moines Area Roofing was professional, trustworthy, and demonstrated excellent attention to detail from initial contact to job completion. Cleanup was so thorough that the next day you wouldn't even know that such a major project had taken place. It has been 2 weeks since the new roofs and we haven't seen even one stray nail left behind (and they did a complete tear down to both buildings, right down to the wood). An excellent company with which to do business. I offer my highest possible recommendation."

"Andres Martinez and his crew with Cesar and Adan did a phenomenal series of jobs at our home. They put in a beautiful and functional driveway, designed and constructed a very nice fire pit, and made a nice pad for our bbq grill. We were very pleased and impressed with their timeliness, professionalism, skills/talents, courtesy, and attention to detail. The pricing that Andres provided was very good and competitive with others. We will hire he and his team in the future for additional projects. We give them a 9.5 out of 10. You will not go wrong hiring this team for your next project!"

"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"

Structural Engineering questions, answered by experts

Most load-bearing walls are exterior, though they can also be interior.

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

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

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.
