"I scheduled an appointment through Home Adviser, and Lawrence contacted me within five minutes, and we discussed my needs. We agreed on a time and date that was convenient and a reasonable price for the work. He arrived as scheduled to my residence. Lawrence is very courteous and knowledgeable. He listened to my concerns and was not in a rush. Lawrence thoroughly inspected the area and offered a solution that fit my needs. He explained his findings and how he would complete a report within 24 hours. He sent my report early the next day. I would highly recommend Lawrence if you are looking for an experienced structural engineer who has excellent interpersonal skills and delivers on his promise."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"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"

"He is a brilliant architect. I live in an old home which is always tricky. He designed our master bedroom in a 90 year old house in a way that didn't need any major structural changes. It looked as though the house was originally made for that design! The design he came up with also included everything down to the last detail. He does quality work and the guys he works with clean up after themselves. In the beginning of each project he extrapolates what it is that you are looking for. He doesn't try to push his latest design on you. His focus is solely on what each customer wants and he is very open minded to the taste of each client. He is incredibly efficient and I have never seen anybody work the way he does. Trent is very good at avoiding mistakes and his communications skills are excellent. He is very knowledgeable in his field, and because of that he completes projects very quickly and delivers high quality results. It is fun working with Trent because he makes it easy!"

Structural Engineering questions, answered by experts

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.
