"Tom at TAS Engineering was professional, friendly, helpful, patient and highly competent and efficient. He did the assessment of my attic structural issue and identified the simplest and most cost-effective solution. He ensured that my contractor did the work to his specifications and provided the certified engineering letter that all had been addressed properly. This was exactly what I needed. I would highly recommend him and would hire him again."

"Darren was professional and courteous. He called to let us know he was running a bit late. He was great at explaining things and very thorough. He got an official report to us in a timely manner. But most importantly he assured us the house we were about to purchase was structurally sound. He even suggested ways to keep the small structural shifts in the older home from occuring."

"After a nightmarish experience with a crooked contractor, I was left on my own to obtain plans and a permit for my unfinished deck. I reached out to ISTA - their structural engineer Pedram has been nothing short of amazing. He came to my property to verify measurements to make sure the drawings would meet code, spent a great deal of time observing all structures and pointing out in great detail everything that needed to be fixed for safety reasons (things that were missed by my city inspector), offered alternatives to costly fixes, then worked very quickly to draw plans as he empathized with my situation. He even called the city's building department and got everything resolved on the spot. Five minutes after his call, my permit was approved!! And through all this, Pedram was so friendly and empathetic. Everyone in that office I spoke to has been very nice as well. I will definitely use ISTA again for all my future projects."

"Michael was a great find for architectural drawings for our Pop-Top remodel. He was far more affordable than other options, and though he offers a standalone architectural design service (meaning we had to separately obtain structural engineering plans), he was extremely helpful in pointing us in all the right directions. He was responsive and patient at every step of the process, and his designs turned out great!"

"We had a great experience working with Vital Architecture and highly recommend her. For Little Village Childcare, she helped us save money by confirming certain landlord requests were not required by code and securing a waiver that saved space and costs. She also reduced civil engineering expenses by preparing the playground drainage plan herself. During construction, she provided extra support at no cost and helped us handle contractor changes wisely. For another church childcare project, she identified zoning issues early so everyone understood the risks. In Colorado Springs, she warned a tenant about higher plumbing costs required by childcare regulations, helping them avoid a bad lease. For an adult care project, she reviewed the food area and explained new kitchen and ventilation requirements. Carmen is knowledgeable, thorough, and truly looks out for her clients’ best interests."

Structural Engineering FAQs, answered by experts

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

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.

Yes, unresolved damage can decrease property integrity and market value.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.
