What Our Clients Say

5.0(23 reviews)
"We hired Triangle Structural Engineering during our home buying due diligence period after a home inspection raised some structural concerns. With deadlines closing in quickly, we needed a structural engineer who could respond fast, communicate clearly, and provide a thorough inspection and report. David exceeded expectations in every area. He was highly responsive, his pricing was competitive with other structural engineering quotes we received, and he was even able to complete the inspection the same day by giving up part of his evening to help us meet our timeline. The final structural engineering report was delivered in just 3 business days, much faster than other firms had estimated. Most importantly, David didn't just review the concerns from the original home inspection. He identified an even larger structural issue that had been missed entirely. Catching that problem now will likely save us a significant amount of money and stress down the road. The report itself was clear, detailed, and easy to understand. David also took the time to walk through the findings with me by phone the same day, explaining the concerns, potential impacts, and recommended next steps in plain language. Because I'm managing this home purchase and relocation process from out of state, quick communication and clarity were incredibly important. Triangle Structural Engineering made a stressful situation much easier to navigate. I would absolutely recommend Triangle Structural Engineering to anyone needing a structural engineer for a home inspection follow-up, foundation concerns, structural evaluation, or pre-purchase due diligence in the Raleigh-Durham Triangle area."

"We had TSE assess some cracks in our foundation. They promptly scheduled a visit with an experienced professional engineer. The inspection was thorough and the results were reviewed and explained so that we understood our situation. The written report provided good documentation and matched our prior discussion. TSE did a great job and we'd definitely recommend them."

"Was referred to David Hughes for doing a foundation inspection on my townhouse. He arrived in a timely manner, we had a great interaction with each other. We exchanged info as he was doing inspection. Great guy and submitted foundation reports and pics of issues in addition to a referral for the work and specs for repair work sooner than promised. Highly recommend David"
Carrie B.Google review
"David performed a structural assessment of a townhome that was experiencing some cracking and racked doors in one corner of the home. The inspection was very thorough. At the completion, David took me through his findings and recommendations. His explanations were easy to understand and his follow-up report detailing everything was issued in a timely manner (signed and sealed). I would highly recommend David and Triangle Structural Engineering if you have any structural concerns regarding your home."
Pam D.Google review
"David came out to look at the structural damage surrounding our fireplace caused by water leakage and gave us a very clear path forward for fixing it. We needed him onsite quickly, and he absolutely delivered for us. Reinforcement repairs were already underway within 24 hours of his visit. We're so thankful for his wealth of knowledge, responsiveness, and speed in helping us get this taken care of."
Julie H.Google review
"If working with a structural engineering firm with a vast depth of knowledge and experience is what your project needs then Triangle Structural Engineering should be your first (and only) call. You don't know it yet, but you've seen their work all across town, from residential new build and renovation to commercial scale. David is great to work with, ultra professional, explains things in terms laypersons and professionals alike can understand, and delivers highly detailed reports with quick turnaround. Look no further for your structural engineering needs."
Christian M.Google review
"Wonderful to work with! Professional, knowledgeable, and kind. They were very helpful to answer all my structural questions and were time efficient without making their visit feel rushed. I chose to go with them over a local competitor and highly recommend TSE. Thanks!"
Elizabeth C.Google review
"I contacted David Hughes after he was recommended by several people in my neighborhood. He came to my house and did a thorough inspection to determine if cracks in the wall should be concerning. In the process, he discovered a couple other issues that needed attention. A detailed report was prepared and passed on to my contractor. My contractor had questions which were easily resolved through several phone calls with David. After completion, I had David inspect the work during which he found some needed minor tweaks in order to give his stamp of approval. I found David to be responsive, knowledgeable, thorough and able to communicate in laymen's terms the issues. I highly recommend calling Triangle Structural Engineering should you need those types of services!!"
Jenny S.Google review
"David did an amazing job assessing my crawl space. He arrived slightly early and completed the inspection in a timely manner. He discussed with me the items he found, showing me pictures of the damage. The way he knew under which room the damage was located was impressive. The final report arrived when he said it would. If I need another structure engineer, David will be the 1st guy I would call."
KentGoogle review
"David Hughes and team provided enormous help and support getting a recent challenging residential redo completed. He examined the various issues and situations, determined options for repair(s), and then helped coordinate with the construction contractors thereafter to ensure all aspects were being handled correctly. Highly recommended."

FAQ

Common Questions

Answers to the questions homeowners ask most.

A structural engineer evaluates the load-bearing systems of your home - foundations, beams, walls, and framing. We identify problems, design solutions, and provide PE-stamped reports that contractors and municipalities accept.

Yes. Every inspection is performed by a licensed North Carolina Professional Engineer (PE) - never an intern, technician, or engineer-in-training. The same PE who walks your property writes and stamps your report. Triangle Structural Engineering is a licensed NC engineering firm (License #P-3406), and you'll always know exactly who is on site and signing off on your home.

Residential structural inspections range from $750-$2,000, based on the scope set by the licensed PE. Foundation evaluations, real-estate due diligence, and crawl space inspections are $750-$1,450, with most at $1,250. Wall assessments are $950 when non-load bearing or $1,250-$1,650 when a stamped beam design is required. A flat fee is provided before work begins.

Home inspectors provide a general overview of a property's condition. A structural engineer focuses specifically on the structural integrity - foundations, load paths, framing, and safety. If your home inspector flags a structural concern, that's when you call us.

Most inspection reports are delivered within 1-2 business days. Engineering design projects vary based on complexity, but we always communicate timelines upfront and prioritize fast turnaround.

You'll receive a clear, written, PE-stamped report that covers everything we observed during the inspection - including a description of the structural systems evaluated, our findings, photographs of any concerns, and specific repair recommendations with enough detail for a contractor to price and execute the work. Our report serves as a baseline so you can get multiple quotes from contractors with a uniform scope. Reports are accepted by local municipalities, insurance providers, lenders, and contractors throughout the Triangle area.

Absolutely. We regularly partner with general contractors, real estate agents, and home inspectors across the Triangle. Our reports are designed to be clear and actionable for all parties involved.

We serve the greater Raleigh-Durham-Chapel Hill Triangle area, including Wake, Durham, Orange, Johnston, and Franklin counties. If you're not sure whether we cover your area, just give us a call.

Yes - in almost every case, removing a load-bearing wall in North Carolina requires a PE-stamped engineering plan before a building permit will be issued. The wall may be carrying weight from the roof, floors, attic, or a combination, and a structural engineer determines what type and size of beam, column, and foundation element is needed to safely carry that load once the wall is gone. We regularly design header and beam solutions for wall removals, open floor plan conversions, and kitchen expansions throughout the Triangle. We'll provide stamped drawings your contractor can submit directly to the local building department.

Absolutely - and we understand the timeline pressure. We regularly work with home buyers, sellers, and real estate agents who need a structural assessment completed before a closing deadline. In most cases, we can schedule your inspection within a few days and deliver a clear, written report within 1-2 business days. Our reports are designed to be easily understood by all parties in the transaction - buyers, sellers, agents, and lenders. If your home inspector flagged a structural concern, that's exactly when to call us.

A structural engineer (PE) is licensed by the state of North Carolina to analyze and design the load-bearing systems of a building - foundations, beams, columns, load paths, and framing. We determine what needs to be built, perform the necessary calculations, and provide stamped drawings to prove it's safe. A general contractor is licensed to build it. The two roles work together - we design the structural solution, and the contractor executes it. On many projects, especially renovations and additions, the building department requires PE-stamped plans before issuing a permit.

The Raleigh-Durham-Chapel Hill area has clay-rich soils that expand and contract with moisture changes, which can cause foundation shifting and cracking over time. Older homes (especially those built before the 1990s) sometimes have undersized floor joists or beams that lead to sagging or bouncy floors. We also frequently see cracking in brick veneer, moisture damage in crawlspaces, and settling around additions where the new and original foundations meet. Most of these are manageable when caught early - that's why we recommend an inspection if you notice any changes in your home.

In most cases, yes. Wake County and surrounding municipalities typically require PE-stamped structural plans for any addition that adds living space, especially if it involves new foundation work, changes to the roofline, or adding a second story. Even when it's not strictly required, having a structural engineer involved from the beginning helps avoid costly surprises during construction - like discovering that existing footings can't carry the new load, or that floor joists need to be upsized. We work alongside your architect and contractor from design through construction to keep things on track.

Not all cracks are a cause for concern, but certain patterns should get your attention. Diagonal cracks near windows and doors, horizontal cracks in foundation walls, stair-step cracks in brick, and cracks wider than about 1/8 inch are more likely to indicate structural movement. Thin, hairline cracks in drywall - especially around door frames and corners - can be cosmetic, caused by normal settling or seasonal temperature changes. If you're unsure, that's exactly what we're here for. We'll evaluate the cracks in context - looking at the foundation, framing, soil conditions, and drainage - and tell you whether it's something to address or within normal ranges.

It depends on the crack. Hairline cracks from concrete curing are usually cosmetic, but horizontal cracks, stair-step patterns in block walls, or any crack wider than about 1/8 inch can signal real structural movement. A licensed PE will assess the crack pattern, measure displacement, evaluate soil and drainage conditions, and determine whether monitoring, minor repair, or engineered reinforcement is needed. Getting a professional opinion early can save thousands in future repair costs. If you've noticed new or growing cracks, schedule an inspection and we'll give you a clear, honest answer - typically within a few days.

Yes - and it's one of the most common reasons homeowners call us. We analyze your home's framing, roof structure, and floor system to determine exactly which walls carry structural loads. This matters before any renovation, especially open-concept conversions or kitchen expansions. If the wall is load-bearing, we design the replacement beam, columns, and connections needed to safely redistribute the weight. You'll receive PE-stamped drawings your contractor can use for permitting and construction. Don't guess - call us before you start demo day.

Our pre-purchase reports cover every major structural system: foundation condition, floor framing, load-bearing walls, roof structure, and any visible signs of movement or deterioration. You'll get clear photographs, plain-English findings, and specific repair recommendations with enough detail for a contractor to price the work. The report is PE-stamped and accepted by lenders, insurance companies, and municipalities across the Triangle. It gives you the confidence to negotiate repairs, adjust your offer, or walk away - whatever makes sense for your situation. Most reports are delivered within 1-2 business days.

A typical residential inspection takes about one to two hours on-site, depending on the size of the home and the scope of the concern. A licensed PE examines the foundation, crawl space or basement, framing, and any specific areas you've flagged - like cracks, sagging floors, or water damage. After the visit, we prepare your written report and deliver it within 1-2 business days. The entire process from scheduling to report in hand usually takes less than a week. Ready to get started? Give us a call or submit a request through our contact form.

In North Carolina, engineered drawings are typically required whenever a project affects the structural system of your home. That includes removing or modifying load-bearing walls, adding a room or second story, building a deck over a certain size, or repairing foundation damage. Most local building departments in Wake, Durham, and Orange counties won't issue a permit without PE-stamped plans for these types of projects. We work directly with your contractor to provide permit-ready drawings so there are no delays. If you're not sure whether your project needs engineering, contact us - we'll let you know in a quick phone call.

Absolutely - and smart sellers do. A pre-listing structural inspection gives you a clear picture of your home's condition before buyers bring their own inspectors. If there are issues, you can address them on your own terms and timeline, often at a lower cost than negotiating repairs under contract pressure. If the home is structurally sound, you'll have a PE-stamped report that builds buyer confidence and can speed up the closing process. Either way, you avoid last-minute surprises that kill deals. Contact us to schedule a pre-listing inspection - most reports are ready within 1-2 business days.
