Customers say: Quality work

"Was having a potential home inspected for structural integrity. Spoke to Bob on the phone a few times. Since the home’s basement primarily consisted of a giant crawl space, I was told Don would do the job. Ultimately, the day before the scheduled inspection, I couldn’t get ahold of Don. Bob said Don was “feeling sick,” so the job was off. Frustrating, but a blessing in disguise because we ended up going with Colonial Restorations (the home was built in the 1800s). Colonial Restorations, LLC is the “go-to” for older home inspections and repairs. Tom was amazing (his son Brad is soon to take over the business)! They were both prompt, professional, and thorough. Very pleased with their work and thorough report/estimate. Colonial Restorations, LLC PO Box 868 Fiskdale, MA 01518 508-735-9900"

"In renovating our beach cottage in Warwick, RI we found the roof needed structural work. Building inspector required a structural engineered plan. Adam was easy to communicate with. He was timely with his plan and follow up inspection. He was also available by text and phone for questions during the project. He was great to work with!"

"After an unusual situation arose at my home, I was concerned about the possibility of structural damage caused by drilling and new construction at an adjacent lot. After receiving a recommendation for Veitas Engineers from a trusted source, I called and scheduled an appointment. I am so thankful that I did. I continue to be impressed with the amount of time that the two engineers spent at my house, closely inspecting the exterior and interior. Within days, I received a 16-page detailed report which included drawings, photographs, recommendations, and action items. I was so pleased when I saw that the action items were categorized as structural and non-structural, that is, that the engineers included items beyond my actual structural concerns. I used the report when working with a contractor to follow up on the recommendations and action items. The contractor was impressed with the quality, clarity, and scope of the report. I am so happy that I chose Veitas Engineers!"

"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."

"We had an exceptional experience working with Michal on our house extension project. From the very beginning, he demonstrated an outstanding ability to translate our vision into a functional, beautiful design that seamlessly blends with the existing structure. His attention to detail, creativity, and deep understanding of both aesthetics and practicality made the entire process smooth and enjoyable. What truly stood out was his communication and responsiveness—he was always available to answer questions, provide updates, and offer thoughtful suggestions that improved the overall outcome. He collaborated effectively with our sub-contractors, engineer and interior designer and ensured that every stage of the project stayed on track, on budget, and in line with local regulations. The final result has exceeded our expectations. The new space feels light-filled, spacious, and perfectly suited to our family's needs. We receive compliments on it from many people! I wouldn't hesitate to rec"

Structural Engineering FAQs, answered by experts

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

A freestanding brick wall that's only one brick thick can usually stand six to eight feet high. If you need a higher wall, it should be at least two bricks thick for adequate stability, and it might require a footing to support the added weight. Additionally, some areas have regulations and codes dictating how high a brick wall can be, so check with local code enforcers to ensure your proposed wall complies with any regulations.

Yes. Foundation walls are always load-bearing.

Proper licensing and experience in residential and commercial structural projects.
