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!"

"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"

"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."

Structural Engineering questions, answered by experts

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.
