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!"

Structural Engineering FAQs, answered by experts

A few hours for inspection, with a detailed report following in a week.

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.

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

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.

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.
