"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

"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."

"I can not imagine a better architect to work with. Seth was attentive, detail oriented, exceptionally knowledgable, and prompt with his responses to every change we made. He went above and beyond, making calls on our behalf to engineers, getting pricing on windows and trusses. On top of all of that, he was extremely affordable, and I am certain he put in more hours than he charged us for. I can't imagine having done this project with out him."

Structural Engineering questions, answered by experts

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

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.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

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