"The work went very well. Lou is very knowledgeable, professional and easy to work with. He inspected my house thoroughly and explained my concerns in great details. He went beyond and explained some of the common non-structural issues on an old house. He also suggested on the proper ways to fix them.

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

High end architect specializing in making a house feel like home!\nI make people’s dream homes a reality. There is nothing more satisfying to me then improving the quality of life for my clients and giving them a house that they are able to make into their homes.\nI have been a licensed architect since 2015 and am currently registered in Rhode Island, Connecticut, New York, Maine and Massachusetts. With my NCARB certificate I am able, if necessary, to obtain reciprocal licensure throughout the country in a short time period. \n\nI am inspired by our local built environment, humble materials, classical building forms and traditional building details. I have a strong interest in the reinterpretation of classical building forms, blended with contemporary open floor plans. \nI have a stronger interest in helping to guide my clients to ways of improving the quality of their lives through adapting the built environment to meet their needs.

Structural Engineering questions, answered by experts

Costs depend on material choices, labor, and the extent of structural modifications.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

Structural engineers can perform various inspections on different structures in your home. These inspections usually include a report detailing the engineer’s findings and recommendations for repairs so you can determine your next course of action for repairs, replacements, or new builds. Some of the most common structural engineering reports include:

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.
