"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."

"Evolution design worked with me on designing and addition for a 100 and 5 year old house. We worked on the dimensions of the addition Plus the materials. Evolution understood the local zoning which was amazing that they knew that. We have not started construction. And evolution can help pull the permits and I'm considering them for that as well. All in all it was a long project but it was done efficiently, working with several of the staff an the departments."

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

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

A structural engineer's report provides a professional assessment of a property's structural condition. It typically includes an evaluation of the foundation, key structural elements like roof trusses, floor joists, studs, beams, and rafters. The report will also contain a detailed description of the engineer's findings, often supported by photographs, and provide recommendations to correct any identified issues. Depending on the scope of the inspection, it might also include an assessment of property drainage, potential issues from environmental conditions like extreme weather or tree placement, and an estimated time and cost for any recommended repairs.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.
