"Perry Brothers is everything you would want in a contractor- honest, knowledgeable, high quality workmanship. The plumbing in our house was originally done incorrectly and the original deck was structural unsound. They did a wonderful job fixing these problems and constructed a beautiful and safe new deck and two lovely new bathrooms. They also took care of some smaller projects we had around the house (patching, painting, etc). The foreman was great at communicating and always had a solution when he ran into issues (the former owners of our house left us with a lot of issues). We are very happy with the work and highly recommend Perry Bothers and will definitely use them again."

"Dennis did an excellent job. He was fast, accommodating (drove a long distance to measure my property, on short notice) and accurate. He was patient, explaining things to me that would help me use the drawings effectively. He recommended additional online tools for me to use to design my furniture layout. I highly recommend him."

"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."

Hi, I’m EDUIN,\n\nI am an experienced handyman with a professional background in architecture and property maintenance. This unique combination allows me to look at your home not just as a set of repairs, but as a complete structural system. I bring a high level of technical precision to every task.\n\nMy Experience:\n\nI have spent years working across both the design and physical upkeep sectors. My transition from architecture to hands-on maintenance means I understand the "why" behind how your home was built, which helps me solve problems more effectively than a standard quick-fix approach. From structural integrity to aesthetic finishes.\n\nWhere I Work\n\nI am based in Cape Cod, MA, and I proudly serve the local community. I am also available to travel to surrounding areas within a 30-mile radius for larger projects or scheduled maintenance.\n\nSpecial Skills & Expertise;\n\nArchitectural Insight: Ability to read blueprints and understand the structural needs of older and modern homes.

Structural Engineering questions, answered by experts

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

Indications include cracks in walls, uneven floors, and sticking doors or windows that suggest foundation movements.

Accurate measurements, sturdy materials, and seamless integration with other structures.

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.
