"We hired Perry Bros for exterior updates to our home and were very pleased with the outcome of the project. The work involved removal of an elevated deck and 2 long brick walkways with steps, replacement of all exterior wood trim covering 3 floors above ground, construction of a new stone patio and walkways with steps, the rebuild of a screened porch (with custom-made doggy door and ramp), and exterior painting of the full structure and all trim. Workers showed up when scheduled, cleaned up well each day, and were respectful and courteous of us and our home. They worked diligently through more than one heatwave, keeping the project on schedule. We were always kept well informed of progress and the inevitable issues that arose and were provided with options to accommodate our budget and preferences. Communication with Bill Perry and project manager Mike was great whether by phone, email, or text. We’ve greatly enjoyed using the new outdoor space and have received many compliments on the appearance and quality of the work. We feel comfortable recommending Perry Bros and will not hesitate to hire again for future projects."

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

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

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)

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.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.
