"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!"

"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."

"PegArch, LLC was hire for architectural plans, drawings, and construction assistance with a major home project. We found Mathew to be very easy to work with. He'd draw up some plans, review the plans with us, then modify the plans based on our feedback. He then kept in contact with City Planning officials, us, and the Contractor. He provided the plans to our Contractor. He visited the job site several times and noticed a problem with a dormer installation that was not being installed in the manner specified by his plans. He met with us and the Contractor on the job site , then made arrangements to correct the problem. I received compliments from City officials on Mathew's professionalism and great follow through, holding him in the highest regard. We also feel very lucky to have met and worked with Matthew Pegolo, as he is the most honest and helpful Professional we have ever encountered! Highly Recommended!"

Structural Engineering FAQs, answered by experts

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Yes, water damage can affect your walls' structural integrity. If the water or moisture sits on the walls for an extended period, it can weaken the drywall, plaster, wood framing, and other materials supporting the wall. That's why it's critical to dry out the area as soon as you notice it.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

If you intend to do the majority of the work yourself, you can pay to hire an architect or a structural engineer to ensure your home remains structurally sound. They can help with the planning to make sure everything is up to code and safe for your family. On the other hand, if you’re not sure your home will be completely safe when you’ve completed the project, let a pro do the job.

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.
