"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."

"We recently had a complete roof replacement. Before proceeding, we did comprehensive research of area companies and Vista came out on top, with good reason! All appointments were not only on time but were extremely punctual. We met first with Product Specialist Holly, who was enthusiastic, very knowledgeable and helpful. While at our home assessing the proposed job, Project manager Rick explained the entire process in layman's terms. The day of the job, Project Supervisor Marc arrived early and went over the entire job with the crew. All company representatives left us with a business card with their cell #'s to call if we required anything. The installation crew was amazing. They arrived early and began immediately. They were no nonsense, very focused and, worked like a well oiled machine. All Vista team members were polite and respectful of my special request to be cognizant around some of my more cherished trees & shrubs. Vista was fastidious in their care for my home and lawn, not one speck of debris was left behind. Vista, the installation crew, company representatives, everyone, exceeded our expectations. Vista stands behind their work and products. If you wish to relax after a major home improvement project knowing the job was done correctly, you will want to consider Vista. Dan & Kim Belchertown"

"In summary I have to say Richard was  excellent!  He came when he said he would and finished the work when he said it would be finished.  As I solicited multiple bids for the work NE Renovations was among the most competitive.  As the work was completed I was so pleased I ended requesting he come back to do additional jobs.  He was very accomadating and even explained various options on how best to accomplish the additional work.

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

Structural Engineering questions, answered by experts

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

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

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.

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.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.
