"It was amazing 🤩 I made a call to MAS and Harold and Lauren were at my home the next day. Harold, Pete and Gabrielle were extremely hard working and so courteous and such a joy to work with!! I actually was so pleased with the deck that I asked for a quote on vinyl fencing. I would strongly recommend this company for any work needed. It means so much when the actual owner of the company comes and does the work alongside his employees. I did happen to see one horrible review from someone who was 100% 😑. It was actually the only bad review so clearly it was not the fault of MAS but rather the idiot that posted such an incredibly inaccurate and incorrect review. I will definitely recommend this company to my family and friends and take it from me, I can really be a PITA when things are getting done at my home but not once was I ever meant to feel like I was being a PITA. The customer service skills of Harold and Lauren and their team is remarkable!!!"

FAQs for second story addition building service projects in Riverton, NJ

Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location. 

Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.

Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications. 

Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.

Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents. 

These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.

Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases. 

Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
