"Silvino Mendez assigned us 2 excellent flooring professionals to do the job (Ivan & Alex). Very professional, experienced, on time, neat, and friendly, too! I was very impressed with Ivan’s suggestions as to the job, esp since the product we purchased on our own was not up to par. We went with them to get Luxury Vinyl Plank Flooring at another flooring place and it worked out perfectly. He Evan called them twice to see what colors they had in stock so job wasn’t delayed. Job was still done on time despite having to return the initial materials and obtain credit. Ivan recommended we get shoe molding as appears in the pics and he painted them a beautiful grey that we had mixed to match at the store. These moldings set the finished look. We are very impressed. Silvino phoned in several times during the process to his contractors and myself. When install was complete, he came to the house to view everything with his flooring professionals and myself. Nice work!"

"We were extremely pleased with the entire process. Matt is professional, organized and a superior craftsman. His crew was the same. Remodeling is loud and messy - there's no way around that - but Matt and his crew were always respectful, pleasant, and cleaned up each day. Their work is exceptional. Matt plans well and always kept us informed of what to expect next and when. Planning for deliveries (like cabinetry) with COVID was tricky, but we were well informed of any challenges and we could plan our lives around it. Older houses always come with surprises, but Matt was always patient to explain things and then give us options so we could make informed decisions. We got exactly what we wanted - but were pleasantly surprised at how smooth things were handled and ecstatic at how beautiful the results are. His attention to the smallest details sent it above and beyond our expectations. We would recommend Matt and his crew to anyone and would use him again most definitely."

FAQs for second story addition building service projects in NEPTUNE, 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.
