Design For Living Contracting is a privately owned company that is run primarily by owner Benjamin Maltzman. The employees of DFLC have been working together for a number of years, and have a healthy and close relationship with the owner. DFLC does not sub-contract jobs to any contractor, for we actually avoid sub-contracting at all costs. DFLC does "sub" out a small portion of its contracts to only two other companies, one of which is an active angle's list contractor with service awards since 2010, and the other who is backed by major companies like Lowes home improvement. Both companies have worked very closely with DFLC, and have provided only quality work in association with our company. DFLC accepts all cash, check, and money order payments. Specifics on billing details are stated in contracts, and are dependent upon job size, budget and deadline.

"Design for Living Construction was outstanding! Their work is excellent! They were very transparent and they finished on time. I would hire them again in a heartbeat! Ben was great to work with!"

"Contacted National Home Improvements regarding leaking patio roof and no follow up response to issue since last year of April 2023. Still awaiting to hear back. Seems like the rain gutter is sagging in the middle of the patio where the two joints meet and water is pooling there and possibly leaking through the seams as illustrated in the photo. Poor design concept. Really disappointed with customer service and quality of product especially for what we have paid for. They clearly don't care about taking care of their customers. I would never hire National Home Improvements again!!!"

Classical Pavers serves both New Jersey and New York in the Tri-state area. We are masonry contractor company that specializes in the installation of outdoor living areas including paver driveways, walkways, patios, steps, stoops, retaining walls, culture stone, and fire pits. We are fully insured.

"Classical Pavers did a beautiful job replacing my front walkway! It was not a straightforward project because it was built on a steep slope with a curve. The owner Thiago, who oversees the project, was a pleasure to work with -- never used any pressure tactics, was very responsive to any questions, and gave a fair price. The two craftsmen who did the work were amazing! They arrived promptly every day, worked extremely hard, and did absolutely beautiful work. They hauled away all the old materials and tidied everything up when the job was done. We definitely would hire them again for a future project and highly recommend them."

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