"I have never had the experience of remodeling a kitchen; and from what I had heard from people who did a remodel; it was a horrendous experience. I can truly say Homecraft(Norman) advised me through the entire process and I have nothing but positive feedback to give anyone who asks me. Norman’s staff of electricians and Dal his contractor were quite talented and professional. Overall I would highly recommend Homecraft for any remodeling project."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.







Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. 

Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. 

This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.

I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

Unfinished Carpentry FAQs, answered by experts

You can choose 5/8-inch plywood or 3/4-inch plywood—anything thinner than these sizes may not withstand the impact of debris propelled by strong winds or can be easily torn off by intruders. Remember that the durability of the wood board is crucial, particularly for safeguarding your windows during severe storms. The effectiveness of using wood boards for protecting the investment you made in your home relies on using the appropriate material and ensuring proper installation.

Framing with metal studs can be significantly faster than using wooden studs, provided you have some experience working with the material. While you can use virtually instant pneumatic nailers with wood, metal requires installing screws. However, because metal is lighter, straighter, usually comes cut-to-length, and doesn't require sorting for the best pieces, you can save significant time using metal instead of wood.

Framing a house with steel generally takes less time—around five to eight weeks—than most building materials. The steel components can also be made quickly off-site and manufactured with pre-punched holes for running piping and electrical wiring, which will lessen the prep work and extra labor during construction.

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.

It’s sometimes safe to replace a load-bearing wall with a beam, but you need a structural engineer to sign off on the project. You’ll also likely have to upgrade to a steel I-beam or another material that’s stronger than wood to maintain the level of support you need without the wall underneath.
