"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."

Customers say: True 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.

"Ray didn’t just put in a whole new kitchen, including a pantry. He also ( I hope I remember everything) remodelled two bathrooms, put in a new front door, built steps into my garage, brought my washer & dryer up from the basement & installed it in my garage, helped us put together our gazebo. My favorite thing he built is our gorgeous large deck. We joke about it, it’s so well built that we’re holding onto it in a hurricane. Ray is so easy to work with, very caring & creative with suggestions. He has the nicest & very capable workers. We still stay in contact on a friendly bases, can’t say that about all contractors."

Unfinished Carpentry FAQs, answered by experts

If you remove a load-bearing wall to create an entrance to a carport or covered patio, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. Factors such as the type of addition and if that area needs additional work will add to the price.

Installing a tongue-and-groove wall requires similar techniques to those associated with installing shiplap. However, because of the precision necessary to make each board fit perfectly and the increased material prices, the cost is higher than that of shiplap installations. Expect to spend between $2 and $6 more per square foot for tongue-and-groove walls versus shiplap ones.

Removing a load-bearing wall affects the structural integrity of your home, so you’ll need a permit before starting the work. Building codes vary by municipality, and obtaining a permit and having the work inspected after completion will ensure you’re in compliance with all applicable regulations.

To calculate the number of linear feet of baseboard you’ll need, measure the length of each wall of the room you’re installing them in as close to the floor as possible, rounding up to the next full linear foot. If it’s your first DIY molding job, having a few extra feet on hand for miscuts is a good idea.

Converting a carport into a garage can vary in difficulty depending on its configuration, the condition of the foundation or slab, and its location relative to the house. The process has a lot in common with a home addition, but you can often skip non-essential finishes like fine flooring, trim work, or even drywall and HVAC. The conversion requires experience with drywall, insulation, and other building materials to ensure it’s done safely and correctly. While it might be possible for a DIYer with the proper tools and skills to do the work, it is a complicated and potentially dangerous job. If you’re new to basic construction, it's best to leave this project to the professionals.
