Our Services

Custom Kitchen


Safety, hygiene and comfort are the characteristics of every successful kitchen. Given that it is one of the most used rooms in your home, the kitchen is also more prone to visible aging and wear and tear.

Renovation and remodeling is often the solution to a fading kitchen. Operating in Suffolk County, New York, John J Contracting’s professional team of expert kitchen remodeling specialists can undertake any renovation work your kitchen requires.


Custom Bathroom


Have you considered getting your bathroom renovated? Your bathroom can be made to be as appealing as the rest of your home. Our expert team of bathrom remodelers will help you make the most of the space you have and transform it into something practical, modern, user-friendly, comfortable and elegant.

John J Contracting will build your bathroom as you imagined it; whether it is your own design or one you saw in a magazine.


Custom Deck


As is the case with clothing, interior decor fashion trends change frequently. Of course, you can hardly be expected to transform your interiors with every change of season, but after a few years, when the curtains start to fade and look dull and the furniture begins to creak, you might consider replacing or upgrading them.

John J Contracting’s experienced team is here to draw up the perfect home interior remodeling plan for you and your family.
