Everything Your Home Needs — One Crew, One Call

Carpentry Services

Good carpentry holds a home together — literally and visually. Whether it is custom trim, structural repairs, door framing, or built-in work, D&J handles it with precision. Every cut is measured carefully and every finish is done cleanly. Sloppy carpentry shows, and that is never the standard here.

Door Installation & Replacement

A door that sticks, drafts, or simply looks worn down affects your whole home. D&J installs and replaces interior and exterior doors properly — level, sealed, and functioning the way they should. It is a small upgrade that makes a noticeable difference every single day.

Interior & Exterior Painting

Paint is one of the fastest ways to change how a space looks and feels. D&J preps surfaces properly before ever opening a can — no shortcuts. Interior or exterior, the finish comes out smooth, even, and built to hold up against Long Island weather.

Bathroom Remodeling

A bathroom remodel done right adds real value to your home. D&J handles the full process — tile, fixtures, drywall, painting, and finish work — so you are not coordinating five different contractors. The goal is a bathroom that works better, looks cleaner, and holds up long-term.

Kitchen Remodeling

Your kitchen gets more use than any room in the house. D&J remodels kitchens with that in mind — smart layouts, solid craftsmanship, and materials that can handle daily life. From cabinet work to tile and paint, everything gets done with attention to detail.

Interior Finish Work & Trim

Finish work is where a home goes from construction site to move-in ready. D&J installs trim, molding, and detail work that ties a room together. It is the kind of work most people do not notice when it is done right — and cannot stop noticing when it is done wrong.

Basement Finishing & Renovation

An unfinished basement is wasted square footage. D&J can turn it into a livable space — whether that is a family room, home office, or extra bedroom. Framing, drywall, flooring, and paint all handled by one crew who knows how to work with below-grade spaces.

Deck Building & Construction

A well-built deck extends your living space outdoors and adds real value to your property. D&J builds decks that are structurally sound, properly anchored, and built with materials that hold up through Long Island winters. No shortcuts on framing or footings.

Tile Installation

Tile work done poorly stands out immediately. D&J installs tile in bathrooms, kitchens, and floors with precise cuts, level lines, and clean grout joints. The prep work is done right the first time so tiles do not crack, shift, or loosen over time.

Power Washing Services

Years of dirt, mold, and grime build up on driveways, siding, and walkways without most homeowners noticing. D&J's power washing clears it all fast. It is one of the most cost-effective ways to improve how your property looks — inside of an afternoon.
