The fireplace is typically the first thing your eye goes to when you walk into a room. A well-built mantel and surround frames it the way the space deserves — it gives the fireplace visual weight, connects it to the room's architecture, and makes it feel like a deliberate design decision rather than a structural opening with trim nailed around it.
Grand Trim designs and installs custom fireplace mantels and surrounds for homeowners across New Jersey, working in a range of styles from traditional built-up mantels with pilasters and entablature to clean-lined contemporary surrounds with flat panels and minimal profile. The design is driven by the proportions of your fireplace opening, the ceiling height of the room, and the architectural character of the home. We work from your opening dimensions and talk through profile options, leg depths, and shelf heights during the in-home consultation.
Materials & Construction
Material choices typically include paint-grade MDF for painted applications, poplar for a blend of workability and durability, and hardwoods like white oak or maple for stained or natural-finish work. Surrounds that incorporate tile or stone work are built to accommodate the finished cladding, with precise reveals and transitions that tie the woodwork cleanly to the surrounding material. Built-up designs use stacked moldings and applied details to create depth and shadow lines that give a custom mantel its presence in the room.
Every component is cut, assembled, and installed to fit the specific conditions of your fireplace wall — not adapted from a stock mantel kit. Grand Trim is fully licensed and insured in New Jersey (NJ HIC License #13VH13073500), and every fireplace project ends with a walkthrough to confirm the installation meets your expectations before we leave.

A New Jersey Finish Carpentry Company Built on Craftsmanship
Our Working Process
In-Home Measure & Design Consultation
We visit the site to measure the fireplace opening, assess the wall conditions, and discuss style direction, molding profiles, shelf height, and material options. Tile or stone plans are reviewed at this stage so the surround is designed around them from the start.
Profile & Material Selection
Based on the consultation, we confirm the mantel design — leg style, entablature profile, shelf dimensions, and material. Proportions are worked out against your ceiling height and opening size before any fabrication begins.
Fabrication
Components are cut and assembled to the confirmed dimensions. Built-up molding profiles are stacked and glued to build depth, and all parts are checked against the shop drawings before moving to the install.
Installation
The mantel and surround are installed to the fireplace wall, plumb and level, anchored securely. Tile or stone reveals are set precisely so the woodwork lands cleanly at the cladding transition.
Caulk, Fill & Final Inspection
All joints are caulked, nail holes are filled, and surfaces are prepped for paint or finish. We walk through the completed installation with you to confirm everything is right before we leave.

Finish Carpentry & Custom Millwork Services
Grand Trim designs, builds, and installs custom woodwork for homeowners across New Jersey. Whether you need a full closet system, elegant wall paneling, or detailed crown molding, we tailor every project to your home, your style, and your space.
Built-In Shelving & Entertainment Centers
Built-ins add storage, structure, and character that freestanding furniture never can. Grand Trim designs and installs shelving and entertainment centers built around your exact space and how you use it.
Crown Molding & Trim Installation
Crown molding is one of the fastest ways to change how a room feels — but only when the corners are right and the profiles are proportional. Grand Trim installs it the way it's meant to look.
Kitchen Cabinetry
Kitchen cabinets are only as good as the installation. Grand Trim installs cabinetry that's level, square, and properly secured, with doors that align and drawers that close softly.
Wall Paneling & Wainscoting
Wall paneling transforms a flat wall into architectural detail. Grand Trim installs board and batten, shaker panels, raised panels, and wainscoting with clean lines and precise layout throughout.
Custom Closets & Wardrobes
We design closets around the way you actually live. Every shelf, drawer, and hanging rod is placed intentionally — built to fit your space exactly, not adjusted from a stock kit.
Baseboard & Shoe Moulding
Baseboard and shoe moulding are the finishing details that make a room feel complete. Grand Trim installs them with flush fits and clean corners — no gaps, no caulk-heavy coverups.
Mudrooms & Entryways
A well-built mudroom turns the most chaotic entry point in your house into a space that actually manages it. Grand Trim builds custom mudroom storage designed around your family's daily routine.
