Fireplace Remodeling Nassau County NY — Built-Ins, Surrounds & Shiplap Walls
A fireplace wall is the most visible surface in your home. When it’s wrong — a poorly proportioned mantel, builder-grade surround, flat drywall with nothing flanking it — it pulls down every room it’s in. Creatively Done Homes Improvements Inc. has been designing, fabricating, and installing custom fireplace millwork across Nassau County and the Oyster Bay area since 1986. This is the level of detail and planning that turns a basic fireplace into a finished focal point.
The typical Nassau County home — ranch, split-level, Colonial — came with a fireplace that was never really designed. A basic brick surround. A stock mantel from a catalog. Flat drywall on either side with nothing filling the space. It functions, but it doesn’t do anything for the room. The fireplace wall is the focal point of every room it’s in. When it’s underwhelming, the entire room feels unfinished — no matter what you put on the floors or the adjacent walls.
Fireplace remodeling in Nassau County isn’t just about swapping a mantel. Done correctly, it transforms the entire room: proportions, storage, architectural character, and how the space functions day to day. Kevin has been building custom fireplace surrounds, flanking built-ins, and full wall millwork treatments across Nassau County and the Oyster Bay area since 1986 as part of a broader approach to home remodeling in Nassau County that puts finish quality first. Every project is designed from scratch for the specific room, the specific homeowner, and the specific proportions of the space.
From a Blank Wall to a Room-Defining Built-In — Locust Valley
This project started with a 14-foot wall in a Locust Valley family room that wasn’t doing its job. The fireplace was there. A poorly executed mantel and surround were there. Two IKEA-quality bookcases flanked it — completely out of proportion with the room and the zip code. The wall had potential. It just hadn’t been realized.
The homeowners had already done the right homework. They’d worked with an interior designer to develop a millwork elevation drawing — a professional rendering showing exactly what the wall should become. Two lower cabinets flanking the fireplace. Two open bookcase sections stacked above. Shiplap behind the TV and fireplace. Crown at the ceiling. It was well-conceived. It just needed someone who could actually build it.
The shiplap went in first — 8-inch boards, spacing and joint lines dialed in on-site to read correctly at scale across a 14-foot wall. Then came the cases. The bookcase spans were 42 inches — wide enough that shelf thickness becomes a structural question, not just an aesthetic one. Kevin used the Sagulator, a shelf deflection calculator used by fine furniture makers, to determine that 2.5-inch thick shelves were required to carry a real book load without sag. That thickness became the design language for the entire piece — both sides of every case were built to match, giving the millwork a consistency and weight that catalog pieces never achieve.
Cases and cabinets were fabricated off-site, prepped and primed before delivery. After installation, Kevin set up a spray booth on-site and applied three to four coats of Sherwin-Williams cabinet paint in Wedding Veil White, sanding between each coat. The result is a finish you’d find in a high-end furniture showroom — smooth, hard, even, and built to last decades without the brush marks or roller texture that brush-applied paint leaves behind. The wall that used to disappear into the background now anchors the entire room.

What Fireplace Remodeling Actually Involves
Fireplace remodeling in Nassau County covers a wide range of scope. Some projects are surround-only — the existing fireplace opening gets a new tile or stone surround and a properly proportioned mantel. Others are full wall treatments like the Locust Valley project above, where the entire wall is redesigned around the fireplace. Here’s what each component involves.
Custom Fireplace Surrounds
The surround is the millwork frame immediately around the fireplace opening — the legs, the frieze, the mantel shelf above. Most stock surrounds are thin, poorly proportioned, and made from MDF that won’t hold up long-term. Kevin designs and builds custom surrounds from solid wood, sized to the specific opening and the specific room. Proportions matter: a surround that’s too narrow looks spindle-thin; one that’s too wide overwhelms the opening. Getting it right requires experience, not a catalog.
Flanking Built-Ins
The space on either side of a fireplace is almost always underutilized — flat drywall or, at best, freestanding furniture that doesn’t quite fit. Custom built-in bookcases and cabinets designed specifically for those flanking spaces give the wall architectural integrity and add real storage. The built-ins need to relate to the fireplace surround in proportion, detail, and finish — otherwise they look like an afterthought. When they’re designed together as one system, the result is a wall that looks like it was always meant to be exactly that.
Shiplap & Feature Wall Treatments
Shiplap behind a fireplace and TV gives the wall texture and depth that drywall can’t provide. The spacing of the joints, the width of the boards, and how the shiplap integrates with the surrounding millwork all affect how the finished wall reads. Too tight and it looks busy. Too wide and it loses the effect. Kevin works out the spacing on-site based on the specific wall dimensions — there’s no universal formula that works across every room.
Tile & Stone Surrounds
The fireplace opening itself is often faced with original brick, dated ceramic tile, or builder-grade stone that doesn’t match the style of the room. New tile or stone around the firebox opening — coordinated with the millwork surround above — completes the transformation. Kevin coordinates all tile work as part of the overall home remodeling project.
TV Integration
Mounting a TV above a fireplace without planning the wall around it produces a cable mess and a TV that looks bolted on. When the TV is planned into the design from the start — with blocking built into the wall framing, cable management routed through the wall, and the shiplap or millwork designed around the screen dimensions — the result looks intentional. The Locust Valley project is a good example: the TV is centered in the shiplap field, the mantel shelf is positioned at the right height below it, and the built-ins on either side frame the whole composition.
The Difference Between Furniture-Grade Millwork and Everything Else
Most contractors who offer built-ins are finish carpenters — they assemble and install. Kevin designs, engineers, fabricates, and installs. That full-cycle capability produces a different result.
A 42-inch shelf loaded with books will sag over time if it isn’t built to the correct thickness. Kevin uses the Sagulator — a shelf deflection calculator used by fine woodworkers — to determine the minimum thickness required for any given span and load. Cases and cabinets are built and primed in the shop before they come to your home, which means tighter joinery, better quality control, and less disruption on-site. After installation, Kevin applies Sherwin-Williams cabinet paint in multiple coats via spray, sanding between each. The result is a furniture-grade finish — hard, smooth, and even — that brush or roller application can’t produce.

Frequently Asked Questions
What does fireplace remodeling cost in Nassau County?
A custom surround and mantel runs $3,000 to $8,000. A full wall treatment with flanking built-ins, shiplap, and crown molding runs $12,000 to $30,000+. The range is wide because every wall is different — dimensions, storage requirements, wood species, and finish level all affect the final number. Kevin provides a detailed written estimate after visiting your home. No guesses over the phone.
How long does a fireplace remodel take?
A surround and mantel replacement takes 2-4 days on-site. A full wall treatment with built-ins, shiplap, and spray finish takes 2-3 weeks from fabrication through final coat — including off-site cabinet building, on-site installation, and the spray finishing schedule with sanding between coats. Kevin provides a project timeline during the planning phase so you know exactly what to expect at each stage.
What adds the most value in a fireplace remodel?
The biggest value comes from treating the fireplace as a full wall system — not just replacing the mantel. A properly designed fireplace wall includes a correctly proportioned surround, integrated built-ins for storage, and a finished wall treatment like shiplap or paneling that ties everything together. When those elements are designed as one cohesive unit, the entire room feels finished and intentional. That’s what separates a basic upgrade from a true room transformation.
Is it worth adding built-ins around an existing fireplace?
In almost every case, yes. Flanking built-ins transform a fireplace from a single feature into a full architectural wall. They add storage, they anchor the room, and they’re one of the few upgrades that raises the perceived quality of an entire home — not just the room they’re in. For Nassau County homeowners in Syosset, Jericho, and the Oyster Bay area especially, built-ins are expected at the price point of these homes. A wall without them looks unfinished by comparison.
Can you add built-ins to any fireplace?
In most cases yes — as long as there’s adequate wall space on either side of the firebox. The built-ins are designed around the fireplace opening, the ceiling height, and the room’s proportions. Kevin assesses the wall during the estimate and tells you exactly what’s possible and what the best configuration would be for your specific space.
Stock surrounds vs. custom — what’s the real difference?
Stock surrounds are built to generic dimensions and made from MDF that swells, cracks, and fails at paint joints within a few years. Custom surrounds are built from solid wood to your fireplace’s exact opening size, with proportions designed for your specific room and ceiling height. The difference shows immediately — in how it fits, how it’s finished, and how it holds up. Custom isn’t always more expensive than you think, and it lasts indefinitely.
Do I need a permit to remodel a fireplace in Nassau County?
Millwork work — surrounds, built-ins, shiplap — does not require a permit. If you’re modifying the firebox itself, changing the flue, or converting from wood-burning to gas, that work requires permits from your local building department — either the Town of Oyster Bay or the Town of Hempstead depending on your community. Kevin identifies what permits are needed during the estimate and advises on the full process.
Can you work from a designer’s rendering or inspiration photos?
Yes — and this is often the best way to start a project. If you’ve worked with an interior designer and have a millwork elevation drawing, Kevin can build directly from that drawing. If you have inspiration photos from Houzz or Pinterest, he can reverse-engineer the design and adapt it to your specific wall dimensions. The Locust Valley project started with exactly that combination — an interior designer’s elevation drawing and reference photos from a finished project the homeowners admired.
Do you serve Oyster Bay, Locust Valley, and the North Shore?
