How much do built-in bookshelves cost?

Why there’s no single price

Built-ins are made to fit one wall in one house. They’re not a box off a shelf, so the price follows what you actually want built. A pair of shelves on either side of a fireplace, a full wall in a family room, a window seat with shelves above it, and a basement media wall are all built-ins, and they take very different amounts of material and time.

The things that set the price

Size and shape

Width and height matter most. A floor-to-ceiling unit needs more material and more work to scribe (trim the edges to fit) against an uneven ceiling and walls. Units that wrap around a corner, a window or a doorway take more fitting than a straight run.

Open shelves or cabinets below

Open shelves are the simplest. Adding closed cabinets at the bottom, with doors, hinges and adjustable shelves inside, adds a lot of work. Drawers add more, since each one needs its own box and slides. Many homeowners like a mix: cabinets at the bottom for the clutter, open shelves above for books and photos.

Materials

Painted built-ins are usually made from paint-grade plywood and MDF (medium-density fiberboard), which stays flat and paints smooth. Stained built-ins need real hardwood or hardwood plywood with matching edges, which costs more and takes tighter joinery because there’s no paint to hide seams. Shelf thickness matters too. Long shelves loaded with books need to be thick enough, or supported well enough, not to sag.

Details and trim

Face frames, crown at the top, base trim at the floor, beaded panels on the sides and the style of the cabinet doors all add up. Simple shaker doors take less time than raised panels or glass doors. Matching the new built-in to the existing trim in your house can take custom work.

Extras

• Lighting inside the shelves or above them
• A desk section or a bench seat
• Openings for a TV, speakers or wiring
• Hardware: knobs, pulls, hinges
• Outlets moved or added, which may need an electrician

Paint or stain finish

A good painted finish on built-ins takes several steps: filling, sanding, priming and finish coats on every shelf edge and inside corner. It’s a real part of the cost, and it’s the part everyone looks at. We do it as part of the job so the paint matches the rest of your trim.

The wall behind it

What’s behind the built-in can change things. Long Island houses often have walls that are out of plumb and floors that aren’t level, especially in older capes. We shim the base level and scribe the sides so the unit sits tight with no gaps. If the wall needs work, or you want built-ins in a new framed alcove, that’s part of the price too.

Doing it with other work

Built-ins often come up as part of a bigger job, like a basement, a family room or a home office. Building them while the room is already torn up can save steps. Outlets and lighting can be planned before the walls are closed, the trim can match, and painting happens once for the whole room. If you’re planning other work, mention it when we come out so we can price it all together.

Built-ins versus store-bought

A tall bookcase from a store is cheaper, but it leaves gaps at the ceiling and sides and never quite lines up with the room. Built-ins fill the whole space, use the corners, and look like part of the house. They also stay with the house when you sell, which matters to some buyers.

How to get a real number

Before we come out, it helps to have a rough idea of what you’ll store (books, TV, toys, files), whether you want doors or open shelves, and a photo or two of a style you like. We measure the wall, check it for level and plumb, and talk through options. Then you get a written, itemized price with a start date and how long the job will take.
