Custom Carpentry Services in Bethesda and Rockville
Craftsmanship Built for Your Home
From floor-to-ceiling built-ins to hand-fitted crown molding and custom staircases, our carpenters add the details that make a house feel finished. Every piece is designed and installed to fit your exact dimensions and the architectural character of your home. Carpentry pairs naturally with our home remodeling, custom cabinetry, and custom closet work, and we often finish projects with a fresh coat from our painting services.

Carpentry for the Way DMV Homes Are Built
Bethesda
The mid-century split-levels and ramblers around Edgemoor and Bradley Hills often have low, compartmentalized ceilings, so we keep crown profiles in scale and build wall-to-wall media walls and bookshelves that make rooms feel intentional rather than crowded. It's a natural add-on to a whole-home remodel.
Rockville
The newer colonials and townhomes near King Farm, Fallsgrove, and the Pike District come with builder-grade trim and hollow doors. Swapping in deeper baseboards, casing, and solid-core doors is one of the highest-impact upgrades we do — and a perfect partner for a finished basement.
Potomac
The larger estate homes of Potomac and Avenel have the ceiling height and entry volume to carry statement work: two-story foyers, custom fireplace surrounds, coffered ceilings, and grand staircases with custom railings. We coordinate this millwork with your custom cabinetry.
Chevy Chase
Chevy Chase's older colonials and Tudors have real architectural character worth protecting. We match historic trim and casing profiles, restore worn stair treads and risers, and add period- appropriate wainscoting so new work blends seamlessly with the original details.
Silver Spring
From the bungalows and Cape Cods of the older Silver Spring neighborhoods to the newer condos and townhomes downtown, we tackle a wide range of carpentry — built-in home offices for remote work, pantry shelving and storage solutions that squeeze value out of compact floor plans, and door, window, and subfloor repairs that keep these well-loved homes solid. Many projects start with custom closets and grow from there.
Frequently Asked Questions About Carpentry in Bethesda
How much do custom built-ins cost in Bethesda?
Custom carpentry is priced by the piece and the materials, so the total depends on size, wood species, and finish. In the Bethesda area, a custom bookshelf or media wall typically runs about $2,500 to $8,000, a room of crown molding or wainscoting about $1,500 to $6,000, and a custom staircase rebuild about $5,000 to $20,000+. We provide a fixed, itemized quote after a free in-home measurement.
Do you build custom built-ins, bookshelves, and media walls?
Yes. We design, build, and install custom built-ins of every kind, including media walls, bookshelves, entertainment centers, home-office built-ins, pantry shelving, and built-in storage. Each piece is made to fit your wall dimensions, ceiling height, and the architectural style of your home.
Do you install crown molding, wainscoting, and trim?
Yes. Decorative carpentry is one of our specialties. We install crown molding, baseboards, custom wainscoting, door and window casing, fireplace surrounds, and other trim and molding work, matching profiles to the period and character of your home.
