Carpentry Services in Northridge, CA | GN Builders
Quality carpentry is what separates a finished home from a truly polished one. From structural framing to decorative trim, built-in shelving to custom woodwork, skilled carpentry touches nearly every part of a home remodel or new construction project. GN Builders provides full-service carpentry for homeowners throughout Northridge and the San Fernando Valley — rough framing and finish carpentry handled by the same licensed general contracting team.
Carpentry Services We Offer
Rough Framing
Every addition, ADU, room conversion, and new construction project starts with structural framing. We frame walls, floors, roofs, and openings — installing headers, beams, and posts correctly sized for the load they carry. Proper rough framing is the foundation everything else is built on.
Interior Trim & Molding
Baseboards, door casings, window casings, crown molding, chair rail, and wainscoting transform a plain room into a finished space. We install trim cleanly — tight miters, no gaps, properly nailed and filled before painting.
Crown Molding Installation
Crown molding is one of the most impactful finish details in any room, and one of the most difficult to install well. We cut compound angles precisely and install crown that sits tight to both wall and ceiling — no caulk-filled gaps hiding bad cuts.
Built-In Shelving & Bookcases
Custom built-in shelving integrates seamlessly with your walls and looks far better than freestanding furniture. We build and install floor-to-ceiling bookcases, entertainment center built-ins, closet shelving systems, and home office built-ins sized exactly to your space.
Wainscoting & Wall Paneling
Board and batten, shiplap, raised panel, and flat panel wainscoting add texture, character, and protection to walls in dining rooms, hallways, bedrooms, and mudrooms. We install paneling systems that are level, evenly spaced, and properly finished.
Stair Construction & Repair
Stairs require precise carpentry — stringers, treads, risers, and railings must all be dimensioned correctly for safety and code compliance. We build new staircases for additions and multi-story ADUs, and repair existing stairs with squeaking, damaged treads, or failing railings.
Door Installation & Hanging
A door that swings true, latches cleanly, and gaps evenly around the frame is the mark of a skilled carpenter. We hang interior and exterior doors — prehung and slab — and adjust existing doors that have dropped, swollen, or warped.
Window & Door Casing
Casing frames your windows and doors and is the first thing visitors notice about a room’s finish quality. We install casing in styles ranging from simple contemporary profiles to detailed traditional assemblies with plinth blocks and head casings.
Deck & Pergola Framing
Wood decks, pergolas, and covered patio structures require sound structural framing before any surface material goes on. We frame decks and overhead structures to code with proper post bases, beam connections, and joist hangers.
Custom Woodwork & Specialty Carpentry
Coffered ceilings, tray ceilings, decorative beams, fireplace surrounds, window seats, and mudroom lockers — if it’s built from wood, we build it. We work from your design or develop one based on your goals and budget.
Rough Carpentry vs. Finish Carpentry
Many homeowners aren’t sure which type of carpentry their project needs — or realize mid-project they need both.
Rough carpentry is structural — walls, floors, roofs, beams, headers, and subfloors. It gets covered by drywall, flooring, and cladding and never seen in the finished home, but it determines whether the structure is sound, level, and square.
Finish carpentry is everything visible — trim, molding, built-ins, doors, and decorative woodwork. It’s what defines the quality and character of the finished space.
GN Builders handles both, which matters on remodeling projects where rough and finish carpentry overlap and need to be coordinated.
Why Choose GN Builders for Carpentry?
Licensed General Contractor — License #1134674. Structural framing and load-bearing work require a licensed contractor in California. We’re not a handyman service — we’re a full general contracting team.
Rough and Finish Under One Roof — On remodeling projects, the same team that frames your walls installs your trim. No miscommunication between subcontractors about rough opening sizes, wall thicknesses, or finish details.
Precision Matters — Carpentry mistakes compound. A wall framed out of plumb shows up in the flooring, the trim, and the cabinetry. We take the time to get structural work right so finish work goes smoothly.
Clean Jobsite — Carpentry generates sawdust and scrap. We clean up at the end of every workday and haul debris regularly so your home stays livable during construction.
Free Estimates — We review your project, discuss material and style options, and provide a written estimate at no charge.

Frequently Asked Questions — Carpentry Services
Do I need a permit for carpentry work?
Finish carpentry — trim, built-ins, doors — does not require a permit. Structural framing work (new walls, beams, opening modifications) does require a permit in LA County. We determine what’s needed and handle all permit applications.
Can you match existing trim throughout my home?
We do our best to source matching profiles, but older homes often have trim that is no longer in production. In that case, we can have custom profiles milled to match, or recommend a compatible contemporary profile. We always show you options before proceeding.
Can you build a coffered or tray ceiling?
Yes. Coffered and tray ceilings are built-up carpentry structures applied to the existing ceiling. They dramatically change a room’s character and perceived height. We assess your ceiling’s existing height and structure and design a coffered grid that’s proportional to the room.
