Custom Millwork & Built-Ins

Custom Millwork & Built-In Installation.

INSET BUILD installs custom millwork and built-in features — built-in cabinetry, shelving, benches, fireplace surrounds, architectural millwork, and other site-specific interior details. Homeowners and interior designers come to us directly for a single room or a whole-home set of built-ins, and builders, general contractors, and remodel contractors bring us in for millwork scopes on custom homes, townhomes, and remodels across Seattle, the Eastside, and King and Snohomish counties.

Built-in and custom millwork installation is fitted to the actual space, with layout, alignment, scribing, and finish transitions handled as part of the installation.

Jobsite

Built for the space.

We install custom millwork and built-in components from project plans, elevations, shop drawings, design details, finish schedules, and field conditions, coordinating installation with surrounding finishes and trades.

Built-in work often depends on the actual conditions of the space. Accurate layout, fitting, scribing, alignment, consistent reveals, clean joints, and transitions to adjacent walls, floors, ceilings, cabinetry, and trim are handled as part of the installation process.

We handle complete built-in and custom millwork installation scopes, coordinating the work with adjacent cabinetry, trim, walls, floors, ceilings, and other finished surfaces.

FAQ

Common questions.

Can homeowners hire INSET BUILD for built-in installation?

Yes. Homeowners hire us directly for built-in cabinetry, shelving, benches, fireplace built-ins, and other custom interior features, and we also install millwork scopes for builders, designers, and general contractors.

What types of built-ins and custom millwork do you install?

Built-in cabinetry and shelving, open shelving, benches and window seating, mudroom and entry built-ins, built-in work areas, bookcases, wall-to-wall and floor-to-ceiling units, fireplace surrounds and fireplace built-ins, and architectural millwork.

Do you build the millwork or install it?

Our work is installation and finish carpentry — layout, fitting, scribing, alignment, and finish transitions. We install millwork and cabinetry supplied by the homeowner, designer, builder, or cabinet shop, and we build site-fitted components and details as part of the installation.

Can you install built-ins in an existing home or remodel?

Yes. Existing homes and remodels are a large part of this work. Walls, floors, and ceilings are rarely square, so units are shimmed, scribed, and fitted to the actual space.

Do you work with interior designers?

Yes. We regularly install designer-specified built-ins and millwork, working from design drawings and elevations and flagging anything that needs a decision before installation.

Can you install from architectural plans, elevations, or shop drawings?

Yes. We install from supplied plans, elevations, shop drawings, design details, finish schedules, and specifications, and confirm layout against field conditions before installation.

Do you install fireplace built-ins, shelving, benches, and mudroom built-ins?

Yes. Fireplace surrounds and flanking built-ins, wall-to-wall and floor-to-ceiling shelving, bench and window seating, and mudroom lockers, cubbies, and hook rails are all regular scopes for us.

Do you take on built-in scopes for builders and general contractors?

Yes. Builders, general contractors, developers, and remodel contractors bring us in for defined built-in and millwork scopes on the project schedule.

What areas do you serve?

Seattle, the Eastside, and communities throughout King and Snohomish counties, along with Cle Elum and Suncadia.

How do I request a custom millwork or built-in estimate?
