Custom Architectural Millwork

Made in Seattle Since 1889

No job is too big or too small.

We sell to anyone and ship anywhere. From a single stick to match an existing moulding to a complete prefinished millwork package, O.B. Williams makes custom architectural woodwork in Seattle.

Wood moulding profile samples organized in the O.B. Williams profile library in Seattle.

Custom Mouldings & Millwork

From a single replacement profile to millwork for an entire home, O.B. Williams manufactures custom mouldings in a wide range of species, sizes, and profiles. With nearly 10,000 profiles in our library, we can often match an existing pattern—or create a new profile when needed.
