One of the more specific challenges in renovating older Portland homes is trim. A Craftsman bungalow built in 1924 has door and window casing profiles that were standard at the time but have not been in production for decades. When you open a wall or add a door in a house like that, you cannot walk into a lumber yard and buy matching trim off the shelf. That is where our woodshop in Milwaukie comes in.
Why Standard Stock Profiles Do Not Match ¶
Trim profiles from the 1910s through the 1940s were milled to different dimensions than today's stock. The casing on a 1928 bungalow is often wider, with a more pronounced back bevel and a different ogee profile than anything you will find at a home improvement store. Installing modern stock trim next to original trim in the same room looks wrong immediately. The gap in the profile catches the eye even if the homeowner cannot articulate exactly why.
How We Identify the Existing Profile ¶
We start by pulling a sample of the existing trim, usually from inside a closet where it is less visible, and bringing it back to the shop. We measure the profile with a contour gauge and compare it against our reference library of historic profiles. If we have a match or close match in our knife inventory, we can run the new trim directly. If not, we grind a custom knife to match the profile. That adds a day or two to the shop timeline but produces an exact match.
Wood Species Matters Too ¶
Most original trim in Portland homes from this era is Douglas fir or old-growth pine. Both are denser and tighter-grained than the construction lumber available today. We source clear vertical-grain Douglas fir from a specialty supplier in the Portland area for trim matching work. It takes paint and stain the same way as the original material, which matters when you are trying to blend new trim into an existing painted interior.
When We Recommend This Approach ¶
Custom trim milling adds cost and time to a project. We recommend it when the existing trim is a significant part of the home's character and the new work will be visible in the same room or hallway. For work in a basement or a utility space, standard stock trim is usually fine. For a kitchen addition in a 1930s Craftsman where the new doorway opens into the original living room, matching the profile is worth the extra effort.
If you are renovating an older home and are concerned about matching existing trim or millwork, bring it up during the estimate visit. We will look at what you have and tell you honestly whether custom milling makes sense for your project.
