How to Tell If a Contractor Can Actually Remodel an Old House
Published
Portland has a lot of old houses. Irvington, Laurelhurst, Alameda, Ladd's Addition, Eastmoreland, the West Hills. Whole neighborhoods built before 1940, still standing, still full of the details nobody puts in houses anymore.
If you own one and you're planning work, here's the uncomfortable part: being a good contractor and being a good contractor for an old house are two different skills. Plenty of builders who do excellent new construction will quietly damage a period home, not through carelessness but by defaulting to how new houses get built.
Here's how to tell the difference before you sign anything.
Ask how they'll match the plaster
This is the single best question, and it takes thirty seconds.
Most pre-war Portland homes have plaster walls, and many have a hand-applied texture: swirled, combed, troweled, something a person did by hand in 1928 and never wrote down. If your project moves a wall, widens a doorway, or cuts a new opening, that texture has to be continued into the new work.
There is no product that reproduces it. You can't order more. Somebody has to stand there, read the existing pattern, and work the new plaster by hand until the seam isn't findable.
Listen to how they answer:
- "We'll match it by hand, and we'll do a sample board for you to approve first" is the good answer.
- "We'll patch and texture it." They're thinking of drywall texture spray. That will not match.
- "We'd probably just skim the whole wall smooth." They're proposing to remove the thing that makes your house your house.
A flat patch next to ninety-year-old texture is the most common way a period remodel gives itself away, and it's permanent. Every visitor's eye will find it forever.
Ask what they plan to keep
A good old-house contractor volunteers a list of what they want to save before you ask. A risky one talks only about what's coming out.
On a 1928 Spanish Revival we remodeled in the West Hills, the kitchen, butler's pantry, laundry and four bathrooms were all rebuilt from the studs. What didn't move: the arched openings, the barrel-vaulted entry, the textured plaster, the stained glass over the front door, the original entry lantern.
We also built the new pantry cabinetry around the home's original cast-iron radiators rather than pulling them out. That's harder and it takes longer. It's also the reason the room still reads as belonging to that house.
The distinction that matters: replace what has failed or was never good. Keep what can't be bought. Finishes, fixtures, cabinets, tile, wiring, plumbing: replace freely. Plaster, millwork, hardware, glass, tile that was hand-made, anything original to the period: fight for it.
Ask what they expect to find behind the walls
Anyone who says "shouldn't be any surprises" on a pre-1940 house has either not opened many of them or isn't being straight with you.
Old Portland houses commonly turn up knob-and-tube wiring, galvanized supply lines that have narrowed to a straw, framing that isn't plumb or level anywhere, and previous remodels done to nobody's standard. Sometimes there's asbestos or lead paint, which brings its own testing and handling requirements and is not something to guess about.
None of that is a reason to panic. It's a reason to want a contractor who says it out loud in advance and tells you how those items will be priced and approved when they surface, before they surface, while you're still calm and nobody's holding a demo bar.
The bid isn't the useful document. The process for handling what's behind the wall is.
Ask to see an old house they've finished
Not a portfolio of kitchens. A period house, finished, ideally one where they had to blend new work into old.
Then look at the transitions, where new meets original. Doorway edges, wall corners, where new flooring meets old, where a new opening was cut. That's where the skill is or isn't. Anybody can make a new kitchen look good in a photo. Very few can make you unable to tell where the new work starts.
A note on "bringing it up to code"
You'll hear this phrase, and it's often correct. Work you permit generally has to meet current code, and that's a good thing, especially for electrical.
But it's also sometimes used to justify removing original material that didn't need to go. If a contractor tells you something historic has to be destroyed for code reasons, it's fair to ask them to point to the specific requirement, and fair to check with the city yourself. Sometimes the answer is genuinely yes. Sometimes "code" is doing work that "easier for us" should be doing.
What good looks like
The best compliment a period remodel can get is that a visitor can't tell it happened. The kitchen works like it's 2026. The bathroom has a shower that drains properly and a fan that actually moves air. And the house still feels like the house.
That's the whole job. Everything else is negotiable.
