Interior Wood Refinishing in Colorado Springs: Bringing Old Trim, Doors, and Built-Ins Back to Life

Old-growth fir, quartersawn oak, and old pine trim in Colorado Springs’ historic homes can almost always be refinished instead of replaced, and refinishing is the right call nearly every time: this wood is denser, more dimensionally stable, and simply doesn’t exist in new lumber today. I recently saw a 1920s craftsman bungalow in Old Colorado City with 5-inch fir baseboards, deeply profiled and perfectly intact under forty years of paint, where a previous contractor wanted to rip it all out for 3.5-inch colonial base from the lumber yard. That’s the wrong call every time refinishing is possible.

When Is Refinishing the Answer?

Stained wood trim that has darkened, dulled, or worn unevenly. The finish is gone but the wood underneath is fine. Strip the old finish, assess the wood, and apply a fresh stain and topcoat that either matches the original or takes the color somewhere new.

Painted trim over quality wood. This is the most common situation in Old Colorado City, Broadmoor, Manitou Springs, and the older parts of Ivywild and Palmer Heights. Layers of paint hide the shaped detail in the molding, fill in the crisp grooves that give it depth, and cover wood that’s worth seeing. Stripping back to bare wood and refinishing in a natural or tinted clear finish transforms the room.

Doors with layers of old finish. Interior doors in historic homes hold their shaped detail through many rounds of refinishing. This is especially true of the paneled fir doors common in Colorado Springs craftsman and colonial revival houses. A door that looks tired under a worn-out finish often looks extraordinary after stripping.

Built-in bookshelves, window seats, fireplace mantels. These are irreplaceable. A Victorian fireplace mantel with its original profile work cannot be sourced new for any reasonable cost. Refinishing it takes it from tired to extraordinary.

What refinishing can’t fix: Wood that’s swollen from moisture, cracked all the way through, or so badly checked that the surface is ruined. (Checking is the web of cracks that opens up along the grain as wood ages and dries out.) It also can’t fix damage to the shape itself: gouges, dents, or missing pieces of molding. Those have to be filled or remade before refinishing can work. That call gets made at the start, not the end.

The Process: What Actually Happens?

This is where most people underestimate the work, and it’s the part I have the hardest time explaining before a client sees it in person. Refinishing isn’t sanding and recoating. Done correctly, it’s a multi-stage process with no shortcuts.

Step 1: Chemical stripping. When paint sits over stained wood, the right stripper soaks in and lifts the old finish without roughing up the wood or wearing down the molding’s shape. (A stripper that “raises the grain” leaves the wood fibers standing up and fuzzy, which means extra sanding later.) Gel strippers work well on vertical surfaces and detailed moldings because they cling in place instead of running off. The stripper sits on the surface for a while, then comes off with plastic scrapers and bronze wool. Not steel wool: steel leaves tiny bits behind in the wood that rust and stain later.

Step 2: Detail work. Shaped moldings have tight inside corners and narrow grooves that stripper alone won’t fully clean out. This is where the work gets fussy: dental picks, narrow scrapers, and careful hand work to reach into the grooves without rounding off the crisp edges. On a piece of trim with four different shaped elements, this takes time. Rush it and the old finish stays behind in the recesses, where it clearly shows.

Step 3: Sanding. Once the old finish is off, the wood gets sanded evenly so the whole surface soaks up stain the same way. Flat surfaces are easy. Shaped parts have to be sanded along their curves, using foam sanding blocks, shaped sanding sticks, or sandpaper wrapped to follow the contour. Flat sandpaper pressed onto a curved molding flattens the curve and wipes out the detail.

Step 4: Stain. If you want the natural wood color, you can skip this step. If you want a specific color (matching trim elsewhere in the house, a new tone, or an on-purpose contrast), this is where it happens. Oil-based stains soak into the wood and let the grain show through. Getting the color right on old wood takes testing on a hidden spot first. Old fir, old pine, and old oak each take stain differently than modern lumber, and the difference is big.

Step 5: Topcoat. The topcoat is the clear protective coat that goes on last, and it sets both the final look and how well the finish holds up. Oil-based polyurethane is the toughest option and the most practical for surfaces that get touched and bumped a lot, like baseboards, door frames, and railings. Water-based polyurethane dries faster and has less of a yellow-amber tint, which makes it better for very light or near-white stain colors. The topcoat comes in different sheens, from matte to satin to gloss. It goes on in several thin coats, with a light sanding between coats using fine paper.

Colorado’s Climate and Wood Finishes

Colorado Springs has very low winter humidity, often just 10-20% relative humidity indoors, and sometimes single digits. That is harder on wood finishes than most climates, and I see it show up in the same spots over and over. When humidity swings quickly, wood shrinks and swells, and that stress lands on the finish at every joint and shaped edge. This is why so many historic homes show cracked or failing finish at the corners of door casings and at the mitered joints of baseboards (the angled 45-degree corner joints). Those are the spots that move the most.

The right topcoat for Colorado has some give to it. A finish that dries completely rigid tends to crack at those high-movement points. Oil-based polyurethane stays a little more flexible than water-based, which is one reason it’s the traditional pick for interior woodwork in dry climates. The other reason is its amber tint, which warms up the wood and gives old fir and oak their rich, deep color.

What Gets Overlooked in Wood Refinishing?

Hardware. Original hardware on historic trim (the hinges, the door knobs, the window latches) is often cast brass or bronze that got painted over. It’s almost always worth cleaning and refinishing that hardware as part of the job, instead of swapping in reproduction pieces that won’t match the original quality (I push clients toward saving the original hardware every time, and I’ve yet to have one regret it).

Matching the molding shape. When a section of historic trim is too damaged to save and has to be replaced, matching its shape matters. Many original molding shapes aren’t sold anymore, so they have to be custom-cut on a milling machine. We can order custom-milled molding or hand-shape replacements to match the original before refinishing pulls it all together.

The whole room, not just the worn section. Refinishing one stretch of trim in a room where the rest keeps its original finish rarely blends in. The old finish has shifted color over the years from age and sunlight, and fresh finish won’t match it right away. For the best result, aim for whole-room consistency: either refinish all the trim in the room, or plan for a toning-and-blending step that brings everything to the same look.

Every refinishing project gets a written flat-rate estimate after we’ve looked at the wood, the existing finish, and how much prep it needs. The condition of what we’re working with sets the cost, not a formula.
