Who builds custom wood front doors in Boulder County?

Spindle Woodworks, a woodworking shop in Longmont, Colorado, builds custom wood front doors for homes in Longmont, Boulder, Louisville, Lafayette, Erie, Niwot and Superior. Each door is designed for the house and drawn to scale for your opening before anything is cut, and you deal directly with Sam Claassen, who builds it.

Spindle Woodworks was founded in 2026 and is new to front doors: there are no finished customer doors to show yet. When the first one is done, its photos go here. Until then, what you can judge us on is the drawing for your own door and a straight answer to every question below.

What happens before anything is cut?

You see your door as a scale drawing first. Every door is drawn for its opening, with rails, panels, glass and hardware in proportion, so you can judge the design and change it on paper rather than in wood. A taller or wider opening gets a redrawn door, not a stretched one.

The doors are then cut on an Avid CNC router with an automatic tool changer, which cuts parts and patterns from a digital design. That matters most for panels, flutes and carved patterns: they can be cut exactly as designed, matched left to right, and cut again later.

How is a wood door built so it doesn't warp or crack?

Mostly by construction and finish, not by species alone. Wood swells and shrinks across the grain as it takes on and gives up moisture, and Front Range air is dry: the USDA Wood Handbook puts outdoor wood in Denver at 8.0% to 10.5% moisture content through the year, against 12.0% to 16.9% in Seattle (USDA, Table 13-1). Three things keep a door flat and tight:

  • Construction that controls movement. Simpson Door Company says its doors are built “in an engineered fashion”, with each part made of several pieces of wood under a veneer, “resulting in a sturdier, straighter door” (Simpson). Ask any maker how its doors are built.
  • A complete finish on every face and edge. Simpson tells owners to “coat all six sides of every door” (Simpson).
  • Light colors in strong sun. The Wood Handbook says darker finishes cause more solar heating, and so more warping and checking, than light ones (USDA, chapter 16).

Which woods can I choose?

For an exposed entry, genuine mahogany, sapele and white oak are the strongest all-round choices, and Douglas fir is the value choice. Our wood comparison sets out hardness, decay resistance and movement for each, with Colorado's dry air in mind.

What does a custom front door cost?

Cost guides put a basic custom exterior door at about $1,500 to $5,000 and a hand-built one at $5,000 to $20,000 (HomeGuide, checked November 2026). Glass, sidelights, hardware, finishing and installation are usually on top. HomeGuide adds that custom replacement through a specialty dealer “can often exceed $10,000, even for a simple door” (HomeGuide).

Pivot doorA wide, tall door that turns on a pivot set in from the edge.Size, pivot hardware and the floor and head that carry it. Custom pivot doors: $4,800 to $10,000 (HomeGuide)

Will a wood door hold up to Colorado sun?

Under cover, yes; in full sun with no overhang, it is a maintenance commitment. Simpson defines an adequate overhang as one that projects at least half the distance from the bottom of the door to the underside of the overhang (Simpson), and Sun Mountain, a door manufacturer in Berthoud, recommends “a non-wood alternative” for openings with high exposure to direct sunlight or moisture (Sun Mountain). Which way your door faces and how deep the overhang is are the first two things we ask. More in our wood door care guide.

What does a custom wood front door cost?

Cost guides put a basic custom exterior door at about $1,500 to $5,000 and a hand-built one at $5,000 to $20,000, before glass, sidelights, hardware, finishing and installation (HomeGuide, checked November 2026). Our cost guide breaks down what moves the price.

Are wood front doors a good idea in Colorado?

Under cover, yes. A wood door under an adequate overhang, finished on all six sides and kept up, holds up well. In full sun with no overhang it needs refinishing often, and some door makers recommend a non-wood door for openings with high exposure to direct sun or moisture.

Will I see my door before it is built?

Yes. Every door is drawn to scale for its opening before anything is cut, with its panels, rails, glass and hardware in proportion, so you can judge the design on paper first.
