The Making

Watch a door get built. Then decide what it's worth.

Timber Selection
01

The wood decides everything that comes after.

We buy air-dried European oak from the same sawmill we've used for eleven years. Each board is graded by hand — we're looking at grain direction, moisture content, and figure. Timber that will hold a mortise without splitting; timber that won't move once it's on your wall. Off-the-shelf doors skip this step entirely.

Air-dried 3+ years · 8–12% MC · Quartersawn stiles

02

Glue and screws are for furniture that doesn't matter.

Every joint in a Joinery door is cut by hand. The mortise is chopped with a mallet and chisel; the tenon is sawn and pared to fit. When the joint closes, you hear a soft pop of displaced air — that's the fit we're after. No biscuits, no dowels, no hidden metal brackets. Just two pieces of oak interlocked the way they've been interlocked for three hundred years.

Assembly & Glue-Up
03

Twelve clamps, forty minutes, no second chances.

The door goes together once. We dry-fit every joint before glue touches wood — checking square, checking diagonal, checking that the reveal will be consistent when it hangs. Then we mix the hide glue, work fast, and clamp in sequence. The door stays in the jig overnight. When it comes out, it's a door. Nothing moves after this.

Parallelogram jig · Diagonal tolerance ±0.5mm · 18hr cure

Craftsman bedding glass pane into linseed oil putty rebate
Glazing
04

Putty, not silicone. Light, not weatherproofing.

Traditional linseed oil putty is worked into the rebate by hand, the glass set and tapped home, then the face putty is knifed at 45° and left to skin for a week before painting. This is slower than silicone. It is also the only method that looks correct in a heritage opening and allows glass replacement without destroying the sash.

Finished bespoke French doors installed, afternoon light flooding kitchen, ironmongery catching sun
Installation
05

Hung, adjusted, and left clicking shut before we leave.

Our fitters have been hanging doors since before YouTube existed. The opening is prepared the day before; the door arrives packed in moving blankets. We set the hinges, hang the door, and plane the stiles to the reveal before ironmongery goes on. When we leave, both leaves close with the same pressure and latch without lifting. That's the standard.

Brass, bronze, or satin chrome ironmongery · Draught-sealed · 10-year structural guarantee
