How Custom Door Orders Work: From Specification to Installation

October 13, 2026 – 3 min read

Ordering custom doors allows you to achieve the exact aesthetic, dimensions, and architectural performance required for your project. Whether for modern residential homes or commercial properties, the process follows a structured workflow to ensure quality, precision, and seamless installation.

1. Consultation & Initial Specifications

The process begins with defining your project requirements and design intent:

  • Dimensions & Openings: Measuring the exact height, width, and wall thickness of the rough opening.

  • Material Selection: Choosing the appropriate material based on location and exposure (e.g., solid teak wood, engineered timber, aluminum frames, or glass panels).

  • Design & Style: Defining the aesthetic—ranging from traditional carved panels to minimalist flush doors, pivot doors, or sliding barn configurations.

  • Performance Requirements: Specifying soundproofing (STC rating), fire rating, weatherproofing, or enhanced security locking mechanisms.

2. Technical Drawings & Approval (CAD / Shop Drawings)

Once the specifications are set, technical shop drawings are created for review:

  • Detailed Schematics: Detailed CAD drawings show elevations, cross-sections, frame details, hinge placements, and clearance allowances.

  • Hardware Integration: Planning for handles, locksets, concealed hinges, or automatic door closers.

  • Client Sign-off: The buyer or architect reviews and approves the technical drawings to confirm every dimension before production begins.

3. Material Sourcing & Manufacturing

After sign-off, the manufacturing phase starts in the workshop:

  • Kiln Drying & Timber Preparation: For solid wood doors, raw timber undergoes kiln drying to achieve optimal moisture content, preventing warping or cracking over time.

  • Precision Cutting & Joinery: CNC machines and skilled craftsmen cut the profiles, joinery joints (such as mortise and tenon), and hardware mortises.

  • Assembly & Quality Inspection: Panels, rails, and stiles are assembled and checked for squareness, structural strength, and flush tolerances.

4. Finishing & Pre-fitting

  • Sanding & Staining: The door surface is sanded smooth and treated with stains, veneers, clear polyurethane coats, or custom paint colors.

  • Pre-drilling Hardware: Hinge cutouts, locksets, and drop-down seals are pre-machined to ensure a smooth, hassle-free installation on-site.

  • Protective Packaging: Finished doors and frames are carefully wrapped with protective foam and moisture-resistant packaging for safe transport.

5. Site Delivery & Professional Installation

  • Site Preparation: The installation team verifies that the rough opening is clean, level, and dry.

  • Jamb & Frame Mounting: The door frame/jamb is anchored, plumbed, and squared using shims.

  • Hanging the Door: The door leaf is mounted onto its hinges or pivot system, and hardware is installed.

  • Testing & Calibration: The door is tested to ensure smooth swing/slide operation, proper latching, and uniform gaps all around.
