Exterior Door Replacement Cost Guide
Exterior door replacement is an opening and weather-control project: door unit, jamb, threshold, flashing, hardware, trim, security, and the condition of the surrounding wall.
Interior estimator controls
Scope the opening, not only the door slab
Record the opening width and height, handing, swing, threshold, sidelites or transom, frame condition, exterior cladding, interior trim, and access. A slab swap is different from a prehung replacement that changes the jamb, threshold, weather seal, and surrounding finish.
Carry removal and disposal, shimming, flashing, pan or sill treatment, insulation, trim, paint or stain, lockset, deadbolt, closer, screen or storm door, and threshold transitions as separate decisions. Rot or water damage can change the opening work after removal.
- Slab, prehung, French, sliding, storm, or specialty opening.
- Jamb depth, sill, flashing, weather seal, lockset, and hardware.
- Trim, siding, masonry, drywall, paint, stain, and threshold repair.
- Security, egress, accessibility, delivery path, and disposal.
Use the supported estimator rather than a nonexistent calculator
There is no separate exterior-door calculator. Open the remodeling estimator, choose an interior project context such as Room or Whole House, and use its existing Doors material control. Mark which doors are exterior in the project notes so the product allowance and opening work remain understandable.
The estimator can organize quantities and allowances; it cannot certify a weather seal, security rating, fire separation, egress path, or structural opening. Final selection and installation should follow the product instructions and local requirements.
| Option | Best for | Watch for |
|---|---|---|
| Slab replacement | A sound frame and jamb where dimensions, reveal, hardware, and weather seal remain suitable. | Exact fit, hinge and bore locations, threshold, strike alignment, and hidden rot. |
| Prehung replacement | A project that needs a new jamb, threshold, weather seal, or opening correction. | Trim, siding or masonry repair, flashing, shimming, insulation, and disposal. |
Permit and locality checklist
Exterior opening, egress, fire separation, historic review, accessibility, and energy requirements vary by jurisdiction and property. Confirm local requirements and have the installer verify the opening before ordering. This guide is planning information, not a code determination.
