Front Door Replacement With Sidelights: Cost and Options
With sidelights (the narrow glass panels beside a door), you can replace just the door, a prehung door in its frame, or the entire entry system. Sidelights or a transom alone typically add $1,600–$4,600.
Three levels of replacement
| Option | What gets replaced | Good when |
|---|---|---|
| Door slab only | Just the door, hung on the existing frame | Frame and sidelights are solid and square; matching sizes are available |
| Prehung door | Door and its frame; sidelights stay | Door frame is damaged but sidelights are fine |
| Full entry system | Door, sidelights, frame and sill as one unit | Rot, drafts or leaks at the frame or sill; you want a matched look |
Costs
| Item | Typical cost |
|---|---|
| Steel door (product) | $150–$1,400 |
| Fiberglass door (product) | $150–$3,000 |
| Fiberglass entry door with new frame | $470–$4,090 |
| Sidelights or transom | $1,600–$4,600 |
| New exterior door frame | $130–$380 |
| Old door removal | $40–$200, plus about $60 disposal |

Things to check
- Rot in the sill, the bottom of the frame or the subfloor below it, which is common at older entries.
- Glass options: decorative, privacy or impact-rated, and low-E for energy efficiency.
- Whether the new system fits the existing opening or needs framing changes.
- Lock and hardware: multipoint locks and a reinforced strike plate improve security.
- Storm door compatibility, if you have or want one.
