Exterior Door Replacement Cost in 2026: Front, Patio & French Door Prices

Exterior door pricing in 2026 covers a huge range: a basic steel slab swap runs under $900, while a French pre-hung system with sidelites tops $4,000 in high-cost US metros. Fiberglass pre-hung units remain the most-installed choice because they beat steel on insulation and wood on rot resistance.

FAQ

How much does Home Depot charge to install an exterior door?

Home Depot's 2026 flat install fee for a standard pre-hung exterior door runs $400–$650 nationally, plus the door unit. Rot repair or framing changes are quoted separately.

Fiberglass vs. steel exterior door — which is cheaper?

Steel is $300–$500 cheaper up front but dents and rusts. Fiberglass costs more but insulates better and lasts 30+ years, making it the better long-term value for most homes.

Do I need a permit to replace an exterior door?

A same-size door swap usually doesn't require a permit. Enlarging the opening, changing the header, or adding sidelites almost always does — expect $75–$200 in permit fees.
