Surprise odds are approximate planning estimates, not measured rates; cost ranges are sourced where shown. How this works.
Each cost line is drawn from a triangular distribution and correlated by a shared market factor (~0.5); the most-likely value and range emerge from the simulation, not the band. A planning simulation, not a quote.
New to door replacement?
A door replacement is usually a 1-day project but several pieces drive the price: door type (entry, sliding, French, garage), material (steel, fiberglass, wood, vinyl), and whether you need a full pre-hung unit (with frame) or just a slab. Energy savings are modest — 1-3% of HVAC — but the comfort, security, and curb appeal gains are real. Fiberglass entry doors are the modern default for most homeowners.
Frequently asked questions
How much does it cost to replace a front door?
Steel basic $500–$1,450 installed. Fiberglass mid (most popular — Therma-Tru, Pella, JELD-WEN) $800–$2,300. Premium fiberglass with sidelights $1,500–$3,600. Solid wood $2,000–$5,300. Full pre-hung replacement (frame + door + threshold) adds $300–$800 over slab-only.
What about sliding patio doors?
Vinyl 6ft 2-panel basic $1,200–$2,900. Fiberglass premium (Pella, Andersen) $2,600–$6,600. Wood premium (Andersen 400, Marvin) $4,300–$10,700. French double doors $2,500–$6,700. Old single-pane sliders losing seals are the most cost-effective replacement target in older homes.
Is there a tax credit for energy-efficient doors?
No, not in 2026. The 25C credit for ENERGY STAR exterior doors (was 30% up to $250 per door, $500 total) expired Dec 31 2025 (OBBBA). Some utility programs in MA, NY, OR still offer $50–$200 rebates on Class A doors but most ended. ENERGY STAR ratings (U-factor ≤ 0.30) still matter for comfort but don’t come with a federal subsidy.
